Aphids awaken and begin to cause harm immediately after the first signs of bud swelling appear.
When the first leaves bloom, aphids immediately begin to feed on the sap and spread viral diseases.
Therefore, summer residents try not to miss the moment when plantings can be successfully treated in order to prevent aphids from multiplying and seriously harming shrubs and trees.
There is no specific calendar date, as everything depends on weather conditions. The signal that it is time to act is the swelling and blossoming of the buds.
Any broad-spectrum insecticide is used. For example, for aphid treatment, use "Aktara", "Decis", "Fufanon", "Voliam".
Gardeners try to get rid of aphids early to forget about the pest for a long time. However, the quality of the work done depends on following all recommendations for the use of pesticides.
It is important not only to prepare the required concentration, but also to choose the right time of day. The ideal time for processing is evening or morning in windless weather at +6 …+10 °C.
