I'm new to keeping having plants at home and had no idea the care that some required. I have a huge dumb cane plant that started getting these little spots and powdery finish on the leaves for no apparent reason. After doing some research it's a type a insect that is common to that plant that needs to be treated often with an Insecticidal Soap before it kills the plant & maintained with garden control to protect. I picked this brand up hoped for the best. It worked to well! I followed the instructions, sprayed all the leaves in both sides and in two days the plant looks restored to health. Now I spray it once every two weeks since I moved the plant outdoors. It's been 15 months since I started using this and my plant has remained healthy.
