There are many factors that induce black spot disease in peach trees, among which excessive application of nitrogen fertilizer will cause the fruit to be infected by the fungus when the plant grows vigorously. If there is too much nitrogen, the fruit tree lacks calcium and potassium nutrients, and it will be easy to be infected, and the nutrient deficiency tree leaves are large and thin, the photosynthesis is weak, the fruit coloring is poor, the quality is poor, the sugar content is low, and it is not resistant to storage. Long-term application of chemical fertilizers is easy to cause soil compaction, etc., and the plant growth is weak and easy to be infected. Moreover, the peach tree orchard is impermeable to wind and light, which can aggravate the occurrence of the disease.

Diliwang microbial agent can improve the soil, solve the problems of soil clay weight, compaction, acidification, poor air permeability, etc., which can improve the soil fertilizer storage and water retention capacity, can inhibit the infection of harmful pathogens, enhance stress resistance, promote root growth, and enhance tree potential.
