Leaves and flowers damaged by aphids sucking the contents of plant cells are distorted and yellowish. Aphids secrete a sweet substance called honeydew. Falling down, falling on lower leaves, "sticks" them, thus limiting photosynthesis and negatively influencing transpiration. This process is exacerbated when so-called seed fungi begin to develop on the honeydew, covering the leaf with a dark brown coating.Aphids are also carriers of the viruses and lureants that feed on their honeydew and protect the aphids from natural enemies. The color of the aphids varies from light beige to black.The body length of an adult insect varies between 1.7-3.6 millimeters. After the first aphids appear, the bushes should be sprayed with preparations, for example, Calypso 480 SL, Mospilan 20 SP, and in the period when the temperature drops below 20 ° C, with Decis 2.5 EC or Talstar 100 EC.
