Impact of glyphosate formulations and adjuvants: effects on leaf interaction, metabolism, and control of sourgrass [PDF]

Ciencia Rural, 2022
: The addition of commercial formulations and adjuvants to a tank mix may result in differences in the wettability on the plant surface, foliar uptake and herbicide efficacy. Thus, the objectives of this study were to evaluate the influence of glyphosate

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 ...

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

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 ...
