AZteroid FC 3.3

AZteroid FC 3.3 fungicide recently received approval from the EPA. AZteroid FC 3.3 is a new, higher-concentration formulation of the popular AZteroid FC fungicide from Vive Crop Protection.

Farmers who grow sugarbeets, potatoes, dry beans, alfalfa or corn are going to find that AZteroid FC 3.3 provides the same excellent disease control and mixability with liquid fertilizer as its predecessor. It’s simply a more concentrated formulation for added convenience.

AZteroid FC 3.3 is double the concentration of AZteroid FC, meaning that application rates will be cut in half. For both growers and retailers, AZteroid FC 3.3 will take up less storage space, require less transportation cost and fewer jugs to handle.

Both AZteroid FC and AZteroid FC 3.3 contain the Allosperse Delivery System, which uses nanotechnology to allow active ingredients to mix well with liquid fertilizer, other chemicals, micronutrients and hard water.

Mastercop

Mastercop is a higher-quality copper formulation that provides superior control of early and late blight in potatoes, with the added benefits of easier mixing, no coating of copper residues, and no soil toxicity. Unlike traditional coppers, Mastercop is 100 percent water-soluble, meaning no sludge in the tank and no clogged nozzles. It’s also more than 90 percent immediately bio-available, allowing faster activity for maximum disease control with lower rates and less phytotoxicity than other coppers. The smaller-than-average copper particles of Mastercop have more even distribution on the leaf, resulting in better spray coverage.

How is this possible? Mastercop is formulated with BioRetain technology that delivers a smaller copper particle size. This means better spray coverage with quick, uniform distribution of copper metallic ions as well an improved uptake system, including enhanced leaf adhesion, penetration, bio-availability and retention within the leaf cuticle. With broad-spectrum protection and multi-site activity, it is ideal for integrated pest management programs. Mastercop is now also OMRI-listed.
