In recent years organic formulations involved in the biological control of insect-pests of economically important plants have been of great value in the field of agriculture to rule out the use of hazardous pesticides. Application of insecticides of botanical origin is becoming a simple and sustainable method of pest control. In this investigation Wedelia chinensis and Cymbopogan citratus were selected for mortality of scale insects. Bioactive principles in these herbs were analysed by GC-MS. Significant mortality of adult scale insects has been attributed to the presence of Butyl butyrate, Bis (3,3,5-Trimethyl hexyl) adipate in Wedelia chinensis and Benzofuran in Cymbopogan citratus in the herbal formulation

Acute oral toxicity of organic grapes produced by microbial fertigation and foliar spray of panchagavya was evaluated in albino rats. In the present study, albino wistar rats were administered Vitis vinifera fruit extract orally with dosages of 200, 400 and 800 mg Kg-1 body weight. Mortality, body weight and haematological parameters were observed for 7 days after treatment. Effect of methanolic extract of Vitis vinifera on pylorus ligated rats and HCl-Ethanol induced gastric lesion in rats was studied simultaneously. The methanol extract of Vitis vinifera was found to be non toxic and safe as oral intake. The methanol extract of organic grapes was found to possess a protective effect against gastric ulcer and acidity.
