(DEPARTMENT OF PLANT PATHOLOGY, 2006) Shahidullah, Mohammad
Experiments were conducted at Bangladesh Agricultural Research Institute (BARI) Joydebpur, Gazipur during 2004-2005 crop season. In field screening of 14 germplasms under natural infection pressure of Bipolaris leaf blight 3 reached as resistant (Chirya-7, Shatabdi and BAW-966) and 1 reached as moderately resistant (BA W -1006) to the disease. All the five fungicides (Avistin-O.l %, Hayconazole- 0.05%, Nuben-0.2%, Sulphotox-0.2% and Tilt0.05%) tested against Bipolaris sorokiniana, showed better performance over control. Among them Tilt appeared most effective and resulted against the PDI value of 72% and increased 108% grain yield over control. While effective dose of four fungicides namely folicur (0.05 and 0.10%), Hexaconazole (0.05 and 0.1 %), Fujione (0.05 and 0.1%) and Akanazole (0.05 and 0.1 %) were evaluated against Bipolaris leaf blight it was found that F2 D2.Exhibited most effective one in reducing the disease and increasing higher yield and it showed statistically similar to FIDI (Folicur, 0.05%) FID2 (Folicur, 0.1%) and F2Dl <, (Hexaconazole (0.05%). In another study on determining avoidable loss of wheat due to Bipolaris leaf blight indicated avoidable loss of27.05 and 14.20% were due to the disease respectively, in Kanchon (Susceptible) and Shatabdi (Moderately resistant) varieties.
