First, the symptoms of infection in early mold mildew, thicker or wider leaves, leaves do not change color. When the onset of the disease is severe, small patches of 1 to 10 cm in diameter appear on the lawn. The roots of the affected plants are yellow and short and can easily be pulled up. Under wet conditions, a white frost-like mold layer appears on susceptible leaves. Second, the incidence of disease onset temperature of 15 °C ~ 20 °C, so the disease usually occurs in late spring and autumn, and the first place in poor drainage occurs. High temperature, rain, low-lying water and flood irrigation are all conducive to disease epidemics. Third, the prevention and control methods (a) to ensure good drainage conditions to ensure that irrigation or rainfall can eliminate the excessive moisture on the lawn surface. (2) Reasonable fertilization, avoid partial nitrogenous fertilizer, increase phosphorus and potash fertilizer. (c) The diseased plant was found to be removed in a timely manner. (D) With 0.2% ~ 0.3% of Rhizoctonia, B-aluminum, anti-virus and other agents for seed dressing, or with the above-mentioned agent 1500 ~ 2000 times liquid spray, can achieve better control effect.

he Fluorine-Containing Phenol series product is toxic and irritating, it should be avoided absorbed into the body through the skin. And not allow to store with strong oxidant, alkali, hydrochloric acid and acid anhydride , Store with flammable liquid or solid,must be away from heat and open flames,it should be stored in a cool dry place. Most of the fluorine-Containing Phenol products are stable at room temperature and pressure, but avoid contact with the oxide. In the air it is easily oxidized color.
Manufacture and storage of fluorine-containing phenol series should be carried out in a well ventilated place. Wear appropriate protective equipment and prevent dust from spreading. Wash hands and face thoroughly after handling.
Most of the fluorine-containing phenol series of products can be sublimated. It can cause severe skin burns and eye damage.
So save the fluorine-containing phenol series in sealed containers must be stored in a cool, dark place. It must be stored locked. In the event of a fire extinguishing agent is suitable dry powder, alcohol-resistant foam, water spray, carbon dioxide.
