Here there is an infestation of whitish yellow spots on the leaves. These spider mite eggs, which overwinter on the plant, can be combated with agents containing rapeseed oil and mineral oil. This can be followed by a treatment with the above-mentioned agents against sucking insects.

An infestation can first be recognized by brown spots on the leaves, black longitudinal stripes on the shoots of the plant and white spore beds on the underside of the leaves.

It is important that leaves on the ground are completely removed and disposed of, as the plants could otherwise become infected again through the fungal spores. The scissors should then be disinfected. The new shoots, after about 2 weeks, can then be treated preventively with a fungicide.

As the process progresses, the initially green leaves become lighter and lighter and finally dry up. In addition, growths and pink mushroom beds form on the shoots.
