Are there any insect infestations in the fruit trees in November?

For seedling people, November is also an important period for seedling maintenance.

For example, seedling pests and diseases are one of the most troublesome problems for many seedling farmers, so we can carry out appropriate control measures to ensure the safety of seedlings before they produce pests and diseases.

Winter pruning. The purpose of winter pruning is to allow seedlings to better "preserve their strength", survive the winter dormant period, prune off excess branches and dead branches, and ensure that seedlings can safely overwinter.

The trunk is painted white. Whitening the trunk is not only for the seedlings to overwinter, but also as a measure to control pests and diseases, and also allows the seedlings to germinate slowly, preventing the seedlings from frost in early spring.

Clean up fallen leaves. In late autumn, many pests will choose to hide under the fallen leaves, and our timely cleaning of fallen leaves can also effectively control pests and diseases.

Pest and disease control.

Most of the green plants have scale insects and soot disease associated with the damage.

The occurrence of scale insects is more common, there are many species, and the damage is quite extensive, and in some tree species, even the insect body is covered with stems, branches and leaves, which seriously affects the growth of green plants and the appearance of trees.

The occurrence of soot disease is very common, mainly for the damage to the leaves, shoots, flowers, the disease site to form a soot-like mold layer, in serious cases, the whole leaf is covered into a thin sheet, inhibiting the photosynthesis of plants, weakening the growth potential of plants, and seriously affecting the ornamental effect of garden plants.

Control measures: The whole plant is sprayed with "cocoon biqing" mixed with "spray sterile", which can effectively prevent and control the occurrence of pests and diseases.

Seedlings are cold-proof. Newly planted seedlings need to be protected from cold due to their few root systems and weak tree strength;

Individual varieties need to be protected from cold (such as pomegranate, grape, annual large-leaved boxwood, golden-leaved privet, ginkgo, magnolia, crape myrtle, horse chestnut, chongyang, persimmon, etc.);

Cold-proof methods: ribbons and hedges to build cold-proof sheds, vines buried or covered (such as grapes), frost-resistant arbors and grass ropes to dry, windswept windshields on the windward side, and non-frost-resistant whole plants (such as pomegranates, crape myrtles).

Winter ploughing and deep ploughing. Winter ploughing can cause mechanical damage to underground pests lurking in the soil, and after being exposed to the surface, they can be pecked by natural enemies such as birds, and if necessary, they can also be manually killed.

In addition, deep ploughing buries the pathogens on the surface of the soil into the deep soil layer, and the pathogens in the deep soil layer are turned to the ground, which destroys the suitable environment for pests and diseases, and effectively controls the occurrence of pests and diseases.

I am planting apples, in the management process of apple trees, the prevention and control of insect pests is an important link, the subject said not to be eroded by pests, this I think it is unrealistic to fully realize, only in the process of management according to the law of pest occurrence early prevention, reduce the number of insect population in the orchard, reduce the harm caused by pests to the orchard.

Pest control measures in orchards.

On the apple trees I planted, there will be a lot of pests, common aphids, mites, heartworms, moth pests, elephant pests, scale pests, etc., according to the law of pests, we usually take physical control, chemical control, release of natural enemies and other measures to prevent and control.

First, physical prevention and control.

There are many methods of physical control of pests, the advantage is that there will be no residue, and the disadvantage is that the control effect is often not as fast and thorough as chemical control

Artificial extermination of overwintering pests. For example, scraping the bark in the spring to eliminate the overwintering pests and eggs, and tying grass in the autumn to attract pests into the winter.

Traps trap to kill insects. For example, trapping pests with black lights, decoyants, etc.

Fruit bagging. Fruit bagging is now used a lot, for example, the apple bagging I grow can effectively prevent the damage of heart-eating insects.

2. Chemical control.

Mainly through pesticide control of pests, this is now the main method of pest control, the control effect is fast, but now due to the continuous reuse of insecticides, many pests have produced a certain resistance, and improper use of drugs is easy to cause harm to fruit trees, so more attention needs to be paid to the selection of pesticides and application methods.

Now the application of pesticides is the most spraying, the best time is when the pests overwinter sting or hatching, and then according to the orchard pests and the life of the pests, for example, at this time, apple trees should focus on the prevention and control of mite pests and moth pests.

3. Release natural enemies for prevention and control.

Now in our application here is relatively rare, over the years a large number of pesticides have been used. The elimination of a large number of natural enemies of pests is also one of the reasons why pests are becoming more and more difficult to treat. But releasing the natural enemies of pests is a good way, even if you can't deliberately release the natural enemies of pests, it is also important to pay attention to protection when spraying.

For example, there are a lot of aphids on our apples, so we should pay more attention to protecting ladybugs, lacewings, aphid-eating flies and other insects that feed on aphids, which can have a good effect on the control of pests.

All in all, if you want to keep fruit trees from pests, you must start from many aspects, whether it is physical control, chemical control, suitable natural enemy control, there are certain advantages and disadvantages, and the combination is the best.

Fruit trees in November, after the fruit coloring, is not far from the harvest season, but the prevention of pests and diseases is still not careless, fruit flies, brown rot is the key prevention of pests and diseases in winter.

Anthrax, brown rot, sarptia, and fungal diseases can be treated with fungicides such as azoxystrobin, difenoconazole, and benzoxystrobin. Lice mite urea is used to deal with rusty ticks. High-efficiency thiamethoxam, high-efficiency imidacloprid and high-efficiency acetamiprid can deal with fruit eaters, scale insects and psyllids.

Winter is also the season of red spider outbreaks, and acaricides such as azole difen, ethoxazole, and spirodifen can be used to prevent and control them. Adding safe vegetable oil can better improve the efficacy of the medicine.

Growers work in the fields all year round, and time flies by in a hurry, and soon the end of the year is approaching. The climate is unpredictable, the market is volatile, and we have endless work to face in every season. Only with long-term observation of the environment, in-depth understanding of the characteristics of fruit trees, and hard work can we live a fulfilling and confident life.

Well, hello, there is no deposit for fruits and vegetables in November, there are no pests in the fruit trees in November, the weather is relatively cold, and the insects cannot grow.

Spray pesticides! What else should I do?
