Organic Pesticide
About the Practice
Neem kernels 1 kg is powdered well and soaked in 5 liters of water for 12 hours and then filtered. This filtrate is added with 400 gms of dehydrated limestone powder and kept as such for 12 hours. Then, this solution can be filtered through a fine cotton cloth. This mixture should be sprayed at the rate of 1250 ml / 45 liters of water with power sprayer for 1 acre. Spraying of this mixture is advisable to be done in the morning or in the evening. Floral Mixture to enhance flowering and Fruiting About 20 flowers of each of the following plants are taken: Sembaruthi (Hibiscus rosasinensis), malai arali (Plumeria rubra), erukku (Calotropis gigantean) Thanga arali (Neerium oleander) crotons, jasmine and nanadhiyavattam (Ervatamia divaricata) are ground into fine paste and this is mixed well with 1 litre of water. Then, the mixture is filtered through a fine cotton cloth. The filtrate 20 ml is added with 1 liter of water and sprayed at flowering stage. This spray will help enhancing flowering and thereby increase the field. Herbal Pesticide The fresh leaves of sembaruthi (Hibiscus rosa sinensis) , Aavarai (Cassia auriculata) , Sitapal (Annona squamosa), neem, pungam (Pongamia pinnata) and black croton plants are taken in 20 numbers each. All the leaves have to be ground as a paste and mixed with 2 liters of water, filtered and kept aside. Neem kernel 1 kg can be crushed well and soaked in 5 liters of water for 12 hours. Then the solution is filtered through a fine cotton cloth. This filtrate is to be mixed with previously prepared leaf extract. This mixture 300 ml can be taken in a sprayer (of 10 liters capacity) & filled with water for remaining quantity and sprayed on the crop plants. Shri. M Singaravelu (age 24 years) living in Sankaralingapuram village of Virudhunagar District has been working as a horticulture supervisor. In his experimentation he developed some organic practices for crop protection. Some of these practices are described below: Preparation of Natural Herbal Mixture Neem kernels 1 kg is powdered well and soaked in 5 liters of water for 12 hours and then filtered. This filtrate is added with 400 gms of dehydrated limestone powder and kept as such for 12 hours. Then, this solution can be filtered through a fine cotton cloth. This mixture should be sprayed at the rate of 1250 ml / 45 liters of water with power sprayer for 1 acre. Spraying of this mixture is advisable to be done in the morning or in the evening. Advantages: The spray will be found effective to control aphids and diseases like leaf curl and blast in brinjal, chillie, cotton , bhendi and paddy crop. Floral Mixture to Enhance flowering and Fruiting About 20 flowers of each of the following plants are taken: Sembaruthi (Hibiscus rosasinensis) , malai arali (Plumeria rubra), erukku (Calotropis gigantean) Thanga arali (Neerium oleander) crotons, jasmine and nanadhiyavattam (Ervatamia divaricata) are ground into fine paste and this is mixed well with 1 litre of water. Then, the mixture is filtered through a fine cotton cloth. The filtrate 20 ml is added with 1 liter of water and sprayed at flowering stage. This spray will help enhancing flowering and thereby increase the field. The efficiency and effectiveness of this mixture is found effective in fruit trees like mango and sapota. It has also been proved in 25 cent tomato crop with good yield of 1750 kg.

This mixture 300 ml can be taken in a sprayer (of 10 liters capacity) & filled with water for remaining quantity and sprayed on the crop plants. This spray will found effective in controlling the insect pests by drying and shedding them.

"Effect of neem extract on the cotton aphid - Neem-based insecticides efficiently control several aphid species in the field (Lowery et al., 1993). In the laboratory, the aqueous extract of neem seeds was efficient against the aphid A. gossypii, causing nymph mortality and reducing their survival period and fecundity."
