Here The major arthropod pests of Chlorophytum include caterpillars, root mealybugs and scales. Mealybug and scale infestations are typically the result of introducing infested plant material into the greenhouse. In the control section for each pest, a few of the many registered and effective pesticides will be listed. For a complete listing, please consult the references at the end of this note. Symptoms - Infestations are easy to detect because worms, their excrement and the damage they cause, are usually quite visible to the unaided eye.
Damage appears as holes in the center or along the edges of leaves.
Mealybugs Symptoms - Mealybugs appear as white, cottony masses in leaf axils, on the lower surfaces of leaves and on the roots. Honeydew and sooty mold are often present and infested plants become stunted, and with severe infestations, plant parts begin to die. Control - Systemic materials are preferred. Control of root mealybugs is accomplished with soil drenches with an insecticide. When pesticides are applied to the soil, care must be taken to assure that the pots have good drainage and that no saucers are attached, or phytotoxicity may result.
