In summer, it is hot and rainy. Tianying pepper grows in such an environment and is prone to pests and diseases. The main diseases are: viral diseases, Phytophthora root rot, anthracnose, soft rot and other diseases. Insects include: red spider, beet armyworm and cotton bollworm. These pests and diseases are a major obstacle to the high yield of Tianyingjiao.
1, viral disease. It is characterized by dwarfing of plants, dark green leaves, shrinkage, fern-like leaves, or leaves with chlorosis and yellowing of leaves; fruit has concave brown streaks. In the early stage, timely control of aphids can be sprayed with 1500 times of 10% imidacloprid. It was found that the condition can be sprayed with 20% virus A wettable powder 400 times or 1.5% phytopathogenic emulsion 500 times.
2, epidemic disease: when the leaf is susceptible to disease, it produces green round lesions with no obvious edges. When the humidity is high, the lesions expand rapidly, causing soft rot of the leaves. The stems and branches are ill, and there are brown streaks around the epidermis. The branches above the disease are quickly withered and die. The base of the stem often causes brown soft rot, sometimes covered with a layer of white frost. The fruit is sick, starting from the pedicle, forming dark green water-stained, irregular shaped lesions, which quickly spread to the whole fruit, and some flesh and seeds also change color. When the humidity is large, the fruit grows sparse white. Flocculent layer. 75% chlorothalonil wettable powder 600 times, 64% anti-virus WP WP 400 times, 72% gram dew 800 times, 70% mancozeb 400 times spray
2, anthrax. The surface of the fruit is immersed in a yellow-brown lesion on the surface of the fruit. It grows round or irregular, with depressions, a slightly raised concentric pattern, and a reddish-brown edge. In the early stage of the disease, spray 3000 times of Lectra, 600% of chlorothalonil 600 times, 70% of methyl thiophanate 400 times, 80% of anthrax fumei 600-800 times and so on. Spray once every 7-10 days for 2-3 times.
3, scab disease. Also known as bacterial spot disease. The leaves are initially immersed in yellow-green spots and are irregular in shape, and the edges are dark brown. The edge of the leaf and the tip of the leaf turn yellow and dry and fall off. On the fruit, the lesion becomes a round or oblong black scab-like lesion after a small black spot, and there is a crack at the edge of the lesion. In the early stage of the disease, it can be sprayed with 500 times of 10,000 times of liquid, 72% of agricultural streptomycin or 3000-4000 times of neomycin.
4, soft rot. Mainly harmful to the fruit. At first, the water-soaked dark green lesions on the fruit gradually turn brown, and then the fruit rots and smells. When the prevention and treatment, 500 times of liquid can be used, spray once every 7-10 days, even spray 2-3 times, focusing on the umbilical part of the fruit.
5, cotton bollworm, beet armyworm, cabbage caterpillar: 100 strains of insects up to 10 timely prevention and treatment. 52.25% agricultural land 1000 times, beta-cypermethrin and phoxim 1:1 mixed 1000 times, sprayed.
