Wheat image by Winks from

Curtail is an herbicide used to control broadleaf weeds in wheat and barley. Curtail is produced by Dow AgroSciences, and its active ingredients are clopyralid and 2,4-D amine. Curtail herbicide is best applied by a professional, but if you choose to use this chemical herbicide, you will need to follow all of the safety precautions. This product is hazardous to humans and animals.

Put on a long shirt and long pair of pants. Make sure you are also wearing socks and shoes. It is important to keep your skin covered as Curtail herbicide can cause irritation to the skin.

Put on protective eyewear, chemical-resistant gloves and a chemical-resistant apron. These will further protect you from injury from the Curtail herbicide.

Wait to mix and apply your Curtail herbicide for a day when the wind is less than 15 mph, and rain is not expected for six hours.

Pour your water into a backpack sprayer. Your Curtail herbicide is concentrated and must be diluted with water.

Add the Curtail herbicide. Place the lid on the backpack sprayer and give it a shake to mix the two ingredients. This will be enough herbicide to cover 1,000 square feet.

Spray over the weeds you want to kill. It helps to apply the herbicide methodically (moving from left to right, or right to left) so that you do not miss any spots.

Directions For Use Of Curtail Herbicide

Curtail is a specially formulated herbicide used by farmers and professional growers. Curtail successfully eliminates all weeds and other vegetation growing in the field, without harming the desirable wheat and barley plants. Put on long sleeves, pants, boots and gloves to cover every inch of skin. Fill the desired tank, such as a crop sprayer, with two gallons of water for each acre you want to treat. Mix the contents of the tank thoroughly. Refrain from entering the treatment area for 48 hours following the application and do not allow animals to graze on the land for seven days following treatment.


Remove and wash your clothing as soon as you have finished using Curtail herbicide. Then wash your hands.

Store leftover Curtain herbicide away from children and pets in a location that remains above 40 degrees F.
