2. Pre-sprouting prevention and control methods: dry branches spray 14.5% of duoxiaoling (ammonium copper complex) 150x solution, or 43% tebuconazole 2000 times solution, etc., then add 2000 times of chlorpyrifos solution, 100x solution of urea, and 20-25 times solution of zinc sulfate in orchards with severe lobular disease.

The time of prevention and control in young fruit stage: around May 10, spray once 7-10 days after Xiehua, then spray once every 7-10 days, spray 3 times continuously, pay attention to the combined use of protective fungicides and internal absorption fungicides, and add appropriate amount of foliar calcium fertilizer.

2. Control objects 7-10 days after flowering: 7-10 days after flowering (80% of flowers fall off), mainly control ring disease, anthracnose, pink scale, spot leaf disease, red and white spiders, leaf moths, leaf rollers, aphids and so on.

3. 7-10 days after flowering, prevention and control methods:

(1) use 80% mancozeb 800-fold solution, or 70% propionate zinc 700-fold solution, plus 50% carbendazim 600-fold solution, or 70% methyl thiophanate 800-fold solution fungicide for control.

4. About 20 days after flowering, the object of control: about 20 days after flowering (around May 20), mainly control anthracnose, ring streak, spot leaf disease, Kangs pink scale, yellow mole, aphid, cotton bollworm, leaf rollers and so on.

5. Prevention and control methods about 20 days after flowering:

(1) 1500-fold solution of 10% polyantimycin or 43% tebuconazole 5000-fold solution plus 50% carbendazim or 70% thiophanate-methyl can be used for control.

(2) 10% imidacloprid 3000 times, 52% chlorpyrifos 1500 times, or 10% cyhalothrin 2000 times insecticides can also be used for control.

April and June (fruit expansion period)

1. Pest control in the middle of June: Bordeaux solution was sprayed once in the middle of June after bagging.

2. The objects of prevention and control 3 days before bagging: ring streak, anthracnose, aphids, leaf spot, pink scale, peach heart borer and so on.

3. Prevention and control methods 3 days before bagging:

(1) use 80% mancozeb 800-fold solution, or 70% promethazine 600-fold solution, plus 70% thiophanate-methyl 800-fold fungicide for control.

(2) 10% imidacloprid 3000 times, 1.8% avermectin 4000 times and 40% chlorpyrifos 1500 times insecticides can also be used for control.

4. the object of prevention and control after bagging: Brown spot, ring disease, peach heart borer, etc.

5. Prevention and control method after bagging: use 1-D-3-mer 200-fold Bordeaux liquid fungicide for prevention and control. It can also be controlled with 20% cyanogen horse EC 1500 times liquid insecticide.

May, early July to the end of August (fruit expansion period)

1. Control objects from early July to the end of August: from early July to the end of August, mainly control leaf spot, brown spot, leaf miner, red and white spiders, etc.

2. Prevention and control methods from early July to the end of August:
