Growth of canola hybrids resistant and sensitive to herbicides
Durigon, Miria Rosa; Cechin, Joanei; Mariani, Franciele; Silva, Gerarda Beatriz Pinto da; Vargas, Leandro; Chavarria, GeraldoPlant growth analysis is useful for determining adequate management practices and exploring the maximum yield potential of cultivars or hybrids. Canola hybrids with resistance to herbicides have been studied and registered for Brazilian conditions, as they improve weed management in canola crops. This study evaluated the growth of canola hybrids resistant to triazine or imidazolinone herbicides compared to a se...
Interference of volunteer corn in glyphosate resistant soybean and chemical con...
Pertile, Mariane; Cechin, Joanei; Zimmer, Vinicius; Agostinetto, Dirceu; Vargas, LeandroThe successive use of Roundup Ready crops may difficult the management of volunteer plants originated from seed losses during harvest. In soybean, volunteer corn plants can exhibit higher interference and cause reduce yield depending on their density. The aim of this study was to quantify the economic threshold level (ETL) in soybean as a function of the competition of volunteer corn and to evaluate the chemica...
