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 (600FS), fipronil (5FS), and chlorpyriphos (20EC) (each at three dosages), were evaluated in vitro (lab tests) to determine whether test doses for the soybean crop had any harmful effects. Germination rates often above 80% for all treatments, including the control, much beyond the ISTA (2008) standard. However, greater chlorpyriphos dosages had a negative impact on several seedling parameters, including total seedling length and vigor indices I and II, which were measured at 26.23, 2214.4, and 36.29 (for a 6 ml/kg dose) and 20.5, 1710, and 25.86 (for an 8 ml/kg dose) correspondingly. Untreated seedlings with the equivalent control values of 35.9 cm, 3144.88 cm, and 54.86 cm are significantly higher and differ statistically (P 0.05). In the end, it was determined that seed treatment with imidacloprid at 4-6, fipronil at 3-5, and chlorpyriphos at 4 ml/kg seeds was safer and advised for soy crop. The rate of these seed treatments might be tested for additional validation under field in order to reduce pest insects that are of concern.
