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

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

Allelochemical Potential of Alecrim-de-Campinas (Holocalyx balansae Micheli) on Germination and Growth of Species of Agro-Economic Interest [PDF]

Brazilian Archives of Biology and Technology
Herbicides selects resistant weed populations, such as morning glory (Ipomoea triloba L.) and sourgrass (Digitaria insularis (L.) Fedde). Natural compounds represent an alternative control method for weeds.

Clethodim and photosystem inhibitors on sourgrass control as a function of application time

Revista Ciência Agronômica
This study aimed to evaluate the effects of application time and addition of diuron to clethodim and diquat on the control of sourgrass. Two experiments were conducted with sourgrass plants, applying spray solutions comprising the herbicide clethodim ...

Caracterização anatômica de folha, colmo e rizoma de Digitaria insularis Anatomical characterization of the leaf, stem and rhizome of Digitaria insularis

Planta Daninha, 2008
A anatomia da folha, de colmo e do rizoma de Digitaria insularis foi investigada, visando identificar características que possam estar relacionadas à sua tolerância ao glyphosate. Sementes e rizomas de plantas adultas foram coletadas em campo, em área de

Detection of Sourgrass (Digitaria insularis) Biotypes Resistant to Glyphosate in Brazil

, 2011
Sourgrass is a perennial weed infesting annual and perennial crops in Brazil. Three biotypes (R1, R2, and R3) of sourgrass suspected to be glyphosate-resistant (R) and another one (S) from a natural area without glyphosate application, in Brazil, were ...

Metabolic profiling of glyphosate-resistant sourgrass (Digitaria insularis)

, 2020
Putative 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

Alternatives for the chemical control of sourgrass at post-emergence [PDF]

Pesquisa Agropecuária Brasileira
The objective of this work was to evaluate the effectiveness of herbicides when applied alone and in combinations at sourgrass (Digitaria insularis) post-emergence, as well as to identify a substitute to paraquat in sequential application.
