Allelopathic Potential of Wheat on Sourgrass Resistant to Glyphosate

American Journal of Plant Sciences, 2015
We aimed with this study to assay the allelopathic potential of wheat genotypes in inhibiting germination and initial growth of sourgrass (Digitaria insularis) resistant to the herbicide glyphosate. Two experiments were installed under greenhouse conditions: the first one aimed to assay the potential of wheat genotypes in inhibiting emergence and ...

Alternatives for the chemical control of sourgrass at post-emergence [PDF]

Pesquisa Agropecuária Brasileira
The objective of this work was to evaluate the effectiveness of herbicides when applied alone and in combinations at sourgrass (Digitaria insularis) post-emergence, as well as to identify a substitute to paraquat in sequential application.

Clethodim and photosystem inhibitors on sourgrass control as a function of application time

Revista Ciência Agronômica
This study aimed to evaluate the effects of application time and addition of diuron to clethodim and diquat on the control of sourgrass. Two experiments were conducted with sourgrass plants, applying spray solutions comprising the herbicide clethodim ...

Periods of sourgrass interference in the soybean

Revista Ciência Agronômica
Sourgrass (Digitaria insularis) is one of the principal weeds in Brazil, and there are reports of its being glyphosate-resistant. The aim of this study was to determine the coexistence period of the TMG7063 IPRO soybean cultivar with a weed community ...

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [PDF]

Communications in Plant Sciences, 2014
Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...

Monitoring and baseline of glyphosate-resistant sourgrass in the main soybean growing regions of Brazil

Revista de Ciências Agroveterinárias, 2022
Frequent application of glyphosate for consecutive years has enhanced the selection pressure on sourgrass (Digitaria insularis) populations, which resulted in the development of glyphosate-resistant biotypes.

Herbicide resistance status of sourgrass

Advances in Weed Science, 2023
Abstract Sourgrass [ Digitaria insularis (L.) Mez ex Ekman] is one of the most challenging herbicide-resistant weeds in the grain-producing areas of Southeast, Central-west, and Northeast of Brazil. This species is a perennial grass that is highly competitive with the C4 photosynthetic pathway.

Can Soil Compaction Alter Morphophysiological Responses and Soybean Yield under Application of Selective Herbicides?

Applied and Environmental Soil Science, Volume 2023, Issue 1, 2023., 2023
Compacted soils may be negatively affecting the selectivity of herbicides applied in preemergence in the soybean crop. Therefore, the present work aimed to investigate possible negative effects on the morphophysiological characters of soybean plants, as well as on the agronomic and yield performances of this crop.

INTERFERENCE OF INCREASING DENSITIES OF SOURGRASS IN GRAIN SORGHUM

Revista Brasileira de Milho e Sorgo, 2021
Sourgrass has a high competitive potential, resulting in yield losses of several crops. With the growth of grain sorghum cultivation in the Cerrado , mainly in the second crop, studies are needed to assess the interference of sourgrass on this crop. The objective of this work was to evaluate the interference of increasing densities of sourgrass on ...

Foliar structural differences between glyphosate-resistant and glyphosate-susceptible biotypes of Digitaria insularis (L.) Fedde [PDF]

Revista Ceres, 2023
Digitaria insularis (L.) Fedde stands out for its resistance to glyphosate and this characteristic may have a relationship with structural alterations. In such context, this research aimed at the characterization of the foliar anatomical structure of two
