Carrot bacterial soft rot is mainly harmful to the fleshy roots of the underground. It can occur in the field or during storage. In the field, the stems and leaves of the upper part of the diseased plant become yellow and wilted. The root is infected, initially wet and rotted, and then enlarged, the shape of the lesion is uncertain, the periphery is obvious or not obvious, the fleshy root tissue softens, it is gray-brown, the rot juice overflows, and has an odor. [Pathogenesis]: The pathogen is surviving in the root tissue or in the soil left by the diseased body, or in the unfertilized soil and fertilizer, becoming the initial infection source of the disease. The pathogen can be sputtered by small insects and underground pests or irrigation water and rainwater, and invades from roots and stems or stomata and water holes in the shoot. In the southern vegetable region, the field hosts exist all year round, and the germs can spread and spread without obvious wintering. Usually the rainy year or the hot and humid weather is easy to induce the disease. The underground pests are seriously affected by the field. [Control measures]: ( 1) It is advisable to implement rotation with onion and garlic vegetables and rice in seriously ill areas or fields. (2) It is difficult to implement the rotation of the land should be 667 square meters to increase the application of lime 100-150kg. Deeply turn the soil or water to soak the fields for a certain period of time before drying. Planted with sorghum. Apply compost made from organic active fertilizer or enzyme bacteria. Timely control of underground pests. Conditional herbicide weeding to minimize wounds. (3) Strengthen the inspection, drain the water in time after the rain, and find that the diseased plant is destroyed at any time, and remove the lime or drench the diseased hole. (4) Lightly digging and harvesting at the time of harvest, try to reduce the wound, and take it for half a day after harvesting. After entering the sputum, strictly control the temperature below 10 °C and the relative humidity below 80%, which can reduce the incidence.
