October is the time when trees prepare for winter and need special care.
One of the important measures is the treatment of trees from pests that can cause serious damage to them.
Why is it necessary to treat trees in October
In October, there are still leaves on the trees, under which eggs, larvae and adult pests can hide, reminds the expert of the online publication "BelNovosti", agronomist and landscape designer Anastasia Kovrizhnykh.
If they are not destroyed, they will overwinter on trees and continue their destructive activity the following year.
Treating trees in October helps prevent the development of diseases caused by fungi and bacteria, which can also overwinter on trees.
In addition, treating trees helps them heal and strengthen before winter frosts.
What preparations to use for treating trees
To treat trees in October, you can use various preparations, which are divided into chemical and biological.
Chemicals are more effective, but they can have a negative impact on the environment and beneficial insects. Biologicals are safer, but they require more frequent use and do not always cope with severe infestations.
Among the chemical preparations, the following can be distinguished:
Copper sulfate is a universal product that kills fungi, bacteria and some pests. It is dissolved in water and sprayed on trees after the leaves have fallen.
Iron sulfate is a product that effectively combats fungal diseases such as scab, moniliosis and rust. It is also dissolved in water and sprayed on trees after the leaves have fallen.
Malathion is a product that kills most types of insect pests, such as mites, scale insects, scale insects and aphids. It is diluted in soapy water and sprayed on trees before the leaves fall.
Among the biological preparations, the following can be distinguished:
Bitoxybacillin is a product that contains live bacteria that cause disease in caterpillars, worms and other larval forms of pests. It is dissolved in water and sprayed on trees before the leaves fall.
Fitoverm is a product that contains a substance that paralyzes the nervous system of insects. It is diluted in water and sprayed on trees before the leaves fall.
Lepidocide is a product that contains spores of a fungus that attacks caterpillars and other pests. It is diluted in water and sprayed on trees before the leaves fall.
How to properly treat trees
In order for tree treatment to be effective, the following rules must be followed:
• Select preparations in accordance with the type and degree of tree infestation.
• Observe the dosage and duration of use of the drugs indicated in the instructions.
• Treat trees at temperatures not lower than +5°C and not higher than +25°C, without wind or rain.
• Treat not only the crown, but also the trunk and root zone of trees.
• Use protective clothing, gloves and glasses when working with preparations.
• Do not consume fruits from treated trees within 30 days after treatment.
