Developed from a naturally occurring bacteria, Streptomyces sp. strain K61, LALSTOP® K61 WP is a preventative product that thrives in the rhizosphere for several weeks and provides effective control on a wide range of pathogens including damping-off caused by various fungi, such as Alternaria and Rhizoctonia solani; and wilt and root diseases caused by Fusarium, Phytophthora and Pythium. When applied as a drench or spray, the dried spores and mycelium of the Streptomyces culture in LALSTOP K61 WP germinate and begin to grow on and around the plant root system. This creates a biological defense against seed and soil-borne pathogens.
