The infestation causes premature leaf drop through most of the summer months. Since the tree is rather large I would assume that a systemic insecticide is the best approach. Do you believe that the Systemic Insect Drench would help to resolve the problem. I am afraid it might be too late to save the foiliage this year since the galls are already begining to appear on some of the leaves. Any assistace you can provide would be appreciated. Thanks
A systemic is definitely what you would need as foliar sprays only help when they are in certain stages on the hackberry tree. The sytemic product would normally take a couple of weeks to translocate all the way through the tree so a foliar spray may help in the mean time until the product works its way through the center. The Fertilome Systemic Drench would be a great option and will typically last for a full year in the tree. We highly suggest using it again before symptoms start to appear to prevent your trees damage the next year.
