Marcel Huibers about 20 years high wire cucumbers

Labour still main challenge

 

Marcel Huibers, manager of Hortus in Futuro in Maasbree, experienced the introduction of high-wire cucumber cultivation up close. At the start of this development, Huibers worked at Nunhems as a sales specialist in cucumbers. Between 1999 and 2015 he specialized in high-wire cultivation. Together, with the growers, he looked for opportunities and came up with solutions.

At BASF Vegetable Seeds the year 2020 is dedicated to 20 successful years of cucumber breeding for high-wire cultivation. It is therefore high time for a review of this development and a visit to Huibers. In the video, he talks about the initial phase, how he experienced this period and how he looks at the future. “The greatest challenge of high-wire cultivation in cucumbers is still labour”, says Huibers

Powdery Mildew, Whitefly, TPP, Light and Irrigation

Drought is over and mushrooms are growing

 

In the last month I have observed the rapid outbreak of Powdery Mildew.  The rain has returned, and mushrooms are sprouting on the lawn, hence the weather conditions are perfect for fungal infections.  We enjoyed a fantastic hot and dry summer with very consistent light levels; however, days are shortening, it’s raining (thank goodness for the farmers), its cold then warm so we should not be surprised fungal issues are beginning. 

Preventative measures are always better than cures so I would suggest making sure your tool kit for combating powdery mildew, and other potential harmful fungus, is ready to go.  Botrytis and blight may also start to appear so best to be prepared.

During late March and April whitefly has been an issue for many growers.  One grower had a huge influx from neighbouring market gardeners and another sent me pictures of TPP establishing on their company’s tomato crop.  So far, no Psyllid Yellows in that crop but this may be more visible in 4-5 weeks.  My advice, going into winter, remains to be do so with the least number of insects you possibly can to reduce spraying during the winter period.  If your control is successful now then the chance of success is much higher. Using Integrated pest management (IPM) then becomes a great option at a time of the year when outside insect populations are generally supressed.  If you don’t control it right now then you could be faced with an ongoing battle.

The light levels have dramatically dropped this week, so it is important to manage crop loading, carrying more than what the plant can tolerate will weaken plants defences further.   Twenty-four-hour temperatures need to reflect lowering light levels.  

Root health and more importantly not over irrigating is so vital.  Lowering maximum water content levels is a great way to protect the health of your root systems.  Yes, growers need to be mindful of EC increasing but there are ways to manage that.  Larger or higher tech operations will monitor, using slab sensors, but most growers still have different substrates and volumes of substrate so it is never one rule fits all.  In other words, use all of your information, from the crop registrations, to base target figures.  The growers that can optimise root health will have a far higher opportunity to maximise crop potential in my view.

As we head into late Autumn I cannot emphasise enough, and I will do this every year, that if you don’t maintain your crops health and balance you could struggle all winter.  This does not mean go vegetative, you need vigour, vegetative will only mean endless fungus nightmares, over generative will mean small fruit and weak plants susceptible to insects.  Balance is ultimately the challenge to successful outcomes.

Industry Update

Level 3 Information

 

Alert Level 3 commences Tuesday 28th April, when retail stores including takeaways and independent fruit and vegetable shops will be allowed to sell goods for contactless pickup and delivery, but customers are still not allowed to enter stores.

 

HortNZ are still working on getting independents recognised as safe and being allowed to allow customers to enter on a one-in-one-out basis like dairies.

 

Growers should continue operating as they have been under Level 4, with Covid-19 safe practises in place. This document developed by industry and MPI provides guidelines on safe practises for horticulture.  

 

We recommend that you document your Covid 19 risk management practices and keep a daily record of measures taken, even if you have five or fewer people on site.

 

All businesses operating under Level 3 need to have an appropriate Covid-19 plan in place, describing how they are providing safe work practices and a robust contact tracing system.

 

MPI general advice on what Level 3 means for primary industries is here, and more specific advice for horticulture here.

 

United fresh have added a guide for the fresh produce industry at Level 3, which can be downloaded here.

 

If you have any produce to donate, the food rescue organisations around the country are very grateful to receive it. Please email me or fill in this form.

 

Business advice and support: Free specialist support (up to $2,000) is being offered for business with 50 fulltime employees or less under the COVID-19 Advisory Fund.  This covers areas such as business continuity planning, finance and cash flow management, HR and staffing issues, etc, and will provide support over the next 12 months.

This is being managed by the Regional Business Partner Network, Employers and Manufacturers Association (EMA) and the Canterbury Chamber of Employment and Commerce.  Registration is by online application with a regional provider via RBPN, click here to access.

COVID-19 Under Level 3

Where to from here

 

It appears we are finally moving from level 4 to level 3 early next week.  I say ‘appear’ because if a spike in COVID-19 cases occurs before we move to level 3, the decision may be reversed.   Even when we move to level 3 it appears that many independent fruit and vegetable shops still won’t be allowed to reopen normally.  Alert Level 3 commences Tuesday 28th April, when retail stores including takeaways and independent fruit and vegetable shops will be allowed to sell goods for contactless pickup and delivery, but customers are still not allowed to enter stores.

What will prices be like in the next 4-5 months for produce like tomatoes and cucumbers? This is crystal ball gazing but that is the case every year.  With COVID-19 hanging around our necks it makes predicating prices even harder but if growers don’t look after crops now how will that effect production then supply and demand especially during July and August?  Market gardeners face similar challenges, decisions around whether or not to plant winter crops or dig them into the ground need to be made.  So, in my opinion, despite all the negativity and low business confidence, I think for growers whose businesses make it, there may just be a pot of gold at the end of the rainbow.   Crops that are sitting in the ground and don’t need to harvested until lockdown is lifted may flood the market, so I expect potatoes to nose dive, so please order French fries in the drive through, I will be ordering double!!

I imagine not all greenhouse growers have kept up crop maintenance and applied the necessary inputs needed in the last 4 weeks to achieve maximum production in the winter.  There is a tendency when prices crash for immediate cost cutting.  Heating the biggest casualty, followed by lowering fertiliser input and less motivation to prevent disease and pest populations establishing.  A very wise man told me on Saturday the worst thing you could do in this situation is too cut inputs/costs.  It is a very easy statement to make but I agree on the premise that unless you see no price recovery in the winter, then absolutely take the knife to your expenses but don’t complain or try to recover your crop if the tables turn.  I want to emphasise and encourage all growers to maintain normal crop measures.

 

 

Lockdown with the Kids:

I don’t know how everyone else is coping but day 30+ locked up with my four and five-year-old boys has been a strong test of my patience.  Apparently, my boys never want to go back to school/day care, they are having much more fun with Mum and I at home compared to being at school!  Running a business during the lockdown has its challenges, as so many of you are aware. For me it has meant working very late at night but I am very grateful I’ve had the opportunity to continue to work.  It is going to be a slog but these are the cards we are dealt, and as they keep telling us ‘we are all in this together’.  Thank you to all Grower2Grower customers, readers, and supporters – we would not have a business without all of you. 

Keep safe and let’s get growing. (no one was serioulsy hurt in this chainsaw chase)

Energy Options

What are our options now?

 

Before Covid-19 I’d spent a great deal of time thinking about energy, and what owners of greenhouses could do to prepare for life after coal and gas.  Now we are spinning from what the economic fallout from Covid-19 might be and what this means with regards to policies on coal and gas.  If government continues with policy plans and timelines that have already been set then what?

Currently, and for some time to come, natural gas is vitally important for the greenhouse industry in the North Island, but this will change, due to the ongoing increases in price and gas contracts becoming too complex for some growers to obtain.  The South Island is very dependent on coal, there is no natural gas pipe line in the South Island.  So, greenhouse horticulture, in the South Island, will be need to be considering their options much earlier.

So many more crops can be grown in greenhouses in NZ, even bananas. If it was economically viable, there would not be the need to import anywhere near the amount of food we currently do.  One of the biggest hurdles is the initial capital costs of some greenhouse structures and the energy requirements for growing crops that require higher heat inputs.  Currently it is much cheaper to import many foods, from across the globe, than to grow it here, but it doesn’t mean we are not able to grow it here successfully.

Below is a list of the five types of energy that may hold some sustainable solutions. 

 

1 Geothermal:

Currently there is one large NZ greenhouse company using geothermal energy to heat their structures.  The geothermal option does not include CO2 enrichment as natural gas does, so if you want artificial lighting in the future then if you are lucky enough to have geothermal you will need a CO2 enrichment option. 

 

2: Green waste land fill gas:

One company, I have written an article on see below, has been extremely smart and used the methane gas from a local green waste land fill to heat their greenhouse complex and provide (after it is scrubbed/cleaned) CO2 enrichment. 

news/post/csm–forestburg-eggplants/

 

3: Biogas or Biodigesters:

I wrote about this last year news/post/bio-digesters/

In July last year Minister Shane Jones announced New Zealand’s first food waste to renewable biogas energy in conjunction with T&G Greenhouse site close to Reperoa. 

https://tandg.global/waste-to-energy-plant-announced-by-minister-shane-jones/

 

4: Biomass – woodchip/waste product: 

Obviously this may appear to be an option but if you are not close to the source of woodchip freight costs would need to be factored, which could actually out way any positives.  Interesting to note that in the light of COVID-19 I read an article that instead of shipping logs off shore that perhaps the processing of logs may happen in NZ in the future, perhaps building a greenhouse next to a mill is worth considering?

http://enriva.com.au/projects/auckland-nz/

 

5 Solar Energy:

Has this been seriously considered?  Sundrop farms in South Australia https://www.sundropfarms.com/ has been well documented and written about in greenhouse circles.  It is an amazing achievement but what is the true capital cost?  Another article, see link below, written recently is definitely worth a read.

https://www.hortidaily.com/article/9197235/solar-energy-can-do-more-than-make-plants-grow/

http://arcon-sunmark.com/cases/%C3%B8stervang-sj%C3%A6lland-denmark

 

There are several alternate energy options available. If government or the public are serious in regards to tackling climate change, reducing carbon footprint, growing more sustainable produce in NZ, creating jobs and regional growth, then I suggest there should be even more dialogue with industry to fully investigate all possibilities.  If our greenhouse growers can reduce their energy costs not only will fresh, healthy food become even more affordable but we would be more competitive in regards to supplying food internationally.

Growers need to make profit and heating costs are a major component of total costs for many operations.  Solve this and watch this industry blossom even faster.

COVID-19 Update – prices crash

Prices crash for tomato growers but spare a thought for flower growers

 

Since I began growing, over 25 years ago, I cannot recall the market price for standard tomatoes lower than 60 cents a kilo as reported last week by several growers.  However, even though tomato prices are extremely low we should spare a thought for fresh flower growers who have been hit even harder with barely no income at all.

It has been made clear to flower growers they are not deemed an essential service so cannot supply the market at present.  Tomato growers and other vegetable growers are still able to supply the market.  Despite the price for tomatoes being extremely low the product is still selling. I hope the amount the grower is receiving is reflected in the price at the supermarket or retail outlets allowed to operate under COVID-19 Level 4 restrictions. 

If rock bottom domestic market prices for current greenhouse vegetables continue for the coming weeks/months, then this won’t just impact growers but all business that supply goods and services to growers.  We are all at the mercy of COVID-19 and the Government’s decision to move to Level 4 to minimise the spread of COVID-19, which I fully endorse. However, decisions to keep most independent fruit and vegetable stores closed will have consequences on the future existence of these smaller stores. Growers may be forced to pull out crops early.  This will have a big impact on the retail price of local fruit and vegetable’s available during the winter.  Since greenhouses produce good quantities of produce in the winter, compared to outdoor horticulture, we should be treated as ‘essential suppliers’.  To explain to readers who are non-growers, it approximately take 13-16 weeks, from germinating tomato seeds to then harvesting greenhouse tomatoes, in the winter. If crops are pulled out early there will be a shortage of supply from June to August.

The hope, for flower growers, is that there will once again be a high demand for flowers once after this pandemic passes. Postponed weddings will be rescheduled, missed birthdays will be celebrated and people will want to decorate their homes with vibrant flowers once again, those that can weather this storm will survive.  

For those thinking of diversifying into food production last week Mike Nicholls provided a fantastic article regarding Asparagus grown in protected cropping structures which is definitely food for thought.

I recently read a comment that suggested is was a privilege that vegetable growers are allowed to continue to operate during the COVID-19 lockdown.  I could not disagree more with this, it is not a privilege for growers to continue working but a necessity, fresh fruit and vegetables is imperative as it is for all primary producers to continue to work to feed us all.

Low prices equal less ATD

Try not to become side tracked

 

You could be forgiven to becoming side tracked from important plant health issues with the threat of Coronavirus gripping our thoughts.   Attention to detail (ATD) may be compromised especially with the added low returns effecting motivation.

 

Insect pressure:

The warm weather has seen a spike in whitefly and TPP reports.  Remaining vigilant is important.  I would not want is to have a battle against whitefly in winter.   Thrips are still visible on some crops.  The good news is that caterpillars have not been any wear near as rampant as last season. 

 

Rodents:

Control rodent populations.  Just this week I have trapped four juvenile rats.  My six bait stations around my house are being stripped nightly.  

news/post/rodent-numbers-high/

 

Heating:

With low prices there could be a temptation to ease heating requirements.  For crops pre-planned as long crops, consider the effects on your plants if you don’t heat adequately now.  You may be opening yourself up to a major fungal battle in the coming months.  Rain is forecast so the relative lack of fungal pressure could quickly swing.  On that note I have witnessed powdery mildew on tomato crops in the past two weeks.

 

Fertiliser Levels:

Maintaining the adequate levels of EC is critical for plant balance.  If you are tempted to reduce inputs you may face extra issues in the winter. 

 

Hygiene:

Please consider increasing your hygiene levels.  Even if you think you currently have high levels and effective precautions, no company is immune to the risk of virus entering their properties in some form.  The last thing this industry needs is to have a worker testing positive for COVID-19.  Follow government guidelines and please read the fantastic information currently provided by Horticulture NZ https://www.hortnz.co.nz/news-events-and-media/media-releases/covid-19-update-for-horticulture/

Tomato Factsheet

Tupu NZ

 

With all the country gripped by COVID-19, work and planning for the future is still a key focus for Te Puni Kōkiri — the Ministry of Māori Development.  The greenhouse tomato factsheet has recently been launched.  Due to COVID-19 the current market is struggling to adjust, but this blimp is just that and, in the future, more than ever this part of the NZ greenhouse industry will have significant importance.

Below is a brief introduction and at the bottom is the link to the recently launched Tomato fact sheet.

 

Current Industry:

There are around 125 businesses growing 120 hectares of tomatoes under cover in New Zealand. The industry generates more than $130M a year and provides about 1,000 jobs.

Almost all of our covered tomato crop is sold here in New Zealand, as whole fresh tomatoes that we buy from retailers. Exported tomatoes bring in around $10M each year, mostly from Australia, Asia, Canada and the Pacific Islands.

Future industry:

The New Zealand Institute for Economic Research (NZIER) expects the tomato industry to continue growing at about 10% per year. The issues facing the industry in the next few years are environmental. Changes to the Emissions Trading Scheme (ETS) and rules around nutrient discharge and run-off will have an impact on growers.

COVID-19 (Hygiene)

Hygiene is greenhouse growers number one priority

 

Even before the world was alerted to Coronavirus the tomato world, especially in Europe, has been battling its own war on a plant virus, the Tomato Brown Rugose Fruit Virus (ToBRFV for short).  New Zealand growers are well aware of the risks and the threat to our industry if ToBRFV were to evade our border controls and make it on to our shores. 

While ToBRFV obviously pales in comparison to the implications of Coronavirus, it highlights the need for much stricter hygiene controls for everything!  Within the greenhouse industry all stakeholders, from the growers, suppliers, wholesalers, retailers, transport companies and advisors, have a duty of care to do everything to assure the public that extremely high hygiene protocols have been used throughout the entire food chain.  When the consumer picks up the product at the supermarket, they need to be confident they are purchasing products that have complied 100% with quality assurance programmes.  As an industry we already have excellent compliance programmes that growers and packhouses strictly adhere to.  The only thing that could let the system down is complacency, so my advice is to keep on our toes (which should not be hard to do at this point in time) and as a collective, let’s discuss if there is even more, we could be doing. 

Last week I was asked to wear full protective gear when visiting one of my customers, to advise on their crop, this included wearing a face mask. I had everything ready to put on as soon as I arrived in the grower’s carpark.  It was then removed into a plastic bag ready for disposal when leaving the property.  I don’t believe the request to wear the face mask was over the top but demonstrates the seriousness that growers are taking when anyone enters into their growing or packing areas.

Disinfecting and preventing the spread of COVID-19 is something I take seriously.  I advise all growers to have ample stocks of disinfection products and protective clothing.  Below is a list of some basic precautions I would exercise:

  1. Hand Sanitizers applied at every building entry/exit point
  2. Footbaths at doors (regularly topped up)
  3. Sanitisers to clean all greenhouse equipment
  4. Regular changing of gloves, masks, cover shoes
  5. Regular dipping/cleaning of pruning equipment
  6. Alternate staff breaks to limit close contact (see HortNZ link below)
  7. Regular washing of hands before and after exiting greenhouse each time.
  8. Work in your own assigned area if possible

Some commercial greenhouse products that are very good for hygiene and sanitising are:

  1. HuwaSan (Hydrogen Peroxide based disinfectant)
  2. Virkon S
  3. Sodium Hperchlorite

Even before Saturdays state of the nation address from New Zealand’s Prime Minister Jacinda Ardern, Edward Lee had started increased hygiene measures when handling the produce.

 As of Monday the 23rd MPI have released new rules for growers to remain open.  Please click on the link below and follow all of the recommendations from HortNZ. https://www.hortnz.co.nz/news-events-and-media/media-releases/covid-19-update-for-horticulture/

 

Everyone that is a visitor to a greenhouse must realise they pose a risk to transferring diseases.  Covering up is the only option.

Keep safe!
