Southern Ag Natural Pyrethrin Concentrate, like most insecticides, is not specifically tested or labeled for use on marijuana plants so we cannot comment or recommend it for this use. Customers will need to make their own decision as to what they consider safe. Some of these products are natural and organic and others are not. Some products, like the miticides, probably shouldn't be used when the plants are flowering. You may also try reaching out to the manufacturer for advice.
