Pests
Cymbidium’s enemy number one is the red spider mite. Symptoms are tiny white dots on the undersides of the leaves, giving an overall silvery appearance. Control using a miticide, following the recommended dosage. Enemy number two is scale. These resemble tiny brown umbrella-like structures on the upper surface of the leaves. Use a garden insecticide that lists scale; repeat application three times a day at ten day intervals. The third most frequently encountered pests are aphids. They are usually noticed on the buds and flowers and can sometimes be discouraged by wiping the colonies off by hand, or by misting them off with water. Use mild rose or flower sprays, or the garden aerosols. Apply lightly but thoroughly; excessive applications to the buds can result in burning. Finally, snails and slugs are as pervasive as garden pests can be. Fortunately, they are easily controlled through a conscientious baiting program. Not all snail baits control slugs and sow bugs however, so read the label carefully
