worth collecting! Don't be afraid of tomato wilting, find the right cause to cure it!

When tomato is planted, plants often appear wilting, which may even cause root rot and affect other plants
.
In fact, there are different reasons for tomato plant wilting.
There are pathological wilting and physiological wilting.
Water shortage and high temperature can also cause plant wilting.
Therefore, the cause of wilting should be correctly judged and corresponding measures should be taken during control
.
1.
Physiological wilting 1.
Water shortage The wilting condition of plants caused by lack of water will be relieved after watering
.
However, if the water temperature is low during watering and the surface temperature is high, it will cause damage to the capillary roots and cause wilting due to insufficient water absorption
.
2.
High temperature and high temperature wilting occurs mostly in greenhouses, mainly because the air in the greenhouse is not circulated.
When the temperature rises, if the air is not released in time, the humidity in the greenhouse will be too high, causing the tomato plants to wilt
.
3.
Fertilizer damage Unreasonable fertilization can also cause plants to wilt.
If too much is applied at one time, the salt concentration around the root system will be too high, the capillary roots will be injured, and the symptoms of plant wilting will appear
.
2.
Pathological wilting 1.
Bacterial wilt, wilting, and flowering, begin to appear at the beginning of the fruiting stage, and the peak of the tomato fruit is the peak of the disease.
When the bacteria invade the plant, they will multiply in the vascular bundle and block the duct, making the entire duct lose its ability to transport water and fertilizer.
, Causing plants to wither and die
.
In rainy days or sunny storms, the disease will aggravate
.
2.
Bacterial Pulmonary Necrosis Wilting This disease is a bacterial disease that mostly occurs in the green fruit stage of tomato
.
It can be spread through rain and agricultural operations, affecting other plants
.
If it is continuous cropping, poor drainage and excessive nitrogen fertilizer, the disease will be aggravated
.
3.
Root rot wilt Root rot wilt is a disease caused by Phytophthora
.
When Phytophthora invades, a black spot will appear on the bottom of the stem, which will cause the water to not be transported to the upper part of the plant and cause wilting
.
4.
Rhizoma wilt This disease is an important disease in the tomato seedling stage
.
It often occurs in low temperature and high humidity, when the plant is dry, the roots are discolored and rotted
.
5.
Fusarium wilt Fusarium wilt, also known as wilt disease, is also a fungal disease, which usually occurs during the flowering and fruiting period, and the disease process is slow
.
Often co-occurring with bacterial wilt, it is a soil-borne vascular disease that is difficult to control
.
3.
Comprehensive prevention and control measures 1.
Implement crop rotation and stubble replacement.
Implement crop rotation and stubble replacement to avoid planting together with vegetables belonging to the Solanaceae family.
Continuous cropping with non-Solanaceae vegetables must also be separated for at least 2-3 years, which can reduce soil The accumulation of bacteria and pathogenic fungi in the plant can reduce plant disease
.
2.
The use strong selection of resistant varieties of tomato varieties with strong resistance cultivation, such Zheza 204, No.
1 powder against Penicillium, Gan 2 tomatoes, hair powder 802, No.
4 and the like in the vegetables
.
3.
Strengthen the cultivation management.
Use deep plowing to plant tomatoes, and try to avoid high temperature seasons when planting
.
Control the fertilizer and water, and do not water too much at one time to prevent root rot from affecting the normal growth of the plant
.
When watering in hot weather, you should choose in the evening or early morning
.
Apply fully decomposed organic fertilizer, and drain the field water in time after rain to prevent roots from soaking
.
Try to avoid trimming branches on rainy days
.
Grafted seedlings can be used in areas where diseases and insects are common, and disease-resistant rootstocks can be used to graft seedlings to prevent tomato plants from smelling
.
4.
Pesticide control: According to different pests and diseases, timely mix pesticides to prevent plants from wilting.
If wilting plants appear, they must be immediately pulled out and burned out of the field to prevent infection
.
