Study non-ionic detergent and synthetic pesticides to control in main sucking pest of cotton

Sucking cotton pests that break out at a certain time during the cotton season have always played a key role in reducing yield and fiber quality. Therefore, efforts have always been made to develop effective chemical control methods to control different species of sucking pests with only one spray

In this study, the efficacy of the treatments was investigated: 1- non-ionic soap solution (2000 ppm); 2- spirotetramat; 3- imidacloprid; 4- Eforia® (thiamethoxam + lambda-cyhalothrin); 5- mixture of soap (1%) and spirotetramat; 6-Mixture of soap (1%) and imidacloprid; 7- Eforia® and non-ionic soap (1%); 8- Buprofezin insecticide (Applaud ®); 9- Buprofezin with non-ionic soap (1%); 10- Dinotefuran (Starkle ®) and control, against some important cotton aphid pests including Aphis gossypii, Bemisia tabaci and Creontiades pallidus were evaluated in 2018 with three replicates in a randomized complete block design by reaching the threshold and sampling before, 3, 7, 14 and 21 days after spraying under field conditions in Mazandaran and Golestan provinces. Efficiency of treatments was calculated based on percent mortality modified by the Henderson-Tilton formula.

The results of mortality due to initial effects (3 days) and residues (21 days) in both provinces showed that the efficacy of the two insecticides imidacloprid and spirotetramat with nonionic soap against Aphis gossypii and Creontiades pallidus. Buprofezin proved to be a suitable treatment for whitefly control

Non-ionic soaps can be recommended for use with insecticides. On the other hand, non-ionic soap eliminates not only sucking pests but also honeydew to prevent sooty mold and improve cleanliness.
