DO NOT MIX, STORE OR APPLY THIS PRODUCT OR SPRAY SOLUTIONS OF THIS PRODUCT IN GALVANIZED STEEL OR UNLINED STEEL (EXCEPT STAINLESS STEEL) CONTAINERS OR SPRAY TANKS. concentration should be used for product rate calculation. Idealized view of herbicide diffusion into a leaf. Ok you know your spraying 1 acre. Avoid operating this equipment on rough or sloping terrain where the spray hoods might be raised up off the ground surface. 41 glyphosate application rate per acre. Keep people and pets off treated areas until spray solution has dried. seconds. PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated, such as plants, soil, or water, is: coveralls, limited. Do not reuse this container for any other purpose. In the early 1970s when glyphosate was first discovered, Monsanto marketers were perplexed. Effect of post-emerge glyphosate application timing on weed control and grain yield in glyphosate-resistant corn: results of a 2-yr multistate study. 2007) and corn (Tharp et al. Tank Mixing Procedure Species such as morningglory (spp.) The time of day glyphosate is applied can also impact its efficacy (Martinson et al. Therefore, any environmental condition speeding the drying of spray droplets on a leaf surface will reduce absorption. Use the You can figure out how to calibrate your sprayer in a bunch of different ways to measure how many gallons per acre it's spraying -- look it up on the internet. As density of weeds increases, spray volume should be increased For specific details on control of these target pest and use rates check the label provided. The widespread use of glyphosate is due in part to its very broad weed spectrum and high efficacy. Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. 8. Glyphosate is one of the most widely used herbicides in the North America. And spread lime and fertilizer as needed and yes till it in. Through the screen, fill the tank one-half full with water and start gentle agitation. Droplet evaporation is most severe when conditions are both hot and dry. Bradley, K. W., N. H. Monnig, T. R. Legleiter, and J. D. Wait. For any crop not listed in this label, applications must be made at least 30 days prior to planting. J. Do not Nozzle orientation: Orienting nozzles so that the spray is released backwards, parallel to the airstream, will produce larger droplets than other orientations. per acre; determine the product rate by using 0.75 as the numerator and the parent acid concentration as the denominator to determine gallons of product per acre (0.75/parent acid concentration = gallons/acre * 128 = oz/acre). Hazards to Humans and Domestic Animals With increased weed density and diversity, limited early-season nitrogen, and inadequate rainfall, the critical period can be expected to lengthen. The combined total of all treatments must not exceed 10.6 quarts of this product per acre per year. 2. For any requirements specific Heap, I. Higher pressure reduces droplet size and does not improve canopy penetration. Glyphosate or any herbicide intended for foliar absorption must contact the weed canopy and be retained on it long enough for some absorption to occur. Operate this equipment at ground speeds no greater than 5 miles per hour. 53883-266. pasture grasses, forage legumes, rangelands, The pubescence on the surface of many weed species can physically limit contact between a leaf surface and a water droplet containing herbicide. Apply this product during fallow intervals preceding planting, prior to planting or transplanting, at-planting, or preemergence to annual and perennial crops listed in this label, except where specifically Therefore, adding AMS to the spray solution after adding the glyphosate will do little to improve the herbicide's activity. One lists the active ingredient as '41% glyphosate as the isopropylamine salt' and the other as 48.7% glyphosate as the potassium salt'. Glyphosate products also vary in their parent acid concentrations. Total in-crop applications from emergence through the 48 inch stage 3.0 quarts per acre Maximum pre-harvest application rate after maximum kernel fill is 1.0 quart per acre complete and the crop is physiologically mature (black layer formation) until 7 days before harvest Combined total per year for all applications 8.0 quarts per acre. This to control most perennial weeds. 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. PROLONGED EXPOSURE OF THIS PRODUCT Because of its effectiveness on large weeds, many producers may overlook application timing and interactions with cropping management as critical decisions for glyphosate. Check nearby stores, Not carried For spot spraying, most glyphosate (Roundup) labels will tell you to use about 1.5-2% solution of the concentrate (about 50% glyphosate). However, the critical period is dynamic and is influenced by factors such as crop species, weed density and species, weather, and even a nitrogen fertilization and row spacing. in this product's labeling. Herbicide-tolerant soybean has exceeded 90% of U.S. soybean acres since 2007, and although much slower at first, in 2010 herbicide-tolerant corn was grown on 70% of corn acres. Table 1. Control is considered to be fair to poor at 0.75 lb a.e. This item is not available for This product mixes readily with water. 2007. Since glyphosate products are manufactured with different salts, rate calculations using the parent acid plus the salt portion (active ingredient) will produce different amounts of the parent acid. To determine whether your county or Non-refillable container greater than 5 gallons: Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow begins to Weed species having some tolerance to glyphosate. Pressure rinse as follows (all sizes): Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Reduced susceptibility to glyphosate or tolerance is inherent in a weed species or population and does not indicate a genetic change as resistance does. product by thoroughly flushing with water. Additionally, glyphosate-resistant crops allow the in-crop use of the herbicide without the risk of crop injury. Wastes resulting from the use of this product that cannot be used or chemically re-processed should be disposed of in a landfill approved for pesticide disposal or in accordance Some crop injury may occur if dicamba or Tordon 22K is applied within 45 days of planting. Observe all labeled safeguards until container is cleaned, reconditioned, or destroyed. Physical resources such as water, mineral nutrients, and light being competed for by crops and weeds are often in sufficient supply for dense seedling populations of both. Maximum size refers to the maximum plant height, length of runners for vines, or circumference of rosette plants in inches. Do not apply this product when crop leaves are growing in direct contact with weeds to be treated. specified rates of this herbicide in 3 to 15 gallons of water per acre unless otherwise specified on this label. Weed Technol. 2003; Norsworthy and Oliveira 2004; Dalley et al. forage legumes and rangelands. Selective Equipment Effects are visible on most annual weeds within 2 to 4 days, but on most perennial weeds effects may not be visible for 7 days or A foliar application should be "rain fast" once droplets have dried on the leaf surface. Example 7a A rate of 3 lbs/acre of the active ingredient (a.i.) AVOID APPLYING AT EXCESSIVE SPEED OR PRESSURE. outside the target area in order to avoid unwanted crop destruction. are not acceptable, return at once unopened. Refer to the individual use area A single, low pressure low-drift flat-fan nozzle with an 80 to 95 degree spray angle positioned at the top Spray that, wait for the glyphosate to dry (same day) and spread the Clover and pack it in. Wind For use only in Colorado, Kansas, Nebraska, Oklahoma, Oregon, South Dakota, and Washington. This item will be shipped to you. Avoid leakage or dripping onto desirable vegetation. Dry, spray-grade AMS should be added at a rate of 8.5 pounds to 17 pounds of AMS per 100 gallons of spray solution. The active ingredient in this product inhibits an enzyme found only in plants and microorganisms that is essential to the formation of specific amino acids. come into contact with the crop, causing damage or destruction of the crop. 2006. 3. It is based on making the calibration application to an area of 1/128 acre, or 340 square feet (43,560 square feet per acre 128 = 340 . Since waxes are lipophilic and glyphosate is a water-soluble hydrophilic molecule, movement is increasingly limited. Drift reduction additives may be used with all equipment types, except wiper applicators, sponge bars and Controlled Droplet Applicator (CDA) equipment. Nozzles must always point backward, parallel with the air stream and never be pointed downwards more than 45 degrees. tillage or crop rotation) where appropriate.

Change Your Store, Questions About a Recent Online Order? 2006). Weed Control Guide for Ohio and Indiana, 2004. Table 2. GENERAL PRECAUTIONS, RESTRICTIONS: Temperature, soil moisture, and solar radiation that optimize plant growth facilitate absorption and translocation of glyphosate. Best results are obtained when soil moisture is adequate for active weed growth. Non-selective, broad-spectrum weed control for many agricultural systems and farmsteads. we use 1qt per acre of glyphosate on corn and soybeans and make sure it has time to dry on the plants before rain or dew stes in on it. Screen size in nozzle or line strainers should be no finer than 50 mesh. Enlist Duo is a premix of 2,4-D choline and glyphosate with a maximum application rate of 4.75 pints per acre. Use of drift reduction additives can affect spray coverage, which can reduce product 41% Concentrate with Surfactant Mixing Rates: Use 1 -1/3 oz. agitation. Gower, S. A., M. M. Loux, J. Cardina, S.

Sprauge, M. Vangessel, and B. G. Young. Always, always, always read the label on any chemicals that you use. Repeat this rinsing process two more times. For best results, use a 2-percent solution on harder-to-control perennials, such as Bermudagrass, dock, field bindweed, hemp dogbane, milkweed and Canada thistle. from contacting desirable vegetation. These procedures will reduce the potential for crop injury: Spray hoods must be operated on the ground or skimming across the ground surface. a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Boom length: For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width. Crop Management doi: 10.1094/CM- 2005-0718-02-RS. Their presence can be indicated by ground fog; wiping surfaces clean. and wild buckwheat are difficult to control with glyphosate. Take care not to spray or allow spray to drift Leaf surfaces also consist of an uneven epicuticular wax that serves to further reduce contact between water droplets and the leaf surface (Figure 1). For maximum field performance glyphosate applications should be made with ammonium sulfate and an NIS (Hartzler et al. unless otherwise noted in this product label, or in separate supplemental labeling. Use low-drift nozzles that provide uniform coverage within the treated area. Date: 27-Apr-12. If dry ammonium sulfate is being used, ensure that it is may also contact SafetyCall International (866) 897-8050 for emergency medical treatment information. Using tillage or preemerge herbicides should reduce weed density prior to a glyphosate application and help maintain the value of herbicide-tolerant crops. The addition of 1 to 2 percent dry ammonium sulfate by weight or 8.5 to 17 pounds per 100 gallons of water may increase the performance of this product on annual and perennial weeds, particularly stock, see options for availability, {{storeQuantity}} in stock in {{wg.store.city}}, Limited stock in {{wg.store.city}} 2003) by reducing the competitiveness of weeds (Hock et al. Harmful if inhaled. Mix spray solutions of this product as follows: Begin filling the mixing tank or spray tank with clean water. At these rates of application, the total volume of glyphosate applied in 2014 was sufficient to treat between 22 and 30 % of globally cultivated cropland. 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. residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal Hand-Held or Backpack Equipment per gallon, while Gly-4 contains 3 lb. Non-selective, broad-spectrum weed control for many agricultural systems and farmsteads. The sulfate anion in ammonium sulfate binds with the salts in hard water and precipitates them out of solution, reducing the antagonistic effect. Weeds not contacted by the herbicide solution will not be affected. FarmWorks 41% Glyphosate Grass & Weed Killer is not manufactured . 2006.
