Apply before seed germination in coarse sandy soils to further minimize the risk of injury. AVOID APPLYING AT EXCESSIVE SPEED OR PRESSURE. The ams is used to help the roundup do its job. 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. To minimize the occurrence of glyphosate-resistant biotypes observe the following general weed management recommendations: Check You can go with 3 oz if you think you got hard to kill stuff. 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. Thoroughly rinse the spray system with clean water after use to reduce corrosion. Use of drift reduction additives can affect spray coverage, which can reduce product Farm General 41% Glyphosate Grass & Weed Killer is a non-selective, broad-spectrum herbicide for agricultural, residential and industrial use in non-crop areas. A foliar application should be "rain fast" once droplets have dried on the leaf surface. Go and spray your pot with just the water. 2004.

The maximum use rates stated throughout this products labeling apply to this product combined with the use of all other herbicides containing glyphosate as the active ingredient, whether applied as mixtures or separately. Unlike soybean, reducing corn row spacing does not improve its competitiveness (Norsworthy and Oliveira, 2004) and may even reduce it (Dalley et al. Note that at any weed removal time yield loss increases with increasing row width. Rates should be adjusted for weed height by using the standard rate for weeds < 6 inches tall, and increasing the rate by 50 and 100% for weeds between 6 and 12 inches and > 12 inches in height. 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. Unless otherwise specified, weed control applications may be made according to the rates listed With most nozzle types, narrower spray angles produce larger droplets. performance. Selective Equipment Shielded and hooded sprayers, wiper applicators and sponge bars. Repeat applications may be made up to a maximum of 8 quarts of this product restrictions, minimum re-cropping interval and rotational guidelines. Foliar absorption of herbicides occurs in a liquid phase only; once a water droplet has dried on the leaf surface and herbicides have crystallized little to no additional absorption occurs.
