Effects of glyphosate and clethodim alone and in mixture in sourgrass (Digitaria insularis)
(2020-12-01)
Glyphosate is used frequently in agriculture, and sourgrass (Digitaria insularis (L.) Mez ex Ekman) has become one of the most problematic weeds in Brazil because of its resistance to this herbicide. One of the alternatives ...
Detection of Sourgrass (Digitaria insularis) Biotypes Resistant to Glyphosate in Brazil
(Weed Sci Soc Amer, 2011-04-01)
Sourgrass is a perennial weed infesting annual and perennial crops in Brazil. Three biotypes (R1, R2, and R3) of sourgrass suspected to be glyphosate-resistant (R) and another one (S) from a natural area without glyphosate ...
