Abstract
An experiment was carried out to determine the comparative efficacy of
Vitavax-200 as seed treating chemical; Tilt-250 EC, Bavistin and Pencozeb
as foliar spray in controlling leaf blight of wheat caused by Bipolaris
sorokiniana under field conditions. The single effect of Vitavax-200, Tilt250
EC, Bavistin and Pencozeb were found less effective than that of
combined effect of Vitavax-200 with Tih-2S0 EC. Vitavax-200 with
Pencozeb and Vitavax-200 with Bavistin. The effect of seed treatment with
Vitavax- 200 followed by subsequent three foliar sprays with Tilt-250 EC
(Ts) has been found significantly more effective than the other single and
combined effects in reducing leaf blight severity of wheat. Maximum grain
yield 4.05 t/ha was found under the treatment Ts (Vitavax-200 with three
sprays of Tilt-250 EC) which increased grain yield by 44.64% over
untreated control. The treatment T7 resulted statistically similar effect to that
of treatment Ts (Vitavax-200 with two sprays of Tilt-250 EC) in reducing
leafblight severity and increasing grain yield of wheat over control.
