भंडारण बीज के प्रबंधन में स्वदेशी प्रौद्योगिकियां Seeds should have a good storage facility, since seeds are the main input for next crop. Seeds should be stored in such a manner, that its germination capacity and vigour should not decline. The quality of seeds have critical influence on the ability of crops to become established and to realize their full potential of yield and value. Nearly 30% of the seeds are lost during storage period due to insects, rodents and microorganisms. Management of these insect pests by chemical method is not economically feasible but also unsafe for consumption. There is evidence of ash, sand,herbs used in ancient civilization, which have been credited with mystical power for increasing storage life of seed called as indigenous management practices.These methods avoid the use of chemicals and are inexpensive. Day by day the indigenous technique are lapsing hence, there is a need to generate awareness and dissemination of the eco friendly and low cost indigenous management practices among the farmers. Hence, this article briefly emphasize on important eco-friendly management practices. Insect’s management: Common salt In this method of seed storage 150 -200gm of available table salt in houses is mixed for a kg of cowpea seeds manually and stored in jute gunny bags it should stich properly. Due to this practice...

सेमिओकेमिकल्स - अनाज संग्रहीत कीट प्रबंधन के लिए एक वैकल्पिक विधि The rising concern on pesticide residue free products, reduction in cost of chemical control and resistance development had led to the search for an alternate eco friendly and economically feasible tactic. With advancement in the studies on various approaches in IPM of storage pests it is considered that semiochemicals particularly pheromones, have good potential for the suppression of stored-product insects by modifying or manipulating their behaviour. सेमिओकेमिकल्स - अनाज भंडारण कीट प्रबंधन के लिए एक वैकल्पिक विधि One third of world’s food grain is being lost during storage every year due to various biotic and abiotic factors. The biotic factors include attack of different pests like insects, fungi, bacteria, rodent’s etc. Abiotic factors like high grain temperature and moisture, along with dockage, broken kernels and lack of regular monitoring provide conditions that accelerate mold and insect development. Among which more damage is due to insect pest attack. In India, post-harvest losses caused by the unscientific storage, insects, rodents, micro-organisms etc., account for about 10 per cent of total food grains. Stored product pests are obligatory pests that can infest and damage a wide variety of food materials. Different stored grain pests have their own different ways of feeding and damaging the grains ultimately leading to huge...
