Abstract

Insecticides have been the first line of defense against insect pests attacking cucumber on account of their effectiveness, ease of application and immediate results. Compounds with novel modes of action, possessing good insecticidal activity against insect pests infesting cucumber, have been advocated for use in the cucumber ecosystem in recent times in general. Hence, under such circumstances, a newer formulation of insecticide needs to be evaluated for its bio-efficacy against major pests of cucumber as the first line of defense. A field experiment was conducted to evaluate the bio-efficacy and phytotoxicity of Flubendiamide 90 + Deltamethrin 60-150 SC (15% w/v) against cucumber pests like red pumpkin beetle, fruit fly and cucumber moth for two seasons. The treatments were: T1- Flubendiamide 90 + Deltamethrin 60-150 SC @ 15+10 g a.i./ha; T2- Flubendiamide 90 + Deltamethrin 60-150 SC @ 18+12g a.i./ha; T3- Flubendiamide 90 + Deltamethrin 60-150 SC @ 22.5+15g a.i./ha; T4- Deltamethrin

Keywords

Bioefficacy, phytotoxicity, red pumpkin beetle, fruit fly and cucumber moth.

Conclusion

Among all the tested chemicals flubendiamide 90 + deltamethrin, 60-150 SC @ 22.5+15g a. i./ha was found to be significantly superior in reducing the per cent leaf damage and per cent fruit damage caused by pumpkin beetle, fruit fly, and cucumber moth by suppressing the population. The plots treated with flubendiamide 90 + deltamethrin 60-150 SC @ 22.5+15g a. i./ha produced the maximum fruit yield than other treatments and had less impact on natural enemies so it can be used for the effective management of cucumber pests in the field. Further, flubendiamide 90 + deltamethrin 60-150 SC @ 45+30 g a. i./ha and 90+60 g a. i./ha did not cause phytotoxicity to cucumber crop.
