In vitro acaricide and anticholinesterase activities of digitaria insularis (Poaceae) against Rhipicephalus (Boophilus) microplus

Veterinary Parasitology, 2018
Medicinal plants have been proposed as an alternative for acaricide control, aiming to develop lower-cost and eco-friendly ectoparasiticide products. The aim of this study was to evaluate the in vitro activity of the extracts and fractions obtained from the leaves of Digitaria insularis on the reproductive efficacy of the bovine tick Rhipicephalus ...

EPSPS variability, gene expression, and enzymatic activity in glyphosate-resistant biotypes of Digitaria insularis

Genetics and Molecular Research, 2016
Weed resistance to herbicides is a natural phenomenon that exerts selection on individuals in a population. In Brazil, glyphosate resistance was recently detected in Digitaria insularis. The objective of this study was to elucidate mechanisms of weed resistance in this plant, including genetic variability, allelism, amino acid substitutions, gene ...

Morphophysiological and nutritional responses in maize hybrids competing with Digitaria insularis

Revista Caatinga
ABSTRACT This study aimed to evaluate the competitive interaction between maize hybrids in the presence of Digitaria insularis through experiments in a series of substitutions. The experiments were conducted in a randomized block design with four replicates. Six maize hybrids were used, and the plant density of maize and D.

Pool of resistance mechanisms to glyphosate in digitaria insularis

, 2011
Digitaria insularis biotypes resistant to glyphosate have been detected in Brazil. Studies were carried out in controlled conditions to determine the role of absorption, translocation, metabolism, and gene mutation as mechanisms of glyphosate resistance in D. insularis.
