| dc.description.abstract | During the present investigation, attempt was made to find out effective chemicals for the management of pink mealybug on mulberry. Initially, chemicals with novel modes of action were assessed in the laboratory. Based on the laboratory results, promising insecticides were assessed in the field at different doses against mealybug. Data was also generated on safety of the treated mulberry leaves for silkworm rearing, phytotoxicity on mulberry and safety to natural enemies. The field experiment results revealed that among the insecticides, dinotefuron 20 SG @ 0.25 g/l exhibited higher mealybug mortality at both 7 and 15 days after spraying (DAS), followed by pymetrozine 50 WG @ 0.6 g/l and azadirachtin 1 % @ 2 ml/l. Further, these chemicals were found non phytotoxic to mulberry and safer to coccinellid beetles, a prominent natural enemy of mealybug. Maximum mulberry leaf yield was recorded in dinotefuron 20 SG @ 0.25 g/l. Dinotefuron 20 SG, pymetrozine 50 WG and azadirachtin 1 % at different doses were found safer to silkworms even at 10 DAS and exhibited better rearing and reeling parameters. On the contrary, flonicamid 50 WG 0.3 g/l exhibited phytotoxicity and affected silkworm rearing. | en_US |
