Cytochrome P450 enzymes inhibitor in the control of Digitaria insularis [PDF]

Ciência e Agrotecnologia, 2021
Herbicide interactions can be synergic, additive, or antagonist when mixed in the spray tank. A good example is an association between 2,4-D and graminicides.

Sensitivity of Digitaria insularis to herbicides in agricultural areas, in the Brazilian Cerrado biome [PDF]

Pesquisa Agropecuária Brasileira, 2020
: The objective of this work was to evaluate the sensitivity of different populations of Digitaria insularis to the glyphosate, clethodim, and haloxyfop-P-methyl herbicides, in agricultural areas, and to develop infestation maps based on the responses of

Does Sourgrass leaf anatomy influence glyphosate resistance?

Comunicata Scientiae, 2015
Sourgrass(Digitaria insularis, L. Mez ex Ekman)is a weed that requires high rates of glyphosate ((N-[phosphonomethyl]-glycine) forcontrol, verylittle of the herbicide applied isabsorbed by theleaves. Morphological and histological differences in leaves of glyphosate-resistant and glyphosate-susceptible plantsshould explain the contrast of variance ...

Metabolic profiling of glyphosate-resistant sourgrass (Digitaria insularis)

Weed Technology, 2020
AbstractPutative glyphosate-resistant sourgrass was collected to determine its resistance level and to evaluate its metabolic profile after resistance. Although accumulation of shikimic acid is known to occur in glyphosate-susceptible populations, differences in the ability of resistant (R) and susceptible (S) biotypes to accumulate quinic acid ...

Growth and Development of Digitaria insularis Biotypes Susceptible and Resistant to Glyphosate [PDF]

Planta Daninha, 2017
The study aimed to evaluate the growth and development of biotypes of Digitaria insularis susceptible and resistant to glyphosate. Samples of biotypes were collected in Western Paraná in Cascavel, one susceptible (24o57'29.06" S and 53o30'23.73" W) and ...

CHEMICAL CONTROL OF ADULT SOURGRASS IN COFFEE CROPS, THROUGH VARIOUS ASSOCIATIONS

Scientia Agraria Paranaensis, 2021
Weed management in coffee plants is carried out largely through the adoption of chemical control, with the use of herbicides. In this context, one of the species that most affects the development of coffee plants, and due to its difficulty in control, is sourgrass.

Anthracocystis panici-leucophaei: A Potential Biological Control Agent for the Grassy Weed Digitaria insularis

Agronomy
Anthracocystis panici-leucophaei, causal agent of smut on Digitaria insularis (sourgrass), was evaluated as a biological control agent for this weed. Two types of inocula (teliospore and sporidia) were tested to assess its infectivity.

Occurrence of Multiple Glyphosate-Resistant Weeds in Brazilian Citrus Orchards

AgriEngineering, 2023
Glyphosate is the most widely used herbicide for weed control in citrus orchards in Brazil; therefore, it is likely that several species have gained resistance to this herbicide and that more than one resistant species can be found in the same orchard ...

Chemical management of sourgrass with mixture of herbicides in areas under no-tillage system

Scientia Agraria Paranaensis, 2021
The sourgrass [Digitaria insularis (L.) Fedde] is a native species of the Americas found in tropical and subtropical regions, the difficulty in controlling Digitaria insularis with the herbicide Glyphosate generates the need to use other herbicides for an adequate management of the species.

Effectiveness of nanoatrazine in post-emergent control of the tolerant weed Digitaria insularis

Journal of Plant Protection Research, 2020
Digitaria insularis (sourgrass) is a monocotyledon weed of difficult control and high invasive behavior. Atrazine is widely applied in the Americas to control weeds in maize culture, but its efficiency against D. insularis is limited. The incorporation
