NON-CROPLAND - ANNUAL AND PERENNIAL BROADLEAF WEEDS AND WOODY VINE CONTROL - BROADCAST FOLIAGE TREATMENT
Use of this product in certain portions of California, Oregon and Washington is subject to the January 22, 2004 Order for Injunctive Relief in Washington Toxics Coalition et al v. EPA, C01-0132C (W.D.W.A.). For further information, please refer to http://www.epa.gov/espp.
Sekor P+D is a water soluble liquid product containing picloram and 2,4-D. Use Sekor P+D in permanent grass pastures and rangeland to selectively control many annual, biennial, and perennial broadleaf weeds and woody species listed on the label. Sekor P+D may also be used for control of unwanted annual and perennial broadleaf weeds and woody plants and vines on forest planting sites and non-crop areas including industrial, manufacturing, and storage sites; rights-of-way, such as railroads, electric power lines, communication lines, pipelines, highways; and wildlife openings in forest and non-crop areas.
Herbicidal effects of Sekor P+D occur primarily from uptake by plant foliage and translocation throughout the plant; however, secondary herbicidal activity may occur from soil uptake of picloram. Broadleaf plants can be killed or damaged by very small amounts of Sekor P+D. To prevent damage to crops and other desirable plants, carefully follow all directions and precautions.
PRECAUTIONS AND RESTRICTIONS
Observe any special use and application restrictions and limitations, including method of application and permissible areas of use as required by state or local regulations. When used in tank mix combination with other products, follow all applicable use directions, precautions, restrictions, and limitations on the labels of each product used.
Application Rate Ranges: Use higher rates in areas with dense weed populations or for longer residual weed control. For best results, the lower rate should be used only when environmental conditions are favorable for plant growth and when the plants are in the recommended growth stage. Compared to results obtained with the higher rate, a lower rate may be slower to show activity, provide a lower level of control, and may require re-treatment.
Grazing Restrictions: There are no grazing restrictions for non-lactating dairy animals or other livestock including horses, sheep, goats, and other animals in the treatment area. Do not allow lactating dairy animals to graze treated areas within 7 days after application. Do not harvest grass cut for hay from treated areas for 30 days after application. Meat animals must be withdrawn from treated forage at least 3 days before slaughter.
Do not rotate to crops intended for food or feed use on areas treated with this product, other than range or pasture grasses, rye, forage sorghum, sudangrass, wheat, barley or oats not underseeded with a legume.
Do not move treated soil or use treated soil for growing other plants until soil residues of picloram are no longer detectable as indicated by an adequately sensitive bioassay or chemical test.
Do not apply Sekor P+D in residential areas or near ornamental trees and shrubs. Untreated trees can be affected by root uptake of the herbicide through movement into the top soil or by excretion of the product from the roots of nearby treated trees. Do not apply Sekor P+D within the area occupied by roots of desirable trees, unless such injury can be tolerated.
Established grasses are tolerant to this product, but newly seeded grasses may be injured until well established as indicated by tillering, development of a secondary root system and vigorous growth (refer to the Planting Grasses Section of the label).
Sekor P+D may suppress certain established grasses such as smooth bromegrass, Willman’s lovegrass, and buffalograss. However, subsequent grass growth should be improved by release from weed competition. Smooth bromegrass and Willman’s lovegrass grown for seed may be sensitive to this product if applied under adverse growing conditions (moisture stress).
If injury to existing forage legumes cannot be tolerated, do not spray pastures. Sekor P+D may injure or kill legume plants. Forage legumes may be less sensitive to the herbicide after the seed has set and plant growth is mature. Seeding of legumes may not be successful if made within one year of application.
Do not mix with dry fertilizer.
Do not transfer livestock from treated grazing areas to broadleaf crop areas without first allowing 7 days of grazing on untreated grass pasture. Otherwise, urine may contain enough picloram to cause injury to sensitive broadleaf plants.
Do not use manure from animals grazing treated areas on land used for growing broadleaf crops, ornamentals, orchards, or other susceptible, desirable plants. Manure may contain enough picloram to cause injury to susceptible plants.
Do not use hay or grass from treated areas or manure from animals being fed treated forage or hay for composting or mulching of desirable, susceptible broadleaf plants.
Do not contaminate water intended for irrigation or domestic purposes. Do not treat or allow spray drift or runoff to fall onto banks or bottoms of irrigation ditches, either dry or containing water, or other channels that carry water that may be used for irrigation or domestic purposes. Do not apply to snow or frozen ground.
Do not apply or permit Sekor P+D or sprays containing Sekor P+D to contact crops or other desirable broadleaf plants, including but not limited to alfalfa, beans, cotton, grapes, melons, peas, potatoes, safflower, soybeans, sugar beets, sunflower, tobacco, tomatoes, and other vegetable crops, flowers, fruit plants, ornamentals, and shade trees.
Do not use Sekor P+D on sub-irrigated land.
Avoid injury to newly planted conifers. Conifer plantings vary. Pines planted sooner than 6 months after treatment with Sekor P+D may be injured in the South or west of the Cascade Mountains. Other conifers west of the Cascade Mountains may be injured if planted sooner than 8 to 9 months after treatment. For all conifers, the waiting period between treatment and planting should be 11 to 12 months in the area between the Cascade and Rocky Mountains and 8 to 9 months in the Lake States and Northeastern U.S.
For Mixing Application Instruction information, please refer to the label.
SPECIFIC USE DIRECTIONS NON-CROPLAND
Broadcast Ground or Aerial Foliage Treatment
For ground applications, make applications of Sekor P+D in 15 or more gallons of total spray mixture per acre.
For aerial applications, use 5 to 20 gallons of spray mixture per acre. Use higher spray volumes where plants are tall, where the vegetation to be treated is dense, or where difficult to control species are present.
Broadleaf Annual and Perennial Weed and Woody Vine Control: Apply Sekor P+D at rates of 2 to 3.7 quarts per acre in a water spray mixture. Apply to problem weeds and vines any time after growth begins in the spring and late in summer or fall.
Apply 2 to 3 quarts of Sekor P+D per acre in water spray for season control of vigorously growing stands of field bindweed, Canada thistle, or mixtures of these with susceptible annual weeds such as ragweed, dandelion, plantain, clovers, and dock.
Use up to 3.7 quarts of Sekor P+D per acre in arid areas and for control of more resistant perennial weeds.
Use up to 3.7 quarts per acre to control species such as Canada thistle, field bindweed, and milkweed. The higher rates should be used under drought stress conditions and for the more resistant species such as bouncingbet, leafy spurge, toadflax, and woody vines. The spectrum of activity can be improved by tank mixing 2 to 3.7 quarts of Sekor P+D with 1/3 to 1 gallon of Triclopyr 3A (or Alligare Triclopyr 3) or 1 to 3 quarts of Triclopyr 4E (Alligare Triclopyr 4) per acre.
