Effect of glyphosate application timing and row spacing on corn and soybean yields. Repeat treatments must be made prior to crop emergence. and carefully observe the precautions, limitations, and all other information appearing on the additive label. Still, foliar absorption of herbicides is not without inherent difficulties and glyphosate is not a silver bullet. Tank mixtures with 2,4-D amine formulations may be applied by air in California for fallow and reduced tillage systems, and for alfalfa and pasture renovation applications only. Application height: Applications must not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required for aircraft safety. If a wettable powder is used, make a slurry with the water, and add it SLOWLY through the screen into the tank while continuing gentle agitation. Colorants or marking dyes may be added to spray solutions of this product; however, they can reduce performance. The international survey of herbicide resistant weeds. Poor field performance of glyphosate can be attributed to a number of environmental conditions or management decisions. When a tank mixture with a generic active ingredient, such as diuron, atrazine, 2,4-D or dicamba, is specified in this label, the user is responsible for ensuring that the specific application being made Annual Weeds Hand-Held or Backpack Equipment per acre), based on this example, growers need to apply 50 percent less of the 4.5 lbs. These procedures will reduce the potential for crop injury: Spray hoods must be operated on the ground or skimming across the ground surface. rate nozzles instead of increasing spray pressure. combined with the rates of this product specified in the ANNUAL WEEDS RATE TABLE (on physical label), will control the following weeds up to the maximum height or length indicated: 6"prickly lettuce, The standard glyphosate application rate is 0.75 lb a.e. The glyphosate, weeds, and crops group. Date: 27-Apr-12. . 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. I am going to order 2 of the 2.5 gallon jugs for a total of $86.30. Drift reduction additives may be used with all equipment types, except wiper applicators, sponge bars and Controlled Droplet Applicator (CDA) equipment. (For example, if the crop row width is 38 inches, the maximum width of the spray hood should be 30 inches.). In fact, weed management tactics need to be concerned with preventing weed interference during the first 4 to 6 weeks after planting (Wood et al. 41 glyphosate application rate per acre. 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. Non-refillable container less than or equal to 5 gallons: Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow Droplets, mist, foam or splatter of the herbicide solution settling onto desirable vegetation may result in discoloration, stunting or destruction. will reduce droplet size and increase drift potential.

Prepare tank mixtures of this product as follows: 1. 1996). Colorants or Dyes 2 Weeds emerging after herbicide application allowed to compete with corn. For example: A 3-pound-per-acre rate requires 3 pounds of herbicide for each crop acre in a broadcast application, but only 1 pound is needed to apply the herbicide in 10-inch bands on 30-inch rows. 1996. To per acre, for 6 to 12 inches use 1.13, and > 12 use 1.50. As density of weeds increases, spray volume should be increased USDA-ERS. For annual weeds over 6 inches tall, or unless otherwise specified, use a 1-percent solution. Refer to label booklet for specific instructions. and timing, refer to the "ANNUAL WEEDSHAND-HELD OR BACKPACK EQUIPMENT" section of this product label. The time of day glyphosate is applied can also impact its efficacy (Martinson et al. And spread lime and fertilizer as needed and yes till it in. Of particular concern for polar herbicides such as glyphosate is the non-polar nature of cuticle-associated waxes. 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.
