What should I do if there are clams on fruit trees?

We've been fighting drought these days, and while watering I'm watching the water flow while killing clams, this year's apple trees.

There are a lot of clams on it, and if they are not eliminated in time, they can cause serious damage.

Let's get to know this clam first, I mainly grow apple trees, I will talk about the clams on our apple trees, the picture below is their excretion hole, as long as there are such excretory holes on the tree, and you can see that there will be excrement outside, then that's right, there must be clams inside.

These guys spent their childhood in tree trunks, white and fat, don't look at it as foolish, it harms fruit trees, it is not ambiguous at all, it eats the xylem of tree trunks.

Hiding inside, they don't care at all with ordinary sprays, and it can be said that they won't hurt them at all.

When they grow up, they are not at all what they were when they were children, they will grow wings and become a longhorn beetle. The most serious damage they do to fruit trees is when they are young, which is also the most important time to get rid of them, but they hide in the trunk of the tree, and the spray does not work, what should we do? We growers still have a way.

The first way is to use a syringe.

Spraying medicine into its excretory holes, the agent must be an insecticide, phosphine.

The effect is good, the concentration is higher, and it is basically no problem to inject ten milliliters into one hole.

The second method is to find a small branch that is about the same thickness as their hole, dip it directly in the original medicine, and plug the hole for it, so that the clams will come and bite the branch that is blocking the hole, and there is medicine on the branch, so that they can be directly destroyed.

At present, there is no better way to deal with clams, although these two methods are slower, but for the elimination of clams, the effect is still good.

Therefore, the old farmer of Seven Stars personally thinks that there are clams on your fruit trees, and it is recommended that you use fresh quicklime.

You can choose some insecticides to spray him. You can also use motor oil and some insecticides to make a certain proportion, and the application can also effectively kill these pests.

If there are clams on the fruit tree, special pesticides are required, but the type of pesticide and the amount of spraying should be selected according to the variety of the fruit tree to prevent the fruit tree and the surrounding environment from being polluted by pesticides.

A: The simplest and most direct method is to grasp it manually. In addition, you can brush the trunk with lime water, which can effectively prevent insect pests. In addition, after the fruit is harvested, observe the nests of insects, cut them down, and take them to another place to destroy.

First, the simplest way to control the worm, manual capture Second, timely clearing of the garden, reduce the hiding place of pests Third, the trunk is coated with quicklime has a good insecticidal effect.

1. The trunk of the tree is whitened with lime liquid; Prevent the red-necked beetle from laying eggs on the trunk of the tree.

2. Sugar, wine and vinegar booby-trapping; The ratio is 1 part sugar, one part wine, one part vinegar and 8 parts water, and hang it on a tree to trap adults.

In the process of daily management, the straw is burned into plant ash, soaked in water for a dozen or two days, properly added water and fully stirred, and then sprayed on fruit trees and trees every other day.
