Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Glyphosate-Resistant Sourgrass Management Programs Associating Mowing and Herbicides [PDF]
: 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

Abstract Premise Previous studies have suggested a trade‐off between trichome density (Dt) and stomatal density (Ds) due to shared cell precursors. We clarified how, when, and why this developmental trade‐off may be overcome across species. Methods We derived equations to determine the developmental basis for Dt and Ds in trichome and stomatal indices (
