O potencial de produtividade da cultura do trigo é limitado pela competição exercida pelas plantas daninhas, especialmente pelos recursos luz, água e nutrientes. Em sistemas de produção, a disponibilidade de nitrogênio (N) quase sempre é limi

ABSTRACT: The maximum biological efficiency of a herbicide is performed when the plants are in favorable condition to absorb and metabolize it. Stress situations, such as total submersion, cause stress in plants, reducing weed control efficiency and

ABSTRACT Cyperus iria (CYPIR) is one of the main weeds in irrigated rice crops. The intense chemical control with acetolactate synthase (ALS) inhibiting herbicides favors the selection of cross-resistance. This study aimed to evaluate the crossresist

ABSTRACT Herbicide selectivity in paddy rice varies in several aspects, among which are the environmental conditions. The aim of the study was to evaluate the effect of herbicide application and total plant submersion on morphological and biochemical

ALS-inhibiting herbicides usually provide adequate weed control in irrigated rice fields. After consecutive years of use, the Cyperaceae species, globe fringerush (Fimbristylis miliacea) began to show resistance to ALS (acetolactate synthase) inhibit

Weed biotypes resistant and susceptible to herbicides may have differences in their adaptive values. The aims of this study were to compare, under controlled and non-competitive condition, the growth analysis, germination features and seed weight of
