Herbicide resistance status of sourgrass

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

Biological Cycle of Susceptible and Glyphosate-Resistant Sourgrass Biotypes in Two Growth Periods [PDF]

Planta Daninha, 2018
ABSTRACT: Selecting glyphosate-resistant Digitaria insularis may cause changes in the biological cycle of the species. Therefore, the objective of this study was to evaluate the biological cycle of susceptible and glyphosate-resistant D. insularis biotypes in two growth periods (summer/autumn and autumn/winter). Seeds were collected in the municipality

Detection of Sourgrass (Digitaria insularis) Biotypes Resistant to Glyphosate in Brazil

, 2011
Sourgrass is a perennial weed infesting annual and perennial crops in Brazil. Three biotypes (R1, R2, and R3) of sourgrass suspected to be glyphosate-resistant (R) and another one (S) from a natural area without glyphosate application, in Brazil, were ...

Growth Analysis of Sourgrass: Does Herbicide Resistance Affect Its Development?

Journal of Agricultural Science, 2019
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. In this way, the aim of this work is to compare the growth of biotypes resistant and susceptible to glyphosate, and

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

Científica, 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 states of

Studies on the biology of sourgrass (Trichachne insularis (L.) Nees) and of its competition with buffelgrass (Cenchrus ciliaris L.) and guineagrass (Panicum maximum Jacq.) [PDF]

, 1975
Sourgrass (Trichachne insularis (L.) Nees) is one of the most serious pasture weeds in Hawaii. It has ruined many good dryland pastures on Maui, Molokai, and Oahu.
