THE DEXTRO-LAC® ADVANTAGE

Agro-K’s Copper Dextro-Lac®, a
foliar micronutrient, is derived from
copper sulfate. A series of proprietary
manufacturing processes are used to
separate the copper from the sulfate
molecule and link it to a polysaccharide
molecule creating a nutrient product
linked to a sugar base. The term Dextro-
Lac® is used to convey the process and
resulting product.

The Dextro-Lac® process creates a
foliar copper product that can quickly
penetrate plant tissue – leaves, buds,
fruit skin and bark. Nutrient uptake
happens directly through the cell
walls. Once inside the cell, the copper
polysaccharide molecule is easily
metabolized and mobilized by the
plant system.

Directions For Use
Copper Dextro-Lac is intended for foliar use. Apply 6 – 16 oz/acre (500ml – 1 liter/hectare) with sufficient water for thorough coverage. For best results, spray in early morning or late afternoon. Do not apply during the “sunlight” hours when air temperature is above 85° F/30° C. Foliar fertilization is intended to supplement standard ground fertility programs and will not by itself provide all nutrients normally required by agricultural crops. If you have any questions regarding mixing or application rates contact your Agro-K dealer before using this product.
