Apple orchards, not only in the summer but also in the fall, need our protection and more attention. We will discuss how to properly treat apple trees for pests and diseases in the fall, and what preparations should be used to treat trees before overwintering. You will learn more about Autumn Pest Control Treatment for Apple Trees by Bubgo article.
In the fall, apple trees are treated for pests by spraying, but you should not rush to use them. Only process them after the trees have shed more than 60% of their leaves and the entire crop has been harvested from them. Treatment is usually carried out at the end of September, October or even November.
Tip: Before spraying fruit from pests, it is important to protect the respiratory organs with a respirator and to wear goggles and rubber gloves.
Trees can be treated with hand sprayers and automatic sprayers. Spray the selected combination about 28-30 inches (71-76 cm) away from the tree. Wash your hands well after spraying.
During the growing season, various pests accumulate on the plant surface and in the recesses, crevices and cracks of the bark. You cannot extract them manually. If no action is taken, the insects will continue to overwinter on the tree and may attack them again in the spring. This is the reason why fruits need to be processed in the fall. Since the crop has already been harvested from them, chemicals that effectively treat pests can be used without the risk of being poisoned by one substance or another.
Let's take a closer look at how and what to spray apple trees in the fall to prevent diseases.
To treat apple trees for fruit rot, use a mixture of Bordeaux mixture at 3%. Treatment should be applied after the tree has shed 80% of its leaves. Depending on the region, this period is in late September, October or early November. It is important to apply the treatment at positive temperatures. Do not spray during or immediately after rain. Processing dry wood is recommended. Treat the entire above-ground part of the plant with the agent. In addition, you can spray the soil surface to loosen it slightly.
Treat under the same conditions as when protecting fruit crops from fruit decay. Spray from cytospora with a spore-destroying agent: copper sulfate (3%) or Bordeaux mixture (3%). Near stem areas are best treated with urea solution (7%) or ammonium nitrate solution (10%). It is important to complete the process before the start of frost.
Starting with apple tree cancer, it is important to start with a preventive treatment because it is extremely difficult to cure a dangerous disease. In the fall, usually in October, when apple trees shed more than 80% of their leaves, the plants need to be sprayed with a 3% solution of Bordeaux mixture or 3% copper sulfate. In this case, all wounds should first be disinfected by any means and then covered with garden asphalt or garden paint. You can also spray the soil surface with 3% Bordeaux mixture after loosening the soil.
Before treating the fungus, you need to make sure that the apple tree has shed most of its leaves and that the orchard is bare. You can then manually remove the fungus from conspicuous and accessible areas using a wooden scraper. Afterwards, you should use a mixture of 3% Bordeaux mixture or 3% copper sulfate and spray it over the entire above-ground tree.
Tip: It is recommended that the treated skeletal branches and bases be painted with lime dust.
To protect apple trees from scabbing in the fall, it is correct to use fungicides. You can spray the trees with other fungicides, but most gardeners use the same Bordeaux mixture or copper sulfate (3%)
After spraying the plants with Bordeaux mixture or blue sulfuric acid, you must brush the trunk with lime powder. Phytosporin can also be sprayed on the surface of the soil near the trunk band, after it has loosened sufficiently.
Not only is there a risk of crop damage from disease, but there are also various pests that may damage the crop and even destroy the tree. What are the ways to deal with various pests of apple trees in autumn?
Before winter arrives, silkworm plants can be treated with Malathion. This insecticide helps to deal with the caterpillar stage of the pest. Processing is done after harvesting and dumping most of the leaves. They can also be used to spray the soil around trees.
Tip: Malathion is a chemical insecticide. Use with care to protect exposed parts of the body, eyes and respiratory organs.
From bark beetle helper drug Bi-58. It is important to protect eyes, hands and respiratory organs when handling this product and make sure it does not harm bees as it is toxic to bees. When the entire crop is harvested and most of the leaves have fallen off, you can treat the above-ground parts of the apple tree and the near-stem zone.
From ticks, Malathion also applies. They spray the above-ground part of the plant. To prevent ticks, it is recommended to collect and burn the leaves and plant debris under the trees. Aphids rarely attack trees in autumn, but if the weather is warm for a long time in September, the risk of their appearance may increase. For aphids, dry weather apple trees are treated with Malathion, which nicely moistens the above-ground parts of the plant.
Spray the crop at various rates before overwintering, applying.
In order to treat apple trees with copper sulfate in autumn, use a solution with a 3% increase in concentration. This concentration means that 2.6 gals (10 liters) of water requires 300 grams of sulfuric acid. If efficiency is needed and a 4% solution is used, the amount of sulfuric acid increases to 400 grams. Processing was done in dry weather, positive temperature and without wind.
It is used after the leaves have fallen in dry and calm weather at positive temperatures. The concentration of the solution is usually very high: 5%-7%. To prepare a solution of this concentration in a bucket of water with a volume of 2.6 gals (10 liters), 500 or 700 grams of urea should be dissolved. The best month for treatment is November.
It is a mixture of 300 g of copper sulfate and 400 g of lime per barrel of water. If 1-2% Bordeaux mixture liquid is required, the amount of sulphuric acid is reduced to 100 or 200 g. Copper sulphate and lime are diluted separately and mixed, then the treatment is applied under calm winds and no rain.
Phytosporin is used to treat apple tree diseases in the fall. An effective biological fungicide usually in powder form. Consumption rate: 5 grams per bucket of water. Phytosporin must be well mixed, then fill the sprayer and properly process the above ground flora. Processing is done in dry, calm weather.
An effective but toxic insecticide. Most often comes in powder form. It is cultivated at a rate of 50 grams per bucket of water to treat an adult tree in the fall. It is important to remember that this is a chemical agent that is harmful to the health of bees and humans.
Before applying lime to the tree, the old stripped bark must be thoroughly removed, disinfected with any fungicide as well as Bordeaux mixture or blue sulfuric acid, and allowed to dry. Processing as well as lime dusting must be done after harvest and after most of the leaves have fallen off.
They are used strictly according to the instructions on the package. A good choice is a copper-based preparation.
Paint with slaked lime, optionally mixing it with iron or copper sulfate.
Tip: For whitewashing, choose the period with the least risk of precipitation, otherwise the rain will wash away the lime and the work must be redone.
Whitewashing techniques.
1. dilute 4.4 - 5.5 lbs (2 - 2.5 kg) of lime in a standard volume of 2.6 gals (10 liters) of water.
2. 250-300 gals of sulfuric acid is then mixed with the lime.
3. to form a complete stucco composition, 2.2 lbs (1 kg) of clay, 250 ml of acrylic paint and 120 g of casein gum are added to the mixture.
Treat the stem and base of the plant skeleton branches with the finished composition. The stucco was evenly applied with no variation in thickness.
