| Abstract: | Field applications of commercially produced Bacillus thuringiensis var. thuringiensis for control of the diamondback moth larvae, Plutella xylostella; the imported cabbageworm, Pieris rapae; and the cabbage looper, Trichoplusia ni in the early and mid-1960s did not provide sufficient control of these insects to allow a marketable crop of cabbage under Wisconsin conditions. Replicated field plot studies conducted in 1969 and 1970 utilizing commercially produced B. thuringiensis var. thuringiensis and commercially produced products from the HD-1 isolate of B. thuringiensis var. alesti indicated that the δ-endotoxin produced by these biological agents can provide adequate control of the cabbage caterpillar complex when applied on a regular weekly basis throughout the growing season. |
