Six low-carbon control methods for vegetable pests
1. A "washing urine mixture" prepared by mixing fertilizer with urea, detergent, and water in a ratio of 4:1:400, which is good for many insect pests such as aphids, cabbage caterpillars, and red spiders that harm vegetables and flowers. Control effect; in the spawning period of cabbage caterpillar, with 1% ~ 3% lime water or 1% ~ 3% calcium superphosphate leachate spray, within a week can avoid eggs more than 52%, the effect of the fifth day up to 84%. 2. Measure 100 grams of cabbage worms per acre with insect pests, smash and rot, mix with 250 ml of water, add 50 grams of detergent, and then mix with 50 kg of water to compose 0.2% of cabbage worm body fluid to prevent and control cabbage worms. The effect can reach more than 90%. 3. Germ spores used as a main medium for the cultivation and propagation of corn flour by bacteria to prevent and control greenhouse whitefly, the parasitic rate of the whitefly nymph can reach more than 80%. 4. Heaps of grasses and traps The quail is perched on the underside of a thin layer of grass. The small haystacks with a thickness of 10 to 20 centimeters are placed evenly on the field in rows of 5 meters and 3 meters long. The grass will be collected and killed the next day; Putting poison baits under the haystack or using a wooden stick with a diameter of 3 to 5 centimeters will make it better. This method is not convenient for large-scale promotion and is suitable for application in vegetable fields. 5. Yellow traps kill aphids, whiteflies, etc. have strong tropism toward yellow, yellow traps can be set to kill adults. Method is: the fiberboard or cardboard cut into 1 meter 0.2 meters long, painted orange peel yellow, and then coated with a layer of sticky oil (add a little oil with a small amount of oil on the 10th), 32 to 34 pieces per acre, home Between the rows, the bottom of the yellow plate is at or slightly higher than the top of the plant. When aphids, whitefly, etc. are stuck on the board surface, it is necessary to reapply the sticky oil in time. Generally, it can be re-coated once every 7-10 days. 6. Sex Hormones Trapping At present, there are roughly three forms of sex pheromones: the use of synthetic sex pheromones (called "sex attractants"), the use of crude extracts of sex hormones, direct use of uncoordinated Living females. The trapping and killing of female moths is simple, low-cost, easy to popularize, and the effect is obvious when the amount of insects is small. The practice is: make a circular cage with a length of 10 cm and a diameter of 3 cm with a 50- to 60-mesh insect net, and place 1 to 2 un-matted female moths in each cage (you can collect females in the field first When the feathers are used, wait until they are used. Hang the cage on the basin. The basin is filled with a little kerosene and put into the field after dusk. It can kill many male moths every night.
