SPINACH - SOWTHISTLE, ANNUAL, ETC. - FOR TOP GROWTH SUPPRESSION
This product is recommended for selective, post-emergence control of broadleaf weeds in barley, oats and wheat not underseeded with a legume, canola, Christmas tree plantations, fallow cropland, field corn, garden beet, grasses grown for seed, mint (spearmint and peppermint), popcorn, spinach, stone fruits, sugarbeet, sweet corn, turnip, cottonwood/poplar and eucalyptus tree plantations, rangeland and permanent grass pastures, conservation reserve program (CRP) acres, and non-cropland areas including fence rows, around farm buildings, and equipment pathways.
Precautions and Restrictions
- In California and New York, the maximum application rate for this product is 2/3 pint per acre per growing season. Do not exceed a cumulative amount of 2/3 pint [0.25 lb acid equivalent (a.e.)] of clopyralid per acre per crop year.
- Not for Sale, Use or Distribution in Nassau and Suffolk Counties in New York State.
- Do not contaminate irrigation ditches or water used for irrigation or domestic purposes.
- This product may be applied by aircraft on the following crops: spinach, canola (rapeseed), and crambe. Do not apply this product by aircraft to other labeled crops unless otherwise permitted by supplemental labeling or product bulletins.
- Do not use in greenhouses.
- Re-treatment is allowed, but do not apply more than the maximum allowable rate per crop growing season. An application to fallow cropland preceding or following an application to dryland small grains (Wheat, barley or oats) is allowed, but is not allowed preceding or following an application to irrigated small grains.
- Do not transfer livestock from treated grazing areas (or feeding of treated hay) to sensitive broadleaf crop areas without first allowing 7 days of grazing on an untreated pasture (or feeding of treated hay). If livestock are transferred within less than 7 days of grazing untreated pasture or eating untreated hay, urine and manure may contain enough clopyralid to cause injury to sensitive broadleaf plants.
- Field Bioassay Instructions: In fields previously treated with this product, plant short test rows of the intended rotational crop across the original direction of application in a manner to sample field conditions such as soil texture, soil pH, drainage, and any other variable that could affect the seed bed of the new crop. The field bioassay can be initiated at any time between harvest of the treated crop and the planting of the intended rotational crop. Observe the test crop for herbicidal activity, such as poor stand (effect on seed germination) chlorosis (yellowing), and necrosis (dead leaves or shoots), or stunting (reduced growth). If herbicidal symptoms do not occur, the test crop can be grown. If there is apparent herbicidal activity, do not plant the field to the test rotational crop; plant only a labeled crop or crop listed in the table below for which the rotational interval has clearly been met.
Apply to actively growing weeds. Extreme growing conditions such as drought or near freezing temperatures prior to, at, or following 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. Applications of this product are rainfast within 6 hours after application.
Generally, application rates at the lower end of the recommended rate range 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 rates within the 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.
To prevent misapplication, it is recommended that spot treatments be applied only with a calibrated boom or with hand sprayers according to directions provided below.
Hand-Held Sprayers: Hand held sprayers may be used for spot applications. Care should be taken to apply the spray uniformly and at a equivalent to a broadcast application. Application rates in the table are based on an area of 1,000 sq ft. Mix the amount of this product (fl oz or mL) corresponding to the desired broadcast rate in 1 or more gallons of spray. To calculate the amount of this product 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 1,000 sq ft is approximately 10.5 x 10.5 yards (strides) in size. See the table in the label for the Amount of this product per Gallon of Spray to Equal Specified Broadcast Rate
This product may be applied as a band treatment. Use the formulas to determine the appropriate rate and volume per treated acre.
Aerial Broadcast Application of This Product in Sugar Beets
(For Distribution and Use Only in the States of Colorado, Idaho, Michigan, Minnesota, Montana, Nebraska, North Dakota, Oregon, Washington, and Wyoming)
This product may be aerially applied to sugar beets in the states of Colorado, Idaho, Michigan, Minnesota, Montana, Nebraska, North Dakota, Oregon, Washington, and Wyoming. Supplemental labeling may be obtained at point of purchase, by visiting our web site at www.nufarm.com, or from your local Nufarm representative.
Refer to the product label for this product for specific weeds controlled, application rates and recommended tank mixes. When tank mixing with a companion herbicide, read and follow each manufacturer’s label for weeds controlled, applicable use directions, precautions and limitations before use.
Aerial Application: Apply the recommended rate of this product in 5 or more gallons of total spray volume per acre when weeds are at the recommend stage of growth for control.
Note: Before aerially applying this product, read and understand Spray Drift Management and Aerial Drift Reduction Advisory information.
(Not registered for use in California)
- Make 1 to 2 broadcast applications per crop per year, not to exceed a total of 1/3 pint/acre (0.125 lb ai/acre).
- Preharvest interval: Do not apply within 21 days of harvest.
Apply this product to spinach in the 2 to 5 leaf stage of crop growth. Apply this product to clover, common cocklebur, jimsonweed, and ragweed from weed emergence up to the 5 leaf stage of growth. For suppression of annual sowthistle and Canada thistle, apply this product from rosette up to bud stage.
Broadcast Application Rates: Apply to spinach in the 2 to 5 leaf stage of crop growth. Apply uniformly with ground or aerial equipment in 10 to 20 gallons of water per acre (minimum of 5 gallons per acre by air). For control of Canada thistle, apply after the majority of basal leaves have emerged but prior to bud stage and at least 21 days prior to harvest.
