Microbial is a wide-ranging aqueous solution derived in part from naturally occurring plant extracts. Microbial is non-toxic to humans, animals and plants and is totally biodegradable and environmentally friendly. Microbial acts as a micro-cleanser and plant conditioner, which cleans and rejuvenates plants. This allows the plant to naturally withstand attacks from common pests and biological contaminants like bacteria, fungi, algae and viruses.
