Pests and diseases rarely occur during windbreak development and only occur in individual years. We must do a good job of investigation and take care of it. 1. Powdery mildew occurs in summer and autumn. The leaves of the victim were white-powdered spots on both sides, and later they gradually grew small black spots (bacterial capsule shells). In severe cases, the leaves fell off early. The pathogenic fungus is a fungus belonging to the genus Aspergillus subsplenium of the univial powdery mildew. The onset of pathogenic bacteria overwintered on the body of the disease. Ascoma spores cause initial infection, and conidia produced on diseased plants are transmitted by wind and rain, causing repeated infections, and the diseases are severe when the weather is dry. One of the prevention and control measures is to remove the diseased bodies before the winter, centralize the destruction, and reduce the sources of field infestation. The second is the spraying of Baume degree lime sulfur, or 15% triadimefon 800 times, or 50% carbendazim 1000 times. Every 7-10 days with one of the agents to control, spray a total of 2-3 times. 2. Root rot occurs in high temperatures and rainy seasons. After being killed, the roots rot and the leaves wilted and turn yellow. Control methods At the beginning, the diseased plants were removed and lime powder was used to disinfect the caves; 70% chloronitrobenzene powder was also used to mix the roots (1:10) with roots and cover soil. 3, Huang Feidie Huang Feidie, also known as the Anise season butterfly, larvae eat leaves. The prevention and control method was used to kill 90% trichlorfon 800 times or 80% dichlorvos 1000 times.
