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

Revista Ciência Agronômica, 2014
The invasive behaviour of sourgrass (Digitaria insularis) in cultivated areas is due to its strategy of aggressive regeneration, which is based on seed germination.

Trp2027Cys mutation evolves in Digitaria insularis with cross-resistance to ACCase inhibitors

Pesticide Biochemistry and Physiology, 2020
Sourgrass (Digitaria insularis) is one of the most problematic weeds in South America because glyphosate resistance is widespread across most crop production regions. Acetyl coenzyme A carboxylase (ACCase)-inhibiting herbicides have been intensively used to manage D.

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

Caracterização anatômica de folha, colmo e rizoma de Digitaria insularis Anatomical characterization of the leaf, stem and rhizome of Digitaria insularis

Planta Daninha, 2008
A anatomia da folha, de colmo e do rizoma de Digitaria insularis foi investigada, visando identificar características que possam estar relacionadas à sua tolerância ao glyphosate. Sementes e rizomas de plantas adultas foram coletadas em campo, em área de

Chemical control of different Digitaria insularis populations and management of a glyphosate-resistant population [PDF]

Planta Daninha, 2015
This study aimed to control different populations of Digitaria insularisby glyphosate herbicide, isolated and mixed, besides the combination of methods (chemical and mechanical) to manage resistant adult plants. Three experiments were conducted, one in pots which were maintained under non-controlled conditions and two under field conditions.

RNAi spray-induced gene silencing of EPSPS by topical application of dsRNA in the weed Digitaria insularis [PDF]

Frontiers in Plant Science
The expanding cultivation of grains to meet agro-industry demands, the implementation of more efficient, sustainable, and integrative management practices capable of mitigating the selection of resistant pests and weeds becomes necessary.

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Species-specific effects of post-application relative humidity on glufosinate efficacy and absorption in Bassia scoparia and Chenopodium album. [PDF]

Pest Manag Sci
Glufosinate efficacy and absorption are mediated by post‐application relative humidity duration in Bassia scoparia and Chenopodium album, but the effects are species‐specific. Abstract Background In the semi‐arid United States, where relative humidity (RH) in summer ranges from 25% to 35%, suboptimal glufosinate efficacy is a recurrent issue, but ...
