To deal with the currant leaflet, you need to start in the late autumn after harvesting, or early in the spring, until the leaves bloom. During the growing season, the use of chemicals is allowed no later than 25 days before harvest. During flowering, exclusively folk methods of struggle are used.
The appearance of the pest
Leafworms are butterflies, including about 1 thousand genera and more than 10 thousand species. Distributed around the world, hit the apple trees and other garden crops. Currant suffers from the attack of pests.
Butterfly or moth - an adult. Outwardly resembles a mole. Wingspan not more than 25 mm, folds horizontally. Coloring in gray-brown tones with stains on the front wings. The moth lives a short life, the main task is to lay eggs, give life to a new generation. Butterfly does not harm the plant, because it does not eat anything.
On a note!
The main enemy is the leaflet larva - caterpillar. The body is naked, the color is yellowish or greenish. The head is brown, almost red in color. 16 legs allow the pest to hold well on leaves, branches, crawl along the crown in any direction.
Caterpillars feed leaves with a huge appetite. About 2 mm in size are born, but already in 20 days of development they reach a length of 2 cm. The larva twists a leaf, tangles with a cobweb, forms a kind of house where it hides from enemies, sunlight. A photo of the currant leaflet is presented below.
One caterpillar will not cause much harm to currants, but given their massive birth and "brutal" appetite, the extent of the damage is easy to guess. Damaged leaves curl, blacken, fall off, flowers do not develop, fruits do not form. A young bush can simply dry out.
On a note!
