If you notice yellowing of chrysanthemum leaves on your plants, it could be a sign of a problem in some way. For example is the soil. Look at the soil on your chrysanthemum plant. Generally, plants need well-drained soil to thrive including chrysanthemums. If the soil does not absorb water well or has a poor drainage system then the root growth will be disrupted and the leaves on your chrysanthemum plant will turn yellow.

Pear-shaped sucking insects, aphids are no larger than a pin head, but aphids rarely travel alone. These insects often gather in large numbers at the tips of stems and shoots of plants.
Well, if you see a yellowing of chrysanthemums, check to see if these plant lice are present. Fortunately, you can eliminate the problem aphids cause with chrysanthemums by picking the full, yellow leaves on the chrysanthemums and throwing them in a plastic bag in the trash.

Aphids attack can reduce the quality of chrysanthemum flowers. To control this pest, farmers usually use synthetic insecticides which are commonly sold in the market.
However, synthetic insecticides are often used unwisely, resulting in various negative impacts including the occurrence of pest resistance to insecticides, the emergence of pest resurgence (explosion) and the occurrence of secondary pest explosions, besides being able to cause environmental pollution and kill natural enemies, it can even cause poisoning in humans and animals.
One of the plants that has the potential to be developed as a vegetable insecticide in leaf pest control is the genus Toona (suren) which belongs to the Meliaceae family and has not been widely used.
Suren plant (Toona sureni) has the opportunity to be used as a vegetable insecticide because of its abundance.
Suren contains active ingredients that are insecticidal, the extract can control beetles on wheat.
