Harvesting my potatoes last year I noticed alot of grub damage. Can it be used once in April about 2-3 weeks before planted. Then potatoes won't be harvested until August/September? Or would they be no longer edible.
Spectracide Triazicide Once & Done Insect Killer Concentrate is not labeled to be used around edibles and would not be recommended. You will not be able to harvest until the next growing season if you do use it. If you know you are dealing with Japanese Beetle grubs you can use Milky Spore in the area.
