Prevention methods (1) During March-April, when the overwintering eggs of peach trees were hatched, when the winged beaks had not occurred yet, the spraying of pesticides was controlled in time to reduce the amount of tobacco fields. (2) Promoting silver-gray film-covering seedling cultivation technology Daejeon advocates the use of silver-gray film-planted tobacco to promote flood control and reduce the effects of smoke-and-pox transmission. (3) In the period when peach aphid migrates to the tobacco field, it is timely to spray 0.9% aforein EC 2000 times or 50% ACV WP 2000-2500 times, 40% LEGO EC 1000 times, 2. 5% deltamethrin EC, 20% fenvalerate EC, 10% cypermethrin EC 2500-3000 times solution, sprayed 75L per 667m2 solution. The areas that are resistant to the above insecticides can use 20% Confodol (Imidacloprid) concentrated solvent, 6-8 ml per 667m2 or 35% Sai Dan EC 75-100ml.
KN95 Masks are anti-virus. KN95 masks are similar to N95 masks, except that one is a Chinese standard and the other is an American standard.
If there are two numbers of 95, it means that the protective ability of this mask is above 95%. That is to say, for tiny substances larger than 0.3 micrometers, the mask has a defensive ability of more than 95%, and it can block tiny substances larger than 0.3 micrometers outside the mask. Viruses and bacteria are generally larger than 0.7 micrometers. Therefore, using a mask such as KN95 can effectively protect against viruses.
