एग्रो-इकोसिस्टम विश्लेषण पर आधारित पादप स्वास्थ्य प्रबंधन Agricultural crops are widely distributed in different agro-ecological regions and thus in different regions the pest management practices differ on various crops. Decision making in pest management requires an analysis of the agro eco system. During the late 90s, FAO started advocating Agro-Ecosystem Analysis (AESA) based IPM (Gurr et al., 2004). Agro Ecosystem Analysis (AESA) is an approach, which can be employed by extension functionaries and farmers to analyze the field situations and monitor the population of pests, defenders, soil conditions, plant health and the influence of climatic factors to make informed decisions for growing a healthy crop. In AESA, farmers observe the crop, analyze...

The various cultural practices have been grouped as under. Preparation of nurseries or main fields free from pest infestation by removing plant debris, trimming of bunds, treating of soil and deep summer ploughing which kills various stages of pests. Proper drainage system in field is to be adopted. Testing of soil for nutrients deficiencies on the basis of which fertilizers should be applied. Selection of clean and certified seeds and treating seeds with fungicide or biopesticides before sowing for seed borne...

Importance of Hosted Plant Resistance (HPR) in Integrated Pest Management (IPM) of Wheat मेजबान पौध प्रतिरोध (Host Plant Resistance, HPR) को रेगिनाल्ड एच. पेईंटर (1951) ने परिभाषित किया है l परिभाषा के अनुसार यह “पौधों के ऐसें गुण हैं, जो उनको कीटों से बचने, या सहन करने की या कीट क्षति के उपरांत आरोग्य होने शक्ति देते हैं, जिन परिस्थितियों में उसी जाति के पौधों को अधिक से अधिक नकुसान हो सकता है” l कीड़ों के प्रति पौध प्रतिरोध एक आनुवंशिक (heritable) गुण है जो पौधों में कीटों द्वारा होने वाली क्षति की परम सीमा को निरधारित करता है l प्रकृति में पोधे तीन प्रकार से अपना प्रतिरोध कीड़ों के प्रति प्रकट...

Eco-friendly integrated pest management: Dire need of hour कीड़े-मकोड़े फसल की पैदावार को अत्यधिक क्षति पहुँचाते हैं जिससे किसानों का परिश्रम बर्बाद हो जाता है। इन समस्यों के निवारण हेतु किसान रासायनिक कीटनाशकों का प्रयोग करते हैं । इस बात में कोई संदेह नहीं है कि रासायनिक कीटनाशक कीट प्रबन्धन के सफल हथियार है परन्तु इनके अनेकों दुष्परिणाम भी हैं। जीवनाशी के उपयोग से किसानों के मित्र जीव भी नष्ट हो गए। अधिक जीवनाशी उपयोग करने से जीवनाशी अवशेष फसलों में अधिक दिनों तक बना रहता है जो उपभोक्ता के स्वास्थ्य के लिये हानिकारक होता है । चना फली भेदक, सेमीलूपर, काला माहूँ जैसे कीटों से बचाव करने के लिए रासायनिक कीटनाशक...

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...

एकीकृत सुत्रकृमी (नि‍मेटोड) रोग प्रबंधन  Nematodes are parasites belonging to animal kingdom that are of concerned in the agricultural crop health. They belong to phylum Nemata, previously named Nemathelminthes or Aschelmnthes, several hundreds of nematode species are known to feed on plants as parasites and cause a variety of diseases.  Most of the damage by nematodes is caused by secretion injected into plants while they feed. This secretion, called saliva, is produced in three glands, from where it flows into oesophagus and is injected through stylet. The males of species generally may not penetrate roots, but females invariably get established on roots and are responsible for destruction of the host. Nematode saliva...
