The appearance of aphids on a plot is a big problem for any summer resident.
However, these parasites spread quickly, sucking out all the juices from plants, which ultimately destroys flowers, fruit bushes and reduces the yield of vegetables and fruits in season.
Therefore, it is necessary to periodically carry out preventive treatments and inspect plantings for the presence of insects.
As gardeners note, most preparations are effective for no more than three weeks after treatment. Some products may have a shorter period of action.
Therefore, it is important to strictly follow the instructions during processing.
If you have treated the garden twice during the season, but it still appears, then you should not be alarmed.
This is natural, since the poison has dispersed and lost its effectiveness.
For this reason, it is necessary to repeat the treatments periodically. In this case, the pest does not threaten the garden.
