COTTONWOOD/POPLAR AND EUCALYPTUS TREE PLANTATIONS
Solix 3 herbicide is recommended for selective, postemergence control of broadleaf weeds and select woody brush species in asparagus, 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, sugar beet, 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, equipment pathways, industrial manufacturing and storage sites, forest sites, and rights-of-way (such as along roadsides, electrical lines and railroads). Use on these sites may include application to grazed areas as well as establishment and maintenance of wildlife openings, wild parkland and wildlife management areas, and forest spot application adjacent to these sites.
PRECAUTIONS AND RESTRICTIONS
- Use directions in Makhteshim Agan of North America, Inc. supplemental labeling may supersede directions or limitations in the labeling.
- In California, the maximum application rate for Solix 3 is 2/3 pint per acre per growing season. Do not exceed a cumulative amount of 2/3 pint (0.25 lb. active ingredient (a.i.)) of clopyralid per acre per crop year.
- Do not contaminate irrigation ditches or water used for irrigation or domestic purposes.
- Solix 3 may be applied by aircraft on the following crops: spinach, canola (rapeseed), crambe and sugar beets. Do not apply Solix 3 by aircraft to other crops unless otherwise permitted by Makhteshim Agan of North America, Inc. supplemental labeling or product bulletins.
- Do not use in greenhouses.
- Chemigation: Do not apply this product through any type of irrigation system.
- 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. The test area should 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 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 above for which the rotational interval has clearly been met.
- In Arizona: The state of Arizona has not approved Solix 3 for use on plants grown for agricultural/commercial production such as on designated grazing areas.
- Use of this product in Oregon is limited to the sites stated on the label which are agricultural, forest and right-of-way.
- In Florida, Solix 3 can be used only in the following counties: Bay, Bradford, Calhoun, Escambia, Franklin, Gadsden, Gulf, Hamilton, Jackson, Jefferson, Lafayette, Leon, Liberty, Madison, Okaloosa, Santa Rosa, Suwanee, Taylor, Wakulla, Walton and Washington.
- Rotation to Broadleaf Crops: Do not plant broadleaf crops in treated areas until an adequately sensitive bioassay shows that no detectable clopyralid is present in the soil.
- Grazing/Haying: There are no restrictions on grazing or hay harvest following application of Solix 3 at labeled rates.
- Some desirable broadleaf plants (forbs) are susceptible to Solix 3. Do not spray pastures containing desirable forbs, especially legumes, unless injury can be tolerated. However, the stand and growth of established perennial grasses is usually improved after treatment, especially if rainfall is adequate for active plant growth and grazing is deferred.
- Grasses are tolerant to Solix 3, but new grass seedlings may be injured to varying degrees until well established as evidenced by development of secondary roots and tillering (multiple stems).
- Do not use hay or straw from treated areas for composting or mulching on susceptible broadleaf crops.
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 treatment with Solix 3 will be 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 large 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.
Use sufficient spray volume to provide thorough coverage and a 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. As vegetative canopy and weed density increase, spray volume should be increased 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 Non-Target Plants.
To prevent misapplication, spot treatments should be applied with a calibrated boom or with hand sprayers according to directions provided in the label.
Hand-held sprayers may be used for spot applications of Solix 3 if care is taken to apply the spray uniformly and at a rate equivalent to a broadcast application. Application rates in the table are based on an area of 1000 sq. ft. Mix the amount of Solix 3 (fl. oz. or mL) corresponding to the desired broadcast rate in one or more gallons of spray. To calculate the amount of Solix 3 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 3500 sq. ft., multiply the table value by 3.5 (calc. 3500/1000 = 3.5). An area of 1000 sq. ft. is approximately 10.5 X 10.5 yards (strides) in size.
Refer in the label regarding tank mix information.
Broadleaf Weeds Controlled: See Guidelines for Control of Specific Weeds for additional information on application timing and application rates.
Buffalobur, Knapweed Russian, Ladysthumb, Sowthistle Perennial, Smartweed Green: These weeds may only be suppressed. Suppression is a visual reduction in weed competition (reduced population or vigor) as compared to untreated areas. The degree and duration of weed control will vary with weed size and density, application rate and coverage, and growing conditions before, during, and after the time of treatment. For perennial weeds such as Russian knapweed and perennial sowthistle, Solix 3 will control the top growth and inhibit regrowth during the season of application (season-long control). At higher use rates shown on the label, Solix 3 may cause a reduction in shoot regrowth in the season following application; however, plant response may be inconsistent due to inherent variability in shoot regrowth from perennial root systems.
Wormwood Biennial: Not approved for use in California.
Mesquite: Not For Use in California
COTTONWOOD/POPLAR AND EUCALYPTUS TREE PLANTATIONS
Solix 3 may be used for postemergence control of labeled broadleaf weeds in new and established plantings of cottonwood/ poplar and eucalyptus tree plantations. Apply as a broadcast foliar spray over trees or as a banded or directed spray. Apply in 10 or more gallons per acre total spray volume using ground equipment only. Multiple applications may be made as long as the total rate per annual use season does not exceed 1 1/3 pints/acre. Apply to new plantings only after they are well established as indicated by several inches of new healthy growth.
Spot applications using hand-held equipment are also allowed, but contact with tree foliage should be avoided or limited to lower branches. Apply to weeds on a spray-to-wet basis with spray coverage uniform and complete. Do not spray to the point of runoff. Prepare a spray solution by adding 1/4 fl. oz. Solix 3 per gallon of water. When applied at 1 gallon of spray per 1000 sq. ft., this spray concentration is equivalent to a broadcast rate of 2/3 pint per acre.
Specific Use Precautions:
- Do not tank mix Solix 3 with other herbicides labeled for this use unless applicator can insure that spray avoids all contact with tree foliage.
- Solix 3 will not control certain broadleaf weeds including mustards, henbit, chickweed, kochia, lambsquarters, pigweed, Russian thistle and bindweed.
