Companion® Max is a safe, 100 percent natural biological fungicide that both prevents and controls a broad spectrum of root and foliar diseases such as root rot, blight, wilt, bottom- and stem-rot, and bacterial leaf spot (Phytophthora, Pythium, Fusarium, Rhizoctonia, Sclerotinia and Xanthomonas campestris).

A patented Microbial Inoculant unlike any other product on the market, Companion Max contains the naturally occurring beneficial bacterium known as Bacillus subtilis GB03. The GB03 isolate combats disease pathogens though multiple modes of action. It quickly colonizes a plant’s root hairs and literally crowds out disease producing microbes in the soil; it produces antibiotics that disrupt the cell wall formation of pathogens, causing the pathogens to desiccate and die; and it creates a beneficial Induced Systemic Resistance (ISR) whereby plants’ own natural immune system is stimulated to better resist diseases. Used alone, in combination with, or in rotation with chemical fungicides, Companion Max can serve a crucial role in a grower’s disease resistance management program.

Companion’s GB03 also acts a Plant Growth Promoting Rhizobacterium (PGPR) and bio–Enhancer. It naturally encourages plant growth and produces better rooting, branching and flowering on plants.

Companion’s safety level as a fungicide is unsurpassed. It has a low 0 – 4 hours REI for workers, is non-toxic to beneficial insects, and has no phytotoxicity for crops.


Companion Microbial Inoculant is also available as a wettable powder.
