In the apple flowering period, the incidence of mycotic disease is the highest. The flowering period is also the peak of the occurrence of powdery mildew, spotted deciduous disease, aphids, and spider mites. The prevention and control methods are as follows: 1. Spray 800 times of new high fat film powder in the inflorescence separation period, and add 25% triadimefon WP in 1500~2000 times in the orchard with heavy powdery mildew. If there are locusts, red spiders, should be mixed with non-polluted pesticides plus 10% tetraflumuron suspension 2000 times, mixed spray. 2. Control chafer, mu 500ml 48% chlorpyrifos EC, plus 800 times the new high-fat film ground spraying, do not move after spraying, can effectively control chafer. 3. Carefully and thoughtfully when spraying, the front and back of the canopy and inner canopy and leaf skin should be evenly sprayed. Many fruit growers are accustomed to spraying with spray guns. Although the spray guns are highly efficient and relatively labor-saving, if they are not well-kept, the fog is often very rough, and it is difficult to form a uniform film on the foliage and flower surfaces. This is a waste of pesticides. It is recommended that the atomization effect be good. Sprayer sprays medicine.
