1. The main diseases harmful to cucumber are seedling damping-off, seedling blight, downy mildew, powdery mildew, bacterial leaf spot, anthrax, epidemic, and root-knot nematode disease.
2. The main insect pests that damage cucumber are aphids, leaf miners, tea astragalus, cinnabar leaf aphid, and melon aphid.
II. Occurrence and key prevention targets
In the early December and early February, the diseases that threaten cucumber seedlings are mainly damping-off and anthracnose; insects include aphids and floorworms.
In the middle of February to early April, the main diseases that damage cucumber are the disease, wilt disease and anthrax. The pests mainly include locusts and spider mites.
In mid-April to early-May, the temperature rose. In addition to diseases such as epidemics and anthrax, downy mildew also occurred. The increase in pests was mainly due to roundworms, aphids, spider mites, leaf miners, and melons.
In mid-May to early-June, there is more rain and temperature rise, the main diseases are mainly downy mildew, powdery mildew, bacterial angular spot, and blight may occur;
In the middle of June to late June, the temperature rises root knot nematode disease is prone to occur.
Third, control strategy
The main focus is on agricultural control, and chemical control methods are used in due course.
Fourth, agricultural control
Implement crop rotation to avoid continuous cropping with melon vegetables, deep ravine sorghum, spraying more potassium dihydrogen phosphate on the leaves, strengthening ventilation, and reducing humidity in the shed. High-temperature stuffy sheds reduce the risk of downy mildew, prevent accumulation of water, and pay attention to clean the garden.

1, downy mildew can be used 72% Ke Lu WP500-800 times, 64% anti-drug WP800 times, 25% metalaxyl WP300-500 times spray control.
2, damping-off, blight with 50% carbendazim WP1000 times Irrigation control.
3, powdery mildew can be used 15% triadimefon WP750-1500 times spray control.
4. Anthrax disease and epidemic disease can be controlled by 80% mancozeb WP500-800 times or 70% phosporium aluminum manganese zinc WP800 spray.
5. Bacterial leaf spot can be controlled by 72% agricultural streptomycin SC4000 liquid spray.
6, root knot nematode disease can be used 40% chlorpyrifos EC500 times spraying the soil surface.
7, aphids can be controlled by 0.6% avermectin EC1000 times spray.
8. The leaf miner can be controlled by 0.6% avermectin EC1000 and 40% chlorpyrifos EC500.

10. Trichosanthes can be controlled with 5% Frigid SC1000 or 40% chlorpyrifos EC500 spray.
6. Harvesting
