| Weed resistance to herbicides has been a major issue in Brazil, mainly due to the inefficiency of the herbicides used in no-till areas and to the high cost of these herbicide treatments. Failures in controlling the weed Conyza have been reported in Western and Northern grain crop areas in Paraná (Brazil). This work aimed to evaluate the potential occurrence of C. sumatrensis biotypes resistant to the herbicides chlorimuron-ethyl and glyphosate. Experiments were carried out under greenhouse conditions with four biotypes (Cascavel-2, Toledo-4, Tupãssi-6, and Assis Chateaubriand-7) possibly resistant to, as well as a population considered susceptible to chlorimuron-ethyl and glyphosate. To obtain dose-response curves, eight herbicide doses of... |

| Durante la temporada 1998/99 en el Centro Regional de Investigación La Platina del Instituto de Investigaciones Agropecuarias (INIA) (33º34 lat. Sur, 70º38 long. Oeste, 625 m.s.n.m.), en un suelo franco-arcilloso, se realizaron ensayos para determinar la tolerancia de tomate (Lycopersicon esculentum Mill.) de los cultivares industriales H-993, P-76, APT-127, APT-410 y cultivares de consumo fresco Cal Ace y XPH-12221 a aplicaciones de post trasplante de halosulfurón-metil (Sempra® 75 WG) en la dosis recomendada 75 g ha-1 y en sobredosis de 150 y 300 g ha-1. En todas las dosis halosulfurón-metil no produjo síntomas adversos importantes sobre el follaje. Los mayores niveles de decoloración foliar se observaron en la sobredosis 300 g ha-1 en el cv. P-76... |
