Germination test as a fast method to detect glyphosate-resistant sourgrass [PDF]

Bragantia, 2015
The occurrence of weed species with different levels of resistance to glyphosate has increasingly spread in agricultural areas. In Brazil, sourgrass is among the main species presenting issues in this regard. Thus, fast and reliable methods to detect glyphosate resistance are of special interest for this specie, either for research or rational ...

Occurrence of Multiple Glyphosate-Resistant Weeds in Brazilian Citrus Orchards

AgriEngineering, 2023
Glyphosate is the most widely used herbicide for weed control in citrus orchards in Brazil; therefore, it is likely that several species have gained resistance to this herbicide and that more than one resistant species can be found in the same orchard ...

Effectiveness of nanoatrazine in post-emergent control of the tolerant weed Digitaria insularis

Journal of Plant Protection Research, 2020
Digitaria insularis (sourgrass) is a monocotyledon weed of difficult control and high invasive behavior. Atrazine is widely applied in the Americas to control weeds in maize culture, but its efficiency against D. insularis is limited. The incorporation

<b>Glyphosate efficacy on sourgrass biotypes with suspected resistance collected in GR-crop fields [PDF]

Acta Scientiarum. Agronomy, 2018
In Brazil, infestations of crop areas with glyphosate-resistant (GR) sourgrass (Digitaria insularis (L.) Fedde) biotypes has risen significantly, increasing crop production costs. Glyphosate efficacy on three biotypes (GO, BA and MT) of sourgrass with suspected resistance was evaluated. A susceptible biotype (MG) was used as the control.

Allelochemical Potential of Alecrim-de-Campinas (Holocalyx balansae Micheli) on Germination and Growth of Species of Agro-Economic Interest [PDF]

Brazilian Archives of Biology and Technology
Herbicides selects resistant weed populations, such as morning glory (Ipomoea triloba L.) and sourgrass (Digitaria insularis (L.) Fedde). Natural compounds represent an alternative control method for weeds.

Differential susceptibility to glyphosate herbicide and re-growth capacity of different populations of sourgrass

, 2019
Among the proven weeds proven resistance to glyphosate, the sourgrass (Digitaria insularis) stands out. In this sense, this work was developed with the objective of demonstrating that the susceptibility of different populations of D.
