Interplanting Pepper Fields Against Virus Disease

Right now in the hot and dry season, locusts, migratory locusts, and thrips are more important than in previous years. During the period of interplanting wheat and pepper, most locusts, migratory locusts, and other pests lived on wheat. When wheat is harvested, wheat is harvested. Aphids and migratory locusts fly on the peppers to inhale them, and the wheat virus is directly transmitted to the peppers. After experiencing wind and rain, airflow, and friction between branches and leaves, the virus disease is likely to occur greatly. Similarly, in the orchards, the peppers planted in the orchard are often densely planted, poorly ventilated and light-transmitting, and the interplanting peppers are denser, leading to incomplete prevention and control of some locusts and planthoppers after one or two applications.

Chick virus disease is also called mosaic disease. The four typical symptoms in the field are mosaicism, yellowing, necrosis, and malformation.

The mosaic leaves are the symptoms of yellow-green leaves or shades of leaves on the leaves. The leaf color is chlorotic, the leaves are shrinking, the leaves are slender, the plants are dwarf, and the fruits are yellow and green. Yellowing, that is, the diseased plant leaves are obviously yellow, dead leaves, resulting in shedding. Necrosis, that is, the diseased tissue of the plant becomes brown and necrotic, necrotic streak appears on the diseased leaf surface, and necrotic streak or ring spot appears on the diseased stem. Severe onset, causing fruit drop, and even cause the plant to die. The deformity, that is, the shades of the leaves, is thin and round, and the thickness of the posterior blade is linear, thickening, the plants are obviously dwarfed, the branches are increased, the plexus is produced, and the plants are deformed when they are severe. The same plant may have multiple symptoms concurrently, causing the plant to defoliate, drop flowers, drop fruit, and even cause the plant to die. In the prevention and control should master the following four points:

(a) Select resistant varieties, such as Jiajia 5th sweet pepper, Haifeng No. 1 sweet pepper, Shuangfeng sweet pepper, Shanghai bell pepper and Shanghai sweet pepper.

(b) Dealing with seeds before sowing. Seeds were collected from disease-free seedlings and disease-free seeds were selected. The introduction of commercial seeds to seed treatment before interplanting, can be soaked with 10% trisodium phosphate solution before sowing for 20 to 30 minutes, and then washed with liquid water after drying germination sowing.

(c) Strengthen interplanting field management. Timely planting, nurturing strong seedlings, and controlling maggots and fly hoppers on wheat and fruit trees before transplanting. Rational close planting, adequate base fertilizer, promote plant robustness, and improve disease resistance. Clean up the weeds in the field in time and spray them regularly. Do not just stare at the insects on the peppers. Instead, prevent the insects on the wheat and fruit trees in advance and reduce the virus source.

(D) Before the onset of disease or during the harvest period, step up the spraying of bactericidal agents (high concentration) 3000 times (10 to 20 grams per acre) and 20% of virus A WP (700 to 1000 times) (per acre 100-150 grams) spray prevention, spraying once every 7-10 days, even spraying 2 or 3 times, can reduce the incidence of captive field pepper virus disease and enhance plant resistance.
