For borer control in bean cultivation, spraying should follow the principle of focusing on the buds, spraying during the flowering stage to kill the larvae inside the flower buds. The best time to spray is on a sunny morning between 8 and 10 a.m. when the buds are open. After the flowers fade, when the pods are more than 10 cm long, spray once to kill newly hatched larvae and young larvae that have bored into the young pods. For the pesticide, you can choose Kongfu at 1500 times dilution, or abamectin at 1500 times dilution as a spray, or 4.5% Abamectin EC at 1000-2000 times dilution, or 25% Anleite EC at 1500-2000 times dilution, or 2.5% Ruining EC at 2000 times dilution, or 40% Nongsite EC at 1500-2000 times dilution, or 44% Sukai EC at 2000-3000 times dilution.
