Before entering the cytoplasm, however, herbicides must diffuse through the cell wall, a primarily hydrophilic environment, and be transported via trans-membrane proteins through the plasma membrane. Environmental Hazards It may be used as a liquid concentrate or diluted prior to injecting into the spray stream. At the standard use rate of 0.75 lb a.e. When a drift reduction additive is used, read . In these instances, repeat treatments may be necessary. Something went wrong. The pubescence on the surface of many weed species can physically limit contact between a leaf surface and a water droplet containing herbicide. Improved control of many tolerant weed species can be obtained by increasing the glyphosate rate and applying to smaller weeds. Do not mix this product with the concentrate However, many factors, including droplet size and equipment type, determine drift potential at any given wind speed. GENERAL PRECAUTIONS, RESTRICTIONS: 2006. 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. This critical weed-free period or critical period is defined as a period of time in crop development that weeds must be controlled to prevent yield loss. DO NOT APPLY DICAMBA TANK MIXTURES BY AIR IN CALIFORNIA. is recommended. Annual Maximum Application Rates Glyphosate is the common name given to the chemical compound N-(phosphonomethyl) glycine; the molecule is a weak acid (parent acid) which can be formulated as any number of salts. 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. Wind to direct the spray onto weed foliage. MIXING The ams is used to help the roundup do its job. Follow manufacturer's instructions for cleaning/maintaining PPE. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 4 hours. Before I plant is it better to burn the dead grass off or work it into the ground? Drift potential is lowest between wind speeds of 2 to 10 mph. 27:38-41. Crop sprayed in treated area will be killed. 9. result in discoloration, stunting or destruction. Proc. Myers, M. W., W. S.

Higher pressure reduces droplet size and does not improve canopy penetration. General Weed Management Recommendations Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. Fill your sprayer or mixer with your desired amount of water. A foliar application should be "rain fast" once droplets have dried on the leaf surface. For better control of common ragweed, giant ragweed, Pennsylvania smartweed, or velvetleaf with a maximum height of 6 inches, tank mix this product with 0.5 pound of 2,4-D per acre. Row width in inches per acre per acre Research indicates that glyphosate performance improves with decreasing spray volume to rates as low as 2.5 gallons per acre (Ramsdale et al. Nozzles with the higher rated flows produce larger droplets. Apply before seed germination in coarse sandy soils to further minimize the risk of injury. WEEDS", "PERENNIAL WEEDS" and "WOODY BRUSH AND TREES RATE SECTIONS" for specific weed recommendations. 2004. The following drift management requirements must be followed to avoid off-target movement during aerial applications to agricultural field crops. Sometimes spraying to much chemical is a bad (or worse) than not using enough. within the specified range to ensure complete coverage. Figure 5 depicts soybean yield loss associated with three row widths. Time to Symptoms a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. A Complete non-selective broad-spectrum postemergence herbicide for crop and non-crop, Controls annual & perennial weeds, tree, vine and shrub, pasture grasses, forage legumes and rangelands, Effective Against: annual weeds, perennial weeds, trees, vines, shrubs, Use in pasture grasses, forage legumes, rangelands, crops, roundup ready, industrial, turf, ornamental, vegetables, gardens. Soybean yield is less affected by weed interference when compared to corn (Dalley et al. Add the specified amount of this product near the end This cloud can move in unpredictable directions due to the light variable winds common during inversions. 2004). Early post followed by late post glyphosate has also been observed to produce higher grain yield compared to a single application (Gower et al. changing or when there are other meteorological conditions that favor spray drift. During mixing, foaming of the spray solution may occur. Narrow-row soybean also reduces weed resurgence, while corn does not share the same benefit (Bradley, 2006). If a flowable formulation is used, premix one part flowable with one part water, and add the diluted mixture SLOWLY through the screen into the tank while continuing gentle 2004. Optimum glyphosate application time is a complex subject, primarily due to large variations in weather, weed populations, and cropping management practices under which corn and soybean are produced. Effects of water quality and spray volume on glyphosate phytotoxicity. altitude and are common on nights with limited cloud cover and light to no wind.

Check nearby stores, Not carried Initial size difference between crops and most Corn Belt weeds due to seed size also tends to delay the onset of the critical period. Red Rice Control Prior to Planting Rice performance. Post-harvest or fallow applications must be made at least 30 days prior to planting any crops not listed When calibrating a backpack sprayer, the process can be simplified by using the "ounces to gallons" method. Non-refillable containers. The following good agronomic practices are specified to reduce the spread of confirmed glyphosate-resistant biotypes: 14.3 Annual Weeds Tank Mixtures with Atrazine for Fallow and Reduced Tillage Systems This product moves through the plant from the point of foliage contact to and into the root system. Contact of this product with desirable vegetation may result in unwanted plant damage or destruction. Always use the higher product application rate within the specified range when weed growth is heavy or dense or when weeds are growing in an undisturbed (non-cultivated) area. Figure 5. Use colorants or dyes according to the manufacturer's recommendations. treated. Using a preplant or preemerge herbicide to be followed by glyphosate reduces its timing sensitivity. Credit 41 Extra is a 4 lb/gallon systemic glyphosate IPA with a proprietary surfactant included for enhanced plant absorption. This is probably in part due to nitrogen fertilization of corn increasing weed competitiveness (Clay et al. Ensure uniform application to avoid streaked, uneven or overlapped application, use appropriate marking devices. If a glyphosate product label specifies the addition of an NIS, ensure it contains at least 80% active ingredient (a.i.) Apply enough total spray volume through the proper equipment to get good coverage of the target 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. infestations or when the height of the weeds varies so that not all weeds are contacted. from the failure of this product to control glyphosate-resistant weeds biotypes. to control most perennial weeds. In these instances, repeat treatment may be necessary. 19:102-107. Unemerged plants arising from unattached underground rhizomes or root stocks of perennials will not be affected by this herbicide and will continue to grow.
