Vinegar Weed Control Herbicide
20% Acetic Acid (Vinagreen)
Horticultural 20% Vinegar Biopesticide - for Non-Selective Control of Herbaceous Broadleaf Weeds and Weed Grasses which Surround Food crops, Non-food crops and Non-production Agricultural, Farmstead, Right-of-Way, and Institutional Land Sites.
Vinegar Weed Control Herbicide is vinegar at 20% acetic acid, manufactured the same way as food grade vinegar. Vinegar Weed Control is the result of the acetous fermentation of dilute ethyl alcohol from agricultural origin.
The alcohol is converted to acetic acid by the microorganism Acetobacter aceti in vinegar generators or acetators. The product is prepared in accordance with the best commercial practice. It is free of clarifiers, preservatives or other impurities.
A quick-acting, non-selective contact herbicide containing an organic acid for which the residues degrade promptly in the soil. Foliar contact results in rapid desiccation and control of annual weeds and grasses, and top growth reduction of herbaceous perennial weeds and grasses. For control of established perennial weeds, retreatment may be necessary. May be applied up to and including the day of harvest.

Timing of Applications
Best results are achieved from applications to actively growing young weeds. Weeds that are mature, dormant, or hardened due to moisture stress are more tolerant of herbicide treatments. For best results spray in full sunshine at temperatures above 65°F. Only contacted vegetation will be affected.
EARLY SEASON ANNUAL WEED CONTROL
Apply this product when weeds are small (3 to 5 leaf stage) and actively growing. Spray this product on unwanted weeds (vegetation) to the point of wetness. For best results spray in full sunshine at temperatures above 65 degrees Fahrenheit. Since dilution of this product will reduce effectiveness, do not dilute. Avoid spraying landscape plants, ornamentals and other desirable foliage as this product causes severe injury to desirable plants.
SPOT TREATMENT APPLICATION
Direct spray with a single nozzle or a hand-gun applicator to thoroughly wet undesirable weed foliage. Re-treatment of perennial weed growth may be required for control.
BROADCAST SPRAY APPLICATIONS
For broadcast spray application to control weeds. Application types include pre-plant (prior to crop establishment), preharvest desiccation (to kill crop foliage prior to harvesting the crop) postharvest crop desiccation (remaining crop residues after crop has been harvested). Use 15 to 30 gallons of this product per acre. Thorough coverage is necessary to achieve desirable control. For dense weed populations and/or heavy foliage, use the higher spray volume to ensure adequate coverage. Apply with flat fan nozzles and at sufficient pressure to achieve required coverage, but do not exceed a pressure 35 PSI. When applying this product in a broadcast application within a growing crop, utilize a hooded sprayer, shielded, or other spray equipment that prevents the movement of spray away from the target. For pre-plant burndown of young vegetation, use of wide angle nozzles (110 degrees or wider) spaced close together enable the boom to be positioned lower and closer to the spray target, reducing the potential for drift.
POST-EMERGE DIRECTED SPRAY
(Row middles, shielded sprayer or hooded sprayer): For spray application to control weeds, apply 15 to 30 gallons of this product per acre. Thorough coverage is necessary to achieve desirable control. For dense and/or heavy weed populations, use the higher spray volume to ensure adequate coverage. Apply with flat fan nozzles and at the lowest pressure needed to achieve required coverage, but do not exceed 35 PSI. If treating along the side of crop plants, shielded or hooded sprayers must be used to avoid crop injury.
CONTROL OF LARGER ANNUALS AND BURNDOWN OF PERENNIAL WEED GROWTH
Larger annual weeds and perennials are more difficult to control and may require retreatment. Treat initially as recommended above and repeat if new growth of leaves appears. Thorough coverage of all weed foliage is necessary to achieve desirable control. To reduce the amount of product required to control well-established weed stands, mow to a height of 4-6 inches and remove cut vegetation before applying this product.
USE OF ADJUVANTS RECOMMENDED
For both non-organic and certified organic operations, the addition of a high quality adjuvant can substantially enhance the performance of the vinegar herbicide through improved leaf surface coverage and adherence. Certified organic operations will need to use an adjuvant approved for organic use.
