aminopyralid tomato curl

Asked June 4, 2019, 11:36 AM EDT

I got well aged manure from a horse farm and worked it well into the soil in the spring before planting. About 3 front loader scoops for a 1000 sq foot garden. It really did not seem like a whole lot. All of my tomatoes have the tomato curl. This was new to me.... never heard of this before. The pictures I see online in many articles including yours are exactly what my tomatoes look like. There is no doubt in my mind it is aminopyralid. My question is how does affect the harvests from the other plants that do not show any signs of toxicity? Are they contaminated and not good for human consumption? We try to go as close to organic as possible. How will this affect next year?!

Hi
I can't confirm your situation is aminopyralid contamination, but if it is, I have attached a couple of reliable information sheets/sites. You might want to investigate what the regulations on the use of the chemical in Virginia as it seems there are a number of varying state regulations. It is persistent in soil, so you may see affects for 2 or 3 years; however, there seems to be no discussion of danger to human consumption and many kinds of plants are not affected. Here are the sites information: https://extension.umd.edu/learn/gardener-alert-beware-herbicide-contaminated-compost-and-manure; https://www.manurematters.co.uk/faqs.html; https://www3.epa.gov/pesticides/chem_search/reg_actions/registration/fs_PC-005100_10-Aug-05.pdf.
