Abstract

Field experiments were conducted at College of Agriculture, Chamarajanagara during 2022-23 to evaluate the efficacy of pesticides viz., Chlorfenapyr 10 % SC @ 1.5 ml/l, Wettable Sulphur 80 WP @ 2 g/l, Orgomite @ 2.5 ml/l, Era Safeguard @ 2.5 ml/l and Azadirachtin 1 % @ 2 ml/l along with water spray and untreated control against mites and mulberry leaf roller. The study revealed that the maximum mortality of mites was observed in Chlorfenapyr 10 % SC @ 1.5 ml/l (100 %) followed by Orgomite @ 2.5 ml/l (81.38 %), Wettable Sulphur 80 WP @ 2 g/l (67.78 %), Era Safeguard @ 2.5 ml/l (37.45 %) and Azadirachtin 1 % @ 2 ml/l (29.80 %) in the decreasing order of their efficacy at 3 DAS. The maximum mortality of leaf roller was observed in Chlorfenapyr 10 % SC @ 1.5 ml/l (100 %) followed by Era Safeguard @ 2.5 ml/l (99.10 %), Orgomite @ 2.5 ml/l (96.41 %), Azadirachtin 1 % @ 2 ml/l (93.00 %) and Wettable Sulphur 80 WP @ 2 g/l (49.36 %) at 7 DAS. Chlorfenapyr 10 % SC @ 1.5 ml/l and Orgomite @ 2.5 ml/l were found effective against both mites (Polyphagotarsonemus latus) and leaf roller (Diaphania pulverulentalis) without any phytotoxic effect on mulberry

Mulberry, Pesticides, Silkworm, Mites, Leaf roller

Conclusion

The present findings suggest that spraying of Chlorfenapyr 10 % SC @ 1.5 ml/l was found effective in controlling both mites and leaf roller in mulberry followed by Orgomite @ 2.5 ml/l which helps in the production of good quality and quantity of mulberry leaf
