however, if fog is not present, the movement of smoke produced by a ground source or an aircraft smoke generator can also identify temperature inversions. The amount of water and Glyphosate 41 you use will depend on the size of the area you intend to spray, as well as the size of your mixing container or sprayer. Unemerged plants arising from unattached underground rhizomes or root stocks of perennials will not be affected by this herbicide and will continue to grow. TYPES OF APPLICATIONS: My 10-foot spray rig lays down about 30 gallons per acre when I drive my tractor at full speed. Mixing for Hand-Held Sprayers When using application methods that result in less than complete coverage, use a 5-percent solution for annual and perennial weeds and a 5- to 10-percent solution for woody brush and trees. The following good agronomic practices are specified to reduce the spread of confirmed glyphosate-resistant biotypes: NOTE: PRODUCT PERFORMANCE MAY BE SIGNIFICANTLY REDUCED IF WATER CONTAINING SOIL SEDIMENT IS USED AS CARRIER. Weeds should be a minimum of 6 inches above the desirable vegetation. achieve control. are likely to drift. of other products for use in injection systems. Be aware that on sloping ground the herbicide solution may migrate, causing dripping on the lower end and drying of the wicks on the upper end of the wiper applicator. For example: A 3-pound-per-acre rate requires 3 pounds of herbicide for each crop acre in a broadcast application, but only 1 pound is needed to apply the herbicide in 10-inch bands on 30-inch rows. ANNUAL AND PERENNIAL CROPS (Alphabetical) Rates should be adjusted for weed height by using the standard rate for weeds < 6 inches tall, and increasing the rate by 50 and 100% for weeds between 6 and 12 inches and > 12 inches in height. The standard rate of glyphosate is 0.75 lb a.e. This may occur in dense clumps, severe from contacting desirable vegetation. In these instances, repeat treatment may be necessary. West publishing company. Make application when the per acre), based on this example, growers need to apply 50 percent less of the 4.5 lbs. action. Such equipment must be capable of preventing all crop contact with the herbicide solutions and operated without leakage of spray mists or dripping onto crop. The use of an appropriate residual herbicide will reduce the timing sensitivity of glyphosate and provide residual control until a sufficient crop canopy has formed. Attempting to target a very narrow window for weed removal also poses difficult logistical challenges, especially for large operations and those with additional in-crop field work. 84009-12 EPA Est. Growers can do little to improve glyphosate performance during extended periods of poor plant growth, such as that caused by extensive drought. *This product is not registered in California or Arizona for use in mistblowers. Limited to stock on hand. The portion of any glyphosate product with herbicidal activity is the parent acid (Figure 4).

Comparison of the critical period for weed control in wide and narrow row corn. of stock in {{wg.store.city}} No Soil Activity Tank Mixing Procedure Crop injury may occur when foliage of treated weeds comes into direct contact with leaves of the crop. Keep and wash PPE separately from other laundry. Nozzles must always point backward, parallel with the air stream and never be pointed downwards more than 45 degrees. this will create a 10 percent dilution, which is the strongest recommended for use on soil in which you intend to grow healthy plants. Wild buckwheat is another highly tolerant weed. 14.3 Annual Weeds Tank Mixtures with Atrazine for Fallow and Reduced Tillage Systems If the hood is raised, spray particles may escape and The ams is used to help the roundup do its job. per gallon = 0.375 gallons per acre or 1 quarts per acre (0.375 x 4) or 3 pints per acres (0.375 x 8) Example 7b You have calibrated a 300 gallon sprayer. This means the mixture of glyphosate is weaker as a percent of the solution. Application should Drift Reduction Additives Better results may be obtained when two applications are made in opposite directions. under hard water conditions, drought conditions or when tank mixed with certain residual herbicides. Repeat this rinsing process two more times. ;-). The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. If such symptoms are observed, provide the animal with plenty of fluids to prevent dehydration. 20:7. Check nearby stores, Not carried Operate this equipment at ground speeds no greater than 5 miles per hour. The ammount of water you use depends on three things: 1. the width of your spray cone coming from the nozzle. (For example, if the crop row width is 38 inches, the maximum width of the spray hood should be 30 inches.). Rainfastness Best control of most perennial weeds is obtained when treatment is made at late growth stages approaching maturity. Mix only the amount of this product to be used during a 1-day period, as reduced product performance may result from use of solutions held in storage. of this label. Pioneer Hi-Bred Intl, Inc.
