Seed coating of greengram (Vigna radiata) with nine plants oils (1 edible; 8 non-edible and medicinal) gave significant protection against pulse beetle, Callosobruchus chinensis Linn, as compared to untreated control. The oil coating, 4-6 h after treatment, gave complete protection in all the oils evaluated at the treatment doses of 2.5, 5 and 10 ml / kg seeds while protection, 3,6 and 9 months after treatment was partial to complete against the pulse beetle. Neem (Azadirachta indica A. Juss), mehndi (Lawsonia inermis L.), malkangni (Celastrus paniculatus L.), and babchi (Psoralea corylifolia L), oils at 10 ml / kg seed were effective, even after 6 months of treatment; the later three were effective in controlling C. chinensis, even after 9 months of the oil treatment The germination test carried out with the oil treated seeds (4 to 6 h, and, 3,6 and 9 months, post-treatment), when the treated seeds were given 8 h exposure to sun, revealed nonsignificant differences among the treatments and untreated control. However, the germination of oil treated seeds, if not exposed to sun for 8 h, was adversely affected, especially so in case of babchi oil treatment.
