Two Big Announcements for Actinovate®!

Novozymes is announcing two new developments for Actinovate® biological fungicide: All Actinovate® products will now feature a two-year shelf life, and Actinovate® Lawn & Garden is now available in 2-oz. packaging.

Grants Pass, OR, April 5, 2023: Mycorrhizal Applications, LLC (MA), a distributor of Actinovate® biological fungicide in the Horticulture Industry, is pleased to announce two new developments for the Actinovate line of products.  Effective April 1, 2023, all SKUs within the Actinovate® brand of products will be distributed with a two-year shelf life. This doubles the previous shelf life – a key benefit to distributors, retailers, and ultimately end-users who seek a dependable product adapted to various handling and operational situations.  This newly extended shelf life makes these practical and effective biological fungicide products even more convenient for retailers and growers. Actinovate® will now have one of the longest shelf lives of any product of this type, and still requires no refrigeration, special handling, or complicated storage guidelines.

In addition to the extended two-year shelf life, MA is also excited to announce the return of the 2 oz. packaging for Actinovate® Lawn & Garden.  Back by popular demand, Novozymes has revived the 2 oz. SKU, which was extremely popular for home lawn and garden use, as this packaging size of the powerful Actinovate® biological fungicide is ideal for retail settings.

Actinovate® is a unique biological fungicide based on the beneficial soil bacterium Streptomyces lydicus WYEC 108 and is used to combat fungal plant pathogens such as damping off, root rot, turf brown patch, gray mold, downy mildew, and powdery mildew.  Actinovate® SP is available in 18 oz. packages from most major horticulture distributors in the US, and is labeled for professional use in greenhouses, nurseries, landscaping, and other applications.  Actinovate® Lawn & Garden is labeled for home garden and turf use and is available in retail stores and garden centers across the US in the new 2 oz. packaging as well as 18 oz. package sizes.  Actinovate AG has a broad and flexible label for use in multiple industries and is available in 5 lb. bags.

“With the change to a two-year shelf life and the re-launch of the 2-oz. Actinovate® Lawn and Garden packaging, Actinovate® now undoubtedly offers the most practical biological fungicide product line available to growers and retailers,” stated Blair Busenbark, Sales and Commercial Marketing Manager at MA. “Actinovate® offers a broad spectrum of performance as both a foliar and drench fungicide which can now be stored for up to two years from the date of manufacture under standard warehouse conditions. With this shelf-life improvement and the availability of 2-oz. packaging, Actinovate® becomes much more practical as a retail product for garden centers to carry on their shelves, as well as an even more valuable tool for a professional grower’s Integrated Pest Management toolbox.”

Actinovate Product Overview:

Actinovate biological fungicides offer growers and home gardeners a very powerful and versatile Organic (OMRI Listed) tool to control fungal pathogens.  Actinovate works just like other biological controls (the classic example of biological control is the use of ladybugs to control aphids), only the organisms in Actinovate do their work on a microscopic level.  Actinovate uses a natural enemy of fungal pathogens to keep these pathogens from destroying your crops.  This natural enemy is a beneficial bacteria called Streptomyces lydicus WYEC 108, which is a naturally occurring soil bacterium that was originally isolated from the roots of a linseed plant in England, and patented worldwide.  Actinovate is effective and versatile, utilized both indoors and outdoors, in markets including greenhouses, nurseries, landscaping, turf, and homeowners.

Key Features:

  • Now shelf-stable for 24 months after the date of manufacture.
  • Although the product is based on live biological organisms, it can be stored under normal warehouse conditions.
  • Actinovate controls a diverse number of soil and foliar pathogens.
  • These products can be applied as a foliar spray and/or soil drench.
  • Actinovate is non-phytotoxic.
  • The biological active ingredient in Actinovate poses no threat of pesticide resistance formation.
  • Can be used as part of an IPM protocol and/or in rotation with traditional chemical fungicides.
  • Actinovate has a low Re-Entry Interval (REI) of 4 hours.
  • No Pre-Harvest Interval (PHI) – can be applied up to and including the day of harvest.

How does Actinovate protect against fungal pathogens?

Actinovate can be utilized to combat fungal soil diseases, as well as foliar diseases.  The organism within Actinovate colonizes plant structures in a beneficial symbiotic manner when introduced into the root zone or applied to foliage.  The Streptomyces lydicus spores germinate and form a mutually beneficial relationship within the rhizosphere of plants by feeding off the plant’s waste and secreting beneficial byproducts, such as Chitinase to break down fungal walls, byproducts that kill or repel other microbes, and iron carriers to starve competing microbes.  Essentially, the S. lydicus feeds off the root’s secretions and discharges toxins that keep other microbes (including pathogens) out.  This assortment of byproducts and toxins discharged by S. lydicus means that Actinovate utilizes several modes of anti-fungal action to protect plants, lawns, and gardens from pathogens, rather than relying on a single mode of action as many other fungicides do.

What pathogens can Actinovate help control?

Similar to a probiotic used to keep our own digestive systems in healthy balance, Actinovate works within the root zone microbiome to keep the system healthy and in balance.  Actinovate can be used on annual and perennial bedding plants and flowers, roses, potted flowers, foliage plants, trees, shrubs, and lawns located in homes, greenhouses, and home landscapes, as well as fruits including tree fruits, berries, and melons, nuts including a wide variety of tree nuts, and vegetables including leafy vegetables, root crops, cole crops, peppers, and tomatoes.

Actinovate’s S. lydicus organism will actively control several common soil pathogens, such as Damping Off Fungus, Root Rot, Turf Brown Patch, Pythium, Rhizoctonia, Phytophthora, Fusarium, Verticillium, Sclerotinia, and many others.

In foliar applications, Actinovate will suppress Downy Mildew, Gray Mold, Powdery Mildew, Botrytis, Phytomatotricum, Sclerotinia, Alternaria, and more.

When should Actinovate be applied?

As with most biological controls, it is best to use Actinovate as a preventative tool, rather than curative treatment.  For best results, apply Actinovate as early as possible to the plant’s root system, and reapply every 2-12 weeks as needed.  In foliar applications, it is best to apply prior to disease development, or at the first signs of pathogen infection, and repeat at 7-14 day intervals to protect new foliage.

Actinovate is relatively safe, though caution is advised when using any pesticide.  Please read the label thoroughly for all precautionary statements and PPE requirements.  When sprayed onto foliage or used in chemigation via sprinkler or other spray irrigation, the re-entry period is only one hour, or once the solution has dried.  Actinovate can be applied up to and including the day of harvest, so the pre-harvest interval is not a concern.  Always clean application equipment prior to use of this product, and use the prepared Actinovate solution within 4 hours of preparation.

How can Growers and Gardeners apply Actinovate?

Actinovate is a soluble powder that can be added to water to create a solution and then applied to the plant’s root zone or foliage using the applications below.

For rhizosphere or root-zone applications, the soil drench should contain 4-6 ounces of Actinovate per 100 gallons of water (1 teaspoon per 2 gallons of water for smaller quantities).  This solution can be watered into damp soils, applied to pots, the base of plants, root balls, or applied to the root zone by watering the substrate with Actinovate solution until the soil is completely saturated without creating runoff (generally 1 gallon of solution per cubic foot of substrate).  In greenhouses and nurseries, Actinovate can be applied to the root zone via drip or flood chemigation using the rate of 1-12 ounces of Actinovate per 10-200 gallons of water, depending on the desired application.  For soil chemigation, apply the solution only through pressurized drench (flood) or drip (trickle) systems, micro irrigation such as spaghetti tube or individual tube irrigation, hand-held calibrated irrigation equipment such as a hand-held wand with an injector, or ebb and flow systems.

For foliar applications, dissolve 6-12 ounces of Actinovate in 50-100 gallons of water.  Growers or gardeners can use a pump bottle, hand-held pump, backpack, or similar spray equipment to spray leaves, stems, and new shoots to wet, but not quite to run off, providing complete coverage of the entire plant.  In greenhouses and nurseries, Actinovate can be applied to the foliage via chemigation using the rate of 1-12 ounces of Actinovate per 10-200 gallons of water, depending on the desired application.  For foliar chemigation, apply the solution only through overhead boom and mist-type systems or sprinklers such as impact or micro-sprinklers.  For best results in foliar applications, use a non-ionic spreader sticker in conjunction with the Actinovate application.

Always refer to the product label for complete instructions, precautions, safety, and storage and handling before use.

Can Actinovate be part of an IPM program?

Actinovate is a great addition to any Integrated Pest Management program and can be used safely and effectively alongside beneficial fungi, such as mycorrhizal inoculant products.  Actinovate can also be used safely and effectively alongside a rotation of traditional fungicides.  Also, Actinovate does not need to be rotated, and can be used year after year, season after season, as unlike other fungicides, there are no pathogen resistance issues caused by prolonged or repeated use of biological solutions such as S. lydicus.  Actinovate is OMRI-Listed as an organic input, therefore, it is a great resource for organic growers and gardeners for organic control of fungal pathogens.  Additionally, Actinovate is Pollinator Safe, as trials have shown that exposure to Actinovate had no adverse effects on honeybees.

What Actinovate products are available for Professional Growers and Home Gardeners?
