Borers killed crabapple - best insecticide to treat soil to prevent again
Borers killed my prairie fire crabapple, arborist said to remove and great soil with Di-syston granules before planting new one. Is this the best insecticide or can you suggest how to prevent this if I plant a new tree?
Dominion would be a great product to treat the soil. Once the tree is planted you can treat it with talstar P.
