Have I destroyed my crop with bugclear? :-(

[LINZ_2016]

Good Morning

My strawberries had vine weevil larva and I was told to treat with Bugclear vine weevil treatment which I did.

I have now been told I should not have and to bin my whole crop (25 plants).

Please can someone advise me? They are june bearing so wont fruit for 3m or so.

Thank you

Welcome to the forum!

I personally wouldn't use that insecticide on anything, and certainly not food. The compounds basically kill everything, including beneficial insects, and will probably still be around when the strawberries ripen, as they tout it as "lasting 6 months".

I’m not familiar with the product, but searching for msds came up with these ingredients.

Acetamiprid
Ethanol
Aqueous dipropylene glycol solution of approx. 20% 1,2-benzisothiazolin-3-one

Glycerol (Glycerin) 1,2,3-Propanetriol

…I also found an older thread in our archives that may be related/informative —
Why cant bug clear ultra be used on everything?

… I am sorry to say, the soil in the bed might also not be safe for a while. But depending on where you live, you may still have chance to get another bundle of plants and start them in a different location or in containers. My own shipment of new bareroot strawberry plants to be planted are not arriving until next week….

Thank you all

They are in a tiered wooden planter so I am in the process of replacing all soil with fresh and replacing the liner

I hope that will be enough.

Gutted isnt the word!

You should always read the label. The label is the law. If the plant is not listed, it means it has not been tested so there have been no studites to determine safety, phytoxicity, or residual chemicals which determines days to harvest.

If you have wooden planters, it could seep into the planter wood as well. If you can use that planter for something else it would be better.

Usually companies will either have a phone or contact website where you can ask about how long the product might remain in the soil or in porous surfaces like wood.

Bifrenthrin, a synthetic pyrethroid, if combined with an oil can last almost a year.

Pyrethrins, naturally extracted from some chrysanthemums, and not combined with oils is allowed for organic gardens, although it still remains highly toxic to bees.
