Abstract:
Bioagents are beneficial for plant and soil health and are proved to be compatible with different weedicides till the threshold level is achieved. The effect of compatibility of P. fluorescens (strain 28) with four weedicides viz., Pendimethalin, Sulfosulfuron, 2, 4-D and Isoproturon was observed. Each weedicide was evaluated at different concentrations viz., 10ppm, 15ppm, 20ppm and 25ppm and their inhibition on growth of Pseudomonas fluorescens was recorded. It was found that the four weedicides i.e. Pendimethalin and 2, 4-D were compatible at any concentration tested against Pseudomonas fluorescens than other weedicides i.e. Isoproturon and Sulfosulfuron. Sulfosulfuron was comparatively more toxic than Isoproturon, with respect to the level of percent inhibition of Pseudomonas fluorescens at 10ppm, 15ppm, 20ppm and 25ppm concentration respectively after 96 hours. The present study was therefore undertaken to evaluate the threshold level of different weedicides at suitable concentrations for effective growth of bioagents.
