Root rot disease is a common pest and disease in the growth process of cockroaches, which will cause great harm to the growth of cockroaches. In order to prevent root rot, we must first understand the pathogenesis of root rot.
What is the pathogenesis of root rot disease?
Root rot is a soil-borne disease. It mainly nucleuses overwinter on diseased plants, and can also infect winter-stained diseased plants in soil and soil. The invasion of the pathogen from the root wound causes the occurrence of the disease. Different pathogens and different infestation methods make the disease's incubation period different. As the disease spreads, the unfavorable factors leading to the weakening of the tree in the middle and late stages can cause the disease to occur. The terrain is damp and low, and there is more water (ditch drainage). The root rot disease is common and the damage is serious. The plants that die from the disease are 3%-5% per year, causing great losses to the production of alfalfa. If found, it should be prevented in time.
