Comparative Experiment on the Efficacy of Different Pesticides in Controlling Tuta absoluta
In order to screen out effective,low-toxicity and low-residue biological agents for the control of Tuta absoluta,three bio-logical agents,namely 6%ethyl polycidin suspension(Iverucidin),31%Avicidin suspension and 20%chlorfenamide suspension were selected to conduct drug efficacy tests in Aksu City in 2022.The results showed that the three biological agents had certain con-trol and inhibition effects on the larvae of Tuta absoluta.From the point of view of control effect,20%chlorobenzamide suspension had the highest quick-acting,persistent and control effect,and the control effect was 90.32%after 14 days.It was followed by 6%ethyl polycidin suspension(Alucidin),which had good durability at 14 days after administration,and the control effect was 81.49%.In the actual production,the use of 20%chlorobenzamide suspension and 6%ethyl polycidin suspension can achieve better control effect,and slow down the resistance of Tuta absoluta.
