Repellent technology is a targeted preventive measure designed by using pest activity habits or pathogen transmission routes, mainly including the setting of insect nets, the application of non-woven fabrics, covering silver-gray mulch film and planting avoidance plants with lights.
First, set up anti-insect nets
It is mainly used for vegetables or fruit trees in facility protected areas. After being covered with applications in the facilities, it can not only control the pests of more than 20 major pests such as cotton bollworm, beet nocturnal moth, twill nocturnal moth, silver-striped nocturnal moth, kale nocturnal moth, small cabbage moth, tobacco green worm, green cabbage worm, green cabbage worm, ape leaf worm, jumping beetle, tobacco whitefly, aphid, spotted fly, melon silk borer, etc., but also block the occurrence of dozens of viral diseases transmitted by vectors such as aphids, whitefly, thrips, spotted flies, etc., so as to achieve the dual effect of preventing insects from directly harming and controlling viruses.
Second, the application of non-woven fabrics
Non-woven fabrics such as crop protection cloth, seedling cloth, irrigation cloth and insulated curtains used in protected area cultivation can also play a role in disease prevention and pest control. Due to the large temperature difference between day and night, high humidity and easy condensation in the protected area of the facility, it often causes the bacteria to spread the disease with the dew drops. In early spring and late autumn, during the period when the shed is easy to condense, the use of non-woven fabrics for covering can play a role in reducing humidity and reducing condensation, thereby preventing the occurrence of gray mold, sclerotia, blight and so on or reducing the incidence of disease. At the same time, it also plays a role in insect prevention, heat preservation and frost control.
3. Cover with silver-gray mulch film
It is mainly used to avoid silver gray by small pests such as aphids and whiteflies, and is used to avoid pests and prevent viral diseases.
Fourth, plant repellent plant belts
It is mainly a planting mode designed by taking advantage of the strong tendency of certain pests to specific plants or the characteristics of rejection of specific plants. Some can play a role in pest prevention, and some can play a role in protecting and utilizing predators. This also falls under the category of ecological regulation technology.
