Can Merit Granules be used as a systemic treatment for trees?
Bayer sells a product, "12 Month Tree and Shrub Protect and Feed" which contains 1.1% Imidacloprid plus some fertilizer. Can I substitute Merit granules or ImiGold for the same systemic tree treatment if I adjust the dose to account for the lower percentage of Imidacloprid?
Merit Granules and Imigold Granules can be used for trees but is only labeled to treat white grubs when used for tree applications. Merit 75 WSP or the less expensive Adonis 2F is most often chosen to use for systemic root drenches on trees and shrubs.
