Compatibility of carbosulfan and Azotobacter chroococcum as seed treatment for management of Heterodera avenae in Wheat

Results revealed that all the treatments reduced cyst population over control but this reduction was significant only in soil application of carbofuran 3G (1.5 kg a.i./ha) and seed treatment with carbosulfan 25 ST (2% a.i. w/w). Seed treatment with carbosulfan and soil application of carbofuran proved equally effective in reducing cyst population. Azotobacter chroococcum alone or in combination with carbosulfan (1 or 2%) was not effectie in controlling Heterodera avenae. Shoot weight and grain weight increased significantly over control only in carbofuran and Azoobacter + carbosulfan treatments while other growth characters were on par in all other treatments.
