We apologize, we do not sell Xytect. Criterion WSP is the most popular choice for emerald ash borers. You need 1.4 level teaspoons per inch of diameter. This is the highest rate and should be used for all boring insects. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per inch of tree diameter but you may use 1 quart -1 gallon of water per inch as well. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested. Since sandy soils can accept more water, using the higher volume of water is preferred. Treatments should begin in May or June and should be done every year to protect trees from the EAB.
