Is Merit 75 WSP safe to use as a soil drench for Citrus?
Can I use this on Citrus for psyllid control? Should I harvest fruit first? How long will this persist in the plant?
Merit 75 WSP cannot be used on a citrus tree. The product can persist for about 1 year after the application inside the tree. There is another product called Imidapro 4SC which is labeled for use on citrus trees and it contains the same active ingredient as Merit just in a different formulation.
