Sarah from Charlotte, Nc writes,
How frequently should Adonis 2F be applied for whitefly/aphid infestation on large ligustrums?
I used entire 27 1/2 oz on 36 ligustrums that are about 10 feet tall. Leaves have sooty mold and eggs are on undersides of leaves. Hoping systemic will be effective before eggs hatch in March. How frequently should I apply the insecticide? And, did I use enough?
You will need to apply Adonis two times per year for whitefly. You may also need to use a foliage spray such as Talstar P to get control of the whitefly as the Adonis is tranlocated through the plant (it can take about month to translocate through the plant).
