EVALUATION OF DIFENOCONAZOLE 3% WS AS SEED TREATMENT AGAINST KARNAL BUNT IN WHEAT BIJENDER KUMA

Abstract

The present study was undertaken to evaluate the efficacy of difenoconazole 3% WS against Karnal bunt along
with some recommended fungicide. Based on the data of two crop seasons it can be concluded that the spraying
of propiconazole 25% EC @ 500ml/ha at anthesis was most effective fungicide both in terms of managing the
Karnal bunt of wheat and improving the yield. Among the seed treatments, seed treatment with thiram @ 3.00g/
kg seed was found most effective in improving the field emergence. However, the test fungicide difenoconazole
3% WS had no beneficial effects on field emergence, disease management and yield as compare to check.
Nevertheless, the test fungicide difenoconazole 3% WS had no phytotoxic effects on wheat plants during both the
crop seasons even at the highest dose tested.
