After harvesting, it is important to devote attention and time to treating trees in autumn before winter. This will protect them from pests and disease pathogens, which also overwinter in order to become active in spring. AgroKhim Company has collected the main useful tips on autumn garden treatment for you, as well as the best preparations against pests and diseases.
The importance of autumn protection for garden trees
It is not only fruit trees that prepare for winter. Harmful insects searching for a winter “home” hide in plant debris — in piles of leaves, fallen fruit or branches, in the soil beneath trees and even under the bark.
Fungi also survive winter in infected soil and in “mummified” fruit and leaves left on the tree. During the season, spores are spread by the wind and settle literally everywhere. They are not noticeable at first, but in spring they will awaken first and infect the tree buds.
Proper garden treatment in autumn will help avoid many problems and make a successful start to the new gardening season.
General rules for chemical treatment of fruit trees
Success depends on starting the work on time. Treatment should be scheduled for windless weather without precipitation (preferably for several days). It is also important to remember that the preparations work at above-zero temperatures, so spraying is carried out before the first frosts — until mid-October.
Other treatment rules to improve the effectiveness of chemical spraying:
- strict adherence to dosages — an excessive dose will harm the trees, while an insufficient one will have no effect;
- treating not only the crown and branches, but also the soil around the trunk, as insects and fungal spores may hide there;
- clearing the soil of organic residues and digging it over;
- cleaning old and damaged bark and lichens from the trees;
- pruning dry branches and treating wounds and cracks — infection may develop in them.
Chemical treatment against pests
Choose broad-spectrum insecticides.
Preparation 30V is an insectoacaricide that eliminates overwintering stages of pests. This chemical creates a barrier, blocking air from reaching insect larvae and eggs. It is applied at temperatures up to +4 ⁰С after the trees shed their leaves.
Aktara is a preparation based on thiamethoxam. It provides protection for 28 days when sprayed and 60 days when applied by watering. It is used after harvesting and is compatible with other chemical preparations for fruit crops.
Disease prevention
The main measure is fungicidal whitewashing with compounds containing lime and clay. This will protect against diseases as well as rodents, some insects and frost. In spring, the trees will also not suffer from sunburn.
The following preparations are effective:
- Bordeaux mixture is a copper-based preparation that is fatal to pathogens, but it can be applied only after the leaves have fallen, when the tree becomes dormant;
- iron sulfate is suitable for preventing fungal and bacterial diseases and is compatible with most insecticides.
Autumn treatment of fruit trees is the best way to restore and protect plants and prepare them for the next season. It will also make spring treatment easier and ensure a higher-quality and more abundant harvest.
