Population genomics of Digitaria insularis from soybean areas in Brazil. [PDF]
An agricultural machine transporting Digitaria insularisacross the country. This represents our results that glyphosate‐resistant D. insularis was likely dispersed via movement of agricultural machinery from the south to the north. Abstract BACKGROUND Digitaria insularis is a weed species that has gained considerable importance in Brazil's soybean ...

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

Differential response of two sourgrass populations to glyphosate [PDF]
The repetitive use of glyphosate may cause increase on the resistance of sourgrass (Digitaria insularis) through mechanisms of natural selection. The aim of this study was to verify the response of two populations of sourgrass (one collected from ...

Growth Analysis of Sourgrass: Does Herbicide Resistance Affect Its Development?
Sourgrass (Digitaria insularis) is highlighted as one of the most troublesome weeds in Brazilian agriculture. The growth analysis of the species and biotypes with resistance to glyphosate are preponderant to support management strategies.

Germination and initial growth of crops and weeds in response to sourgrass aqueous extracts
Abstract: The objective of this study was to evaluate the allelopathy of aqueous sourgrass extracts on germination and initial growth of cultivated plants and weeds. Two factorial experiments (3x2x3) were carried out, being the plant species (Glycine max (L.), Zea mays (L.), Phaseolus vulgaris (L.), Digitaria horizontalis (W.), Echinochloa crus-galli ...

Target-site mutations Ile1781Leu and Ile2041Asn in the ACCase2 gene confer resistance to fluazifop-p-butyl and pinoxaden herbicides in a johnsongrass accession from Arkansas, USA. [PDF]
Abstract Johnsongrass [Sorghum halepense (L.) Pers.] is a troublesome weed species in different agricultural and non‐agricultural areas. Because of its biology, reproductive system, and seed production, effective management is challenging. An accession with low susceptibility to the acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides fluazifop‐p ...

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

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.

Cytochrome P450 enzymes inhibitor in the control of Digitaria insularis [PDF]
Herbicide interactions can be synergic, additive, or antagonist when mixed in the spray tank. A good example is an association between 2,4-D and graminicides.
