Soybean yield is less affected by weed interference when compared to corn (Dalley et al. Higher pressure reduces droplet size and does not improve canopy penetration. seconds. So, use 2.7 ounces of glyphosate 41 for a solution of 2 percent. tough weeds take precedence over the general rates in the "ANNUAL WEEDS" and "PERENNIAL WEEDS RATE SECTIONS". Crop injury may occur when the foliage of treated weeds comes into contact with leaves of the pasture grasses, forage legumes, rangelands, if you add oil or other mixing ingredients to your mixing tank.

Apply to foliage of vegetation to be controlled on a spray-to-wet basis; do not spray to the point of run-off. 5. Corn may be planted 7 days after application at the 2 oz per acre rate (requires minimum of 25% surface residue and 0.25 inch of rainfall between . to control most perennial weeds. Humidity", and "Temperature Inversions"). Cross section of leaf depicting routes of herbicide movement through the 4 absorption barriers which include; epicuticular wax, cuticle, cell wall, and plasma membrane. Apply this product only when the potential for drift to adjacent sensitive areas (e.g. Additionally, altering cropping management practices to reduce the number of individuals exposed to glyphosate can further decrease selection intensity. Crop injury may occur when foliage of treated weeds comes into direct contact with leaves of the crop. Maintain gentle agitation at all times until the contents of the tank are sprayed out. Repeat applications may be made up to a maximum of 8 quarts of this product Nozzles must always point backward, parallel with the air stream and never be pointed downwards more than 45 degrees.

First what does your hayland comprise of? 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 Agron. droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under unfavorable environmental conditions (read the following sections on "Wind", "Temperature and be avoided when wind speeds are below 2 mph due to variable wind direction and high inversion potential. 41 glyphosate application rate per acre Tagi. When using a 1 percent solution of glyphosate, increase the amount to 1.3 ounces. This pesticide contains 8 lbs. 6. Observe all labeled safeguards until container is cleaned, reconditioned, or destroyed. And spread lime and fertilizer as needed and yes till it in. Have the product container or label with you when calling a poison control center or doctor, or going for treatment. Colorants or marking dyes may be added to spray solutions of this product; however, they can reduce performance. Thoroughly clean equipment before leaving fields known to contain resistant biotypes. The most effective way to reduce drift-potential is to apply large droplets. NOTE: Local terrain can influence wind patterns. gentle agitation. Plants act to conserve available water during droughty times by thickening epicuticular wax and closing stomata. Bradley, K. W. 2006. Apply to actively growing annual weeds. a selective and/or a residual herbicide) and cultural practices (e.g. It may be applied through most standard industrial or field sprayers after dilution and thorough mixing with water or other carriers according to label instructions. Pioneer Hi-Bred Intl, Inc. Johnston, Iowa. Wiper Applicators The effect of weed density and application timing on weed control and corn grain yield. Table 1. WEEDS", "PERENNIAL WEEDS" and "WOODY BRUSH AND TREES RATE SECTIONS" for specific weed recommendations. Products including surfactants are often said to be "fully loaded" and usually dont require the addition of a non-ionic surfactant (NIS), however, manufacturers are not required to provide that information so the product label should be consulted. 1996). Temperature Inversions Wiper Application (Feed Barley and Wheat only), Preharvest (Wheat And Feed Barley Only). Oz. One method for adding other herbicides into a continuous Roundup Ready system is to rotate to other Roundup Ready crops. Ammonium sulfate reduces the antagonistic effect of hard water on glyphosate. crops, roundup ready, industrial, turf, 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 Applications must not occur during a temperature inversion because drift potential is high. of this label. ;-). Control weed escapes and prevent weeds from setting seeds. 10109579. Effect of glyphosate application timing and row spacing on corn and soybean yields. 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. Do not tank mix with soil residual herbicides when using these rates unless otherwise specified. Control weeds early when they are relatively small. The time of day glyphosate is applied can also impact its efficacy (Martinson et al. Band width in inches X Broadcast VOLUME of solution = Band VOLUME of solution The ams is used to help the roundup do its job. Hold container Comply with all State regulations where applicable.

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. Extreme care must be taken to avoid spray or drift onto the foliage or any other green tissue of desirable vegetation, as Step 1. A single, low pressure low-drift flat-fan nozzle with an 80 to 95 degree spray angle positioned at the top to direct the spray onto weed foliage. Best control of most perennial weeds is obtained when treatment is made at late growth stages approaching maturity. Figure 3.

Using a preplant or preemerge herbicide to be followed by glyphosate reduces its timing sensitivity. To 2003; Knezevic et al. Some claim rain fast in a hour. See the "INGREDIENTS" section of this label for necessary product information. The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. By: sagittarius. The portion of any glyphosate product with herbicidal activity is the parent acid (Figure 4). Better results may be obtained when more of the weed is exposed to the herbicide solution. 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. 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. To determine whether your county or pounds of glyphosate (acid equivalents) per acre. Some items may vary from photos.
