No. 1500 times or dead fast 1000-1500 times for prevention and treatment. For aphids, 2,500-fold hypertonic imidacloprid and 3000-fold acetamiprid can be used for control. For scale insects, 4.5% beta-cypermethrin is sprayed 1000 times during the larval hatching period; when wax shells are used, 1000-1500 times better killing or new fast-twitch can be used for prevention and control.
5. Strengthen the tree protection work: First, prevent the destruction of humans and animals or the mechanical injury caused by farming; Second, prohibit the burning of wheat stubble near the young trees; Third, do a reasonable pruning, snoring, etc. on the seedlings planted in previous years. jobs.
