ABSTRACT
Mixing of five botanical products viz. neem kernel powder, neem leaf powder, eucalyptus leaf powder sarifa leaf powder and lantana leaf powder at the rate of 1.0 and 2.0 parts (W/W) per 100 parts of maize and paddy grllins proved to be protectants against S. cerealella causing adverse effects on development viz., less per cent of grain damage and less percentage of adult emergence. The grain damage done by 200 eggs during their development was found to be 59.96 and 10.89 per cent which was protected frem 63.94 to 96.61 and 76.58 to 94.49 per cent when grains were treated with various plant products in maize and paddy, respectively. Neem kernel powder proved to be most effective, while leaves of lantana the least. The germination of treated seeds was not impaired in any case during the exposure period of about eight months.
