Cotton Thrips Control Measures

Integrated Pest Management (IPM) methods offer a comprehensive approach to effectively manage and control cotton thrips. This multifaceted strategy encompasses a range of techniques, including cultural, mechanical, biological and chemical measures, providing a holistic solution for thrips control in cotton cultivation. 

Cotton Thrips Cultural Measures

• Remove weeds and other debris in and around cotton fields regularly to reduce their population. 
• Avoid using excessive amounts of nitrogen fertilizers, as this can lead to succulent growth which encourages thrips population. 
• Maintain healthy plant growth by providing proper irrigation and adequate nutrients, which helps to reduce the impact of thrips on cotton crops. 

Mechanical Measures

• Remove and destroy the infested plant parts. 
• Tapas Yellow Sticky Trap can be used to control thrips in cotton field. Install 6-8 traps per acre for effective management.
