Alternatives for chemical management of sourgrass

Bioscience Journal, 2016
Intensive use of Glyphosate has been selected multiple resistant sourgrass biotypes in the areas of intensive agriculture in Brazil. Thus, it is important that viable management alternatives are evaluated for this invasion, which currently is regarded ...

EFFECTS OF ENVIRONMENTAL FACTORS ON SEED GERMINATION AND EMERGENCE OF GLYPHOSATE RESISTANT AND SUSCEPTIBLE SOURGRASS [PDF]

Planta Daninha, 2017
Sourgrass is one of the most problematic weeds of Brazil. It is an aggressive species in the allocation of resources from the environment and reported to be glyphosate resistant in several states of the country.

Growth inhibition of sourgrass as a function of period of darkness after diquat application

Bioscience Journal, 2022
Photosystem-inhibiting herbicides, such as diquat, act by inducing oxidative stress. However, oxidative damage impairs translocation, resulting in regrowth of the plants.

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

Ciencia 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

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 ...

Sourgrass control in response to the association of 2,4-d to ACCase inhibitor herbicides

Bioscience Journal, 2020
ACCase inhibitor herbicides are widely used to control poaceae such as sourgrass (Digitaria insularis). However, these herbicides are selective for eudicots, which requires the use of broadleaf herbicides in areas with broadleaf and narrow leaf weeds ...

Sourgrass densities affecting the initial growth and macronutrient content of coffee plants Densidades de capim-amargoso afetando o crescimento inicial e o teor de macronutrientes do cafeeiro [PDF]

Planta Daninha, 2013
The objective of this work was to evaluate the coexistence effects of coffee (Coffea arabica) with densities of sourgrass (Digitaria insularis) on crop macronutrient content and plant growth.

Effects of glyphosate and clethodim alone and in mixture in sourgrass (Digitaria insularis)

Crop Protection, 2020
Abstract 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 for sourgrass control is the use of graminicide alone or in mixture with glyphosate. Thus, this experiment was aimed at

Periods of sourgrass interference in the soybean

Revista Ciência Agronômica
Sourgrass (Digitaria insularis) is one of the principal weeds in Brazil, and there are reports of its being glyphosate-resistant. The aim of this study was to determine the coexistence period of the TMG7063 IPRO soybean cultivar with a weed community ...

Population genomics of Digitaria insularis from soybean areas in Brazil. [PDF]

Pest Manag Sci, 2021
An agricultural machine transporting Digitaria insularisacross the country. This represents our results that glyphosate‐resistant D. insularis was likely dispersed via movement of agricultural machinery from the south to the north. Abstract BACKGROUND Digitaria insularis is a weed species that has gained considerable importance in Brazil's soybean ...
