Population genomics of Digitaria insularis from soybean areas in Brazil [PDF]
Pest Management Science, Volume 77, Issue 12, Page 5375-5381, December 2021., 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 ...

SOURGRASS INTERFERENCE ON SOYBEAN GROWN IN BRAZILIAN CERRADO [PDF]
Revista Caatinga, 2021 ABSTRACT 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. Three field experiments were conducted, of which the first two (E1 and E2) simulated sourgrass after pre-sowing ...

INTERVAL BETWEEN SEQUENTIAL HERBICIDE TREATMENTS FOR SOURGRASS MANAGEMENT [PDF]
Revista Caatinga, 2020 ABSTRACT More than one herbicide application is usually necessary to manage glyphosate-resistant sourgrass in advanced stages of development efficiently during off-season fallow periods. The objective of this study was to determine the best interval between two sequential applications to control sourgrass, based on the number of days and tiller-height ...
