Tomato tendon rot disease has generally occurred in recent years, seriously affecting the yield and quality of tomato. If it is not prevented in time, it will cause great economic losses to vegetable growers. First, the symptoms There are two types of tendon rot. The first is browning. During the fruit enlargement period, local browning occurred on the fruit surface. The fruit surface was uneven and the fruit was dark brown or had necrotic spots. The vascular bundle in the pericarp of the cut fruit showed brownish necrosis, hardened fruit, or browned pulp. Loss of commodity value. The second is the white variant. Mainly occurs in the ripe fruit turn red period, the disease is uneven coloring of the fruit, the disease has a wax-like luster, cut open fruit can be seen in the fruit was "squeaky" shape, the vascular tissue of the pulp was dark brown, the incidence of light changes The brown part does not turn red, the flesh hardens, and the quality is poor, pale and tasteless. The heavier fruit flesh vascular bundles are all dark brown and the fruit forms a cavity. The disease is generally not easy to see symptoms from the stem and leaf performance. Second, the reasons Tomatoes tend to rotten fruit, generally occurs in the fruit enlargement and maturation period, mainly due to poor environmental conditions, improper cultivation measures, especially excessive nitrogen fertilizer, and potassium and organic fertilizer is insufficient, lack of light, high temperature and humidity, resulting in plant carbon and nitrogen ratio Disorder. In particular, sunny days after a sunny day, such diseases can easily occur. In addition, the damage of plants caused by virus diseases may also aggravate the occurrence of rot and rot, or form some stiff blocks on the surface of the fruit, which seriously affect the fruit quality. In particular, heavy scorpion, partial nitrogen fertilization, flood irrigation, and soil compaction occur. Whether it is cultivated in the spring or in the autumn, tomato rot and rot may occur. Third, preventive measures There are many reasons that cause tortilla rot and fruit decay. Prevention and treatment of tendon rot must start from these evoked causes and take preventive measures. 1. Select the appropriate variety and strictly control the virus disease. For different tomato varieties, the occurrence of loosing and rotting fruit differ greatly, and tomato varieties resistant to viral diseases should be selected as far as possible. In the cultivation and management should be timely and effective prevention and treatment of viral diseases. Pay attention to reasonable rotation to alleviate the imbalance of soil nutrients. 2. Strengthen fertilizer and water management. Increase the use of adequately decomposed organic fertilizers, especially bio-organic fertilizers, to achieve balanced fertilization and prohibit excessive application of ammonium nitrogen fertilizers. After fruit set, multiple composite micronutrients (boron, calcium, iron) began to be applied every 15 days for 2-3 consecutive times. Keep the soil moisture right, drain it in time after the rain. 3. Use 40% plant virus soluble powder 1000 times liquid, in the period of planting seedlings, especially after the beginning of the results, can significantly reduce the occurrence of rot and rot, generally should be used once 7-10 days, continuous 3-4 Times. In the low temperature, weak light when spraying potassium dihydrogen phosphate. Promote the use of multiple compound liquid fertilizers, and other foliar fertilizers such as love more income, once every 7 days, 3-4 times in a row.
