First, pay attention to the choice of the best pesticide control 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 forest 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, pay attention to the rotation using acaricide
1. When the cockroaches, cockroaches, and pups coexist, the acaricides that are effective in the cockroaches should be used. You can choose 20% 哒螨çµ(苯åŒå¾—,螨代得) WP, 41% diesel? 哒螨çµ(金霸螨,霸螨特) emulsifiable concentrate, 34% diesel? 哒螨çµ(æ€èž¨çŽ‹, 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? four 螨 wettable powder, 10% triazole tin? tetraterpene (Red Lion) suspension, 5% Nisolron EC. 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 Aiwei, for its small size, strong concealment, fast crawling and stronger reproductive ability. Phytoene (Bai-Ten, Red-and-White) emulsifiable concentrate, 1% Avi? High-chlorine (white peony egg) emulsifiable concentrate, 24.5% Avi? Purple (Vicette) emulsifiable concentrate, 35% simvastatin (白螨霸) emulsifiable concentrate.
