Powdery mildew, botrytis, downy mildew? Now those would be some scary trick-or-treaters to show up at your door this Halloween. Every grower knows that fungal spores spread aggressively and invisibly – often seeming to show up out of nowhere – and an infestation can completely throw off the growing season. For this reason, fungicides are an important tool which have earned their spot in the grower toolbox. While there are a lot of fungicides on the market, there are not many with a completely new strain of Bacillus (offering a new, higher level of performance) and a listing with the Organic Materials Review Institute, OMRI.

Mycorrhizal Applications is excited to introduce AmyloShield™ to our family of biological plant health solutions. AmyloShield™ is a sustainable, high potency biofungicide that provides consistent control and suppression of a broad spectrum of fungal diseases. This biofungicide provides significantly more disease-preventing metabolites (cyclic lipopeptides or CLPs) than the next leading biofungicide.  When using AmyloShield™, you can expect more consistent and longer-lasting disease management efficacy.


What type of grower are you? Ornamentals? Fruit and Veg? Hemp? Turf? If you answered “yes” to any of those industry segments, I recommend taking a look at AmyloShield™. Its active ingredient is a unique, proprietary strain of Bacillus amyloliquefaciens, PTA-4838. Turns out, if you combine these bacteria with advanced science, fermentation, and rigorous testing, you get a foliar spray that controls a broad range of fungal pathogens.


Top-level information you need to know about AmyloShield™:

  • Biologically derived
  • High potency
  • Ideal for foliar spray applications
  • 2-year shelf life​
  • OMRI listing
  • Made in the USA
  • Highly inclusive product label

AmyloShield™ can be applied as a foliar spray, either standalone or in combination with other registered products in a rotation or as tank mixes. As a microbial product containing live spores, AmyloShield™ produces the best results when applied preventively. You can even incorporate adjuvants such as spreader-stickers to improve coverage and enhance control. And don’t worry, you won’t need to buy any fancy equipment. You can use AmyloShield™ with all commonly used foliar spray application tools.

OMRI Listing

I have not talked much yet about the OMRI listing, but it is extremely important. Tools that help growers fight off fungal infections in the organic world often offer lesser results than their conventional counterparts, but not AmyloShield™. AmyloShield™ is a highly effective tool for growers that also happens to be OMRI listed rather than the other way around. So, it is a good choice for both organic and non-organic growers. Oh, and did I mention that it has a 0-day preharvest interval and can be applied up to and including the day of harvest? Follow label instructions and be confident that you are making a good choice for the environment, your staff, and yourself.
