Peach Tree Powdery Mildew: Control Methods and Key Technical Points
Control methods for peach tree powdery mildew: 1. After leaf fall, remove diseased leaves to reduce the source of infection. 2. Spray fungicides for protection during the growing season: in the early stage of the disease, spray 0.2 to 0.3 degrees Baume lime sulfur mixture, or a 2000 to 3000 times dilution of 15% wettable powder triadimefon, or a 1500 to 2000 times dilution of thiophanate-methyl. 3. Improve ventilation and light penetration...

Improve ventilation and light penetration conditions: for greenhouse peach trees, improve the light conditions of the tree by adjusting the tree structure, the population structure and the amount of branches and leaves; reduce humidity through ventilation to create environmental conditions unfavorable to pathogen infection.
