ABSTRACT: The present work has been carried out, on various parameters in Cajanus cajan Mill. cvs. TTB-7 and HYD-3C. The slurry of Metalaxyl (a fungicide) and Gaucho (an insectoside) were made, based on the formulation viz., recommended dosage, above recommended, below recommended and in combination dosage of both the pesticides. On termination day, Metalaxyl and Gaucho in both individually and in combination treatments of higher dosages have severely affected on germination and seedling vigour. When compare to control, the chlorophyll content and dry matter were greatly reduced at in-combination dosage than any other concentrations. But lower dosages did not affect much on germination and growth parameters. The calculated results of vigour index, tolerance index were decreased and the percent phytotoxicity was increased along with the increased and in combination dosages of both the pesticides. The relative susceptibility of HYD-3C has been observed, in both Metalaxyl and Gaucho than TTB-7. When compared with all these treatments, the experimental results clearly showed that better response of the above pulse crop occurred at control.
