Efficacy of ready-mix insecticides against sucking pests of Bt cotton
Research Type
Non Project Trials
Experiment Background
Cotton is most important commercial crop known as “King of natural fiber” and world over commonly referred as “White gold” which belongs to family Malvaceae and genus Gossypium. Bt cotton hybrids and high yielding varieties are more susceptible to insect pests like pink bollworm and sucking pests. Cotton crop is subjected to damage by 162 species right from emergence till the final picking (Manjunath, 2004). Insect pests are reported to cause damage to cotton crop at different growth stages and difficult to control. The use of insecticides has played a major role in increasing cotton productivity for the last three decades. However, the indiscriminate and injudicious use of insecticides has led to many problems including the resurgence of sucking insect pests, development of insecticidal resistance in some insects and residues in food stuff, consequence is that the chemical control has become less effective. Application of mixed formulations has been reported to be an effective approach to delay the development of resistance in insects, to avoid the resurgence problem and to achieve effective control over different insect pests in different crop windows attacking cotton simultaneously. Therefore, an attempt needs to study the efficacy of ready-mix insecticides against major sucking pests of cotton. Hence the experiment is proposed for the same.
