ABSTRACT
One of the major constraints in silk cocoon production is the occurrence of diseases during silkworm rearing. Among the several diseases of mulberry silkworm, Bombyx mori L., grasserie, a viral disease is most serious due to its occurrence throughout the year. To overcome this constraint, an integrated silkworm disease management package was suggested and trials were test verified at farmers holdings in different sericultural areas of Tamil Nadu. Trials on integrated grasserie disease management conducted at Coimbatore, Erode and Salem districts showed an additional yield of silkworm cocoons ranging from 7.2 to 18 kgs/ 100 dfls, 14.0 to 17.6 kgs/ 100 dfls and 9.5 to 13.0 kgs/ 100 dfls, respectively.
Key words :
Additional yield, Bombyx mori, Grasserie, Integrated disease management, Mulberry silkworm.
