Multiple-Resistance Evolution to Accase Inhibitors and Glyphosate in Sourgrass (Digitaria insularis) is Attributed to Diverse Polymorphisms in the Herbicide Target Sites

Weed science
Sourgrass [Digitaria insularis (L.) Mez ex Ekman] is considered the most troublesome weed in agronomic crops in South America. Overreliance on glyphosate has selected for resistant populations, although the resistance mechanisms remain unknown. Recently,

Association of quizalofop-P-tefuril to 2,4-D in hairy fleabane (Conyza bonariensis) control: is the antagonism reciprocal to that observed in sourgrass (Digitaria insularis)?

Brazilian Journal of Animal and Environmental Research
The antagonism between auxinic herbicides and graminicides on poaceae weeds is widely known. However, the reciprocal antagonism between these herbicides in the control of eudicots is not known. This study aimed to evaluate the effect of adding quizalofop-

Effectiveness of nanoatrazine in post-emergent control of the tolerant weed Digitaria insularis

Journal of Plant Protection Research, 2020
Digitaria insularis (sourgrass) is a monocotyledon weed of difficult control and high invasive behavior. Atrazine is widely applied in the Americas to control weeds in maize culture, but its efficiency against D. insularis is limited. The incorporation
