Q: How can I prevent vegetable pests from damaging my crops?
A: According to experts from the provincial food office, it's essential to apply pesticides strategically based on the behavior and life cycle of the pests. For instance, the older larvae of the cabbage worm (*Spodoptera litura*) and the beet armyworm (*Spodoptera exigua*) tend to hide during the day, so it's best to spray them during the early morning or late afternoon when they are more active.
In addition, cowpeas bloom between 7 and 10 a.m., and their petals close shortly after. During this time, the young larvae of the bean pod borer are most active, feeding on the flowers that threaten the crop. To effectively control these pests, it’s recommended to apply pesticide before 9 a.m., when the flowers are still open and the larvae are more exposed.
By timing your pesticide applications properly, you can maximize effectiveness while minimizing unnecessary chemical use. It's also important to follow safety guidelines and use the correct dosage to protect both your crops and the environment. Regular monitoring of your plants will help you detect pest activity early, allowing for timely intervention.
