Developed from a naturally occurring bacteria, Streptomyces griseoviridis, LALSTOP® K61 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, giving your plants a strong start for vigorous growth and development. Streptomyces deprives pathogenic fungi of space and nourishment by colonizing plant roots, where it also acts as a hyperparasite, disrupting cell walls of pathogens and producing metabolites that further inhibit and disrupt these pathogens.
- Organic & 100% natural
- Based on a naturally occurring, live bacterium (Streptomyces sp. strain K61) that readily colonizes roots for extended protection.
- Use on all crops such as medicinal herbs, vegetables and ornamentals
- Can be used simultaneously with nematodes and other biological control organisms, compatible with most IPM programs (see Compatibility Guide below)
- Control or suppression of many root rot and wilt pathogenic fungi, such as Pythium, Fusarium, Alteraria, Phomopsis, Phizoctonia, Phytophthora and Botrytis
- Ideal for Hydroponics, solves most root rot issues
- Works equally well in organic, mineral and artificial growing media, and field soils
- Easy application by drench, surface spray or through hydroponic delivery
- No known risks for resistance due to multiple modes of action
- Safe to apply, regardless of plant maturity/stage
- Leaves no toxic residues
- *Ships as 10x 100 gram packets*
LALSTOP K61 is used by growers for disease caused by Pythium, Fusarium, Rhizoctonia, Alternaria, Phomopsis, and to a lesser extent for Botrytis and Phytophtora. LALSTOP K61 has particularly good activity against Fusarium, and is increasingly used as a seed treatment for Pythium, Fusarium, and other seedling pathogens.
LALSTOP K61 has been shown to increase plant vigor and yields even in the absence of obvious root pathogen activity, as the Streptomyces produce plant root stimulating hormones that benefit plant health overall.

Super easy to use because you actually get 10 of the 100 gram packs instead of one huge bag. Much easier to deal with if you're not going to use the whole 1000 grams at one time.
Best price we have found and they ship expedited. We usually have it in 2 or 3 days. The answer for pythium instead of chillers for hydroponic recirculating systems like DWC or ebb+flow. Cloners will benefit too.
Gracias por la intención dada. El pedido llego en perfecto estado, lo estamos usando después de 1 semana y se nota mucho la calidad que tienen nuestra plantitas.
The instructions are very clear. The package arrived in perfect condition and on the promised day.
Increíble la experiencia de compra con Vivagrow, solicite alguna información por que tenia unas dudas y me atendieron sin duda. Funciona de maravilla para nuestro hidro cultivo. Nuestras plantas de cannabis nunca habías estado tan bien. Gracias nuevamente
Wow! de verdad es increíble la facilidad y la simplicidad en la que ayuda de manera enorme a mis cultivos. Las especificaciones del producto son las correctas y no tendrás falla, eso si me gustaría que fuera un poco mas grande la bolsa. Pero de ahí en fuera se puede resolver, no duden en comprarlo de verdad
Increíble valor por su precio, sin duda uno de los mejores productos en el mercado, necesito más!
Symbiosys Grow came and helped us diagnose a disease problem that we are having. The problem is Pythium it turns out. So now we are using this K61 biological for prevention and have not had any sick plants since starting this. It is a living organism that lives in the plant roots and crowds out other diseases. It also makes beneficial enzymes that increase yield, so it will pay for itself! 5 stars for K61 and 5 stars for Symbiosys Grow.
Incredible value if you use alot of biofungicide. Our shop has 12 rooms with 350 gallon deep water culture hydro systems in each one. This bulk pack makes it affordable to treat everything all the time. Ask for details about how to use it and they will give you a bunch of real world info they have grown cannabis professionally so they are not just guessing like other places online. They have a PHD plant disease guy too so they know what they are doing.
