Abstract
Insecticide efficacy against diamondback moth, Plutella xylostella (L.), imported cabbageworm, Pieris rapae (L.), and cabbage looper, Trichoplusia ni (Hübner), on cabbage was investigated, using a threshold of 0.5 total larva per plant as a basis for comparison. Materials were evaluated on the basis of control achieved, frequency of application necessary for control, and crop marketability. Results indicate that evaluating materials on this basis is useful in determining how they may best be incorporated in a scouting decision-making system.This publication has 2 references indexed in Scilit:
