And will the powder adhere to both top and bottom of the leaves?
Organic Diatomaceous Earth and does not have specific labeling for mites such as spider or russet mites. DE is a dry powder and will be removed with rain or watering on treated plants. While the dust could potentially kill insects contacted with the dust, it can take many days for insects to die from diatomaceous earth, so it is likely that you would not get the results you desire. Monterey Fruit Tree Spray Plus is a popular product for spider mites and similar insects on edible plants. Avid is one of our most popular miticides for ornamentals.
