Got a customer with a few fruit trees. Sprayed 'em on 7/24 with Sevin, for Japanese beetles. Two weeks later I was back mowing and checked on the trees. All was well except for one tree that was buzzing with yellow jackets. And the tree was leaning to one side. Huh? I grabbed the trunk and was able to wobble it from side to side. I could have easily pushed it over. This is a tree with a 5" diameter trunk. Fruit looked normal (other than a little insect-eaten), leaves looked normal. Customer was on vacation so I sent an email letting them know of the problem. Now, two weeks after that, the tree is clearly dying. I don't see any hope for it. The leaves look a little wilted but still green. The fruit is all but gone, eaten by insects. I want to get in close to check the roots and take a soil sample, but I can't get close because of the hundreds of wasps that are there snacking. I was thinking of spraying it with more Sevin, then going back the next day. Would that do the job? So, 2 questions: What the he!! could do this to a tree? and What's the best way to deal with the yellow jackets? At this point I can wait for a couple days for something to work.
