An in-depth genotypic characterisation of a diverse collection of Digitaria insularis was undertaken to explore the neutral genetic variation across the natural expansion range of this weed species in Brazil. With the exception of Minas Gerais, populations from all other states showed high estimates of expected heterozygosity (HE > 0.60) and geneti...

O capim-amargoso vem se disseminando amplamente no estado de Mato Grosso e, considerando-se os problemas com resistência da espécie a herbicidas no sul do Brasil, neste trabalho objetivou-se identificar possíveis biótipos de capim-amargoso com resistência a herbicidas em Mato Grosso. As coletas ocorreram na região Centro-Sul (2), Norte (90), Sudest...

O último relato de resistência múltipla de Digitaria insularis (capim-amargoso) a inibidores de EPSPs e ACCase em Mato Grosso em 2020, evidenciou a necessidade de monitoramento de resistência a esses mecanismos de ação, devido à sua ampla disseminação pelo vento. Neste trabalho, objetivou-se monitorar biótipos resistentes da espécie aos herbicidas ...

ABSTRACT: Currently, sourgrass is one of the most important weeds in grain production areas in Brazil. The objective of this work was to evaluate the efficiency of associated systems composed by mowing and chemical control against clumped sourgrass. In the first experiment, different mowing heights (0, 5, 10, 15 and 20 cm), coupled with complementa...

Abstract 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 study was to determine the effects of water restriction, salinity, and depth of sowing ...

Abstract 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. An effective post-emergence control of sourgrass plants depends on their phenological stage at the time of herbicide application...

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 species. The objective of this work was to estimate interference of sourgrass in soybean yield. S...

RESUMO Dentre as plantas daninhas com comprovada resistência ao glyphosate, destaca-se o capim-amargoso (Digitaria insularis). O objetivo deste trabalho foi demonstrar que a susceptibilidade de diferentes populações de D. insularis ao glyphosate é consequência do histórico de controle químico adotado nas áreas agrícolas. Sete populações de capim-am...
