Peach trees are prone to aphids, so they should be prevented in time, otherwise it will be difficult to treat when the aphids come up.

Common peach tree aphid control agents are: imidacloprid, anti-aphid, acetamiprid, pymetrozine, flufenamide, halodioxaline, dinotefuridin, thiamethoxam, ethylspinodidone, thiazinone, bifenthrin, thiamcloprid, dinotefurid, etc. Recommended Blending Agents:

Fluacetamiprid, pymetrozine, ethyl spirometrox + dinotefuran, pymetrozine + dinotefuran, cyhalothrin + imidacloprid, ethyl spirometh ester + pyrpropyl ether + dinotefuran, ethyl spiromex + pymetrozine, ethyl spiromethane + thiamethoxam, thiamethyl chlorofluorine, pyridazine, pymetrodi, bifenthrin + imidacloprid, etc.

Characteristics of different agents:

1.In recent years, from the experience of aphid control, the effect of the commonly used drugs acetamiprid, imidacloprid and pymetrozine has become worse and worse, and the resistance of aphids has become stronger and stronger.

2.Halodioxapyr is currently a good agent for the control of peach tree aphids, which has the ability to kill aphids, can also be absorbed, and has high efficiency in killing aphids, has a long lasting time, and is resistant to rain washing, and can be used twice at most in a growing season.

3.Snail ethyl ester has two-way systemic conductivity, moving up and down throughout the plant to reach the leaves and bark, pests on the bark, prevent the larvae of aphids from growing, have a long effective period, and can provide effective control for up to 8 weeks.

4.Pymetrozine has contact killing and systemic effects. As soon as the aphids come into contact with pymetrozine, they almost immediately produce a needle-blocking effect, immediately stop feeding, and eventually starve to death. The 48-hour lethality rate can reach 100%.

5.Thiamethoxam has contact killing, stomach toxicity, systemic properties, fast action speed, long duration of effect, can control aphids, leafhoppers, whiteflies, beetle larvae, nematodes, ground beetles, leaf miners, etc.

6.Dinotefuran has the characteristics of contact killing, stomach toxicity, high fast effect, long duration of 4-8 weeks, wide insecticidal spectrum, etc., has excellent control effect on aphids, and shows high insecticidal activity at a very low dose.

After the leaf development, the reproduction rate of peach aphid began to accelerate, the fastest growth from April to June, should be sprayed once every 7 10 days according to the occurrence of insect pests, and the agent can be selected with 50% pymetronics isoprocarb wettable powder 2000 times liquid.

1. Prevention and control methods of peach tree aphids.

1. Agricultural control: In autumn and winter, cut off the branches and leaves with insect pests, scrape off the skin of the peach tree, and then take the fallen branches and leaves in the orchard and the cut branches and leaves out of the peach orchard to be burned, destroy the living environment of aphids, and reduce the number of eggs in the orchard.

2. Biological control: In the early stage of aphids, ladybugs are released in the orchard, generally 100 calories per mu (20 eggs per card) are placed to kill aphids, and at the same time protect the natural enemies of aphids such as lacewings, aphid flies, aphid cocoon wasps, parasitic wasps, and ladybugs.

3. Physical control: using the aphid's yellow tropism, use a rectangular cardboard, coat a layer of yellow advertising color on the cardboard, then apply a layer of viscous oil on the cardboard, and finally put these cardboards in the orchard to eliminate aphids. Or apply a layer of white substance to the stem of the peach tree to use the aphids' anti-silver properties to repel aphids.
