Staple is the first broad-spectrum, low use rate, over-the-top herbicide registered for use on cotton. Staple represents a new family of chemistry with the ability to inhibit the enzyme acetolactate synthase. It is not a sulfonylurea or imidazolinone.

After entering the plant, Staple acts to inhibit cell division and growth. Rat studies indicate the herbicide has low acute oral and dermal toxicity. Cotton has demonstrated excellent tolerance to Staple when application is made early postemergence at the use rate of 1.2 ounces of product per acre. Breakdown within the environment occurs via microbial and photo-chemical pathways. Based on yield results obtained over the last six years, Staple does not adversely affect cotton yield when applied at 1.2 ounces of product per acre.

At the rate of 1.2 ounces of product per acre, Staple will control morningglory species such as entireleaf, ivyleaf, pitted, and sharppod. Staple will also control troublesome weeds such as cocklebur, velvetleaf, prickly sida, devil's claw, hairy nightshade and pigweed species. Staple will provide partial control of sicklepod and yellow nutsedge.

Staple will be packaged in water soluble packets which will result in limited container disposal and loader/mixer exposure.
