Neonicotinoid Study Published

[Don Mac 318]

The first New Zealand soil residue study on neonicotinoid insecticides has just been published.

Note it is only the 4th study published on pesticide residues in the environment ever published in good old clean green NZ.

The cynic in me says "we really do care about the environment!"

 

Chris Pook and Iana Gritcan have published their work in the Journal of Environmental of Pollution in their December 2019 Publication.

The abstract s here;   https://www.sciencedirect.com/science/article/pii/S0269749119301381?via%3Dihub

 Validation and application of a modified QuEChERS method for extracting neonicotinoid residues from New Zealand maize field soil reveals their persistence at nominally hazardous concentrations

 

The study has been published by Stuff https://www.stuff.co.nz/business/farming/117759904/study-shows-chemicals-could-cause-beehive-losses

This morning Dr Pook also featured on Breakfast. Available on TVNZ On demand

 

The Study samples were gathered from sites in the Bay of Plenty, Waikato and Gisborne, where beekeepers have reported hive losses over many years, especially immediately after maize harvest.

Are you one of those beekeepers? We need these reports guys - no reports then there is no action!

 

This study owes a lot to the challenge I got from Neil Mossop of Mossops Honey who told me of their many years of experience of loosing hives, so much they do not place hives there anymore in these areas after maize harvest .

His challenge was to find out what is going wrong. Well we cannot confirm causation at this stage, but it is very apparent that our Ag practices are leaving significant neonicotinoid residues in the soil and environment.

 

Here are the main key points I have got from this study.

1. Why is NZ not monitoring pesticide use? How much is used, where it is used and what chemistry is used? Examples of where this is used include Netherlands, California.
2. Lack of monitoring and research into all pesticide residues in NZ This is the 4th paper published to date. We do not have a clue of what is happening in our environment. There is no testing of new pesticides on effects on native vertebrates. There is no ongoing monitoring and measuring of soil residues and waterway contamination.
3. How are we using our pesticides? Seed treatments are used as prophylactic treatments, not specific targeted treatments. Are we apply to much with respect to seed treatments?
4. Poor enforcement. The EPA has set Environmental Exposure Limits as per the HSNO Act. but has never measured the environment to see if limits are being exceeded. There is one exception 1080. The Minister for the Environment obviously does not care.  
5. Honey bees gather what is in the environment when they collect nectar, propolis, pollen and water; the 4 main inputs to a hive. We know they are collecting; pthathlates (detected in propolis) fungicides in wax, glyphosate in honey etc.  And we have no research money as an industry to continue this work.
6. Note the study has not yet linked the soil residues to the death of the hive, so we cannot state it is the causative factor or claim causation. The study has correlation because we went to known bee dead areas to obtain the soil samples.

 
 The study was funded by AUT. No beekeepers money was used to fund it - so we are all freeloaders. So how do we fund continuing research that could determine causation?

Biggest problem in trying to delete the coating of the seeds is Monsanto (now Bayer) own shares in all the major seed producers, and they are not about to give up that large section of their sales anytime soon.

unless being forced to. which they should

[Anne 44]

And if the insecticides, herbicides and fungacides are removed for the bees health what are the options for pretty much the guaranteed food supply for you and me . I used to be a market gardener now have a few bees and mixed crop farm. I see crops get blown over all the time if bugs n diseases arent dealt to. So should the $$ go to finding a alternative to the chemicals in main stream use or into the blame game. I see a lot of belts getting let off a hole or 2  and that comes from the luxury of plenty of food so becareful not to shoot the hand that feeds you and work with it instead. Im all for alternative chemicals that benefit all but like all I cannot sacrafice my income either.

I know this can be a contentious issue, but having been in the organic sector for many years, my understanding is that pests and diseases diminish when the soil is treated properly, with composts and natural fertilisers that put into the soil what the crops being planted need. This creates healthy soil, healthy plants far less susceptible to pests and diseases, without the need for chemicals.
Yes it is more time intensive, but it should be seen as one of the solutions, and not just a fad as so many people think.
You don't need truckloads of chemicals to grow decent nutritious food, and the chemicals are just destroying what should be vital healthy soil. There are very few soil fauna in chemical laden soil. Such a shame.

[john berry 5,636]

every time we get research into Neonics we seem to get the same answer that they may be causing problems. My own conclusions from doing pumpkin pollination are the same. There wasn't enough damage to the hives to prove conclusively to me that it was causing damage but those hives had higher losses and were below par for three years afterwards.

[nab 86]

it comes down to what produces more food.  wind pollination vs bee pollination. 

 

the answer is in the continued use of insecticides.   

 

also air-seeders are one of the biggest spreaders of the neo-nik dust

 Until it can compete financially with conventional cropping nothing will change.

Again, the big shame is that the word "conventional" is used for chemical laden food production, which is wrong. Organic production has been going on for millenia, and is conventional. Chemical production is just that, chemical, and really is the sop out lazy way to grow proper food.

 

Organic production can be far more financially viable, but it is the fact it is more labour intensive that puts people off. As I said, chemical production, which destroys so much of the environment, and so many necessary insects, is just lazy farming... If I upset anyone by saying this, I am not sorry, its just a fact.

I agree with what you are saying.

its called conventional because food was always produced to feed people. organics use to work fine 100 years ago. the use of chemicals to control pest and diseases to increase yield only come with the increase of human population.    the big question is who gets to choose what half of the world starves.

Food would have to become more expensive .

People may have spent a bigger percentage of their income on food once than they do now .

Food has been kept artificially cheap by fossil fuels and pollitical necessity

just lazy farming

I was pondering how lazy I was being this morning , tuning up a little bit of black berry on the road side that persists every year . It used to be a jungle many years ago , climbing fences and trapping wildlife amongst its thorns .

 

I wondered if I wasn’t being lazy , and left it to grow , how many townies would notice it and organise a working bee to clean it up , along with all the KFC rubbish that gets hiffed out the window , then I realised they wouldn’t.

 

My mind wandered , then , onto organic beef . I could produce it , but it would cost . I’d need to pay a full time team to weed the roadside , and the drains .

 

Anyone free on the weekend ?

The dairy farmers who joined the Biological Farming Group - where they decrease their urea over five years for example, and reduce number of stock slightly find they are then far more profitable - for example, vet fees reduce dramatically. Bit like beekeeping right now, if EVERYONE reduced their hive numbers by 30%, they would need less of everything, including labour, and would be a great deal more profitable, with healthier bees. Unfortunately hell ain't about to freeze over.

I thought blackberry was a good nectar source for bees that produced a surplus .

you'd probably get someone complaining about pest plants/weeds, plenty of people throwing kfc rubbish out the window, and nobody helping...

It doesn’t get mature enough to flower , although it does on a block over from me . The birds move the seeds around

Newshub (TV 3) featured Dr Chris Pook and Neil Mossop in a discussion on this very topic.

https://www.newshub.co.nz/home/rural/2019/12/maize-crop-chemicals-blamed-for-mass-north-island-bee-deaths.html

Since the publication of Dr Chris Pook and Iran Gitan's paper there has been another paper recently published in France which shows residues of imidacloprid in Canola feilds.
Wintermandel's study showed that imidacloprid residues was in the soil 5 years after they stopped using it at levels that showing a mortality risk to bees 5 years after last being used.     This French paper backs up the results of the NZ Study.

Quote

A more likely mechanism of large-scale imidacloprid spread is
transport by water in leachate, run-off or contaminated irrigation
water (Bradford et al., 2018; Huseth and Groves, 2014;
Kurwadkar et al., 2014), which neonicotinoids are prone to as they
have to be water-soluble to be systemic (Bonmatin et al., 2015;
Giorio et al., 2017). This is supported by our finding that imidacloprid
prevalence and concentration increased with rainfall in the
days before sampling and was higher on red soil (i.e. unsaturated
brunisol on ferralitic clay) than on calcareous soil.

and what do bees need, water. if there is no plants for them to get dew or nectar off where do bees drink?

didn't one of the gizzy flats test show lethal amounts in the water on the edge of the fields ??

[Bron 2,780]

I’m not surprised at all. We no longer have bees on the flats. I’d be curious as to what they use on the brassicas as well.

 

 The big question is what happens next?
