Effects of glyphosate and clethodim alone and in mixture in sourgrass (Digitaria insularis)

open access: yesCrop Protection, 2020
Abstract Glyphosate is used frequently in agriculture, and sourgrass (Digitaria insularis (L.) Mez ex Ekman) has become one of the most problematic weeds in Brazil because of its resistance to this herbicide. One of the alternatives for sourgrass control is the use of graminicide alone or in mixture with glyphosate. Thus, this experiment was aimed at

Plant growth and genetic polymorphism in glyphosate-resistant sourgrass (Digitaria insularis L. Fedde)

open access: yesAustralian Journal of Crop Science, 2016
Weed herbicide resistance has been a challenge in agriculture. The objective of this study was to detect sourgrass (Digitaria insularis (L.) Fedde) glyphosate-resistant plants and to evaluate the growth and polymorphism rate between the resistant and susceptible biotypes, as a subsidy for the integrated management of species.

Germination and initial growth of crops and weeds in response to sourgrass aqueous extracts

open access: yesRevista de Ciências Agrárias, 2020
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 ...

Selection of rhizobacteria for pre-emergence control of wild poinsettia, horseweed and sourgrass

open access: yesCientífica, 2019
This study aimed to select rhizobacteria isolates for pre-emergence control of three glyphosate-resistant species: horseweed ( Conyza sumatrensis ), sourgrass ( Digitaria insularis ), and wild poinsettia ( Euphorbia heterophylla ). Nineteen strains of Bacillus spp. and thirty-four strains of Pseudomonas spp. were isolated from soil samples from the
