Plum pollinated aphid and other varieties
In nature, there are many types of aphids, which to some extent damage the garden and garden plantations. For plum, cherry, cherry plum, sweet cherry, apricot, peach and other stone fruit crops, one of the most dangerous pests is plum pollinated aphid.
Small grayish-green insects settle on leaf and flower buds, on young growth and on the back side of already opened leaves. With mass infection, these parts of the plant are completely hidden under a layer of pests and dead whitish scales. Feeding on the juices of the most tender greens, the aphid causes:
- weakening of the shoots becoming a desirable prey of other pests and stronger than others suffering from lack of food, cold of desiccation;
- deformation of young leaves, taking the form of a spoon or boat;
- mass destruction of the fruit plant with soot fungus and pathogens;
- early fall of foliage and poor preparation of trees for wintering;
- yield reduction in this and subsequent season.
While the warm period lasts, pollinated plum aphid can give a dozen generations. At the same time, insect eggs survive the winter not only in the cracks of the bark, but also on the nearest grasses, preferring grasses and reeds.
A green aphid on a plum becomes noticeable when the number of insects is critical. But to find a black, cherry variety, not abhorring other types of stone fruit cultures, is much easier. This pest, giving up to 14 generations, no less dangerous. Damage to them leads to a complete collapse of the tips of young shoots, the cessation of their growth and development of foliage.
All kinds of aphids are dangerous in that they can spread rapidly. Winged individuals migrate on their own, and ants, literally pasturing in the hunt for the sweet secret of insects, migrate the wingless from plant to plant.
Defeating a garden with this soft-looking pest can lead to weakening of trees and crop loss. How to deal with aphids on plum? When and what measures should be taken to maximize the effect?
