Adult worms lay eggs on the young leaves of the plants. After 5-7 days, the hatched larvae are plunged into the pods to feed the beans. After the larvae above 3 years old are drilled in the pod, it is difficult to kill them by spraying the medicament. Therefore, the prevention and control of the insects should strengthen the management of fertilizer and water, ensure that the growth is neat, and the flowering and pod-forming period is relatively concentrated, so as to eliminate the insects in a critical period.
The prevention and control of the bean heartworm should adhere to the principle of “regarding buds as the mainstay†and spray the larvae in the flower buds during the flowering period. The spraying time is best at 8:10 am on a sunny day (when the flower garden is open). After the flowering of the flower, the pod grows to a length of more than 10 centimeters and sprays once, which can kill the young larvae that have hatched and invaded the young pods. The medicine can be selected from Kung Fu 1500 times liquid or avermectin 1500 times liquid.
