What to Do When Peppers Get Pests? A Complete Guide to Prevention and Control Methods
Peppers are a vegetable we often eat in our daily lives. Many friends who love spicy food have reached the point where no meal is complete without spice, which is truly beyond the reach of ordinary people. But what we are discussing here is how to deal with pest and disease problems that occur during the growth of peppers.
I. Prevention and Control of Common Pepper Pests
Common pepper pests include aphids, thrips, tea yellow mites, tobacco budworms, and cotton leafworms (Spodoptera litura). After pests appear on peppers, the pest species should be identified as early as possible so the right treatment can be applied. Pests such as aphids and thrips generally gather on tender leaves, stems, and flower buds, sucking sap and causing leaves to curl and turn yellow, while also transmitting viral diseases. When treating them, clear weeds from the field. Lay 0.5 m wide silver-gray plastic film around the vegetable plot, hang silver-gray film strips over the seedbed for repellency, then choose Weiyuan Biochemical 10% imidacloprid WP, Dingji 1000-1500 times solution, or Xinhhuikang 1000 times solution for spraying.
Tea yellow mites mainly feed as young mites on the sap of tender parts such as unopened leaves, buds, and flower buds. After damage, leaves become stiff and thickened, the leaf underside appears yellowish-brown and oil-stained, and leaf margins curl backward. Young stems twist or become bare-tipped, and flower buds become deformed. For prevention and control, use Chongmankexing 3000 times solution, 2% abamectin EC, or Xuanji 3000-4000 times solution, spraying once every 7-10 days, focusing on the leaf underside, tender stems, flower buds, and young fruit.
Tobacco budworms and cotton leafworms (Spodoptera litura) use their larvae to bore into and feed on pepper flower buds, fruit, leaves, and buds. Infested fruit rots, causing heavy fruit drop or bored fruit, and stems and leaves are lost, leading to reduced pepper yield. The main treatment is emamectin benzoate 1500 times solution or lambda-cyhalothrin 2000 times solution for good control results. Alternatively, spray 20% fenvalerate EC 2000-3000 times solution.
The above is some relevant knowledge about pepper pests. When small black insects appear on peppers, prevention and control must be carried out promptly, not delayed until fruit drop occurs. Although peppers are very tasty to eat, they must endure many diseases during growth and require careful care. The ones who work hardest are probably the farmer friends.
