1. Trichogramma control: Trichogramma is safe, non-toxic, non-polluting and pollution-free. It is easy to use and has good control effect. Prevention and treatment time: Each bee was born in the first generation of the egg of the field generation (the adult emergence rate reached 15%) and the peak period (usually about 7 days after the first release of the bee). Put the bee method: put 2 bees per acre, put 7000 for the first time, put 8000 for the second time, put 3 points per acre, select robust corn plants on the point, on a leaf surface in the middle, along the main vein Tear it in half, take half of it and put it on a bee card, gently roll it into a tube in the direction of the stalk, and fix it with a thread. However, the use of Trichogramma to control the corn borer needs to pay attention to three issues: First, the bees on the day of the card, the release of the same day; Second, when the card is torn, the falling eggs will be concentrated together; Third, when hanging cards, the leaves do not roll too tight So as not to affect the bees. 2. Control of Beauveria bassiana or Bt powder: The main method is to seal and kill cockroaches. The method is to use 5 to 10 billion pieces of Beauveria Bacteria powder or Bt powder before emergence of the 4 to 5 months of corn cob, spraying 100 grams per cubic meter. In addition, straw stalks can also be used to kill overwinter larvae; corn stalks can also be fermented before emergence of corn stalks. 3, the use of bacteria to cure earthworms: In the corn leaf stage, each plant generally applies 2 grams of Beauveria bassiana granules, or Bt powder per acre 80 to 100 grams, made into granules, applied to the heart of the corn leaves, with bacteria to cure maggots .
