2, the use of pesticides must be based on the premise of not harming health, using efficient, low toxicity, odorless and tasteless pesticides.

3. When spraying pesticides, you must wear masks, safety gloves and long-sleeved clothes. Smoking and eating are forbidden. People should stand above the incoming wind to prevent the sprayed pesticides from being blown back to the human body and causing poisoning.

Wash your hands repeatedly in running water with soap after spraying pesticides.

Part II Prevention and Control of Common Diseases and Pests

First, common diseases and their prevention and treatment

1, powdery mildew: 800- 1000 times of 50% triamcinolone acetonide, or 0. 1-0.3 baumeishi sulfur mixture, or 50- 100 times of 50% colloidal sulfur solution can be used two or three times a week.

2. Black spot disease: 500-800 times of 75% chlorothalonil wettable powder, 800- 1000 times of Tobuzin wettable powder and 600-800 times of 50% triadimefon are selected as the agents, and sprayed once every 7- 10 days, and the continuous effect is good.

3. Blindfold disease: 70% thiophanate wettable powder or 400-600% carbendazim wettable powder can be sprayed two to three times a week after the onset.

4. Rust: It can be alleviated by spraying a mixture of zinc and sulfur regularly.

5. Anthracnose: The control effect is better with 800 times solution of 75% Baijun wettable powder or 500-800 times solution of Lingjundan.

6. Rhizoctonia solani: Spray 50% carbendazim with 800 times solution for 2-3 times (10 day 1 time).

7. Bacterial wilt: 0.2% potassium permanganate solution or 100-200U agricultural streptomycin and oxytetracycline can be sprayed during the onset period, and potassium fertilizer can be added appropriately.

Second, common pests and their control

1. Aphids: eliminate the overwintering insect source and spray 40% dimethoate 300 times in late autumn for protection. When aphids occur, spray once every 7- 10 day for 2-3 times continuously. It can be killed with 40% omethoate or 40% omethoate 2000 times solution or 8% dichlorvos 1000 times solution.

2. Scale insects: spraying 40% omethoate and 25% 1000-2000 times phoxim. If it is a rare potted variety, it can also be buried in the roots. For 2-3-year-old trees in the hospital, about 40g of 10% carbofuran can be used for each tree.

3. Mites: 800 times of 20% imidacloprid wettable powder, or 2000 times of 50% long-acting sulfur emulsifiable concentrate, and 50% diclofenac emulsifiable concentrate 1000 times.

4. Suma: 300-500 times of 40% dimethoate emulsion, 3000 times of 80% diclofenac emulsion, 4000 times of 50% malathion emulsion and 2000 times of 50% dormant moth pine emulsion have better control effects. 5. Thrips: 300-500 times of 40% dimethoate emulsion, 300 times of 80% diclofenac emulsion, 400 times of 50% malathion emulsion and 2000 times of 50% chlorpyrifos emulsion have good control effects.

Key points of execution operation

1, water in time, according to the growth habits of different varieties and lots (water every 2-3 days indoors or on the wall where the rain can't reach).

2, always pay attention to observe and check whether there are pests, and do a good job in cleaning up litter and drug control, and report the prevention and control situation to the greening department.
