1, in the citrus garden to promote the use of warts. The main contents of the wolfberry clams are: adopting grass cultivation, establishing ecological orchards, restricting the use of pesticides, and establishing predatory clam populations through the release of predatory mites to achieve long-term control of pests. The specific approach is to choose a citrus garden that is over 5 years old, and to develop grass cultivation, such as planting perilla, hibiscus, and october, etc. It is generally released once after the spring peak (after April-May). However, the orchards that have suffered severe damage all year round can be released again before August. This year due to the impact of the earthquake, the unfinished tasks in the spring should be completed in the fall. 10-15 days ahead of time to implement a pesticide control of pests and diseases in the orchard, both to prevent other pests and diseases, but also reduce the number of pests. The number of pests (including eggs) must not exceed 2 heads/leaf when released. In principle, each tree is hung with a bag of slow-release predators (containing 500-600 predators) and hung on the first branch of the base of the canopy. It is usually best to hang in cloudy or early evening, and it is better not to rain in 1-2 days after release. Disable insecticide acaricide after release.
2, vegetable pests "three induced" technology. The first is to popularize the technology of vibration and induction of agricultural pests. When installing frequency-vibration insecticidal lamp, the distance between each lamp is 200m, the control area is about 40-50mu, and the lamp is 1.3-1.5m from the ground. The second is to demonstrate the development of sex traps to trap vegetable pests. The method of using the sexual attractant is to cut a lure for cutting the opening of the packaging bag and insert the lure into the lure handle of the trap. The beet armyworm and Spodoptera litura lures per 1–2 mu were placed at a height of 1 meter from the surface of the crop. The diamondback moth has 3 to 5 lures per acre. The traps are placed at a height of 20 cm from the surface of the crop, and they are better placed in a concentrated piece. Change the lure every 4-6 weeks. The sex pheromone product is volatile, so it needs to be stored in a refrigerator with a lower temperature. The lure should be protected from sun exposure. Open the sealed bag before use. The third is the use of yellow armyworm board traps kill aphids, spotted fly and other pests. 20 yellow plates per acre are placed in a “Z†shape, standing slightly above the top of the vegetables.
3, promote biological pesticides. Natural pyrethrins were used to control vegetable pests such as Brassica juncea and Plutella xylostella and applied 30 ml per acre in the young larvae. Application of streptozocin to prevent rice sheath blight, rice smut, etc., 300 ml per mu. The promotion of microbial pesticides to control pests, such as Metarhizium anisopliae against aphids; Ningnanmycin against vegetable virus disease; Bt emulsion against diamondback moth, cabbage caterpillars, leguminosae and other lepidopteran pests.
4. "Bio-Missile" technology to prevent corn borer. Select large-area plantings, corn production areas where pests occur year round, and the most severe ones. In the first or second generations of corn cocooning, the peak period of spawning, or the beginning of spawning to the end of spawning, the “bio missile†products are hung on corn leaves. On the main vein, or to pick up wood sticks (one for each stick) and insert it in the corn field, apply 4-5 pieces of equidistant distance (2 meters from the side of the field) per acre. No insecticide can be applied after bombing. The environmental conditions for the preservation of "biological missiles" are demanding, and qualified regions can acquire cold storage facilities for the preservation of "biological missiles."
