NOTE: When using ammonium sulfate, apply this product at rates specified in this label. Source: Iowa State University. per acre per year. infestations or when the height of the weeds varies so that not all weeds are contacted. A review of the effects of row spacing on weed management in corn and soybean. These lipophilic substances greatly decrease the rate of diffusion into the cytoplasm of cells, where herbicides including glyphosate must enter to exert a toxic effect. Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control. Do not reuse or refill this container. Glyphosate effectiveness is dependent on a number of factors; growers armed with this information can readily use it to ensure maximum profitability. When using a 1 percent solution of glyphosate, increase the amount to 1.3 ounces. The ammount of water you use depends on three things: 1. the width of your spray cone coming from the nozzle. Eliminating early-season yield loss by targeting two-inch weeds invites reinfestation by later germinating weeds, some yield loss, and unacceptable weed control. 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. Do not oz of a 41% product). Avoid operating this equipment on rough or sloping terrain where the spray hoods might be raised up off the ground surface. 100.0% 2003) by reducing the competitiveness of weeds (Hock et al. IF IN EYES Hold eye open and rinse slowly and gently with water for 15 - 20 minutes. Movement of photoassimilate (sucrose) and water in plant vascular tissue. Dawn is kind of like the cheap Ammonium sulfate that JEG was talking about. For weeds< 6 inches tall use 0.75 lb a.e. 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. vigorously or recirculate water with pump for 2 minutes. This cloud can move in unpredictable directions due to the light variable winds common during inversions. Our shipping center has {{shippingStoreStock.quantity}} in stock. Red rice plants with less than 2 true leaves may be only partially controlled.

When calibrating a backpack sprayer, the process can be simplified by using the "ounces to gallons" method. 2007). 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 a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Since foliar-applied herbicides move by simple diffusion, maintaining a high concentration gradient improves absorption. In these instances, repeat treatments may be necessary. product be applied at a minimum spray volume rate of 10 gallons per acre. The use of an appropriate residual herbicide will reduce the timing sensitivity of glyphosate and provide residual control until a sufficient crop canopy has formed. In Oregon and Washington, do not exceed 1 pound of atrazine per acre. achieve control. It is used in more than 130 countries on agricultural crops, orchards, nurseries, greenhouses, lawns, landscapes, rights-of-way, etc..

Apply when wind speeds are 10 miles per hour or less. Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. AVOID DRIFT. farmsteads. Better results may be obtained when more of the weed is exposed to the herbicide solution. Adapted from Gower et al. Glyphosate moves with photoassimilate from source (leaf) to sink meristematic regions such as roots (shown) and the shoot (not shown). Only the glyphosate parent acid has herbicidal activity, so acid equivalent (a.e.) Calculate the application rates and ensure that the total use of this and .

Producers can reduce selection intensity by making fewer glyphosate applications. Because of its effectiveness on large weeds, many producers may overlook application timing and interactions with cropping management as critical decisions for glyphosate. For corn production the critical period can begin as early as VE to as late as V7, while the end of the period ranges from V5 to VT. Product Overview. Agron. Ammonium sulfate and a non-ionic surfactant contribute to glyphosate absorption and efficacy; many products include a non-ionic surfactant, however, so carefully consult the appropriate label. Only protected handlers may be in the area during application. Check nearby stores, Cannot be sold in Maintaining a large gradient such as occurs during good growing conditions improves herbicide absorption. Mixing for Hand-Held Sprayers Use low-drift nozzles that provide uniform coverage within the treated area. from the failure of this product to control glyphosate-resistant weeds biotypes. USDA-ERS.

With this method, the amount of spray, measured in ounces, converts directly to gallons per acre. Check action. 2005. If necessary, extend the front and rear flaps of the hooded applicator downward Time of weed removal with glyphosate affects corn growth and yield components. Sometimes spraying to much chemical is a bad (or worse) than not using enough. When higher flow rates are needed, use higher flow The application rate on the label is 28 ounces per acre of either formulation. 2005; Gower et al. Initial size difference between crops and most Corn Belt weeds due to seed size also tends to delay the onset of the critical period. Specific rates of this product that are emphasized in this product's labeling to control Apply to foliage of vegetation to be controlled on a spray-to-wet basis; do not spray to the point of run-off. pasture grasses, forage legumes, rangelands, As density of weeds increases, spray volume should be increased Currently manufacturers of glyphosate formulate it as an isopropylamine, ammonium, or potassium salt. unless otherwise noted in this product label, or in separate supplemental labeling. farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. Repeat this procedure two more times. crops, roundup ready, industrial, turf, For some reason I was thinking clover. When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Idealized view of herbicide diffusion into a leaf. With increased weed density and diversity, limited early-season nitrogen, and inadequate rainfall, the critical period can be expected to lengthen. Oz. With most nozzle types, narrower spray angles produce larger droplets. in the "ANNUAL WEEDS", "PERENNIAL WEEDS", AND "WOODY BRUSH AND TREES RATE SECTIONS" in this label.
