First report of anthracnose caused by Colletotrichum truncatum on Digitaria insularis in Brazil

, 2023
Digitaria insularis (L.) Fedde (sourgrass) is a perennial monocotyledon weed easily found in soybean fields in Brazil. The emergence of herbicide-resistant sourgrass biotypes is common, making it difficult to control (Gonçalves Netto et al. 2021).

Water regime and straw influence on the effectiveness of preemerging herbicides without control of sourgrass?

, 2022
The control of sourgrass, has been one of the great challenges in the soybean culture, and the pre-emergent herbicides appear as a management option. The objective of this work was to evaluate the control of sourgrass using pre-emergent herbicides positioned under different irrigation regimes and amounts of straw.

Broad spectrum effectiveness of pyroxasulfone + flumioxazin for weed control in pre-emergence of soybean

Revista Agrogeoambiental
It is necessary to search for solutions to control weeds, focusing on pre-emergent herbicides. Pyroxasulfone + flumioxazin is believed to be effective in controlling weeds in soybean, as well as other pre-emergent herbicides used in this crop.

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate

, 2020
Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...
