Chemical Control and Morphoanatomical Analysis of Leaves of Different Populations of Sourgrass [PDF]

Planta Daninha, 2017
Digitaria insularis has been selected by frequent glyphosate applications both in no-till areas and in fruit orchards. The objective of this paper was to evaluate control efficacy of D. insularis populations by glyphosate, alone and mixed with quizalofop-

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Phloem translocation of strong acids - glyphosate, substituted phosphonic and sulfonic acids - in Ricinus communis L

, 1993
The mobility in phloem of several substituted phosphonic acids and a sulfonic acid was studied in the castor bean plant, Ricinus communis L. For a series of C-14-labelled phosphonate mono-esters applied to the petioles of mature leaves, phloem transport ...

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Correlation of Leaf Damage with Uptake and Translocation of Glyphosate in Velvetleaf (Abutilon theophrasti)

, 1998
Uptake and translocation of glyphosate in three commercial formulations were examined in velvetleaf, a dicotyledonous weed that is commonly treated with glyphosate.

New Case of False-Star-Grass (Chloris distichophylla) Population Evolving Glyphosate Resistance

Agronomy, 2020
Chloris distichophylla, suspected of glyphosate resistance (GR), was collected from areas of soybean cultivation in Rio Grande do Sul, Brazil. A comparison was made with a susceptible population (GS) to evaluate the resistance level, mechanisms involved,

Pesticide Supply Chains From China to Australia: Examining Paraquat Amid the Global Pesticide Complex

Journal of Agrarian Change, EarlyView.
ABSTRACT Following recent calls to deepen understanding of the Global Pesticide Complex, this article delves into the China‐to‐Australia supply chain of a single herbicide—paraquat. First released in the United Kingdom in the 1960s, acutely toxic paraquat is now primarily produced in China.

Photocatalytic degradation of glyphosate using Ce/N co-doped TiO2 with oyster shell powder as carrier under the simulated fluorescent lamp

Frontiers in Environmental Science, 2023
Glyphosate is currently one of the most used organophosphorus herbicides in the world and its accumulation and translocation in soil and wave causes environmental pollution and biological health problems.

Knowledge Work as a Condition of Accumulation in the Pesticide Industry: Syngenta's Defence of Paraquat

Journal of Agrarian Change, EarlyView.
ABSTRACT What do pesticide companies do to keep their products on the market despite strong societal and scientific critiques of their environmental and health risks? This paper examines the herbicide paraquat, one of the most controversial pesticides, from the early 1960s to the present.

The Role of Paraquat (1,1-dimethyl-4,4-bipyridinium chloride) and Glyphosate (n-phosphonomethyl glycine) in Translocation of Metal Ions to Subsurface Soils. [PDF]

Pakistan Journal of Analytical & Environmental Chemistry, 2009
We investigated the role of paraquat (1,1’-Dimethyl-4,4’-bipyridinium dichloride) and glyphosate (N-(phosphonomethyl) glycine), on the translocation of some metals (K, Mg(II), Mn(II), Fe(II), Pb(II), Cu(II) and Cd(II)) in soil, using a topsoil (Aquic ...
