Sensitivity and resistance level of sourgrass population subjected to glyphosate application

Journal of Plant Protection Research, 2021
The intensive use of glyphosate in agricultural areas has increased the frequency of weeds that are resistant to herbicides. Thus, this study was aimed to assess the sensitivity and resistance level of Digitaria insularis (L.) Fedde (sourgrass ...

Germination and Emergence of Digitaria insularis (L.) Fedde Susceptible and Resistant to Glyphosate

Journal of Experimental Agriculture International, 2019
To Know the behavior shown in seed germination and emergence of Digitaria insularis (L.) Fedde enables develop strategies to reduce the seed bank in cultivated areas. The aim of this research was to evaluate the germination and emergence of weed biotypes of D. insularis susceptible and resistant to glyphosate in two substrates. The experiment was

Identificação e controle de biótipos resistentes de Digitaria insularis (L.) Fedde ao glyphosate

Revista Brasileira de Herbicidas, 2015
Em áreas de plantio direto, algumas espécies invasoras têm apresentado potencial para desenvolver resistência ao herbicida glyphosate. Herbicidas inibidores da enzima ACCase podem constituir uma alternativa de controle de biótipos de Digitaria insularis (L.) Fedde resistentes ao glyphosate.

An individual‐based model of seed‐ and rhizome‐propagated perennial plant species and sustainable management of Sorghum halepense in soybean production systems in Argentina

Ecology and Evolution, Volume 9, Issue 17, Page 10017-10028, September 2019., 2019
The paper presented a novel population model for evaluating the effects of ecological, evolutionary, and anthropogenic factors on the population dynamics of perennial plant species. To exemplify the application of the model, a case study of an important weed species, Sorghum halepense, in soybean productions in Argentina was presented.

Non‐target‐site mechanism of glyphosate resistance in Italian ryegrass (Lolium multiflorum)

Weed Biology and Management, Volume 18, Issue 3, Page 127-135, September 2018., 2018
In Shizuoka Prefecture, Japan, glyphosate‐resistant Lolium multiflorum is a serious problem on the levees of rice paddies and in wheat fields. The mechanism of resistance of this biotype was analyzed. Based on LD50, the resistant population was 2.8–5.0 times more resistant to glyphosate than the susceptible population.

Accuracy and consistency of grass pollen identification by human analysts using electron micrographs of surface ornamentation

Applications in Plant Sciences, Volume 2, Issue 8, August 2014., 2014
• Premise of the study: Humans frequently identify pollen grains at a taxonomic rank above species. Grass pollen is a classic case of this situation, which has led to the development of computational methods for identifying grass pollen species.

Spreading and evaporation of glufosinate solution with adjuvants on different weed species [PDF]

Ciência e Agrotecnologia
The addition of adjuvants to herbicides to improve the effectiveness of spray solutions for weed control has been widely adopted. This research aimed to determine the spread, contact angle, and evaporation time of glufosinate, with and without adjuvants,
