Aphids on dill are more common than any other harmful insect. The pest is attracted by juicy leaves and stems of greenery, the juice of which they feed on. With improper crop care, plantings are quickly affected by aphids and do not have time to grow normally. You need to solve the problem with an insect as quickly as possible so as not to be left without fresh greenery in the summer.
Reasons for the appearance of aphids on dill
In most cases, ants are the cause of insects.... They carry aphids on site and leave them on succulent plants. Ants not only protect aphids from other insects and feed on its sap, but also carry bugs into their nests in winter. Therefore, with the onset of spring, aphids appear as if out of thin air.
How to determine what aphids are on dill
It is easy to get ahead of the fact that aphids have appeared on the beds with greenery. When there are too many insects, it can be seen with the naked eye. It is enough just to inspect the greenery and see a cluster of small green bugs on it. Distributed on crops, they prefer colonies.
The first signs of aphid infestation are the yellowing of the leaves and their drying. Aphids feed on the sap of the stems and gradually they begin to become withered.
After themselves, insects leave a discharge on the bushes, which is called a span. The spade has a sweetish taste and honey aroma. In turn, this attracts other harmful parasites and contributes to the development of fungal diseases.
You can fight aphids using various methods. There are several main ways:
- Using folk methods.
- With the help of modern biological products.
Each method of struggle has its own nuances of application, as well as advantages and disadvantages.
Folk remedies to combat aphids
Before resorting to aggressive chemical pest control methods, you need to try safer folk remedies than you can handle the plant. They are not harmful to health and are considered one of the safest. But they do not always differ in effectiveness, unlike herbicides.
