Read the LIMIT OF WARRANTY AND LIABILITY statement at the end of the label before buying or using. Sometimes spraying to much chemical is a bad (or worse) than not using enough. 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. Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. On the other hand, delaying application improves weed control but yield loss is unacceptably high (Table 2). Velvetleaf stressed by drought or flooding had much greater glyphosate tolerance than non-stressed plants. 27-Apr-12. Plants act to conserve available water during droughty times by thickening epicuticular wax and closing stomata.
