The occurrence of pests and diseases in cotton bolls is a major concern for farmers, especially during the growing season. The main pests affecting cotton include the fourth generation of cotton bollworms, as well as cotton blind mites, small cotton worms, and leaf mites. The previous rainfall was relatively high, which led to increased moisture levels in the fields. This condition was not favorable for the third generation of cotton bollworms, as excessive rain can reduce their population. However, the average temperature in mid to late August remained close to normal, while precipitation levels were higher than usual. These meteorological conditions created a favorable environment for the development of the fourth generation of cotton bollworms.
In terms of prevention and control methods, there are several effective strategies that farmers can implement. First, agricultural practices play a crucial role. Field management, such as pruning cotton plants and removing unproductive flower buds, helps reduce pest pressure. Additionally, manually wiping eggs from the plants can significantly lower the need for chemical interventions.
Second, chemical control is an essential part of managing these pests. Farmers can use 5% hexaflumuron emulsifiable concentrate diluted at 1000 times or 1% carbaryl salt solution diluted at 1000 times. Other options include pyrethroid or organophosphate-based pesticides, applied at a dilution rate of 1000 to 1500 times. To further support plant health and prevent premature aging, it is recommended to combine pesticide applications with foliar fertilizers such as potassium dihydrogen phosphate. This integrated approach ensures both effective pest control and improved crop resilience.
