Last update: 08/12/2006
Summary Application of chemical pesticides has been causing manifold ill consequences to the agro-ecosystem and its natural functioning. Resource-poor farmers in the rabi season face the menace of various insect pests and have to incur huge cost for buying chemical pesticides. Neem pesticides can be domestically prepared and used in own fields which can control pest population to a great extent. It is also environment friendly and takes care of farmers’ health while spraying. Brinjal fruit and shoot borer, different aphids, diamond back moth of cabbage, thrips of chilli, Tryporyza of paddy and many other commonly found pests of vegetables can be effectively controlled by it.

Challenge/Issue Uncontrolled and non-judicious application of chemical pesticide has spelt vicious consequences on the agro-ecosystem. Some prominent ones are – development of pest resistance, soil and water pollution, health hazards of farmers etc. Moreover, the high cost of pesticide (including the neem-based biopesticides) is also often beyond the financial capacity of the marginal and resource-poor farmers. Especially, during the vegetable cultivation, this problems stands high as farmers, anyhow, are to protect their high value crops from pests.
• Keep polythene sheet/tarpaulin/clothes under the tree when fruits turn yellow (alternatively keep the place under the tree clean)
• Shake tree branches gently
• Collect fruits immediately (pesticidal action of fruits will be reduced if left unattended for more than 4-5 days)
• Avoid collecting brown/livestock trampled fruits

• wash collected fruits by rubbing within palms inside a bucket
• Rub fruits on irregular or rough surface to remove the fleshy part from the seed
• Wash seeds thoroughly and leave to air-dry on jute bags
• Collect and keep dry seeds in bamboo basket/cloth bag to ensure free air movement (air tight condition may invite fungal attack)
• Seeds should be three months old before application. It won’t also be more than 8-10 months

• Eliminate the seed coat and grind one day before spray (take care that oil do not come out during grinding)
• Keep the ground seeds in clean water for 6-7 hours
• Keep on stirring the water with a wooden stick until the mixture turns milk white
• Sieve the mixture by a clean cloth
• Add adjuvant with the mixture and spray on and below the leaves of affected plants @ 50-60 g/L of water at 10 days interval, particularly in afternoon hours.

• Apply unused material in soil as manure; it will also control nematode infestation.
