Nowadays, all parts of the country are carrying out hot winter production. As one of the main varieties of winter seeds, pepper cultivation is very extensive. The main pest control points in its cultivation management are introduced as follows:
First, the seed disinfection: generally use pesticide soaking, seedling bed seedlings. Soaking seeds can be used with 0.01% of Tianfengsu emulsifiable concentrate and 50% of 70% red WP. It can be soaked for 12 hours, and then immersed for moisturizing and germination. The germination rate is about 70%. On the one hand, it can increase the germination rate, and strengthen the seedlings to promote roots; on the other hand, it can be used for seed disinfection to prevent seedling diseases.
Second, field management:
1. Management of seedling stage should be done before and after the incubation of the seedlings. Top dressing: using foliar spray of 0.01% of Tianfengsu emulsifiable concentrate and 5kg of potassium dihydrogen phosphate 1 and 15kg of water, it is beneficial to enhance photosynthesis, promote deep rooting, promote robust growth of plants, and enhance plant growth. Disease resistance.
2, flowering results management should be done in the flowering period of watering and fertilization and pruning, snoring, leaf picking, harvesting, etc., while using 0.01% Tianfengsu emulsifiable concentrate 5 ml plus 30 grams of urea against water 15 kg, Foliar spraying once every 10 days from the flowering stage can accelerate plant growth, promote its continuous flowering results, improve the rate of results, prevent falling flowers and fruit, and prolong the harvesting period. At the same time, the quality of the pepper is improved and the occurrence of the deformed fruit is reduced.
Third, pepper pest control:
1. Capsicum blight: Symptoms: The leaves, stems and fruits of the seedling stage and adult stage can be affected. Water-stained rot occurs at the base of the seedlings of the seedlings. The diseased part is dark green, and finally the body is collapsed or dead, and the affected plants are killed. Or the leaves on the branches are withered from top to bottom and are easy to fall off. Control method: spray with 600% of 64% Tianliang wettable powder or 500% of suspending agent 500 times. In order to improve the disease resistance of plants, it is necessary to control the nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, and spray 2500 times of 0.01% Tianfengsu emulsifiable concentrate.
2, the symptoms of capsicum anthracnose: mainly affected by mature fruit, the first water-stained yellow-brown round spot, the center is taupe, the edge is brown. The lesion is sunken, with a slightly raised concentric pattern, with small black spots on it. When wet, the surface of the lesion is covered with red sticky material. Control method: Implement a 3-year vegetable field rotation system to disinfect seeds, strengthen field management, and prevent high temperature and high humidity. Use chemical control, spray with 70% red sun wettable powder 1000 times.
3. Symptoms of pepper leaf blight: Both seedling stage and adult stage occur, mainly caused by leaf damage, and petiole or stem are sometimes sick. Leaves infected with small brown spots, rapidly expanding into round or irregular lesions, central grayish white, dark brown edges. In the later stage, the diseased leaves are easy to fall off, and the disease develops upward from the lower leaves of the plants. In severe cases, the whole leaves fall. Control method: 50% active suspending agent 500 times liquid or 70% red day wettable powder 1000 times or 64% Tianliang wettable powder 600 times liquid spray.
4, pepper line 螨 (common name) Symptoms: curling, yellowing, fallen leaves. Control method: It can be sprayed with 5% of 20% mites emulsifiable concentrate or 1000 times of 24% mulch.
5, cotton bollworm control method: can be used 4.5% green emulsified milk 1500 times, 24% Wanling water agent for the use of 75-100 ml of the preparation of milk or 20% of the insecticide emulsifiable 1500 times liquid spray.
First, the seed disinfection: generally use pesticide soaking, seedling bed seedlings. Soaking seeds can be used with 0.01% of Tianfengsu emulsifiable concentrate and 50% of 70% red WP.
