“…Other adjuvants (inert ingredients), such as urea (Li et al 2012) and commercially formulated products, can also be used to counter the effects of hard water. Further, be aware that different commercial glyphosate formulations contain different adjuvants and can vary in efficacy (Chikoye, Lum, and Udensi 2010).…”

Glyphosate is the most used herbicide in the nursery industry in the United States. Used for postemergent control of vegetation, it controls annual and perennial grasses, broadleaves, and sedges. But it is easy to cause unintended damage to desirable vegetation if this product is used incorrectly. This 4-page fact sheet outlines the proper use of glyphosate for plant producers and their employees. Originally Written by Shawn T. Steed and Robert H. Stamps, and published by the UF Department of Environmental Horticulture, May 2012.

“…The results are similar to those of Bekeko (2013), who found that lower concentrations of urea and common salt enhanced the phytotoxicity level of glyphosate on parthenium weed. Similarly, urea phosphate (UPP) as an adjuvant could increase the efficacy of glyphosate and make it possible to achieve effective weed control with glyphosate at lower doses (Pingliang et al 2012).…”

Field experiments were conducted to evaluate the efficacy of glyphosate (H 1 ) and fluazifop--P-butyl (H 2 ) herbicides with adjuvants on the common reed without cutting and at two different cutting levels (10 and 30 cm). The adjuvants were urea, nitric acid and sulfonic acid. The relative importance value (RIV), leaf chlorophyll content and plant density were determined to assay the efficacy of herbicides. Glyphosate treatment only (H 1 a) was more effective than fluazifop-P-butyl (H 2 a) on reeds without cutting and at the 10 cm cutting level. However, no significant difference was observed between them at the 30 cm cutting level. A positive effect of plant cutting occurred on the efficacy of all herbicides applied alone or in a tank mix with adjuvants. Furthermore, the 10 cm cutting level was more effective in eradication of reeds than the 30 cm cutting level. The adjuvants significantly improved the efficacy of the recommended (Hb) and half recommended (Hc) herbicide rates in comparison to being used alone on uncut reeds. The reduction percentages were 94.5, 86.99, 76.61 and 69.94 for H 1 b, H 1 c, H 2 b and H 2 c treatments, respectively. However, the adjuvants did not improve the glyphosate effect at different levels of cutting. Conversely the reduction percentage of reeds was improved by the recommended rate of fluazifop-P-butyl with adjuvants (H 2 b) to 92.77% and 84.62% at 10 and 30 cm cutting levels, respectively.

“…En una formulación líquida de sulfato de amonio el porcentaje usado debe ser equivalente. Otros adyuvantes (ingredientes inertes), como la urea (Li et al 2012) y productos comercialmente formulados, pueden ser usados de la misma forma para contrarrestar los efectos del agua pesada. Adicionalmente, esté consciente que las diferentes formulaciones de glifosato contienen diferentes adyuvantes y pueden variar en eficacia (Chikote et al 2010).…”

El glifosato es el químico de protección para cultivos más vendido en el mundo y el herbicida mós usado en la industria de viveros de plantas en los Estados Unidos. El glifosato es usado para el control post emergente de malezas. Esta publicación describe el uso adecuado de glifosato para los productores de plantas y sus empleados.
