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
