Leaf twisting (seen here on Dracaena plugs), distortion, chlorosis and spotting can be caused by improper use of the pesticide Judo. These plants are expected to eventually grow out of the injury. Judo is an insecticide and miticide labeled for mites and whiteflies. It is currently being used by growers to manage Q-strain biotype whiteflies on poinsettias. According to the Judo Technical Bulletin, Judo is not recommended for use on Dracaena and other spring crops and tropical foliage plants. For details on preventing injury and for a list of crops, follow label directions and see the company's technical bulletin (PDF).
