Bagged Fruit Spot Disease and Spring Shoot Leaf Spot Disease: Control scab and other diseases in the spring shoot and during the fruit bagging phase. Spray bagged apples with the third treatment being particularly important; continue spraying 3-5 times after bagging, every 10-15 days, to effectively control brown spot, scab, and leaf spot in the autumn shoot phase. For non-bagged apples, start the fourth treatment after petal fall to also control ring rot, anthracnose, brown rot, and glomerella; increase spraying frequency by about two more times to enhance disease control. Use fully chelated mancozeb within 45 days after petal fall to avoid phytotoxicity and fruit russeting. Spray dilution rates as previously mentioned.
Pear Tree Diseases: Primarily control scab, while also preventing sooty blotch, brown spot, ring rot, anthracnose, and powdery mildew. Begin spraying 7-10 days after petal fall, every 10-15 days until 10 days before harvest. For early- and mid-maturing varieties, spray 1-2 times after fruit harvest to preserve leaves. Adjust spray intervals and frequencies based on rainfall; more rain means more frequent spraying, less rain means less frequent spraying. Use fully chelated mancozeb within 45 days after petal fall to avoid phytotoxicity and fruit russeting. Spray dilution rates as previously mentioned.
Grape Diseases: Spray once before flowering and once after flowering to control black rot and downy mildew in young clusters. Continue spraying every 10 days from 10 days after petal fall or when the first downy mildew spots appear on leaves, until about a month before harvest or the end of the rainy season, adjusting spray frequency based on rainfall. More rain means more frequent spraying, and less rain means less frequent spraying. In wet years, spray 1-3 times after harvest to prevent late-season downy mildew. Do not spray non-bagged grapes within 45 days before harvest to avoid contaminating the fruit. Spray dilution rates as previously mentioned.
Peach, Apricot, and Plum Tree Diseases: For scab control, start spraying 15-20 days after petal fall, every 10-15 days until one month before harvest, to also control anthracnose and fungal perforation disease. For brown rot control in non-bagged fruits, start spraying 45 days before harvest, every 10-15 days until one week before harvest, to also control anthracnose and fungal perforation disease. Use fully chelated products on stone fruit trees to avoid phytotoxicity. Spray dilution rates as previously mentioned.
Cherry Diseases: Start spraying at the early stage of disease occurrence, every 10-15 days, for 2-3 times to effectively control leaf spot, fungal perforation disease, and early leaf drop disease. Spray dilution rates as previously mentioned.
Jujube Tree Diseases: Spray once before flowering and once after flowering to effectively control early brown spot and prevent fruit spot disease. Then, start continuous spraying 15 days after petal fall (first crop), every 10-15 days, for 4-7 times to effectively control rust disease, ring rot, anthracnose, brown spot, and fruit spot disease. Use fully chelated products during the young fruit stage to avoid fruit russeting. Spray dilution rates as previously mentioned.
Persimmon Tree Diseases: Start spraying about 15 days after petal fall, every 15 days, for 2-3 times to effectively control common persimmon garden diseases such as circular spot, angular spot, and anthracnose. In southern sweet persimmon production areas where anthracnose is severe, spray continuously for 4-6 times after petal fall, adding 1-2 pre-flowering sprays. Spray dilution rates as previously mentioned.
Chestnut Anthracnose and Leaf Spot: Start spraying at the early stage of disease occurrence, every 10-15 days, for 2 times. Spray dilution rates as previously mentioned.
Walnut Anthracnose and Leaf Spot: Start spraying about one month after petal fall or when the first anthracnose spots appear on fruits, every 10-15 days, for 2-4 times. Spray dilution rates as previously mentioned.
Pomegranate Diseases: Spray once before flowering to effectively control brown spot and prevent anthracnose. Start continuous spraying after most female flowers have set, every 10-15 days, for 3-5 times to effectively control anthracnose, dry rot, brown spot, and scab. Spray dilution rates as previously mentioned.
Strawberry Diseases: Start spraying at the early stage of disease occurrence or when the first spots appear, every 10 days, for 2-4 times to effectively control gray mold and leaf spot disease. For anthracnose control in seedling fields, spray continuously for 3-5 times. Spray dilution rates as previously mentioned.
Hawthorn Diseases: Start spraying about 20 days after petal fall, every 10-15 days, for 2-4 times to effectively control anthracnose, ring rot, and leaf spot. Spray dilution rates as previously mentioned.
Kiwi Anthracnose and Leaf Spot: Start spraying about one month after petal fall, every 10-15 days, for 2-4 times. Spray dilution rates as previously mentioned.
