Gil Gullickson The Environmental Protection Agency has approved AZterknot fungicide from Vive Crop Protection. AZterknot fungicide is the world’s first three-way fungicide combination that harnesses the benefits of biologicals, the performance of chemistry, and the ease of Allosperse, say Vive officials. Allosperse is proprietary nano-polymer technology developed by Vive Crop Protection that allows previously incompatible products to be mixed and applied in one application. Vive officials say this reduces fuel, time, and water usage. AZterknot will be available this summer through distributor and retail commercial channels in the United States. Registered in a broad range of crops for soil and foliar applications, AZterknot provides the plant health and disease control benefits of two active ingredients: Reynoutria extract and azoxystrobin, the disease-fighting active found in AZteroid FC 3.3 from Vive Crop Protection. These two modes of action combine with Vive’s patented Allosperse technology to provide unparalleled handling ease and efficiency, systemic disease control, and activation of the plant’s natural defense mechanisms, say company officials.
