Evaluation of the Effectiveness of New Phytosanitary Protection Programs in Cotton Crops Adapted to Jassids

In recent years, jassids have become a problem for cotton and the current control program this pest seems ineffective. This study was therefore initiated with objective of evaluating effectiveness three new phytosanitary protection programs against jassids. Trials were conducted at Nambingué observation post. The designs Fisher blocks 5 objects 4 replications. Each elemental plot had length 10 m width covering lines, 8 which treated. spacing between rows 0.8 m. distance patches on line 0.4 2 Six insecticide treatments carried out. Treatments started 45th day after emergence, 14-day intervals. These programs, differ according to composition positioning active substances, tested during two years in fisher block design four repetitions. Two labelled B C, an efficacy threshold greater than 80%. Program characterized by spiromesifen or chlorantraniliprole T1 T2, cypermethrin + abamectin T2 T3 spinetoram sulfoxaflor T5 T6 respectively. And C Deltamethrin chlorpyrifos ethyl T4 dinotefuran 14% alphacypermethrin 22% They both contributed significant reduction jassid outbreaks experimentation. Programs can be used as alternative extension manage resistance.
