Effects of atrazine and nicosulfuron on freshwater microalgae

Environment International, 2001
Growth modifications caused by various concentrations of atrazine and nicosulfuron were monitored in closed and continuous culture of Chlorella vulgaris (chlorophyta), Navicula accommoda (diatomophyta), and Oscillatoria limnetica (cyanophyta). The concentration at which algal growth rate was reduced twofold (EC50) was determined in the three species ...

The response of weedy sunflower (Helianthus annuus L.) to nicosulfuron: An examination of vegetative parameters and acetolactate synthase activity [PDF]

Archives of Biological Sciences, 2019
Genetic and morphological interpopulation variability of weed species is often responsible for variable responses to herbicides. As weedy sunflower, an invasive form of Helianthus annuus L., possesses high morphological and genetic variability, very ...

Development and Breeding of Herbicide-Resistant Sorghum for Effective Cereal-Legume Intercropping. [PDF]

Adv Sci (Weinh)
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...

Optimization and Characterization of Nicosulfuron-Degrading Enzyme from Bacillus subtilis Strain YB1

Journal of Integrative Agriculture, 2012
A strain of Bacillus subtilis strain YB1, isolated and preserved in our lab., showed a high nicosulfuron-degrading activity. Optimization of culture conditions on production of nicosulfuron-degrading enzyme from Bacillus subtilis strain YB1 was carried ...

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]

, 2009
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Tolerância de híbridos de milho ao herbicida nicosulfuron [PDF]

Planta Daninha, 2008
Objetivou-se com este trabalho avaliar a tolerância de híbridos de milho ao nicosulfuron e relacionar estudos de seletividade desse herbicida conduzidos em casa de vegetação com estudos desenvolvidos em campo. Em casa de vegetação, o experimento foi conduzido no delineamento de blocos ao acaso, em arranjo fatorial 33 x 3, sendo o primeiro fator ...

Seletividade e dose de injúria econômica de nicosulfuron aplicado em diferentes estádios de desenvolvimento da cultura do milho [PDF]

Ciência Rural, 2001
A tolerância de plantas de milho ao herbicida nicosulfuron é variável em função dos estádios de desenvolvimento da cultura. Um experimento foi conduzido a campo, na EEA-UFRGS, em Eldorado do Sul, com os objetivos de avaliar a seletividade de nicosulfuron
