Resumo

Chemical Control of the Diamondback Moth Pluteila xylostella (L.) in CabbageInsecticide efficiency was evaluated to control the diamoridback moth, Pluteila xylostella (L.) in cabbage.The experiment was carried out in Gravati, PE, Brazil during June to September 1991.A randomized biock design was used to compare nine treatments: Bacilius thuringiensis -Dipel 32 PM (0.06%); prothiophos -Tokuthion 500 CE (0.1%); perimifos-metilico -Actellic 500 CE (0.12%); cartap -Thiobel 500 PS (0.12%); metamidofos -Tamaron BR (0. 1%); lambdacyhalothrin -Karate 50 CE (0.05%); cyfluthrin -Baytroid CE (0.02%); beta-cyflutrin -Bulidock 125 SC (0.004)% and control, each with 4 replicates.Eight insecticide applications were made weekly starting 30 days after transplant until the week before harvesting.The efficiency of products was evaluated weekly, beginning at the head formation stage, until harvest, when the percentage of marketable cabbage was estimated.Results indicated Dipel as the most efficient treatment, followed by Tokuthion, Thiobel, Actellic and Tamaron.Karate, Baytroid and Bulidock were not efficient.
