Pepper is an important vegetable in our province. In recent years, with the continuous expansion of the protected area, the root disease has become more and more serious, which has become a prominent problem in the production of pepper. There are two main types of root rot and disease in pepper root disease. Symptoms Differences The disease mainly affects pepper stems, leaves and fruits. In the initial onset, the stem produces water-immersed lesions, causing the seedlings to collapse, the base of the stem is dark green or black, and the upper lesion is initially water-stained, followed by brown or black streaks, and the black spots on the stems at the tillers are the most Commonly, the branches above the disease department are rapidly wilting. The leaf spot is round or nearly round, with a diameter of 2 to 3 cm. The center of the lesion is dark brown and the edge is yellow-green. The fruit is damaged from the pedicle, producing a water-stained dark green lesion. Afterwards, the lesion becomes brown and soft, and a white mold layer grows when wet. Root rot mainly damages the roots and stem base. The epidermis is light brown to dark brown, and the epidermis is brittle, revealing the xylem of dark dry rot. Generally, the disease begins after colonization. After the result, the shoots of the diseased plants are wilting, and return to normal in the evening until the next morning. After a few days, the whole tree is dead.
Prevention and control methods Soil roots diseases should be based on prevention, and measures taken after the onset are often half the battle.
1. Seed soaking with 1% sodium hypochlorite solution for 5 to 10 minutes, germination and sowing after washing with water.
2. Strengthen field management, prevent water accumulation in the field and flood irrigation, select resistant varieties and increase organic fertilizer.
3. Growth period drug control. Before the colonization, the plots of the disease will be filled with 500-800 times of Radomire (or Kelu or anti-drug or Pulk or Anke or E-phosphorus), 500 ml per hole, and then rooted at the beginning of the disease. The root rot occurred in the place where the colonization was preceded by carbendazim or methyl thiophanate or Dakok or chlorothalonil 500 times. The roots were irrigated with these two liquids for 2 to 3 times. When the medicament is controlled, different medicaments should be rotated and applied. Do not apply a single agent multiple times to avoid the resistance of the pathogen and reduce the control effect.
