We had similar to happen in Alabama when the local county start spraying the roadsides. They didn't account for the runoff and did a lot damage to river's system. Plants died and fish caught out the rivers had large sores along some dying. I even was fishing one time when they across the river bridge spraying. I immediately had to take a dip upstream to wash off the spray. I went to county commissioner about. At first he said "We don't spray over water" but I said they did do it on that particular river. He since corrected the problem by making sure his sprayers know better. Of course he is now retired and I have moved away so it is someone else's responsibility now.I've become a victim!! I planted sweet corn 6 rows about 2 weeks ago on the lower side of the cell tower site we have on our property. Have planted various crops there for years. I sprayed it with my normal weed control spray. It started to emerge nicely. About a week ago we had a torrential downpour. I went out the next morning and saw that the rain had washed down through the outside edge of the last row of corn. Monday morning I noticed some of the corn turning brown. I was kind of second guessing myself that I might of had some spray overlap (overdosed). Yesterday I was walking by the cell tower and noticed that the weeds inside of the tower fence were brown. Apparently the company that does property maintenance for the cell co. had been there. I found the tag they attach to the fence to prove they had been there. It's dated and has there name on it. They had sprayed a few days before the rain and apparently the residue was washed off the stones and weeds and ran into my corn patch. I contacted the company and got the list/label's of the herbicides they used. I really didn't lose much corn but I now have to be concerned about the residual effects of when and what I can plant in that area in the next year. This was kind of a freak occurrence due to the timing of when they sprayed and when we had such a heavy rain. I'm going to be calling the cell tower Co to request that only certain herbicides be used to control weeds in the future.
