Diseases of natural pastures are from the spring to the autumn. They are usually caused by the presence of organic matter in the pastures. Therefore, it is first and foremost to remove organic matter from pastures. In summer, the environment is hot and humid, and many species are prone to breeding. Most of the diseases are caused by plant parasitic fungi. These fungi are attached to the soil, dead leaves, and decayed grass roots. Once the temperature is right, the bacteria may become active and multiply. Therefore, the natural grassland should be selected from the seeds. Initially, in the process of grass bed construction, the management period of grass seedling growth should be controlled scientifically such as the amount of fertilization, the time of fertilization, the type of fertilizer, the time of watering, the time of cutting, and the size of the crop. Errors in one link will create conditions for the occurrence of diseases. For example, cutting grass and removing grass from the field will be a harm.
The common diseases and prevention methods can be seen in the table below.
Common lawn disease occurrence and prevention methods
Disease name | Time | Occurrence conditions | Control methods | Crop Protection Act |
Brown spot | May to September | High temperature, moist | Use LDP or LDP+Fert | Improve drainage, deep watering |
Money spot disease | May to October | High temperature growth at 15~28°C | Use LDP or LDP+Fert | Inhibition of formation of subtilis layer, deep watering |
Fusarium | June to September | High temperature and humidity | Improve soil aeration and reduce weed layer | |
Leaf spot | Early summer and autumn | Cold and wet and cloudy | LDP or LDP+Fert | Reduce shading, improve soil aeration and drainage |
Rust | May to June | 20~25°C light and temperature | LDP or LDP+Fert | Recover scraps |
powdery mildew | March to October | Poor ventilation, air humidity | Improve air circulation and light transmission conditions | |
Spring spot disease | March to May | Windy drought | Last year LDP or LDP+Fert | Drug fight in the fall of last year |
Snow mold | Early autumn and late autumn | Wet, -5°C~5°C | LDP or LDP+Fert | Improve soil aeration and drainage, remove forage layer |
Ringworm disease | Any period | High organic content, moist | Remove organic residue and recycle residue |
Note: LDP - lawn disease control agent;
Fert—fertilizer.
