How to deal with currant leaflet?
Currant is grown almost everywhere, as it is a very unpretentious and at the same time tasty berry. But not only gardeners love to feast on her, but also all kinds of pests. Huge damage to currant bushes can be caused by insects called leafworms, which are very difficult to remove from the garden. To know how to deal with a leaflet, as well as what methods are best used, you need to consider a lot of nuances about this, as well as read the advice of specialists.
What does it look like
It is very important to know the appearance of the "enemy" in order to choose the right means to destroy it. Leaf rollers are butterflies, the varieties of which are about 10 thousand. They are distributed all over the globe, our country is also no exception. Leaf rollers do not manage with currants alone, they also love other berry and fruit crops that sprout in the garden. Adult individuals of leafworms outwardly resemble moths, their wings are folded horizontally. They have a gray-brown color with dirty stains on the front wings. Moths of the leafworm species have a very short life, since the main purpose of their existence is the laying of eggs. Butterflies themselves are not dangerous for plants, since they do not feed on them, but their offspring can cause serious harm to currants.
If butterflies matching the description were seen on the plants, then it would be best to inspect the bushes, because leafworm caterpillars can sit on them.They have a naked transparent body, the color of which varies from yellowish to light green, depending on the age of the individuals. The head is red-brown, the caterpillars have 16 legs, thanks to which it is not so easy to drive them out of the plants.
Newly born caterpillars are only a few mm in size, but already grown ones can be 2-2.5 cm. These caterpillars are nicknamed leafworms because they twist the leaves of plants and then feed on them. Also, the caterpillars tangle the leaf with the help of a web, creating a kind of dwelling for themselves there.
One caterpillar is unlikely to spoil the whole plant, but given the fact that they appear very quickly, a huge number of caterpillars can easily leave gardeners without a crop. Leaves damaged by caterpillars, as a rule, turn black, become covered with holes, and then fall off. As a result, the flowers do not develop, and the fruits do not ripen.

Biological agents can also be used during the harvest, since most of them are harmless to humans and the environment. As for chemicals, more precisely, insecticides, almost all of them have an instant effect, destroying caterpillars immediately.However, chemicals should not be used frequently, as they have a cumulative effect, in addition, not all of them can be used when caterpillars attack an already fruiting bush.
Experts warn novice gardeners, saying that in nature there is a type of leafworm that can even eat up the root system of fruit crops.

Of course, the taste of the juice that they eat from the leaves becomes unpleasant for the caterpillars. To prepare this solution, mix water, laundry soap and wood ash. Soap does not need to be added for watering under the root. Spraying plants is best done once a week. Watering can be done once in November and early spring, after having spudded the bush.
