Dry Matter and Macronutrient Accumulation in Digitaria insularis Biotypes Susceptible and Resistant to Glyphosate

open access: yesJournal of Agricultural Science, 2019
Herbicide resistant is associated with morphological, physiological and metabolic alterations in weeds. These alterations may reflect changes in the nutritional status of resistant plants and their growth it can be inferred in greater adaptability and competitive ability of the resistant biotypes.

CONTROLE QUÍMICO DE DIGITARIA INSULARIS COM HERBICIDA COMBINADO A DIFERENTES ADJUVANTES

open access: yesRevista Faz Ciência, 2019
O controle de plantas daninhas é uma prática importante para a obtenção de altos rendimentos em culturas agrícolas. O período de entressafra é favorável para a multiplicação de espécies de Digitaria insularis, que é considerado uma planta de difícil controle, o onde se verifica a seleção e a resistência dessas plantas nas lavouras.

Differential response of two sourgrass populations to glyphosate [PDF]

open access: yesCommunications in Plant Sciences, 2013
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 ...

POST-MOWING AND SEQUENTIAL HERBICIDE APPLICATION IN THE MANAGEMENT OF SOURGRASS (Digitaria insularis)

open access: yesChilean journal of agricultural & animal sciences
The excessive use of glyphosate in crop production has led to the emergence of sourgrass (Digitaria insularis) populations resistant to this herbicide. The species has a high capacity for emergence and development throughout the year, making it difficult to control during the off-season. The objective of the this study was to evaluate the effectiveness

Fitness costs on herbicide-resistant Digitaria insularis (L.) Fedde germination.

open access: yesBrazilian journal of biology = Revista brasleira de biologia
Resumo A Digitaria insularis é uma espécie de difícil controle devido a perenização, intensa formação de touceiras e ampla presença de biótipos resistentes a herbicidas. Objetiva-se testar a hipótese que os biótipos de D. insularis com resistência simples ou múltipla aos herbicidas possuem custos adaptativos que influenciam em sua germinação.
