Impact of glyphosate formulations and adjuvants: effects on leaf interaction, metabolism, and control of sourgrass [PDF]

Ciência Rural, 2022
: The addition of commercial formulations and adjuvants to a tank mix may result in differences in the wettability on the plant surface, foliar uptake and herbicide efficacy. Thus, the objectives of this study were to evaluate the influence of glyphosate

ACCase inhibitor fractionation and glyphosate addition improve perennial sourgrass control

Semina: Ciências Agrárias, 2022
Glyphosate-resistant sourgrass is difficult to control, particularly when perennial, and strategies that improve the control efficiency against this grass and preserve the useful life of graminicides are warranted.

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 ...

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [PDF]

, 2014
Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...

Monitoramento e baseline da resistência de capim-amargoso ao herbicida glifosato nas principais regiões produtoras de soja no Brasil [PDF]

, 2022
Frequent application of glyphosate for consecutive years has enhanced the selection pressure on sourgrass (Digitaria insularis) populations, which resulted in the development of glyphosate-resistant biotypes.

Plant growth and genetic polymorphism in glyphosate-resistant sourgrass (Digitaria insularis L. Fedde)

Australian Journal of Crop Science, 2016
Weed herbicide resistance has been a challenge in agriculture. The objective of this study was to detect sourgrass (Digitaria insularis (L.) Fedde) glyphosate-resistant plants and to evaluate the growth and polymorphism rate between the resistant and susceptible biotypes, as a subsidy for the integrated management of species.

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

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.
