Abstract

This study was to evaluate the safety of commonly used pesticides on mulberry for commonly used silkworms in Chongqing, and to provide reference for pest control and scientific pesticides using in mulberry orchards in silkworm areas. 5 fungicides and 5 insecticides were sprayed on mulberry, mulberry leaves were used to feed the 3rd instar silkworms 15~40 days later. The results showed that there was no symptoms of poisoning and death to the 3rd instar silkworms and there was no difference in economic indexes between treatment groups and control group, the treatment groups were separately sprayed with 50% carbendazim WP, 70% thiophanate-methyl WP, 10% difenoconazole WDG, 50% procymidone WP, 50% boscalid WDG, 10% imidacloprid WP and 8% chlorfenapyr ME, this showed that these pesticides were safe for sericulture, to avoid affecting the quality of cocoons, leaves should be picked 15 days later. However, there had potential safety risks for silkworms when spraying with 80% cyromazine WDG and 25% thiamethoxam WDG, in order to ensure the safety of silkworms, spraying must be done more than 40 days. 2.5% bifenthrin EW had highly toxic and a long residual period to silkworms, it has been forbidden to use in mulberry fields for sericultural production.
