Abstract:
Under its most ambitious effort, Total Seed Treatment Campaign 2007, the Indian government offers recommendations for seed treatment for a variety of crops. Three insecticides, imidacloprid (600 FS), fipronil (5 FS), and chlorpyriphos (20 EC) (each at three dosages), were evaluated in vitro (lab tests) to see whether test doses for the maize crop had any harmful effects. Statistics showed that seedling lengths were decreased after treatment with chlorpyriphos (P 0.05). All three imidacloprid test dosages (1.5 ml, 3 ml, and 5 ml per kg seed) increased overall length but statistically were comparable to the control. A substantial difference from all other treatments was seen in the case of the fipronil test-dose (7 ml/kg seed), which led to an increase in overall seedling length. Chlorpyriphos dosages all resulted in a sharp reduction in seedling length, indicating a negative effect on seedlings. Imidacloprid and fipronil seed treatments were shown to be safer and recommended for maize crops in the study's final analysis. Chlorpyriphos is not suggested for treating maize seeds, though. These seed-treatment rates might be tested for additional field validation in order to reduce pest insects that are of concern.
