Life Cycle and Abundance of Rice Leaf Folder, Cnaphalocrocis medinalis (Guenee) - A Review

The Rice leaf folder, (RLF) Cnaphalocrocis medinalis (Guenee) is widely distributed in rice growing areas in all over the world. The leaf folder has been considered a miner pest of rice growing areas but after the existence, high yielding and Basmati rice varieties increasing the importance of these pests.  Feeding rates of the first three larval instars rice leaf folder on rice plants were significantly lower than those of the fourth and fifth instars. The first three instars consumed less than 10% of the larva's total consumption. Feeding also decreased with increasing plant age. To understand about life cycle and management’s tactics is help to reduce the yield losses. In present review articles discusses about life cycle and abundance of rice leaf folder. Key word Cnaphalocrocis medinalis, life cycle, abundanc

Bt Cotton - Prospects and Challenges - A Review Article

India being agriculturally dominant country and over two-third of its entire working population are engaged in agriculture activities, in recent past, sectors like services. IT and manufacturing has shown smart progress but at same time progress in agriculture sectors have been sluggish. One can argue that this is more because of unpredictable climate/global warming. As the contribution of agriculture in country’s GDP is dwindling with time, and the latest prediction of the decelerated food production to a very alarming rate, the planners, executers and other agencies have started realizing for a significant change/reform in agriculture sector. There is a need to boots agriculture products with new technologies which can help increasing the production

Study on Insect Pest Succession of Brinjal Crop Ecosystem in Western Region of Uttar Pradesh, India

The present investigation was carried out during Kharif, 2011 at Crop Research Centre (CRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). During the studies on the insect-pests succession revealed that a total of eight insect species were found associated with brinjal crop at different crop growth stages. The first attack on the crop appeared in the one week after transplantation and continued up to till crop harvested. pests were found attacking on the crop were jassids (Amrasca biguttula biguttula), aphids (Aphis gossypii), white fly (Bemisia tabaci), leaf roller (Eublemma olivacae), shoot and fruit borer (Leucinodes orbonalis), epilachna beetle (Epilachna vigintioctopunctata), leaf webber (Psara bipunctalis) and grass hopper (Chrotogonus spp.). Among them, brinjal shoot and fruit borer (L. orbonalis) was recorded as major pest. Jassids (A. biguttula biguttula Ishida), aphid (A. gossypii Glov.) and epilachna beetle (E. viginitioctopunctata F.) were found to damage the crop moderately. Other insects pests recorded on the crop were of less importance and extent of damage caused by them was found without much economic loss. Keywords; Pest succession, Leucinodes orbonalis, Solanum melongena, damage

Food Production and Post Harvest Losses of Food Grains in India

The prevention of food wasted is enough o resolves hunger crises hunger crises. Food is the primary need to sustains the of human being life. Although, many techniques are engages to increase to food production and prevents of hunger and malnutrition of population. Presently, we produce sufficient agriculture food production, by using irrigation, pesticides, chemical fertilizer and high yielding variety. But these, are not seem to meet the enough food demands of present and future population. To encounter the hunger and secure food and nutritional security to need increasing the production and productivity, by using limited resources in sustainable manner and ensure the security of natural resources. The increasing productivity is the obvious choice to supply of food to increasing population. The other alternate way to provided food of available and increased population, the maximum efficiency use of every unit of resources including preventing pre and post harvest losses from insect-pests and diseases, proper and scientific storage of agriculture produces. Because post harvest losses about 30 % of the crops due to this reason.  One third of total foods production annual wasted due to lack of proper infrastructure unscientific handling. The total food lost, wasted in each year in the more than which would be solving the four times hunger crises of population. In the present review article focused on production and losses of agricultural produces

Isolation of Stem rot Disease Causing Organism of Brinjal and their in-vitro Inhibition with Fungicides and Bio-control Agents

Abstract Different strains of Sclerotinia sclerotiorum were isolated from the diseased samples collected from different hosts and locations. Among the 14 isolates, 12 isolates colonies covered the entire Petri plates within 96 hours but, two isolates from fababean and yellow mustard showed slow colony growth within 96 hours. All isolates produced sclerotia which were varied in number, but the fenugreek isolate produced maximum (43) number of sclerotia and lambs quarter isolate produced minimum number of sclerotia (12) on PDA medium. To examine inhibitory effect of fungicide on the mycelial growth of the pathogen, 9 fungicides were tested in vitro against Sclerotinia sclerotiorum, of those carbendazim, carboxin, topsin-M and carbendazim+ mancozeb (SAAF) were found most effective and inhibited the mycelial growth of pathogen up to 100 per cent at 0.05%, 0.1%, and 0.2% concentration. The effect of different bioagents viz., Trichoderma harzianum, T. viride, T. koningii, T. atroviride, T. longibraciatum, Aspergillus niger, Chaetomium globosome and Penicillium notatum in inhibiting the growth of Sclerotinia sclerotiorum was studied through -Dual Culture Technique‖. The data showed that among the eight biocontrol agent six were fond effective. The maximum inhibition was found by T. harzianum causing 70.82% inhibition of mycelial growth of the pathogen S. sclerotiorum

Studies on the Analgesic Potential of leaf Extracts of Allium humile on Swiss albino mice

Allium humile is a medicinal plant found at the Alpine Himalayas of Uttarakhand at altitute of 2500-3000 meters height of sea level. In India, Allium humile, is used by local people as a spice and in ethano-medicine. In the present study, Allium humile leaves were explored for their analgesic potential on experimental model and compared to standard drugs. Allium humile at the doses of 100 mg/kg and aspirin 25 mg/kg exhibited significant (p>0.05) inhibition of the control writhes at the rate of 64.25%, 44.54%, 44.54% and 59.89% respectively when compared to that of control. Thus, methanolic extract of the plant can be fully explored for its analgesic potential which has not been reported so far. The plant extract showed a relative low toxicity hence justifies the folkloric use of plant by the local people in Western Himalayan region for curing inflammation and painful conditions
