Interference periods of sourgrass (Digitaria insularis) on maize crop

Australian Journal of Crop Science
Sourgrass (Digitaria insularis (L.) Fedde) is frequently reported as one of the main weeds in grain production, along with several reports of herbicide resistance. The objectives of this study were (1) to understand the length of time that the maize crop, cv. P4285VYHR PIONEER could coexist with a weed community dominated by D. insularis plants without

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.

POST-MOWING AND SEQUENTIAL HERBICIDE APPLICATION IN THE MANAGEMENT OF SOURGRASS (Digitaria insularis)

Chilean journal of agricultural & animal sciences
The excessive use of glyphosate in crop production has led to the emergence of sourgrass (Digitaria insularis) populations resistant to this herbicide. The species has a high capacity for emergence and development throughout the year, making it difficult to control during the off-season. The objective of the this study was to evaluate the effectiveness

Ecophysiology of seed germination in Digitaria insularis ((L.) Fedde)

Revista Ciência Agronômica
The invasive behaviour of sourgrass (Digitaria insularis) in cultivated areas is due to its strategy of aggressive regeneration, which is based on seed germination.
