Comprehensive Prevention and Cure of Peach Diseases and Pests

1. How to Prevent Peach Brown Rot?

Brown rot, also known as Sclerotinia, is a common fungal disease that affects peaches. To prevent it, apply 3-5 Be lime sulfur before the peach tree starts to germinate. This helps eliminate overwintering pathogens and also controls leaf thinning and leaf blast. After flowering, spray a mixture of 80% mancozeb diluted at 500 times and "Tianda 2116 fruit tree-specific" diluted at 1000 times, along with Tianda silicone at 3000-6000 times. This combination effectively controls brown rot and other diseases like scab.

2. How to Prevent Peach Leaf Diseases?

During the early growth stage, if the weather turns cold and damp, peach trees are prone to leaf shriveling. When the buds begin to swell and the top buds turn red, spraying 3-5 Be lime sulfur or a 1:1:100 Bordeaux mixture combined with Tianda organic silicon (3000-6000 times) can help control leaf shrivel and also manage anthracnose.

3. How to Prevent Bacterial Canker in Peaches, Plums, Apricots, and Cherries?

Bacterial canker thrives in warm, rainy, or foggy conditions during early spring. To manage this, use 50% thiobacillin (diluted at 500 times or 1000 times for 25%) and 20% kasugamycin (diluted at 500 times), mixed with Tianda organic silicon (3000-6000 times). Alternate sprays every 10-15 days for a total of three applications to control bacterial canker effectively.

4. How to Prevent Gummosis in Peach, Plum, Apricot, and Cherry Trees?

Gummosis is a common issue on various stone fruits. While the exact cause isn’t fully understood, it can be managed by scraping off the gummy areas and applying a mixture of 50% thiobacillus diluted at 50 times and "Tianda 2116 fruit tree-specific" diluted at 50 times. This treatment helps reduce the flow of gum and prevents further damage.

5. How to Control Peach Aphids?

Peach aphids are active from May to June. Two effective methods include: (1) Drying: Mix 40% omethoate with water in a 1:3 ratio and apply it to the trunk using a brush. Create a 6 cm wide ring, then wrap it with paper or plastic film. The effect lasts for at least 15 days. (2) Spraying: After the tree has bloomed, spray 10% imidacloprid at 4000 times or 3% acetamiprid at 1500 times, mixed with Tianda silicone at 3000-6000 times.

6. How to Control Peach Scale Insects?

Scale insects affect not only peaches but also apricots, plums, pears, apples, and persimmons. Before flowering, spray 3-5 Be lime sulfur or 99% green tincture. After flowering, use 48% L. (diluted at 1000 times) or 52.25% farmland (diluted at 1200 times), combined with Tianda silicone at 3000-6000 times to control scale infestations.

7. How to Manage Peach Red Neck Tianniu (Red-necked Caterpillar)?

The peak season for adult red-necked caterpillars is from June to July, especially after rain. During this time, manually remove adults or spray 52.25% farmland at 1500 times with Tianda silicone (3000-6000 times). After harvesting, mix 50% dichlorvos at 40 times with clay and apply it around the base of the tree, wrapping it in plastic film. After 15 days, most larvae will die.

8. How to Control Peach Fruit Pests?

Common pests include aphids, peach borer, and pear borer. Begin control 10 days after flowering by spraying fungicides. Use insecticides such as 52.25% farmland at 2000 times, 30% peach ling at 1500 times, 36% Fudan at 1500 times, or 2.5% lambda-cyhalothrin at 1000 times. Rotate between these products for better efficacy. Mix with 25% Tiandidiurea at 2000 times or 2% Tianda Avid at 4000 times plus Tianda silicone at 3000-6000 times.

9. How to Apply Herbicides in Peach Orchards?

Before weed germination, mix 50% acetochlor (200 ml) with 50% paraquat (100 grams) in 50 kg of water, and add Tianda organic silicon at 3000-6000 times. Spray evenly. During the growing season (July), apply 20% glyphosate (200 ml) per 30 kg of water, mixed with Tianda silicone at 3000-6000 times for effective weed control.
