Problems solved by technology

[0005] Cucumber root-knot nematode is a disease that has occurred seriously in recent years, especially in greenhouses where cucumbers have been planted year after year. Once the disease occurs, the loss is relatively serious, and the yield is generally reduced by 20-30%, or even no harvest, which seriously affects the production of cucumbers. Yield and quality, therefore, need to invent a kind of efficient, low toxicity and low residual cucumber root-knot nematode control medicament

Description

technical field [0001] The invention relates to the technical field of cucumber planting, in particular to an agent for preventing and treating root-knot nematode disease of cucumber with high efficiency, low toxicity and low residue. Background technique [0002] Cucumber root-knot nematode (Meloidogyne) is caused by root-knot nematode incognita and occurs on cucumber crops. It only harms the lateral roots and fibrous roots of cucumbers. If the fibrous roots or lateral roots are infected, it will produce root knots of different sizes. It is white at the beginning, the surface is smooth and firm, and the root knot turns yellowish brown and rots later. [0003] In recent years, the development of off-season cultivation methods has provided suitable temperature, humidity and nutritional conditions for the occurrence of root-knot nematodes, resulting in the accumulation of pathogenic nematodes in the soil. The incidence is on the rise. [0004] In addition to cucumbers, the d...
