Control of Johnson grass patches in cultivation using glyphosate


, : Control of Johnson grass patches in cultivation using glyphosate. Queensland Journal of Agricultural and Animal Sciences 40(2): 95-99

In a field experiment glyphosate applied in Nov. and repeated in Feb. and Apr. resulted in complete control of Sorghum halepense patches in cultivation at concn down to 0.09%. Applications in Nov. repeated in Feb. at concn up to 0.24% or single applications in Nov. or Apr. at concn up to 0.36% failed to completely control the weed. At concn of 0.24% and 0.18% there were no significant differences in initial control achieved irrespective of timing or number of applications.
