The following is the pest control of Ruixiang flowers, let's go and have a look!

First, how to do when the Ruixiang flower grows worms, spray with medicine

Although Daphne odorifera has strong disease resistance, it will also have insect pests and occasional diseases in the case of poor growth environment and improper maintenance.

Disease symptoms: the damaged leaves of Daphne odorifera showed color spots and deformities, resulting in poor flowering and stagnation of plant growth.

Prevention and control methods, diseased plants should be removed in time to reduce the source of the disease. When the disease is serious, 50% methyl topiramate 1200 times foliar spray can be used for disinfection to prevent transmission.
