Causes and Control methods of rotten Tomato

Tomato is our common fruit and vegetable, and its sweet and sour taste is loved by many people. with the increase of its market demand, its planting area is increasing year by year. Many people will inevitably encounter a lot of problems when planting, among which many growers are deeply harmed by rotten tomatoes. So what's going on? How to prevent and cure it? Let's take a look at the causes and control methods of rotten tomatoes.

Reason 1: improper watering and high soil moisture

Although tomatoes need a lot of water during their growth, they should not be watered too much each time, just keep the soil moist. Too much watering leads to stagnant water, resulting in low ground temperature and poor soil permeability, resulting in rotting roots and rotting poles.

Prevention and control methods: choose loose and well-drained soil when planting, and the water requirements for tomatoes are different in each growth period, so watering scientifically, watering frequently, but not too much each time. If the watering is too much or the soil moisture is high, the illumination time of tomatoes can be increased and the excess water can be evaporated by leaf transpiration.

Reason 2: low temperature

The best temperature for tomato growth is 20-30 degrees. When the temperature is below 13 degrees, its growth will slow down. If it is below 13 degrees for a long time, its growth and development will be poor. Below 6 degrees, the plant will be damaged by freezing injury, resulting in rotting rod phenomenon.

Prevention and control methods: this phenomenon mainly occurs in the cold areas of the north and rarely in the south. If the temperature is too low, you can use the greenhouse technology to keep warm and keep the temperature above 15 degrees.

Reason 3: large temperature difference between day and night

The suitable temperature for tomato growth is between 25-28 degrees during the day and 16-20 degrees at night. When the temperature difference between day and night is large, it will damage the roots and cause the plant to wilt and rot.

Control methods: this situation mainly occurs in the southern region in late spring and early summer, when the temperature is high during the day and low at night, which can easily lead to plant problems. If the temperature is too high during the day, it can be used for sunshade, and at night, it can be artificially heated or planted in the greenhouse.

Cause 4: disease

There is no disinfection of seeds and soil before planting, or long-term stubble, resulting in the proliferation of bacteria in the soil, these bacteria are easy to lead to tomato bacterial wilt, Fusarium wilt and other diseases, these diseases will lead to plant rot.

Prevention and treatment methods: disinfect the seeds and soil before planting, remove and burn the diseased plants in time, and sprinkle quicklime or plant ash on the soil to disinfect and sterilize, and apply chemicals for treatment.

The above is the introduction of the reasons and prevention methods of tomato rotten pole brought to you by pro-agricultural network. I believe we also have some understanding of the cause of tomato rotten pole, and pro-agricultural network also brings relevant prevention and control methods for you. I hope I can help you.
