Introduction

Thrips are a common pest in cotton cultivation, posing significant threats to crop yield and quality. Effective management of thrips is essential for maintaining healthy cotton plants and ensuring optimal production. Thrips infestations can cause reduced photosynthesis, stunted plant growth, and lower fiber quality, significantly impacting the economic returns for cotton farmers. Proactive and timely management practices are crucial for mitigating thrips damage and ensuring the long-term health and productivity of cotton crops.

Symptoms

Thrips feeding on cotton leaves causes them to develop a silvery or bronzed appearance due to cell damage and their excrement. Young plants may show twisted or stunted growth with malformed leaves and buds. This feeding can also scar leaves, making them look crinkled or puckered. Infested buds and flowers may not open properly, reducing flowering and boll development. Additionally, the presence of black specks (thrips excrement) on the undersides of leaves indicates thrips activity.

Preventive measures

Crop rotation, planting resistant varieties, and maintaining field sanitation is essential for effective thrips control. Encouraging natural predators and using beneficial nematodes support biological control, while selective insecticides and seed treatments offer chemical solutions. Proactive and timely management practices are crucial for mitigating thrips damage and ensuring the long-term health and productivity of cotton crops.
