ECO-FRIENDLY SEED TREATMENTS IN CONTROLLING BLACK POINT (Bipolaris sorokiniana) OF WHEAT (Pages : 35 - 42)

Effect of different eco-friendly seed treatments against of black point of wheat under lab and field condition was studied during the period from December-2007 to March-2008 at the laboratory and farm of Sher-e-Bangla Agricultural University. Twelve treatments were explored in this experiment namely farmers saved seed ((T1), apparently healthy seed (T2), farmer’s saved seed treated with brine solution (T3), apparently healthy seed treated with brine solution (T4), sun drying of farmer’s saved seed (T5), sun drying of apparently healthy seed (T6), farmer’s saved seed treated with hot water (T7), apparently healthy seed treated with hot water (T8), polythene solarization of farmer’s saved seed (T9), polythene solarization of apparently healthy seed (T10), farmer’s saved seed treated with Bavistin 50WP (T11) and Apparently healthy seed treated Bavistin 50WP (T12).The experiment was laid out in the Randomized Complete Block Design (RCBD) with three replications. The highest reduction of incidence of black point (Bipolaris sorokiniana) was recorded in the treatment T12. Among the eco-friendly treatments the highest reduction of incidence of seed infection over control was found in treatment T8 (apparently healthy seed treated with hot water) in blotter test. Brine solution, sundrying and polythene solarized farmer’s and apparently healthy seeds also resulted significantly reduced black point severity over control. The treatments, T6 also gave good result in reducing seed infection and increasing seed germination. Treatment T4 and T10 also increased seed germination and reduced the seed infection in field condition. Farmer’s saved seed treated with hot water, polythene solarization, brine solution and apparently healthy seeds showed moderate performances reducing black point severity over control (T1). The treatment T2 decreased 66.15% disease incidence though the maximum germination was increased up to 98.20% over untreated control under chemical Download
