Pepper root rot is a soil-borne disease caused by fungi and is a common disease that occurs on peppers. This disease is distributed in all parts of our country and occurs widely. It can lead to stunted development of pepper plants and even die. It obviously affects the quality and yield of peppers, and causes certain economic losses to pepper production. So how to treat pepper root rot?What kind of medicine is used?
The pathogenesis of pepper root rot is mainly due to the accumulation of pathogenic bacteria in the soil and suitable environmental conditions. Pathogens can overwinter in the soil and survive for a long time, and when the environmental conditions are suitable, they begin to multiply and infect the roots of pepper plants, leading to the occurrence of diseases. In addition, factors such as excessive soil moisture, poor drainage, and improper fertilization may also promote the occurrence of pepper root rot.
1.The prevention and control of pepper root rot should be reasonably managed in the field, and pepper varieties with strong disease resistance should be selected, and timely drainage, ventilation and ventilation should be avoided to avoid excessive humidity and breeding of pathogens. At the same time, soil disinfection should be carried out regularly to remove diseased residues and reduce the accumulation of pathogenic bacteria. In the growth period of pepper, fruit Luohan + sodium nitrate naphthalene acetic acid can be used to promote the nutrient absorption of pepper and enhance disease resistance.
2.In the early stage of the disease, an appropriate amount of methyl tobuzin, carbendazim and other agents can be used for root irrigation, irrigating once every 7-10 days, and irrigating 2-3 times continuously. In addition, it can also be controlled by biological fertilizers or biological pesticides.
In conclusion, pepper root rot is a serious pepper disease that can cause irreparable damage if left unchecked. However, as long as we take reasonable prevention and control methods, we can effectively control its occurrence and spread. In production practice, we should pay attention to the combination of multiple methods to improve the control effect, ensure the normal growth and development of pepper plants, and bring benefits to growers.
