The medicament composition for preventing and treating gray mold of macadamia nuts of the present invention is composed of active ingredients with different action mechanisms, has obvious synergistic effect, has a good control effect on gray mold of macadamia nuts, can reduce the dosage and frequency of application, and reduce the Control costs, reduce the pressure of pesticides on the environment, and reduce pesticide residues.

Description

technical field [0001] The invention belongs to the technical field of research and development of new pesticides, and in particular relates to a medicament composition for preventing and treating gray mold of macadamia nuts. Background technique [0002] Macadamia nut, also known as macadamia nut, is a macadamia plant native to Australia. It not only has high economic value, but also has good nutritional value and medicinal value. It is known as the "king of dried fruits" . There are many diseases and insect pests in macadamia nuts, more than 30 kinds of diseases and more than 300 kinds of insects. The more serious diseases are blight, root rot, flower blight, anthracnose, canker and gray mold. Among them, gray mold damages the young leaves and inflorescence top parts of the macadamia tree body. Fine water-soaked spots appear on the newly drawn leaves after being damaged. As the disease progresses, the whole sick leaf turns black. A layer of gray-green powder grows, causi...
