In order to ensure the production of high-quality, small melons, pest and disease prediction should be strengthened, and prevention should be the priority. When pesticides are used, they must be strictly implemented according to NY/T393. The use of prohibited pesticides is strictly prohibited. The combination of artificial, biological control and physical and mechanical control should be adopted to eliminate pests and diseases in the bud stage.
Disease prevention and control of major diseases are virus disease, gray mold, powdery mildew.
Zucchini powdery mildew
Chemical control: In the early stage of onset, thiophanate-500 times, or 50% sulfur suspension 250 times; biological control: spray with 2% antimycotic (agricultural 120) water 200 times; physical control: 27 % High Fat Film Emulsion (80-100) Liquid Spray.
Viral disease
Strengthen management and apply basic fertilizer; cultivate strong seedlings, find a few diseased plants at the seedling stage, remove and remove new sheds, and remove new saplings; identify diseased plants at fruit stage, and individually control pesticides; control locusts and greenhouse whitefly in time; Control of such pests; chemical control: Spray once a day every 10 days, 2.5% of plant diseases, WP, 1000 times, or virus A, 600-700 times, alternating between the two drugs.

powdery mildew
Biological control: Use agricultural anti-BO-10, concentration 100 units, early onset of spraying, once every 7 days, 2-3 times in succession; Chemical prevention and control: Chlorothalillic aerosol smoke control, before closing shed, 200 - 250 g evenly placed in the greenhouse, closed after the ignited greenhouse, the next morning ventilation smoked net; or 25% Triadimefon 2000 times, 15% Triadimefon 1000 times spray, once every 7 days, continuous spray 2- 3 times. The above pesticides were stopped 7 days before harvesting.
Pest control The main insect pests are grasshoppers, greenhouse whitefly, and leafminer.
High-quality melons, various pests, prevention and control method for cucumber pest control. There are mainly maggots and Liriomyza. Aphid control can use 0.5% of warfarin alcohol solution 800 times or the control of virulent mold. The above pesticides were discontinued 15 days before harvest
Harvest small melon grows fast, high yield, timely harvesting; when the length to (200-400) grams, can be harvested; cut with a knife from the handle, with a melon net set; collected If it is too small, the yield will not go up; when the harvest is too large, it will affect the growth of the upper melon and reduce the quality.
During transportation, no toxic or harmful substances shall be contacted or transported in transit; the means of transportation shall be cleaned and kept clean before and after transportation.
Storage and storage products must be inspected by product quality inspectors before they can be stored in the warehouse; storage sites should be clean and hygienic, not mixed with toxic and hazardous materials mixed storage; storage temperature should be 3 °C -5 °C.
