SUPPRESS® HERBICIDE EC

1 of 1 products in this brand
SUPPRESS® Herbicide EC is a non-selective, post-emergent, foliar herbicide for use in and around all food and non-food crop areas, as well as non-agricultural and industrial sites. SUPPRESS® works best on newly emerged weeds. For more mature weeds, use the higher application rates (6% to 9%) with up to 100 gallons of water per acre. For maximum weed control, apply SUPPRESS® directly on the targeted weeds. Product must be sprayed in a manner to avoid drift damage to the crop, such as applying with hooded spray equipment. Use enough water to thoroughly cover the weeds.

Features & Benefits

Product Highlights

Developed by Westbridge Agricultural Products, SUPPRESS® Herbicide EC is a highly effective EPA registered tool for organic growers. This proprietary product is registered as a non-selective, post-emergent, foliar herbicide for use in and around all food and non-food crop areas, as well as non-agricultural and industrial sites. The formulation is an emulsifiable concentrate that has been approved by OMRI and WSDA for use in certified organic food production. Weed management is an ever-present problem in agriculture. Yields are reduced as weeds compete for space and resources that crops depend on, and weeds act as hosts for insect pests and plant diseases which can move into cultivated crops. Weed control is always a huge challenge for organic growers and there are few effective and economical options available for use on organic food crops. SUPPRESS® provides growers with a valuable tool to help meet their production goals.

Applications & Uses

Efficacy

In years of university and commercial trials, SUPPRESS® has consistently shown excellent results in controlling various weeds. Plant responses can usually be seen shortly after application

Mode Of Action

The active ingredients in SUPPRESS® are naturally-occurring fatty acids which disrupt the plant’s waxy cuticle and cell walls, causing weeds to dehydrate and die. SUPPRESS® is not volatile; therefore, vapor damage will not occur to non-target plantings.

Application Rates

Use the lower use rate range for young, succulent and actively growing weeds and the higher rate for weeds greater than six inches in height. Use the highest rate for perennial weeds when the plants have “hardened.”

  • Use a 3% solution for control of annual weeds.
  • Use a 6% solution for burndown of perennial herbaceous plants and weeds.
  • Use a 9% solution when maximum vegetative burndown, edging, or foliar trimming is desired.

Repeat applications as required to maintain desired level of weed control and to control plants emerging from seed and underground parts.
