Abstract

A study on efficacy of certain insecticides against guava tea mosquito bug Helopeltis antonii Signoret was carried out at the farmer’s fields in Andipatti and Natham. It was observed that clothianidin 50%WDG @ 120 g/ha was the most effective giving 83.75% reduction over control. Buprofenzin 25%SC @1000 ml/ha, and thiacloprid 21.7%SC @500 ml/ha were the next and on par with each other. Thiamethoxam 25%WG @100 g/ha, profenophos 50EC @250 ml/ha, spinosad 45%SC @750 ml/ha and emamectin benzoate 5%SG @ 500 g/ha were observed to be less effective.
