USE INSTRUCTIONS: This product may be applied before, during or after planting of cereal crops. Use the 1.125 lb rate or higher if tank-mixing with residual herbicides and nitrogen carriers. labeling, or in separate supplemental labeling for this product. 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. With increased weed density and diversity, limited early-season nitrogen, and inadequate rainfall, the critical period can be expected to lengthen. ensure adequate spray coverage, spray both sides of large or tall woody brush and trees, when foliage is thick and dense, or where there are multiple sprouts. 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. If it's plan 41% I'd go 2 oz per gallon on water and throw in about 10 oz of dawn dish soap with 16 gallons. Active Ingredients: Glyphosate. Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. Apply when wind speeds are 10 miles per hour or less. Drift Reduction Additives Injection Systems Aerial or ground injection sprayers. Repeat applications may be made up to a maximum of 8 quarts of this product Controlled droplet applicators produce a spray pattern that is not easily visible.

Better results may be obtained When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. product by thoroughly flushing with water. Keep and wash PPE separately from other laundry. This is probably in part due to nitrogen fertilization of corn increasing weed competitiveness (Clay et al. Idealized view of herbicide diffusion into a leaf. To calculate the amount needed for band application, multiply the broadcast rate by the band width divided by the row width. Repeat treatments may be necessary to control weeds regenerating from underground parts or seed. Tank mixtures with other herbicides, insecticides, fungicides, micronutrients or foliar fertilizers may result in reduced weed control or crop injury and are NOT specified for applications of this product General Weed Management Recommendations Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control.

Selected glyphosate products and the product use rates for equivalent amounts of glyphosate acid per acre Glyphosate product For best results with ground application equipment, use flat spray nozzles. The standard glyphosate application rate is 0.75 lb a.e. Control weed escapes and prevent weeds from setting seeds. Using tillage or preemerge herbicides should reduce weed density prior to a glyphosate application and help maintain the value of herbicide-tolerant crops. Nozzles with the higher rated flows produce larger droplets. 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. Clean wiper parts immediately after using this Eliminate any risk of siphoning the contents of the tank back into the carrier source while mixing. This product may be diluted in water and applied through shielded sprayers, hooded sprayers, wiper applicators or sponge bars to weeds growing in any non-crop site specified on this label. per gallon of water to control most annual weeds. Significant deflection from the horizontal . sections of this label for further instructions. Knezevic et al. Only the glyphosate parent acid has herbicidal activity, so acid equivalent (a.e.)

Drift reduction additives may be used with all equipment types, except wiper applicators, sponge bars and Controlled Droplet Applicator (CDA) equipment. Step 1. Always, always, always read the label on any chemicals that you use. Older, mature (hardened) annual weed species may require higher rates even if they meet the size requirements. Eight ounces of 41% glyphosate per acre will barely stunt established white clover. Finally, the strongest glyphosate solution. If the hood is raised, spray particles may escape and Figure 1. Ensure that dry the handler PPE requirements may be reduced or modified as specified in the WPS. Purdue University Extension. drip. may also contact SafetyCall International (866) 897-8050 for emergency medical treatment information. 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. Equivalent to 356 grams per liter or 3 pounds per U.S. gallon of the acid, glyphosate. 2004. Timing optima however can vary with weather, weed populations, and cropping management practices. Spray Coverage lowest height that is safe reduces the exposure of the droplets to evaporation and wind. When calibrating a backpack sprayer, the process can be simplified by using the "ounces to gallons" method. Refer to the "ANNUAL Start with a clean field, using either a burndown herbicide application or tillage. Red rice plants with less than 2 true leaves may be only partially controlled. damage or destruction of the plant may result. a.i. In cropping systems, hooded sprayers, shielded sprayers, and wipers may be used in row middles (in between rows of crop plants), and wipers may be used over-the-top of crops only when specified No. For spot spraying, most glyphosate (Roundup) labels will tell you to use about 1.5-2% solution of the concentrate (about 50% glyphosate). Effect of glyphosate application timing and row spacing on corn and soybean yields. per acre? For use in backpack sprayers, it is specified that the appropriate amount of this product be mixed with water in a larger container and then fill the sprayer with the mixed solution.
