Abstract/Contents:"Johnsongrass is a troublesome weed in Texas in most row crops. Glyphosate and SC-0224 have given excellent control of this weed. Previous rates hav enhanced activity when combined with the adjuvant ammonium sulfate. A significant enhancement occurs when the treatments are applied during the summer and fall. No enhancement was observed when applied in the spring or at rates of 0.83 kg/ha acid equivalent and higher. During 1983 and 1984, logarithmic-applications of ammonium sulfate with the rate of SC-0224 or glyphosate held constant showed that rates above 5.55-8.88 kg/ha have an antagonistic effect on Johnsongrass control. There were not differences between SC-0224 and glyphosate at the rate of 0.44 kg/ha a.e. During the fall of 1984, another experiment showed that glyphosate at 0.42 kg/ha a.e. had enhanced activity when combined with various adjuvants. Adjuvants that showed significant enhancement from best to worst were: Frigate = ammonium sulfate, non-ionic surfactant, nor surfactant. At the higher rates of glyposate, these enhancement effects were not evident."
