Pests harm plants, causing great losses to agricultural production. Therefore, humans use various pesticides to prevent and control disease at all costs. However, many pests still occur and even become harder due to drug resistance. After careful research and repeated trials, some people finally found a low-cost, cost-effective, simple, and easy-to-use method for using dead insects to control living insects. At present, this technique of using dead insects to control live insects has gained people's attention and application. Interested parties may wish to try: The method is: After capturing some pests, dilute with water and dilute them, and then spray them on crops that are harmed by the same pests, and live insects will die. For example, if 100 g of armyworm is caught, minced and diluted with appropriate amount of water and filtered, then 60-80 kg of water is added to the filtrate, and then sprayed on the rice where the armyworm occurs. The armyworm will die in large numbers and even disappear. Capture or collect dead insects such as cabbage caterpillars 100 grams from the field, grind them to rot, add 200 ml of water, soak for 24 hours, filter out the larvae, add 40 kg of water, and add 50 g of detergent to mix. Then This dilution is sprayed on crops such as vegetables where the same kind of pests occur. According to reports, the use of this method to control cabbage caterpillar, land tiger, armyworm, tapeworm and other pests, the effect is very satisfactory, pest mortality rate of up to 90%. Why can dead pests kill and live pests? It turns out that pests carry pathogens, viruses, and other pathogens. After spraying the diluted solution of dead pests on living pests, the pathogens will spread, causing the living pests to become infected. At the same time, after spraying the solution of dead pests, the smell of this pest in the field is more concentrated, which attracts a large number of natural enemies to kill. In addition, dead pests also produce a volatile substance called a terrorist hormone that can be terrorized by similar insect pests. The result is not to be starved to death by intimidation, or to death by infection.
