जैव कीटनाशक और कृषि में उनकी भूमिका Biopesticides is a type of pest management technique that uses natural microorganisms, plants, and other biological materials to control pests and diseases in agriculture. Biopesticides have attracted significant attention in recent years due to their eco-friendly nature, low toxicity, and ability to target specific pests. जैव कीटनाशक एक प्रकार की कीट प्रबंधन तकनीक है जो कृषि में कीटों और बीमारियों को नियंत्रित करने के लिए प्राकृतिक सूक्ष्मजीवों, पौधों और अन्य जैविक सामग्रियों का उपयोग करती है। जैव कीटनाशकों ने हाल के वर्षों में अपने पर्यावरण के अनुकूल प्रकृति, कम विषाक्तता और विशिष्ट कीटों को लक्षित करने की क्षमता के कारण महत्वपूर्ण ध्यान आकर्षित किया है। इस लेख में हम आधुनिक कृषि पर जैव कीटनाशकों, उनके प्रभाव और भविष्य में उनकी भूमिका पर चर्चा करेंगे। आधुनिक कृषि में जैव कीटनाशकों के उपयोग के कई लाभ हैं। सबसे पहले, जैव कीटनाशक मानव स्वास्थ्य और पर्यावरण के लिए सुरक्षित हैं। रासायनिक कीटनाशकों के विपरीत, जैव कीटनाशक मिट्टी या पानी में जहरीले अवशेष नहीं छोड़ते हैं, जो पारिस्थितिकी तंत्र को नुकसान पहुंचा सकते हैं। दूसरे, फसलों में कीटों और रोगों को नियंत्रित करने के लिए जैव कीटनाशक अत्यधिक प्रभावी होते हैं। वे कीट के जीवन चक्र को बाधित करके या कीट के शरीर रचना के विशिष्ट भागों पर हमला करके...

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. Biopesticide in India  In India, so far only 12 types of biopesticides have been registered under the Insecticide Act, 1968. Neem based pesticides, Bacillus thuringiensis, NPV (Nuclear Polyhedrosis Virus) and Trichoderma are the major biopesticides produced and used in India. Whereas more than 190 synthetics are registered for use as chemical pesticides. Most of the biopesticides find use in public health, except a few that are used in agriculture.   Consumption of biopesticides has increased from 219 metric tons in 1996-97 to 683 metric tons in 2000-01, and about 85% of the biopesticides used are neem based products. Consumption of chemical pesticides has significantly fallen from 56,114 MT to 43,584 MT during the same period. Table 1:   Annual availability of...

कीट प्रबंधन में जैव कीटनाशकों की भूमिका More and more quantities of chemicals are used for agriculture  intensification to feed on ever growing population. In fact the pest induced loss is on the rise despite increasing usage of pesticide, fortunately, realizing of the negative effect of these chemicals on natural and natural resources like pollution.  Pesticide residue, pesticide resistance etc, have forced many to shift focus on to more reliable,  Sustainable and environment friendly agents of pest control, the bio pesticides.  In view of this demand and Governments efforts to mitigate climate change, biopesticides are going to play an important role in future pest management programme. Biopesticide :- Bio pesticides include " naturally occurring  substance that control pest (biochemical pesticides), microorganism that control pest (microbial pesticide) and pesticidal substances produced by plants containing added genetic materials (Plant-in corporate protectants)  Biopesticides are biochemical pesticides that are naturally occurring substance that control pest by non toxic mechanism. Biopesticides are natural plant products belonging to the secondary metabolites include alkaloids, terpenoids, phenolics etc. Potential of Biopesticides in IPM :- Biopesticides fall into three major classes : Microbial pesticide, Which consist of bacteria, entomopathogenic fungi and viruses.  Entomopathogenic nematodes are also often classed as microbial pesticides, even though they are multi cellular. Plant Incorporated Protectants (PIPs), which have genetic material from other species...
