The agent used to control herbivorous mites is called an acaricide . Common acaricide varieties are cockroach, ketone, and nisol. The following small series introduces you to the use of acaricide.

First, choose the best treatment period medication. Try to choose to spray at the beginning of the disaster, when the population density and quantity are small, to increase the duration of acaricide and reduce the number of uses. The best control period on the fruit trees is half a month after the flowering of the flowers, that is, the first generation of the eggs of the first generation hatching and before the wheat harvest.

Second, the use of acaricides. 1. When the cockroaches, cockroaches, and pups coexist, the acaricides that are effective in the cockroaches should be used. 20% 哒螨灵(苯双得,螨代得) WP, 41% diesel·哒螨灵(金霸螨,霸螨特) emulsifiable concentrate, 34% diesel·哒螨灵(杀螨王, Sputum sputum) emulsifiable concentrate, 73% of ketamine emulsifiable concentrate and other acaricides have the characteristics of good killing, high efficacy and full function. One of them can be used for rotation to achieve the purpose of controlling mites. 2. When the egg mites with more eggs are coexisting, a long-acting acaricide with good egg-killing effect and ovulation treatment should be used. 10% 哒·四螨 (fruit full red) suspending agent, 12% 哒·螨 螨 wettable powder, 10% triazolyl·tetrazine (red lion) suspension, 5% nisolron emulsifiable concentrate can be used. These agents can penetrate the eggs and prevent the eggs from developing and hatching, so as to control the rapid growth of the density of the mites. 3. When the damage of the two-spotted spider mite (white spider) rises, choose a special agent for killing white spiders, such as 15% Xin·Avi, for its small size, strong concealment, fast crawling and stronger breeding ability. A bacteriocin (Bai-Ten, red and white) emulsifiable concentrate, 1% Avi·Hyperchlor (white peony egg) emulsifiable concentrate, 24.5% Avi·Zi (Virten) emulsifiable concentrate, 35% sim avermectin (白螨霸) emulsifiable concentrate.

Third, pay attention to spraying skills. Spraying should be done evenly and thoughtfully, paying special attention to the densely packed eggs on both sides of the main vein on the back of the blade. For specific operations, spray until the tree is wet to drip.
