Monitoring and baseline of glyphosate-resistant sourgrass in the main soybean growing regions of Brazil [PDF]

Revista de Ciências Agroveterinárias, 2022
Frequent application of glyphosate for consecutive years has enhanced the selection pressure on sourgrass (Digitaria insularis) populations, which resulted in the development of glyphosate-resistant biotypes.

Population genomics of Digitaria insularis from soybean areas in Brazil. [PDF]

Pest Manag Sci, 2021
An agricultural machine transporting Digitaria insularisacross the country. This represents our results that glyphosate‐resistant D. insularis was likely dispersed via movement of agricultural machinery from the south to the north. Abstract BACKGROUND Digitaria insularis is a weed species that has gained considerable importance in Brazil's soybean ...

Growth inhibition of sourgrass as a function of period of darkness after diquat application [PDF]

Bioscience Journal, 2022
Photosystem-inhibiting herbicides, such as diquat, act by inducing oxidative stress. However, oxidative damage impairs translocation, resulting in regrowth of the plants.

Sourgrass phenological stage and efficacy of ACCase-inhibiting herbicides [PDF]

Planta Daninha, 2020
Background: Sourgrass (Digitaria insularis) is a highly disseminated weed in Brazil. It is a perennial grass weed that has high infesting capacity in agricultural areas and presents glyphosate-resistant biotypes.

Water restriction, salinity and depth influence the germination and emergence of sourgrass [PDF]

Planta Daninha, 2020
Background: Substantial losses to crops can occur due to the presence of sourgrass in agroecosystems, which is promoted by its seed dispersal ability. Environmental factors can affect sourgrass germination and emergence. Objective: The objective of this

Estimating Yield Losses in Soybean Due to Sourgrass Interference [PDF]

Planta Daninha, 2019
: Efficient management of sourgrass is one of the main challenges faced by Brazilian soybean farmers. Biological and ecological characteristics of this weed, as well as wide distribution of glyphosate-resistant biotypes, make it difficult to control this

Reduction of Weed Growth under the Influence of Extracts and Metabolites Isolated from Miconia spp. [PDF]

Molecules, 2022
Weeds pose a problem, infesting areas and imposing competition and harvesting difficulties in agricultural systems. Studies that provide the use of alternative methods for weed control, in order to minimize negative impacts on the environment, have ...

Sourgrass control in response to the association of 2,4-d to ACCase inhibitor herbicides [PDF]

Bioscience Journal, 2020
ACCase inhibitor herbicides are widely used to control poaceae such as sourgrass (Digitaria insularis). However, these herbicides are selective for eudicots, which requires the use of broadleaf herbicides in areas with broadleaf and narrow leaf weeds ...

Target-site mutations Ile1781Leu and Ile2041Asn in the ACCase2 gene confer resistance to fluazifop-p-butyl and pinoxaden herbicides in a johnsongrass accession from Arkansas, USA. [PDF]

Plant Direct
Abstract Johnsongrass [Sorghum halepense (L.) Pers.] is a troublesome weed species in different agricultural and non‐agricultural areas. Because of its biology, reproductive system, and seed production, effective management is challenging. An accession with low susceptibility to the acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides fluazifop‐p ...
