New biofungicide available to leafy greens growers

Leafy greens growers now have a new biofungicide to protect against fungi, bacteria and soil-borne diseases.

Aviv is the first clear liquid non-staining bacillus formulation. It is a new approach to biofungicides, using ruggedized spores that grow and colonize on the foliage to build a protective physical barrier — offering active disease control that lasts longer. Aviv’s formulation includes environmental and photo degradation protection to ensure consistent performance. Field research has confirmed that Aviv’s spectrum of activity is wider than other bacillus choices. Therefore, growers don’t have to use different bacillus for botrytis and powdery mildew.

“Aviv uses a patented manufacturing process to optimize the bioavailability of its active ingredient, a newly discovered strain of Bacillus subtilis IAB/BS03 with broad-spectrum disease control,” said Sym-Agro President Peter Bierma. “This process helps AVIV solubilize completely in the spray tank, eliminating the risk of clogged application equipment and leaving no visual deposit on treated crops.”

In addition, the increased bioavailability of Aviv’s active ingredient means low use rates, about 60 percent lower than other bacillus-based fungicides . It also costs less than competing bacillus products. For conventional growers, a 10-ounce use rate can economically be added to increase disease defense and provide solid resistance management.

Studies show higher efficacies than standard bacillus products. Aviv can be tank mixed with a wide variety of other crop protection products, including bactericides such as copper.

Aviv recently was awarded the Agro innovative formulation of the year for the new approach to bacillus fungicide.

The product is colorless, odorless and offers higher stability than other bacillus products. Aviv was recently registered in California and is available to growers.
