What is the best way to treat dill against aphids?

Aphids attack dill more often than other pests. Insects are attracted to lush green twigs. If measures are not taken in time, you can completely lose your green harvest. The peak activity of aphids occurs in May-June; it is during this period that people in their summer cottages begin to actively fight them using all possible means. Gardeners are faced with questions about how to get rid of aphids on dill using folk and chemical means and how to prevent infection.

Reasons for appearance

Dill is most often attacked by willow-carrot aphids. During the summer period, the insect produces up to 18 generations, and this becomes a real disaster for plants.

The main carriers of aphids are ants, which are attracted to the sweet, sticky liquid (honeydew) secreted by pests during their life processes. Ants not only organize feasts, but also protect aphid larvae and hide them in anthills for the winter. It is not difficult to guess that with the onset of summer the situation repeats itself again.

Reference. Winged individuals are able to migrate in search of new food.

Signs of infection

Aphids suck liquid from plants, and with it nutritional components. As a result, the branches wither, become deformed and dry out. Green growth slows down. If you carefully examine the greens, you can see colonies of green or black aphids.

Sweet honeydew, or honeydew, is an excellent medium for viruses and bacteria to attach and spread. The accumulation of sticky fluid stops photosynthesis.

Fighting methods

What to do if aphids eat dill? There are many options. To combat it, they use chemicals, biological products, folk recipes for decoctions and infusions, and agricultural techniques. You can also remove insects using water pressure, but this is only a temporary method. The aphids will return if you don't get rid of the root cause - the ants.

Each method has a detrimental effect on insects to a greater or lesser extent. To understand which one works more effectively, you will have to try it in action. The situation is complicated by the fact that aphids quickly get used to chemicals and do not always react properly to herbal preparations.

Fumigation

The tobacco fumigation method is used when growing dill in greenhouses. It is much more difficult to fight aphids indoors, and tobacco smoke completely destroys the pest without harming the plants.

In the greenhouse you will have to close all the windows, place an iron can in the center of the room, make a mini-fire from wood chips and pour out the shag. Then go out and close the door tightly. After the smoke has cleared, ventilate the room for 2-3 hours. The aphids die 24 hours after the smoke attack.
