The pepper is simple to cultivate, strong in resistance, high in yield, and the cultivation area is increasing year by year. However, the hazards of pests and diseases have caused a large loss of yield, especially the pests are more serious. First, the small tiger 1. Hazard characteristics. The larvae bite off the stems of the pepper seedlings near the ground, causing the whole plant to die, causing serious damage and even destroying the seedlings. 2, prevention and treatment methods - trap and control.

In severe cases, the fruit rate is over 30%. 2, prevention and treatment methods - In the main production areas of the seed production, if the perennial tobacco worms are seriously endangered, the traps can be planted nearby to trap the overwintering adults and concentrate on spawning, which is easy to eliminate. - Remove the fruits that are foraged in time to prevent the larvae from turning to fruit. - Chemical control. In the first and middle of June, the first generation larvae were controlled, and the second and third generation larvae were controlled from mid-July to mid-August. In September and October, the prevention and control of the fourth and fifth generation larvae were determined according to the development of the insects and the damage. 90% crystal trichlorfon 800 times solution, 10% permethrin 3000 times solution, 25% cypermethrin 4000 times solution, 20% cypermethrin 3000 times solution or 2.5% enemy kill 4000~ 6000 times liquid spray.
