How do I control fruit fly and vine wilt in pointed gourd (parwal)?

Maggots in the fruit are from fruit fly, the main pest of parwal, managed with cucurbit fruit fly pheromone traps, prompt removal and destruction of infested and fallen fruit, and bagging on small plots. Sudden wilting of whole vines points to root or collar rot and wilt, which build up in poorly drained soil and where the same plot is cropped for years, so ensure good drainage on raised beds, avoid waterlogging, and remove and destroy affected vines. Healthy planting material from disease free mother plants and seed or cutting treatment reduce the carry over of disease. Since fruit is picked often, respect the pre harvest interval for any spray. Confirm the diagnosis and current recommendations with your KVK.
