Abstract:

Study on assessing the toxic effects of fungicides on silkworm (Bombyx mori L.) and also on cocoon and silk quality parameters revealed that carbendazim 50% WP and wettable sulphur 80% WP at 0.1% were found to have no toxic effect by showing zero larval mortality at three days after treatment. The larval weight and larval length of 29.33 g and 5.73 cm respectively in carbendazim 50% WP and 29.10 g and 5.42 cm) in wettable sulphur 80% WP was found to be higher than other fungicidal treatments. The cocoon characters like cocoon weight of 11.37g and 11.22 g, pupal weight of 8.40 g and 8.29 g, shell weight of 2.95 g and 2.93 g, shell ratio of 26.12 and 26.11 per cent and cocoon yield of 398.34 g/dfl and 392.70 g/dfl was higher in carbendazim 50% WP and wettable sulphur 80% WP at 0.1 per cent concentration respectively. The silk quality traits like filament length of 857.02 m and 820.58 m, filament weight of 0.20 g and 0.21 g and denier of 2.14 % and 2.27 % was found to be higher in carbendazim 50% WP and wettable sulphur 80% WP treatment at 0.1 concentration.
