Quality Enhancement of Soybean Seed Coated with Nano-formulated Thiamethoxam and its Retention Study

The use of insecticides for seed treatment is one of the most effective modern pest control practices. Therefore, the influence of these products on the physiological quality of treated seeds should be known. This study aimed to evaluate the physiological quality of thiamethoxam treated soybean seeds stored for three different periods. Seed coating was performed with 12 controlled release (CR) formulations of thiamethoxam based on amphiphilic polymers along with commercial formulation and control. The percent thiamethoxam recovery ranged from 86.1–93.2% from different CR formulation seed coats. Better thiamethoxam retention was observed on soybean seed coats treated with CR formulations. Different seed quality parameters viz., seed germination, seed vigour, seed moisture and seed storability was evaluated during the six month experimentation. The seeds coated with different nano-formulations had better seed quality over control and commercial formulation.
