Product Q&A

Answer:

We would recommend to apply Merit 2F Insecticide as a systemic around the base of the trees. Most people use a 5 gallon bucket or a large watering can to apply Merit 2F as a soil drench. You will need 0.1 to 0.2 fl. oz. (3 to 6 mL) of Merit per inch of trunk diameter for trees. 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 trunk diameter but you may use 1 quart -1 gallon of water per inch of trunk diameter for trees 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. After the soil drench has been applied you should water it in with at east 1/2 inch of water. Note: Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved. Insecticides applied to the soil are taken up by the roots and translocated throughout the tree or shrub. Root/soil drenches offer the advantage of requiring no special equipment to apply (other than a bucket or watering can). However, surface layers of organic matter, such as mulch or leaf litter, can bind the insecticide and reduce uptake. Before applying drenches, it is important to remove or pull back any mulch or dead leaves so the insecticide solution is poured directly on the mineral soil. It is also important to keep the soil around the tree or shrub moist for the next 7-10 days after applications to encourage uptake. This may take some time. In the meantime, we you could apply Talstar as a foliar spray.
