Bacillus thuringiensis var. Biobit and Dipel are highly selective insecticides. Larvae must eat deposits of the insecticide to be affected. Close scouting with early attention to infestation is recommended. Apply when larvae are young.
Thorough coverage is needed to provide a uniform deposit at the site of larval feeding.
Larvae stop feeding after eating a lethal dose of the insecticide and will die within several days. Consult the label for information concerning active ingredient, application, and tank-mix compatibility. Do not apply within 18 days of harvest if a spreader sticker is used. Do not use in more than three applications per season. Do not enter treated area within 24 hours unless proper protective clothing is worn.
