    EFFECT OF SEED TREATMENT WITH SOME BOTANICALS ON SEEDLING GROWTH AND SEVERITY OF BIPOLARIS LEAF BLIGHT (Bipolaris sorokiniana) OF WHEAT
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2008-07) Rahmani, M. M.; Islam, M. A.; Aminuzzaman, F. M.; Islam, M. R.
    An experiment was conducted to find out the effect of 13 botanicals on seedling growth and severity of Bipolaris leaf blight (Bipolaris sorokinianov of wheat in a net house of Sher-e-Bangia Agricultural University, Dhaka, Bangladesh during November 2006 to March 2007. It was found that seed treatment with Allium cepa, A. sativum, Curcuma longa, Aegle marmelos, Lawsonia alba. Allamanda cathanica extracts caused considerable increase in germination and seedling growth. Pre-sowing treatment of seeds with all of the plant extracts caused significant reduction in disease severity over control. The severity index values under control were 1.55.2.00.3.22.4.55,4.66 and 4.66, respectively at flag leaf. booting, panicle initiation, !lowering, milk and hard dough stages of wheat plants. Seed treatment with the materials reduced disease severity within the range of 0.33-1.22,0.99-1.77. 1.11-2.00. 1.22-2.22. 1.66- 3.00 and 200-3.83. respectively for the above mentioned growth stronges of the crop.

    EFFECT OF SOME SELECTED ECO-FRIENDLY TREATMENTS ON LEAF BLIGHT (Bipolaris sorokiniana) SEVERITY AND GRAIN YIELD OF WHEAT
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2008-07) Yesmin, S.; Aminuzzaman, F. M.; Islam, M. R.; Islam, M. T.
    An Experiment was conducted during 2006-2007 to study the effect of some eco-friendly treatments on severity of leaf bight (Bipolnris sorokinianm, number and weight of grain per spike and grain health of wheat. Seeds of wheat variety Kanchan were collected from a farmer of Bansal district. Apparently healthy seeds were sorted out from the seed lot. Both unsorted and apparently healthy seeds were treated with hot water at 50°C for 5 minutes, brine solution (2% wlv NaCI) for 15 minutes, sun drying for 14 hours and polythene solarization for 14 hours. Unsorted and apparently healthy seeds were planted and 0.05% boron solution was applied as foliar spray at tillering stage. Two checks were maintained, unsorted and apparently healthy seeds, and planted without any treatment. At all stages of data collection. the highest severity of leaf blight on flag leaf and penultimate leaf were recorded under control. where unsorted and untreated seeds were planted followed by the treatment where apparently healthy seeds were planted without any treatment. Other treatments caused significant reduction in leaf blight severity and percentage of diseased seeds as compared to control. The treatments gave significant increase in number and weight of grain per spike and percentage of healthy grain. Considering the above parameters, pre-sowing treatment of apparently healthy seeds with hot water, brine or sundrying were noted as effective ceo-friendly methods to reduce leaf blight severity and to increase grain yield and healthy seeds of wheat.

    EVALUATION OF SOME WHEAT VARIETIES AGAINST LEAF BLIGHT (Bipolaris sorokinianai
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Laila, L.; Aminuzzaman, F. M.; Islam, M. R.; Rayhan, S. J.; Tania, S. N.
    A net house experiment was carried out in the field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to evaluate ten wheat varieties against leaf blight (Bipolaris sorokiniana). The wheat seeds of varieties Sonalika, Kanchan, Barkat, Shatabdi, Aghrani, Pavon-76, Akbar, Gourab, Sourav and Protiva were collected from Banngladesh Agricultural Research Institute (BARl), Gazipur. At ear initiation stage, flowering stage, milking stage and hard dough stage minimum disease severity was recorded in the variety Shatabdi and maximum in the variety Sonalika. The highest number of grains/ear (36.95) and number of healthy grains/ear (36.43) were recorded in the variety Shatabdi The highest 1000-seed weight (43.1Og) were recorded in the variety Gourab and lowest in the variety Protiva. The highest grain yield/pot (5.97g) was recorded in the variety Gourab and lowest yield/pot (4.40g) in the variety Pavon-76. The highest straw yield /pot (14.13g) was recorded in the variety Barkat and lowest (9.IOg) in the variety Shatabdi.

    POTENTIALITY OF SEED TREATMENT WITH SOME PLANT EXTRACT TO CONTROL BIPOLARIS LEAF BLIGHT (Bipolaris sorokiniana) AND INCREASING YIELD OF WHEAT
    (Sher-e-Bangla Agricultural University Research System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2007-07) Islam, M. A.; Aminuzzaman, F. M.; Islam, M. R.; Ullah, M. W.
    A study was undertaken to evaluate the efficacy of plant extracts to control Bipolaris leaf blight (Bipolaris sorokiniana) and increasing grain yield of wheat. Water extracts of neem (Azadirachta indica). 'allamanda'(Allamallda cathartica), 'mehedi'(Lawsonia alba) leaves, 'bishkatali' (Polygonum hydropiper) shoot, 'garlic'(Allium sativum) clove, onion (Allium cepa) bulb, black cumin (Nigella sativa) seed, and ginger (Zingiber officinalis) rhizome were prepared at a concentration of I :2. Wheat seeds were treated with individual plant extracts. Seeds were also treated with Vitavax-200 for comparison. It was found that all the plant extracts except mehedi increased seed germination on blotter. A remarkable reduction in incidence of seed borne Bipolaris sorokiniana was achieved with the botanicals. The disease severity was the lowest under Vitavax-200, followed by bishkatali and garlic extract. The highest disease severity was recorded under control. The increasd grain yield over control was achieved with extracts of onion, garlic, black cumin, ginger, bishkatali and neem. The efficacy of plant extracts to decrease disease severity and to increase zrain vield was more or less similar to that of Vitavax -200.
