Evaluation of fungicides against leaf rust of wheat incited by Puccinia triticina Eriks

Abstract

The present study entitled “Evaluation of fungicides against leaf rust of wheat incited by Puccinia triticina Eriks” was conducted to evaluate effect of six different fungicides (T1)Azoxystrobin 18.2% w/w + Cyproconazole 7.3% w/w SC @ 0.1% (T2) Azoxystrobin 18.2% + Difenoconazole 11.4% w/w SC @ 0.1%, (T3) Tebuconazole 50% +Trifloxystrobin 25% WG @ 0.1%, (T4) Mancozeb75%WP @ 0.25%, (T5) Propiconazole 25% EC @ 0.1%, (T6) Tebuconazole 25.9% w/w @ 0.1% against the leaf rust of wheat, the study’s finding showed that, of the different fungicides treatments, (T3) Tebuconazole 50% + Trifloxystrobin 25% WG @ 0.1% was the most successful, as evidenced by the significantly higher grain yield (29.11 q/ha), plant height (80.95 cm), 1000 grain weight (49.19 gm) and dry matter yield (54.11 q/ha), all these results superior over the tested fungicides and untreated control.
