ROSE TIPPER (Edwarsiana rosae) is an insect with a delicate, slender body structure, up to 4 mm long. The larvae are light yellow. They overwinter under the skin of young rose shoots. The larvae feed along the veins of rose leaves on their undersides. Adult insects fly to apple trees, where the second generation develops. At the end of summer, the females return to the roses, where they lay eggs in the shoots.
Symptoms
As a result of this pest feeding on the underside of the leaves, the upper side becomes covered with small white spots. At first they appear along the main vein, and over time all the leaves turn white and fall off. Small light-colored insects can be seen on the underside of the leaf.
Host plants
Most types and varieties of roses and apple trees.
Control methods
Having noticed the first damage, the plants should be sprayed with chemicals, for example, Karate Zeon 050 CS. In the spring you need to cut off the shoots and burn them.
