Characteristics and control of tomato bud blight

The scientific name of tomato is tomato. Everyone must have eaten it. Tomatoes can be used as both vegetables and fruits. Growing tomatoes is relatively simple, but it may be more difficult to manage, because poor management will lead to a variety of diseases and insect pests, such as bud blight. Bud blight mainly occurs in high temperature and dry weather, which causes cracks in the plant and seriously nourishes the growth of the plant. Next, let's introduce the characteristics and control methods of bud blight. Let's take a look.

1. Characteristics of the disease

Sprout blight is a physiological disease of tomato, which mainly occurs in the environment of high temperature and drought in summer and autumn, mainly due to lack of timely ventilation. As a result, the buds die due to high temperature, and the rhizomes produce various types of cracks. The occurrence of bud blight is mainly in the position of 2-3 ears of the plant, and there is a transverse crack or "X" shape in the axillary bud, which has a great effect on the nutrient absorption of the plant.

2. Prevention and control methods

Spraying new high fat membrane

New high-fat film can enhance the ability of soil water conservation, reduce the rate of water evaporation in soil and seedlings, end the slow seedling stage ahead of time, and reduce the incidence of various diseases and insect pests. Therefore, we should spray new high-fat film in time after sowing to reduce soil water loss, which can effectively control bud blight and reduce the incidence of bud blight.

Ventilation and watering

In case of hot and dry weather, it is necessary to do a good job of ventilation in time, reduce the temperature in the greenhouse and keep the temperature in the greenhouse below 35 degrees. To do a good job of shading measures, sunshade nets and other equipment can be set at the top of the greenhouse to reduce the direct sunlight and reduce the light intensity. To prevent heat damage to the plant, timely watering, but pay attention to the watering mode, do not flood irrigation, dripping water to the leaf surface can effectively cool down and provide water demand.

Reasonable topdressing

Topdressing is a necessary work for growing tomatoes. We should pay attention to the application of trace elements such as boron and zinc to provide comprehensive nutrition for plant growth. In the process of growth, proper ploughing and watering should be carried out according to the growth situation, so as to prevent the growth of the main shoot and promote the differentiation of flower buds. Proper spraying of Zhuangtiling during flowering and fruiting period can increase pollination and fertilization rate, enhance fruit resistance and reduce the incidence of disease.

Cultivate new spike

When it is found that a plant has bud blight, we should cultivate new ears in time and cut off long branches, over-dense branches and other branches that affect plant growth. Then spray an appropriate amount of new high-fat membrane to reduce the invasion of bacteria and retain at least one strong inflorescence to prevent a serious decline in yield.

The above is a brief introduction to the symptoms and control methods of tomato bud blight. Blight is not a disease caused by bacteria, but it will cause other diseases and pose a more serious threat to the growth of tomatoes. And after the onset of treatment is more difficult, so we still have to do a good job in daily management, strengthen prevention. That's all for today's introduction.
