Symptoms and Control Methods of Tomato Bud Blight
The scientific name of the tomato is Solanum lycopersicum, and everyone has surely eaten it; the tomato can serve as both a vegetable and a fruit. Growing tomatoes is relatively simple, but managing them can be rather difficult, because poor management leads to all kinds of pests and diseases, and bud blight is one of them. Bud blight mainly occurs in hot, dry weather, causing cracks in the plant and seriously affecting its growth. Below is an introduction to the characteristics and control methods of bud blight. Let's take a look!
1. Disease characteristics
Bud blight is a physiological disease of tomatoes, occurring mainly in the high-temperature and dry conditions of summer and autumn. The main cause is failure to ventilate in time, which causes the young buds to die from excessively high temperatures and produces various types of cracks on the roots and stems. Bud blight occurs mainly at the position of the 2nd-3rd fruit clusters of the plant, where a horizontal crack or an “X” shape appears at the axillary buds, greatly affecting the plant's nutrient uptake.
2. Control methods
Spraying New High-Fat Film
New High-Fat Film can enhance the soil's water retention and moisture-conservation capacity, reduce the evaporation rate of water from the soil and within the seedlings, end the seedling-recovery period early, and lower the incidence of various pests and diseases. Therefore, after sowing we should spray New High-Fat Film in time to reduce water loss from the soil, which can effectively prevent and control bud blight and lower its incidence.
Ventilation and watering
In hot, dry weather, ventilation work should be done in time to lower the temperature inside the greenhouse, keeping it below 35 degrees. Take certain shading measures; shade nets and similar equipment can be set up at the top of the greenhouse to reduce direct sunlight and lower light intensity. To prevent heat damage to the plants, water them in time, but pay attention to the watering method: do not flood-irrigate; dripping water on the leaves can effectively cool them and provide the needed water.
Reasonable topdressing
Topdressing is an essential task in growing tomatoes. We should pay attention to the application of fertilizers with trace elements such as boron and zinc to provide comprehensive nutrition for plant growth. During the growth process, we should also carry out appropriate intertillage and watering according to the growth situation, to prevent excessive vegetative growth of the main shoot and promote flower bud differentiation. During the flowering and fruiting stage, appropriately spraying Zhuangdiling can increase the pollination and fertilization rate, enhance the fruit's resistance, and lower the incidence of the disease.
Cultivating new clusters
When we find plants affected by bud blight, we should cultivate new clusters in time and prune away water sprouts, overly dense branches and other branches that affect plant growth. Then spray an appropriate amount of New High-Fat Film to reduce the invasion of pathogens, and keep at least one relatively vigorous flower cluster to prevent a serious drop in yield.
The above is a brief introduction to the symptoms and control methods of tomato bud blight. Bud blight is not a disease caused by pathogens, but it can lead to other diseases, posing an even more serious threat to tomato growth. Moreover, once it occurs, treatment is relatively difficult, so in our daily work we should still do a good job of management and strengthen prevention. That is all for today's introduction.
