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
