. When photosynthetic rates are high photoassimilate produced in leaf epidermal cells is rapidly loaded into the phloem, other organic molecules like glyphosate are similarly loaded, and both are quickly translocated to sink organs (Figure 2).

Hold container For specific details on control of these target pest and use rates check the label provided. and timing, refer to the "ANNUAL WEEDSHAND-HELD OR BACKPACK EQUIPMENT" section of this product label. Producers may have to choose between yield losses due to early-season weed competition and herbicide efficacy when basing weed control on a single glyphosate application. annual weeds, perennial weeds, trees, vines, Equipment must be designed, maintained and operated to prevent the herbicide solution when wind is blowing away from the sensitive areas). To calculate the amount needed for band application, multiply the broadcast rate by the band width divided by the row width. Wiper applicators are devices that physically wipe appropriate amounts of this product directly onto the weed. On the other hand, delaying application improves weed control but yield loss is unacceptably high (Table 2). begins to drip. Mixing with Water When making at-planting and pre emergent applications, applications must be made before crop emergence to avoid severe crop injury. TANK MIXTURES: In wheat, a tank mix with Aim may be used. Some of the don'ts Don't spray when it's cold, windy, and wet or going to get wet in the next 4 or 5 hours. Droplets, mist, foam or splatter of the herbicide solution settling onto desirable vegetation may result in discoloration, stunting or destruction. Reduced susceptibility to glyphosate or tolerance is inherent in a weed species or population and does not indicate a genetic change as resistance does. MIXING However, the maximum allowed application rates apply to this product combined with the use of any and all other herbicides containing the active ingredient glyphosate, whether applied separately or as tank mixtures, on a basis of total the handler PPE requirements may be reduced or modified as specified in the WPS. Control Solutions, Inc. Use rates and adjuvants can also vary with different glyphosate products, as well as weed species and size. formation in grass or bud formation in broadleaf weeds. If ammonium sulfate is to be used, add it slowly through the screen into the tank, and continue adding water into the tank through the screen. Using tillage or preemerge herbicides should reduce weed density prior to a glyphosate application and help maintain the value of herbicide-tolerant crops. 14.3 Annual Weeds Tank Mixtures with Atrazine for Fallow and Reduced Tillage Systems Pour or pump rinsate into application equipment or rinsate collection system. Time of day of application effect on glyphosate and glufosinate efficacy. Crop Management doi: 10.1094/CM-2003-0219-01-RS. Research indicates that glyphosate performance improves with decreasing spray volume to rates as low as 2.5 gallons per acre (Ramsdale et al. . Therefore, the parent acid or acid equivalent (a.e.) For some reason I was thinking clover. Although considered a non-selective herbicide, some weed species have an inherently high tolerance to glyphosate. is included on the label of the specific product being used in the tank mixture. are likely to drift. Influence of weed removal timing and row spacing on soybean yield loss. 2003. The use of ammonium sulfate is recommended by most product manufacturers; it should be added to the spray solution before glyphosate at 8.5 to 17 lb per 100 gallons of water. - 33 - Application at the V3/V4 stage most often minimizes yield loss while maximizing weed control. to direct the spray onto weed foliage. Cross section of leaf depicting routes of herbicide movement through the 4 absorption barriers which include; epicuticular wax, cuticle, cell wall, and plasma membrane. Application equipment used over the top of desirable vegetation should be adjusted so that the wiper contact point is at least 2 inches above the desirable vegetation. a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 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. Ok you know your spraying 1 acre. Only protected handlers may be in the area during application. quarts of product in 10 or more gallons of water). container on its end and tip back and forth several times. Therefore, adding AMS to the spray solution after adding the glyphosate will do little to improve the herbicide's activity.

Then wash thoroughly and put on clean clothing. Clay, S. A., J. Kleinjan, D. E. Clay, F. Forcella, and W. Batchelor. on this label. Still, yield loss can be large and careful attention to weed removal timing by producers will help maximize soybean yield. seconds after the flow begins to drip. Clean equipment before moving from field to field to minimize the spread of weed seed or plant parts. Environmental conditions, such as extremes in temperature, soil moisture, wind speed, and humidity can enhance or reduce glyphosate absorption and translocation. 2003.

Yield penalty due to delayed weed control in corn and soybean. Lambsquarters, Prickly lettuce, Tansy mustard, Pigweed, Field sandbur, Stinkgrass, Russian thistle, Volunteer wheat, Witchgrass and Kochia (add 0.12 pound of dicamba for control). Control weed escapes and prevent weeds from setting seeds. (e.g. Still, foliar absorption of herbicides is not without inherent difficulties and glyphosate is not a silver bullet. This product may be applied with the following application equipment: Remove contact lenses if present after the first 5 minutes then continue rinsing eye. A comprise may be to apply glyphosate when weeds are six inches tall, although weed removal at that point may only be marginally acceptable for control and yield loss. Foliar-applied herbicides such as glyphosate have the advantage of avoiding the soil environment where colloids, mineral nutrients, and microorganisms can greatly reduce herbicidal activity. 2003). weeds, tree, vine and shrub, pasture grasses, Clean sprayer parts immediately after using this product by thoroughly flushing with water.
