How to prevent the disease of pepper

Capsicum stripe virus disease, pepper stripe virus disease is mainly based on prevention, and its methods mainly start from the following aspects: First, soaking seeds with trisodium phosphate solution. Before sowing, the seeds are immersed in water at 25-30 ° C for 3 to 4 hours, and then the seeds are placed in 10% trisodium phosphate (ie, sodium trisphosphate and 9 water) for 20 minutes. After washing the seeds, seeding or germination can be used to passivate the virus. The second is pest control. Viral diseases are transmitted through poisonous juices, and some poisonous pests are the source of infections that cause the virus to occur. Therefore, it is necessary to prevent the spread of viruses such as aphids and whitefly in the management. At the time of re-cultivation or after planting, a 30-mesh insect net is installed to prevent the invasion of poisonous pests. Then pay attention to the operation of farming, and prevent humans from spreading the virus.

Capsicum blight, dead trees, rotten trees, rotten stems occur. In the seedling stage and the adult stage, the disease can occur, which is harmful to the stem and leaf fruit. At the seedling stage, the base of the stem was dark green water-soaked soft rot or tripped, that is, the seedling stage collapsed; some of the stems were dark brown, the seedlings withered and died; the leaves were infected, the lesions were round or nearly round, and the edges were Yellow-green, dark brown in the middle; fruit infection begins in the fruit bud, the first dark green water-immersed plaque, rapidly browning soft rot, the surface grows white mildew layer, and after drying, brown brown fruit is formed, which remains on the branch. Stems and shoots are infected, the lesions are initially water-soaked, and then there are brown or dark brown streaks around the epidermis, and the branches below the disease are rapidly wilting. This disease is prone to morbidity when it is severely ill, and the more watering, the more severe the disease. Prevention and treatment methods: First, prevent in advance, before planting, use 5 to 6 kg of dixon or Ethylene-phosphorus-aluminum-zinc per acre to mix in the soil and disinfect the soil. Then the roots. If the plant is found to be wilting, the base of the stem is black in water, and it can be restored sooner or later, and the tree is dead after several days. After the disease is discovered, it should be watered or not watered. You can use Pulik and a copper under the spray to grout the roots, each plant is rooted with 0.5 kg, once every 7 days, for 2 consecutive times, can not be missed.
