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 ...

INTERFERÊNCIA DO CAPIM-AMARGOSO NA CULTURA DA SOJA NO CERRADO BRASILEIRO [PDF]

, 2021
Sourgrass (Digitaria insularis) is one of the main species causing significant losses in Brazilian soybean production systems. Thus, this paper aimed to evaluate sourgrass interference on soybeans grown under Cerrado conditions.

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 ...

Herbicide Resistance in Brazil: Status, Impacts, and Future Challenges [PDF]

, 2020
Brazil is a large producer and exporter of crops in global terms. Weeds may be responsible for ~14% of crop losses, depending on the crop system. Herbicides occupy 58% of the Brazilian pesticide market; however, the continuous use of these products and ...

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.

Allelopathic Potential of Wheat on Sourgrass Resistant to Glyphosate

American Journal of Plant Sciences, 2015
We aimed with this study to assay the allelopathic potential of wheat genotypes in inhibiting germination and initial growth of sourgrass (Digitaria insularis) resistant to the herbicide glyphosate. Two experiments were installed under greenhouse conditions: the first one aimed to assay the potential of wheat genotypes in inhibiting emergence and ...

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 ...
