General Information


Rely 200 Herbicide is a nonselective herbicide for application as a foliar spray for the control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds. Rely 200 Herbicide will also control certain woody species. Plants that have not yet emerged at the time of application will not be controlled. THOROUGH SPRAY COVERAGE IS IMPORTANT. Visual effects and control from an application of Rely 200 Herbicide occur within 2 to 4 days after application under good growing conditions.

Avoid all contact with foliage or green tissue of desirable vegetation. Do not spray during windy conditions. This product may injure or kill growing plants that receive spray drift or if they receive applications of a spray mixture containing Rely 200 Herbicide by error or accident. If desirable vegetation is contacted, rinse the sprayed portion with water immediately to reduce potential injury.

Rely 200 Herbicide works best when weeds are actively growing. Warm temperatures, high humidity, and bright sunlight improve the performance of Rely 200 Herbicide. Weed control may be reduced when applications are made to weeds under stress due to drought or cool temperatures. Weeds under stress or in dense populations will require application at the highest specified label use rate. Stressed conditions also include prior treatments of other contact or systemic herbicides. Do not retreat these weeds with Rely 200 Herbicide until sufficient new or regrowth has occurred. Refer to the How to Apply section of the label.

Apply Rely 200 Herbicide as a directed spray to control undesirable vegetation in apple orchards, grape vineyards, and in tree nut groves for tree nuts listed below. When applied as recommended in the label, Rely 200 Herbicide controls annual and perennial weeds. Refer to the How to Apply section of the labeling for recommended rates and a list of weeds controlled. Apply as a broadcast, banded, or spot treatment application depending on the situation. Avoid direct spray or drift to desirable vegetation. Regrowth may occur due to the weed stage of growth at application, low use rate, or environmental conditions. Repeat applications of Rely 200 Herbicide may be necessary to control plants generating from underground parts or seed.

In the State of New York Only: Not For Use In Nassau and Suffolk Counties.

Limitations, Restrictions, and Exceptions


Apply Rely 200 Herbicide at the beginning of natural senescence of potato vines. Apply 29 fluid ounces of product per acre. Do not split this application or apply more than one application per harvest. Potato varieties with heavy or dense vines may require an application of another desiccation product to complete vine desiccation.

Thorough coverage of the potato vines to be desiccated is essential. Use a sufficient volume of water to obtain a thorough coverage of the potato vines.


1. Do not harvest potatoes until 9 days or more after application of Rely 200 Herbicide.

2. Do not apply to potatoes grown for seed.

3. Do not plant treated areas to wheat, barley, buckwheat, millet, oats, rye, sorghum, and triticale until 30 or more days after an application of Rely 200 Herbicide as a potato vine desiccant.

4. Do not plant treated areas to crops other than those listed above and below in this use precautions section until 120 or more days after an application of Rely 200 Herbicide as a potato vine desiccant.

5. Field corn and soybeans may be planted at any time after the application of Rely 200 Herbicide as a potato vine desiccant.

GROUND APPLICATION: Apply Rely 200 Herbicide in 20 to 100 gallons of water per acre, using 80-degree or 110-degree flat-fan nozzles. Select a spray pressure between 30 to 60 pounds per square inch (psi) measured at the nozzle that will achieve a droplet size of about 300 microns. Vary the gallons of water per acre and the spray pressure as indicated by the density of the potato vines to assure thorough spray coverage. Increase the spray volume to at least 30 gallons of water per acre when the potato vine canopy is dense or under cool and dry conditions. If Turbo TeeJet spray tips are used, a spray pressure of 60 or more pounds per square inch will be required to get thorough coverage. Do not apply when winds are gusty or when conditions will favor movement of spray particles off the desired spray target. To avoid drift and insure consistent weed control, apply Rely 200 Herbicide with the spray boom as low as possible while assuring thorough coverage of the potato vines.

AERIAL APPLICATION: Apply Rely 200 Herbicide with aerial equipment in 5 to 10 gallons of water, using the higher volume of water when potato vines are dense. Apply at a height of 10 feet or less above the potato vines and use low-drift nozzles. Adjust the nozzles to provide a uniform pattern and median droplet size of 350 to 450 microns while keeping the pressure at the nozzle at less than 40 psi. Do not apply aerially when atmospheric conditions give rise to spray drift and do not apply when wind could cause drift to surrounding vegetation.

Use for Potato Vine Dessication not permitted in California unless otherwise directed by supplemental labeling.
