Prevention and control of pests and diseases in the middle and late stages of cucumber breeding

I. Prevention and treatment of diseases Cucumber breeding is mainly caused by downy mildew, keratosis, powdery mildew and so on.

1. Downy mildew: 1 day before watering, spray prevention with 75% chlorothalonil WP 600 times solution. When the central diseased plant is found, the diseased leaves are incinerated in time, and then sprayed with 72% gram of dew 800-1000 times or 72.2% of Plex water 600-800 times.

2. Keratosis: 60% sodium sulphate aluminum WP 500 times solution (also prevent downy mildew) or 72% agricultural streptomycin soluble powder 400 times solution, 27% copper high suspending agent 500-800 Spray control such as double liquid, and prevent 3 to 4 times.

3. Powdery mildew: When the current diseased plant is treated with 27% high-fat film 80-100 times liquid or 2% agricultural anti-120 water agent 100-120 times liquid, 20% triazole copper emulsifiable oil 1500-2000 times liquid, etc. . The above-mentioned agents are used alternately, and are sprayed 2 to 3 times.

Second, the pest control due to the protection of the gauze, the pests in the cucumber breeding field are mainly small insect pests, such as aphids, whitefly, mites and leaf miners.

1. Aphids: In the early stage of the discovery of aphids, spray treatment with 3000 可 可 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 3000 The above-mentioned agents are used alternately, and are sprayed 2 times at intervals of 7 to 10 days.

2. Whitefly: use 蚜虱 可 wettable powder 3000 ~ 5000 times liquid or 69% chlorpyrifos 800 ~ 1000 times liquid, 2.5% Uranus emulsifiable oil 3000 times liquid spray control, the above agents are used alternately, interval 3 ~ 4 Spray 3 times a day.

3. Anthraquinone: It is sprayed with 73% gram of emulsifiable concentrate 2000 times solution or 5% Nisolron emulsifiable concentrate 2000 times solution or 2.5% Uranus emulsifiable concentrate 3000 times solution and 20% chlorpyrifos emulsifiable concentrate 2000-3000 times.

4. Liriomyza: use 5% inhibition of Taibao EC 2000 times solution or 5% card dead emulsifiable concentrate 2000 times solution, 40% green vegetable treasure 1000 times solution and other spray control.
