Both the adults and immature stages are injurious to plants. Heavy infestations may cause severe economic losses. Reduce thrips populations by applying pesticides that are registered for this pest. Symptoms of infestation include chlorosis of the shoots, reduced plant vigor, and death. Infested roots contain fuzzy, white masses of eggs and females.
Prevention is the best method of control.
Discarding infested plants and drenching with a registered pesticide will help control root mealybugs.
