Symptoms and Characteristics of Tomato Bud Blight and the Latest Control Methods
The scientific name of tomato is Solanum lycopersicum, and everyone has certainly eaten it; tomatoes can be used both as a vegetable and as a fruit. Growing tomatoes is relatively simple, but managing them can be rather difficult, because poor management can lead to various pests and diseases, and bud blight is one of them. Bud blight mainly occurs in hot, dry weather, causing cracks in the plant and severely affecting the plant's growth. Below, let me introduce the characteristics and control methods of bud blight. Let's take a look!
1. Disease characteristics
Bud blight is a physiological disease of tomatoes, mainly occurring in summer and autumn under high temperatures and dry conditions; the main cause is failure to ventilate in time. This causes the young buds to die from excessively high temperatures, and various types of cracks form on the stems. Bud blight mainly occurs at the position of the 2nd-3rd fruit trusses 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 preservation capacity, reduce the evaporation rate of water from the soil and within the seedlings, end the seedling revival 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 soil moisture loss, which can effectively 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 the temperature inside below 35°C. Certain shading measures should be taken; shade nets and other 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 in time, but pay attention to the watering method: do not use flood irrigation; dripping water onto the leaf surface can effectively cool the plants and provide the required water.
Rational topdressing
Topdressing is essential work in tomato cultivation. 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 period, appropriately spraying Zhuangdiling can increase the pollination and fertilization rate, enhance the resistance of the fruit, and lower the incidence of the disease.
Cultivating new trusses
When we find plants affected by bud blight, we should cultivate new trusses in time and prune away branches that affect plant growth, such as excessive growth shoots and overly dense branches. Then spray an appropriate amount of New High-Fat Film to reduce the invasion of pathogens, and at least one inflorescence with strong growth should be retained to prevent a severe 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, making the growth of tomatoes face even more serious threats. Moreover, treatment after onset 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; this article is for reference only, and we hope it can help everyone.
