Chrysanthemum rust is a pest of chrysanthemums that settles on the leaves in the form of greenish-white or yellow spots.
The "imperial flower", the chrysanthemum, cannot be missing in a garden. As a busy autumn flower, it is just as popular as gladioli. The white chrysanthemum rust is a pest that can damage chrysanthemums.
Chrysanthemum Rust
The white chrysanthemum rust is noticeable by greenish-white or yellow spots on the upper side of the leaf. The mealy fluff on the underside of the leaf must be treated with a special fungicide.
If you also have roses with pests, you can use the "rose spray" from specialist shops for both plants. The plants should be sprayed three times at intervals of 8-10 days, because this way you can eradicate the pest.
Don't plant chrysanthemums too close together
To avoid this procedure, do not plant the chrysanthemums too close together. This ensures that the leaves of the flower are not too close together and can dry out faster.
Chrysanthemum rust can only occur if the plant leaves are constantly wet, allowing the fungus to develop. Spider mites can also be treated in this way. However, the treatment must be repeated again and again so that the mites that hatch later are also recorded.
