Foliar and Soil Nutrient

Optimize flowering and fruit set

Containing patented Verdesian technologies discovered by Los Alamos National Laboratories and the University of California at Riverside, Primacy ALPHA® works inside the plant to stimulate the efficient assimilation and utilization of nutrients. Primacy ALPHA also functions as a reproductive growth catalyst that collectively stimulates, intensifies and optimizes plant metabolism; encourages rapid plant nutrient uptake; promotes plant growth and enhances consistent crop quality and yield potential.

Versatile in both soil and foliar applications and compatible with commonly used fertilizers and pesticides, Primacy ALPHA is a critical part of your fertility program, with proven performance on a wide range of crops including cereals, alfalfa, tree nuts, grapes, citrus, strawberries, brassica crops (broccoli, cauliflower) and fruiting vegetables (tomatoes, peppers). Primacy ALPHA is a phosphite-free product providing critical secondary nutrients and micronutrients that facilitate rapid plant growth, increased productivity and stress mitigation.
