Abstract:
The protection of developing seedlings from insects, diseases, and pests begins with seed treatment. Under most ambitious effort, Total Seed Treatment Campaign 2007, the Indian government offers recommendations for seed treatment for a variety of crops. To confirm the harmful effects of test dosages for the groundnut crop, laboratory studies using three insecticides—imidacloprid (600 FS), fipronil (5FS), and chlorpyriphos (20 EC)—were conducted using the in between paper technique. In our study, the germination percentage for all test-insecticide dosages was more than 70% (range: 74.13% for chlorpyriphos at 25 ml/kg to 96% for imidacloprid at 5 ml/kg). However, with greater dosages of chlorpyriphos and fipronil, additional seedling characteristics (total seedling length and vigour indices) were impacted (P0.05). Imidacloprid did not negatively affect seedling development at any of the three test dosages, but rather may have a phytotonic impact. In short, it was discovered that seed treatment with imidacloprid at levels of 3–7, fipronil at 5, and chlorpyriphos at 6 ml/kg seeds was safer and advised for groundnut crops. These rates of seed-treatment might be tested for additional validation under field in order to reduce pest insects that are of concern.
