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. 20% lingering wettable powder, 41% diesel oil, lingzhi emulsifiable concentrate, 34% diesel oil, lingzhi emulsifiable concentrate, 73% ketone emulsifiable concentrate and other acaricides, all have quick killing effect and efficacy High and full-featured features, one of which can be selected for rotation to achieve the purpose of controlling pests.
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 螨 螨 suspending agent, 12% 哒. 螨 螨 wettable powder, 10% triazole tin. tetraterpene suspension, 5% nisolron emulsifiable concentrate. 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 mites (white spider) rises, choose a special agent for killing white spiders, such as 15% simvavirus, for its small size, strong concealment, fast crawling and stronger breeding ability. Plain emulsifiable concentrate, 1% avico emulsifiable concentrate, 35% avermectin emulsifiable concentrate.
