Apple spotted leaf disease, also known as brown streak disease, occurs in various fruit areas in my country. It mainly damages leaves, new shoots and fruits, causing early leaf fall of apples, causing tree weakness, reduced fruit yield and quality, and easy infection during storage. Pathogens cause rot. In orchards with serious disease, the rate of diseased leaves can reach 90%, and the rate of deciduous leaves can reach 80%, which seriously affects the yield and quality of fruit, as well as the vigor and flower bud differentiation of fruit trees. Therefore, the prevention and control of spotted leaf disease is the top priority in apple orchard disease management.

The occurrence and prevalence of    spot leaf fall are closely related to climate and species. High temperature, high humidity and rainy diseases are prone to occur, and the onset of drought diseases in spring is postponed; summer rainfall is heavy and humidity is heavy, and the disease is severe. Among apple cultivars, the Marshal line is susceptible to the disease, while the Fuji line and Jonah's disease are milder. In addition, the canopy canopy, poor ventilation and light transmission, weak tree vigor, low-lying terrain, high groundwater level, and tender branches and leaves are all prone to disease.

The key to prevention and control of spot leaf fall disease is to spray fungicides in time before or at the beginning of the disease (sporadic diseased leaves appear in the orchard). It is necessary to adhere to the mixed use of protective agents and systemic agents, and use fungicides with different mechanisms of action alternately. Commonly used in production, systemic fungicides such as difenoconazole, tebuconazole and other triazoles are combined with protective fungicides such as mancozeb to prevent spot leaf fall disease.

   is pure 10% difenoconazole microemulsion, registered for apple spot leaf fall disease, has protective, therapeutic, and systemic effects. It has been sold for many years and has won the trust of various apple distributors, retailers and farmers. The unique microemulsion type is safer and more efficient. It is an excellent choice for the prevention and treatment of apple spotted leaf disease.
