Can Hi-Yield Vegetable & Ornamental Insect Control Granules be used to control onion maggots?
Answer:
Hi-Yield Vegetable & Ornamental Insect Control Granules is not labeled for root vegetables and we would not recommend it for onion maggots.
Pyganic Gardening would be a product you could use though it is more of a contact kill and leaves no residual
Malathion 57% is another option.
