Enlist volunteer corn affects the crop development and seed quality of Enlist s...
Mazon,Alcimar Spindola; Cechin,Joanei; Piasecki,Cristiano; Gazola,Juliano; Henckes,Jonas Rodrigo; Meneghello,Geri; Agostinetto,DirceuABSTRACT EnlistTM technology is a new trait on soybean and corn conferring tolerance to auxinic-type (2,4-D choline) and graminicides (aryloxyphenoxypropionates – FOPs) herbicides. However, the occurrence of volunteer corn tolerant to 2,4-D and FOPs can become a significant weed on soybean cropping systems, affecting the crop yield and reducing seed quality. This research aimed to evaluate herbicides to EnlistT...
Control of Italian ryegrass and Alexandergrass in corn using different corn sow...
Piasecki,Cristiano; Ovejero,Ramiro Fernando Lopez; Picoli Junior,Gilmar José; Francisco Bellini,Luiz; Agostinetto,Dirceu; Vargas,LeandroABSTRACT Glyphosate-resistant (GR) Italian ryegrass (LOLMU) and Alexandergrass (URPLA) are troublesome weeds in corn cropping systems in Southern Brazil. The emergence pattern of those weeds is not uniform and may change according to the season’s environmental characteristics. Also, herbicide resistance has been diminishing the success of the weed control programs. The objectives of this study were to evaluate ...
Oxidative stress and differential antioxidant enzyme activity in glyphosate-res...
Piasecki,Cristiano; Carvalho,Ivan Ricardo; Cechin,Joanei; Goulart,Francisco A. P; Maia,Luciano Carlos da; Agostinetto,Dirceu; Caverzan,AndréiaABSTRACT Biochemical assays in a time-course were employed to evaluate stresses induced by glyphosate treatment in resistant and sensitive biotypes of Conyza bonariensis. Two experiments were conducted assessing glyphosate doses and time-course after treatment. The doses of glyphosate ranged from 0 to 11840 g ae·ha–1 and assessments performed until 552 h after glyphosate treatment (HAT). The objectives of this ...
