Conteúdo: | Tebuthiuron was compared to buthidazole and picloram for control of velvet mesquite, catclaw acacia and wait-a-minute bush in field and greenhouse studies. In the field study the effect of tebuthiuron and picloram on forage production and percentage of bare ground was also measured. The greenhouse study tested tebuthiuron and buthidazole as spray and soil applied treatments, and evaluated tebuthiuron and picloram on velvet mesquite and catclaw acacia growing in sand, loam, sand + peat moss and loam + peat moss. In both greenhouse and in field studies the eefectiveness of the herbicidess on the pants increaded with increasing rates of application. However this relationship did not occur in the field study with wait-a-minute bush because this species was heavily damaged by tebuthiuron even at the lowest rate (0.5 lb a.i./acre) of application. In greenhouse both tebuthiuron and buthidazole were more effective as sprays than as soil applied treatments. The same herbicides were more effective on plants growing in sand or loam than on those plants growing in sand + peat moss and loam + peat moss. both herbicides showed the same effectiveness in inhibiting plant growth. In the field study perennial grass production and percentage of bare ground increased with the increasing rate of application. Correlation studies indicated that perennial grass production as the dependent variables was best predicted by the single linear regression equation having the percentage of damaged mesquite as the independent variable (...).
