Abstract

Mung bean (Vigna radiata) is India's third most important pulse crop after chickpea and red gram. Several insect pests infested to mung bean crop and cause quality and quantity losses. The field experiment was carried out for the control of major insect pests on mung bean during Kharif season in 2019. The mung bean seeds were grown in three plot sizes of 5 m × 3m with 50 cm row to row and 20 cm plant to plant spacing. Randomly selected 10 plants from weekly intervals to record the population of insect pests before and after the spray of synthetic insecticides. The treatment of emamectin benzoate also found most effective against the population of whitefly and caused a maximum of 96.36% reduction while, the treatment of thiamethoxam was caused a maximum of 90.90% reduction. The treatment of emamectin benzoate 5 SG caused a maximum 93.02 percent reduction while, the treatment of thiamethoxam 25 WG caused a maximum 83.72 percent reduction in the population of jassids during the Kharif season 2019.Among both tested synthetic insecticides emamectin benzoate was found most effective against the population of jassids and white flyover untreated control.

Conclusion

The major insect pests were found whitefly and jassid in the present study. The treatment of emamectin benzoate was found most effective against the population of both whitefly and jassid while thiamethoxam was found less effective as compared to emamectin benzoate against the population of both insects.
