We save viburnum from aphids
Lush viburnum bushes are widely used in landscaping. They are beautiful at any time of the year: covered with beautiful green leaves, delicate white inflorescences or red fruits, viburnum becomes a decoration of the site. However, even she is not immune from the attack of pests, which cause significant harm to the shrub. Most often, viburnum is attacked by aphids - a very small, but terribly harmful insect.
How to recognize aphids?
The black aphid loves viburnum most of all. They are small, dark brown insects with high fertility. They lay eggs on the bark near the buds, from which larvae emerge in spring. The larvae begin to eat tender young leaves, and the bush stops developing. If you do not start an immediate fight, adults will lay many new eggs in the fall, and everything will be repeated in the spring.
Viburnum affected by aphids can be easily distinguished from other plants: first, an accumulation of insects appears on young shoots, then the leaves curl, and the bush stops growing.
Folk remedies against aphids
Aphids on viburnum must be destroyed at the very beginning, until it begins to multiply. In the initial stages will help folk methods, such as spraying:
- Soapy solution... Dissolve 300 g of grated (household) soap in a bucket of water and carry out 3 treatments within a week. Wash off dead insects under pressure from a hose.
- Tobacco infusion... Pour 250 g of tobacco on 5 liters of water, leave for two days. Strain and add another 5 liters of water.
- A solution of ammonia... Pour 20 ml of alcohol into a bucket of water. Process twice with a break of two weeks.
Before proceeding with processing, regardless of the method used, it is necessary to destroy young root shoots on the viburnum, where the aphid prefers to lay eggs.
Aphid preparations
If the moment is lost and aphid has already actively filled the entire bush, more effective means will be needed. Among the special preparations for pests, they have proven themselves well:
- Akarin.
- Fufanon.
- Arrivo.
Preventive actions
To prevent the appearance of aphids on the viburnum, it is necessary every spring to clean the bush from the old flaking bark, under which there may be masonry, and whitewash the trunk with lime. You should also regularly cut out root growth and tops.
If there are ants in the garden that contribute to the development of aphids, it is necessary to get rid of them by spilling the places of accumulation with boiling water. But some insects, such as ladybugs, should, on the contrary, be attracted to the garden, since they eat aphids.
