फसलों मे कीट नि‍यंत्रण के लि‍ए जैवि‍क कीटनाशकों का प्रयोग Pesticides having biological origin i.e., viruses, bacteria, pheromones, plant or animal compounds are known as biopesticides. They are natural in origin derived from animals, plants, bacteria, and certain non-synthetic minerals. Bio-pesticides are highly specific affecting only the targeted pest or closely related pests. They are safer for living beings. Biopesticides are one of the promising alternatives to manage environmental pollution and subsequently has gained interest in view of the growing demands for organic food. Biopesticides can successfully be used for specific crops and niche areas as a component of IPM.

मृदा पोषण में तरल जैवि‍क खाद की भूमिका Manures are organic materials with plant nutrients in small concentrations. Organic manures are the main source of replenishing soil fertility. Organic farming is an internationally regulated legally enforced and standardized alternative paradigm relies on ecological processes, biodiversity for sustaining the health of soil. Solid organic fertilizer, cattle manure and green manure are the most nutritive organic fertilizers with an average nitrogen (N) content of 1.5%. Now a days Liquid Organic Manure has largely remained in background of bio-dynamic farming. The plant can absorb nutrients about 20 times fast through the leaves than applied through the soil. Therefore, liquid manures are helpful to overcome temporary nutrient shortages. In organic...

नीम के बायोपेस्टीसाइड: एकीकृत कीट प्रबंधन के लिए उपयुक्त जैव कीटनाशक Continuous and excessive use of chemical pesticides over a period of time has resulted in serious problems such as development of insect resistance, insecticide-induced resurgence of insect-pests, toxicity to non-target organisms and also to human beings. Now there is an urgent need to evolve an alternate coherent pest management programme, which is effective and environment friendly. It would be appropriate to identify chemicals, which render crop plants unattractive or unpalatable for feeding by insect-pests, and at the same time are fully biodegradable. Several plant products possess the property of making crop foliage unattractive for feeding, and hence, form an important component of...
