Insect Control on Cabbage with New Pesticide Compounds

摘要

A number of different chemicals have been evaluated for control of cabbage loopers and other lepidopterous pests of cole crops over the past several years. These materials are usually formulated as dusts or emulsifiable concentrates but some have been prepared as wettable powders or granular formulations. Some are more effective against one species of insect than another. Only a very few of the prospective pesticides passed all the required testing and became available commercially.
