Abstract:
The experiment was conducted to study the damage potentiality and eco-friendly
management of red pumpkin beetle and cucurbit fruit fly on squash during the period
from October, 2018 to March, 2019. The experiment consisted of seven different
treatments vizT
= Cultural method

= Applying Sevin 50 WP @ 1.5g/pit + using vineger trap.T
= Mechanical
control method at 7 days interval + using Pheromone trap.T
= Applying Sevin 50
WP@1.5g/pit+ Spraying Folithion 50 EC@ 1.0 ml/L of water at 15 days interval.T

=
Spraying Pychlorex 20 EC @ 1.0 ml/L of water at 15 days interval + using Funnel
Pheromone trap.T
= Spraying Predator 50 EC @ 1.0 ml/L of water at 15 days interval +
using mashed sweet gourd trap.T
