How to prevent and control turf brown spot

Turf brown spot is a fungal disease caused by Rhizoctonia solani, one of the most widely distributed diseases in all turf diseases, and can harm a variety of turf. It mainly causes the large area of â€‹â€‹turfgrass to die, which greatly reduces the ornamental value and use value of the lawn.

Control methods: 1. Reasonable irrigation, avoid flood irrigation, improve the drainage of the lawn, and remove the dew on the blades of the lawn grass in the early morning. 2. Remove the thick layer of hay and transport the cut grass in time to keep the lawn clean. For over-tight lawns, it is necessary to punch and ventilate in time. 3, reasonable fertilization, especially in the summer when the high temperature comes, try to apply less or no nitrogen fertilizer, can apply a small amount of phosphorus and potassium fertilizer to enhance the disease resistance of turfgrass. 4. Disinfect the seeds and soil before sowing. In the early stage of the disease, use the drugs such as thiophanate-methyl, chlorothalonil, mancozeb, and carbendazim. If the control is late, the drug must be increased. Concentration, and the effect will decrease. It is especially recommended to use the bactericide herbicide spot of Qilin New Plant Protection for spray control.
