Description |
Treating the seeds with Dithane M-45 (® 0.25%) was found to be effective under field conditions in increasing the groundnut seed emergence as well as in minimising the collar rot disease incidence. More collar rot disease incidence was observed on 21 days old groundnut seedlings than on 14 days old seedlings raised from the seeds treated· with Dithane M-45 and cow urine indicating the need to evolve a chemical that protects seedlings for a longer period. However, on comparative basis, cow urine treatment was less effective in increasing seed emergence and minimising collar rot disease. Drenching the soil around the seedlings with Dithane M-45 solution, three weeks after sowing was also found to be effective in lowerin~ collar r~t incidence. Drenching the soil with cow urine {1:3 cow urine: water) was found to be the next best in reducing collar rot disease. Dithane M-45 was effective not only as seed dresser but also useful for drenching the soil for disease management. The same fungicide was found to be effective in increasing vegetative growth of groundnut plant, particularly in increasing the number of root nodules per plant as well as in increasing the test weight. Plants raised from cow urine treated groundnut seeds registered slightly more pods. per plant. But significantly more number of pods per plot was registered in the plots sown with Dithane M-45 treated seeds. Tests conducting under green house conditions also broadly projected the same results as in field test. Treating the seeds with Dithane M-45 or with cow urine resulted in low collar rot incidence and similar trend was noticed in seed emergence also. In blotter method, more percentage of germination was noticed in the seeds treated with Dithane M-45 (2.5g/Kg seed). Therefore, the study clearly indicated the multiple beneficial effects of Dithane M-45 in disease management. Cow urine and neem cake extracts also indicated their effectiveness in managing the disease and therefore, they can be thought of as an a |
