How to deal with peach blossom pests and diseases, symptoms of peach blossom pests

1. Brown rot

Brown rot is a common disease of peach blossoms. In the early stages of the disease, small black spots will appear on young fruits, followed by cracks on the surface, which can also cause the fruit to rot. It is usually necessary to cut off diseased branches, remove diseased fruits and burn them in a centralized manner in winter. Spray Mido lime sulfur during the bud swelling stage, and spray Zineb or Thiophanate-methyl from after flowering to before harvest, once every 10-15 days.

2. Anthrax

Anthracnose usually occurs during the fruiting period. Diseased fruits will develop brown-green spots, which will then expand and become sunken, and pink spore clusters will appear. In severe cases, the fruit will rot and fall off. If you want to prevent and control it, you need to avoid planting in low-lying areas and pay attention to fertilizing to increase the plant's disease resistance. In addition, you can also spray sodium pentachlorophenol or Bordeaux mixture for prevention.

3. Aphids

Aphids mainly harm plants in March and April. These pests gather on the underside of leaves and suck their sap, causing them to fall. In winter, it is necessary to promptly remove fallen leaves, cut off damaged branches and use imidacloprid for prevention and control. In addition, biological control can also be carried out by protecting its natural enemies, such as ladybugs.

4. Red spider

Red spider mites usually appear in April, harming the tender shoots of plants. The situation is most serious in June, easily causing massive leaf fall. To control this pest, you need to spray lime sulfur before germination to kill the overwintering female insects. After the flowers fade, spray persistent miticides such as Nisolan emulsifiable concentrate. If the situation is serious, use drugs such as cypermethrin for treatment.
