Curtail Herbicide (Cody Clopyralid)

Free Shipping on All Orders

Curtail Herbicide with clopyralid and 24d from Alligare is a selective herbicide used as a horsetail weed killer but it also controls many other invasive weeds in pastures. It has an alternative name of Cody Broadleaf Herbicide. Curtail Herbicide is typically sold only to agricultural applicators but it is the best weed killer money can buy.

Target Pests

Cody Herbicide is primarily used as a horsetail weed killer but can also be used for the control of annual biennial and perennial broadleaf weeds like buffalobur burdock clover cocklebur dandelion dock fixweed groundsel horse tail weed jimsonweed knapweed kochia lambsquarters locoweed nightshade pennycress pigweed plantain ragweed sheperdspurse smartweed sowthistle sunflower thistle and many other listed weeds.

For Use In

Cody Herbicide is for use in wheat and barley not underseeded with a legume fallow cropland grasses grown fro seed rangelands permanent grass pastures conservation reserve program acres and non-croplands.


GENERAL INFORMATION Alligare Cody Herbicide is recommended for selective, postemergence control of broadleaf weeds in wheat and barley not underseeded with a legume, fallow cropland (including summer fallow, post-harvest, and set-aside acres) rangeland and permanent grass pastures, land in the Conservation Reserve Program (CRP) and non-cropland.

Application Timing: Apply to actively growing weeds. Extreme growing conditions such as drought or near freezing temperatures prior to, at and following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Only weeds that have emerged at the time of application will be affected. If foliage is wet at the time of application, control may be decreased. The Alligare Cody Herbicide treatment will be rainfast within 6 hours after application.

Application Rates: Generally, lower labeled application rates will be satisfactory for young, succulent growth of susceptible weed species. For less sensitive species, perennials, and under conditions where control is more difficult (plant stress conditions such as drought or extreme temperatures, dense weed stands and/or larger weeds), the higher rate range will be needed. Weeds in fallow land or other areas where competition from crops is not present will generally require higher rates for control or suppression. Use of Surfactants: Addition of wetting and/or penetration agents is not usually necessary when using Alligare Cody Herbicide; however, if a surfactant will be added to the spray solution, use a non-ionic surfactant suitable for use in growing crops of at least 80% active ingredient and do not exceed 4 pints per 100 gallons of spray solution (0.5% v/v). Use of a surfactant in the spray mixture may increase weed control effectiveness but may reduce crop safety, particularly under conditions of plant stress.

Spray Coverage: Use sufficient spray volume to provide thorough coverage and uniform spray pattern. Do not broadcast apply in less than 2 gallons of total spray volume per acre. For best results and to minimize spray drift, apply in a spray volume of 10 or more gallons per acre. In general, spray volume must be increased as crop canopy, height and weed density increase in order to obtain equivalent weed control. Use only nozzle types and spray equipment designed for herbicide application. To reduce spray drift, follow precautions under “Avoiding Injury to Nontarget Plants” Hand-Held Sprayers: Hand-held sprayers may be used for spot applications of Alligare Cody Herbicide if care is taken to apply the spray uniformly and at a rate equivalent broadcast application. Application rates in the table are based on an area of 1,000 sq ft. Mix the amount of Alligare Cody Herbicide (fl oz or ml) corresponding to the desired broadcast rate in one or more gallons of spray. To calculate the amount of Alligare Cody Herbicide required for larger areas, multiply the table value (fl oz or ml) by the area to be treated in “thousands” of square feet, e.g., if the area to be treated is 3,500 sq ft, multiply the table value by 3.5 (calc. 3,500 ÷ 1,000 = 3.5). An area of 1000 sq ft is approximately 10.5 X 10.5 yards (strides) in size.

Coverage Area

Each 2.5 gallon container of Cody Herbicide will cover an estimated 5 acres if used at the maximum amount per acre per year. Each gallon of Cody as a broadcast or spot treatment should cover approximately 1,000 square feet.

Time to Kill

Cody Herbicide will eliminate the unwanted vegetation in just 21 to 28 days.

Mix Rate

MIXING INSTRUCTIONS 1. Add 3/4 of the required spray volume to the spray tank and start agitation. 2. Add the required amount of Alligare Cody Herbicide. 3. Add any surfactants, adjuvants or drift control agents according to manufacturer’s label. 4. Agitate during final filling of the spray tank and maintain sufficient agitation during application to ensure uniformity of the spray mixture.
