Abstract:
An experiment was carried out to determine the efficacy of some eco
friendly seed treatments and fungicidal treatments against leaf blight
iBipolaris sorokinianai and grain yield of wheat. Among the different eco
friendly treatments, the highest reduction of incidence of seed borne
Bipolaris sorokiniana and increasing seed germination and seed yield (3.85
t/ha) was obtained by manually sorted healthy looking seed treated with hot
water (T8) followed by farmer's saved seed treated with hot water (T1).
Significant reduction of incidence of same fungus was achieved by treating
seeds with solar heat and polythene solarization. The rest of the treatments
have some remarkable effect in controlling the disease and increasing seed
yield of wheat. Among the fungicidal treatments, apparently healthy seed+
foliar spraying of Tilt-250 EC (T4) was found best in reducing the leaf
infection and increasing the seed yield (4.02 t/ha) which was followed by
farmer's saved seed+ foliar spraying of Tilt (T3) and apparently healthy
seed+ foliar spraying of Proud -250 EC(T
Another two fungicides Proven-
250 EC and Propicon also gave the better performance in reducing the leaf infection and increasing seed yield in comparison to control.
