Microbial rhizosphere communities in response to chlorimuron-ethyl herbicide in soils under alfafa crop
(Sociedade Brasileira de Ciência do Solo, 2022)
Post-Emergence Herbicidal Activity of Nanoatrazine Against Susceptible Weeds
(Frontiers Media Sa, 2018-03-14)
Pot(epsilon-caprolactone) (PCL) nanocapsules have been previously developed as a carrier system for atrazine. However, the efficacy of this nanoformulation against weeds commonly found in crop cultures has not been tested ...
Post-emergent applications of isolated and combined herbicides on corn culture with cp4-epsps and pat genes
(2018-04-01)
For optimum yield, it is necessary to incorporate a good weed control into the system. This study aimed to determine the effects of a post-emergent application of different herbicides (individually and combined) on corn ...
Nanoencapsulation enhances the post-emergence herbicidal activity of atrazine against mustard plants
(Public Library Science, 2015)
Poly(epsilon-caprolactone) (PCL) nanocapsules have been recently developed as a modified release system for atrazine, an herbicide that can have harmful effects in the environment. Here, the post-emergence herbicidal ...
Selectivity of herbicides applied to Brazilian tree species at post-emergence
(Instituto Biológico, 2022-08-29)
The presence of weeds in silvicultural systems has been considered one of the main obstacles to the success of projects designed to recover degraded areas. The aim of this study was to evaluate the selectivity of herbicides ...
Post-emergence application of herbicides and growth regulators on soybean growth and agronomic performance
(2020-06-01)
Plant lodging is among the factors that limit the productive potential of the soybean crop. Growth regulators or even herbicides may be used in pre- and post-emergence of soybean to minimize the chance of lodging. These ...
Uso de herbicidas para o controle de biótipos de Euphorbia heterophylla resistentes a inibidores da PROTOX e ALS
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Ciências AgráriasAgronomiaUTFPR, 2019-11-22)
Euphorbia heterophylla, popularly known as dairy, is a species that has had a major negative impact on annual crops in Brazil, decreasing grain yield and commercial value. In 2004, the first case of multiple resistance of ...
Changes in bacterial communities by post-emergent herbicides in an Andisol fertilized with urea as revealed by DGGE
(2016)
Large amounts of urea and various herbicides are applied to Chilean Andisols by farmers; however, how different herbicide types affect bacterial communities in urea-fertilized soils remains unknown. In this study, the ...
