The study was conducted at the On Farm Research Division (OFRD) farm, Rangpur from 2002-2003 to 2004-2005 to see the effect of inorganic fertilizers along with organic manure and mungbean residue on soil properties and yield of crops. For the first crop (maize), there were five treatments. After harvest of maize, mungbean and dhaincha (Sesbania) seeds were sown as per treatments. For T. Aman ri...

BACKGROUND Metrafenone has been used in Europe in integrated pest management programmes since 2006 to control powdery mildews, including Erysiphe necator. Its exact mode of action is not known, but it is unique among fungicide classes used in powdery mildew management. Recently, resistance to metrafenone was reported in Blumeria graminis f. sp. tritici. In this study we investigated metrafenone...

Grapevine powdery mildew, caused by the ascomycete Erysiphe necator, is a major threat to grapes worldwide. Despite its global impact on grape production, E. necator is sensitive to adverse environmental conditions, such as excess heat, free water and UV radiation. Using detached leaf co-culture assays, 3-d-old single colonies of E. necator were exposed to 1, 2 or 3 consecutive d of punctuated ...

Sesbania Grandiflora (Family: Leguminosae) is a medicinal plant used as tumor suppressant agent in Ayurveda, a traditional system of medicine practiced in sub-continental India. The aim of the study was to systematically investigate and reveal the cytotoxic potential of sesbania grandiflora bark extract [petroleum ether (BP), Chloroform (BC), Methanol extract (BM) and Aqueous extract (BA)] agai...

Some of the parameters that determine flooding resistance-and consequently habitat zonation-were investigated in four neotropical trees (Schizolobium parahyba, Sebastiania commersoniana, Erythrina speciosa and Sesbania virgata). The constitutive parameters of seeds (size, nature and amount of reserves) only partly influenced resistance to flooding, mainly through a high carbohydrate : size rati...

Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the glyphosate I 50 values (rate required to cause a 50% re...

Crude extracts and active principles from medicinal plants have shown potential role in controlling plant diseases in glasshouses as well as in fields as one of the safest and ecofriendly methods. The effect of nor-securinine (an alkaloid) isolated from Phyllanthus amarus has been seen against spore germination of some fungi (Alternaria brassicae, A. solani, Curvularia pennisetti, Curvularia sp...
