How to prevent peach aphids

Aphid damage

The main types of peach aphids are peach white aphid and peach gall aphid. They occur all year round, mostly appearing in May and multiplying in large numbers. In June and July, they will move to other flowers to reproduce and cause harm, and then return to peach flowers in September and October to lay eggs over the winter.

Prevention and treatment methods

Cut off the insect-infested branches with eggs; spray pesticides for prevention and control during the budding period and peak growth period. Use 1500 times more omethoate and other pesticides for prevention and control; at the same time, protecting and utilizing its natural enemies to fight it is also a wonderful strategy.

How to prevent and control peach red spider

Red spider mites

The damage caused by red spider mites to peach blossoms is extremely serious. When the leaves are infected, many yellow-white or gray-white and dark green spots will appear on the petiole, and a silk screen will appear. In severe cases, the disease will expand into a large area, becoming large dead spots, causing the leaves to gradually wither, turn dark yellow and fall off.

Prevention and treatment methods

Before budding, the rough and peeled bark on the main branches can be destroyed collectively to eliminate a large number of overwintering red spider mites. The earlier the chemical control is applied, the better, especially for the first generation of pests, which have no antibodies, poor resistance and are extremely easy to eliminate. You can also use 20% trichlorodicofol 6OO and other liquid medicines for prevention and control.

How to prevent and control peach leafhoppers

Green leafhopper damage

Green leafhoppers seriously damage the sap of new shoots and leaves. There are five generations each year, and they overwinter as adults. In autumn and winter, pay attention to removing insect-infested branches and leaves, and destroy them collectively to prevent pests from occurring again.

You can also use 1000 times of omethoate and other pesticides for prevention and control. The female adults continuously lay eggs in holes on branches and leaves, causing the leaves to wither and die.

The eggs hatch in June of the following summer, sucking the sap from the young roots, and burying themselves in the soil in late autumn to hibernate.

Prevention and treatment methods

Eliminate infested branches in autumn; you can also catch and kill them in the early morning during their emergence period, or lure them by making a fire at night; tie plastic film on the tree trunks to intercept and protect them, about 3-4cm wide; use 1000 times the concentration of omethoate for spraying during the emergence period of adults.

How to prevent and control the pink-necked longhorn beetle

The harm caused by pink necked longhorn beetle

The larvae of the peach-necked longhorn beetle eat away at the branches and stems, gradually hollowing out the inner stems of the main branches, causing the peach flowers to shed leaves, wither, and gradually die.

One generation of damage takes 2-3 years, and most of the insects are larvae.

Prevention and treatment methods

1. Catch the adults on branches and trunks during the adult stage;

2. Before the adults emerge, whitewash the trunks and main branches to prevent them from laying eggs;

3. During the larval stage, use lead wire to hook and kill the larvae through the excrement hole along the tunnel;

4. Use dichlorvos, omethoate, etc. to poison pests.
