Weed control and water‐seeded rice response to pyraclonil applied at different timings and in herbicide combinations

Crop, Forage &Turfgrass Management, Volume 10, Issue 1, June 2024.
Abstract Pyraclonil is a new herbicide to control weeds in California water‐seeded rice (Oryza sativa L.). The objectives of this research were to evaluate weed control and rice response from pyraclonil applied alone at different timings and when applied in combinations with other herbicides. In one field study, pyaclonil was applied at 0.3 lbs a.i. ac−

Evaluation and selection of cassava clones and exploitation of genetic covariance across multiple environments

Crop Science, Volume 64, Issue 3, Page 1701-1710, May/June 2024.
Abstract Clonal evaluation trials of cassava (Manihot esculenta Crantz), where the main selection of this crop takes place, are usually carried out in multiple environments. This study investigated the influence of genotype–environment (GE) interaction on selection and how to explore genetic information across environments in a mixed model approach by ...

Assessment of fall‐back MRLs for revoked CXLs previously implemented in the EU legislation and review of the JMPR evaluation of the toxicological data related to pyrasulfotole, pyraziflumid, spiropidion and tetraniliprole

EFSA Journal, Volume 22, Issue 5, May 2024.
Abstract In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to propose fall‐back maximum residue levels (MRLs) for recently revoked Codex MRLs that have been previously implemented in the EU legislation. Overall, MRLs for 12 a.s. are concerned, i.e.

Nanopartículas de alginato como sistema de liberação para o herbicida clomazone

Química Nova, 2010
In this paper, we describe the preparation of alginate nanoparticles as a delivery system for the herbicide clomazone. Two different methods were investigated and characterized by size distribution, zeta potencial, pH and in vitro release.

Removal of clomazone herbicide from a synthetic effluent by electrocoagulation

Water Science and Technology, 2016
AbstractThe aim of this work was to investigate the kinetics of removal of clomazone herbicide from an aqueous solution by electrocoagulation. The experiments were performed in a cylindrical batch reactor with six aluminum electrodes in monopolar mode, arranged in series and connected to a digital DC power.

Efeito da associação do herbicida clomazone a nanoesferas de alginato/quitosana na sorção em solos

Química Nova, 2012
Agrochemicals constitute the class of products most commonly found in water resources. Their high level of concentration is due to the fact that less than 0.1% of pesticides applied to crops reach their target. The present work aims to study the sorption

Efeito do protetor dietholate na seletividade de clomazone em cultivares de arroz irrigado The effect of crop safener dietholate on clomazone selectivity in irrigated rice cultivars

Planta Daninha, 2010
No arroz irrigado, o herbicida clomazone tem sua seletividade variável de acordo com o cultivar, o tipo de solo e a dose aplicada. O uso do protetor dietholate permite seletividade em diferentes ambientes, sendo necessário o estudo da relação entre esses

Seletividade de clomazone isolado ou em mistura para a cultura do algodoeiro Selectivity of clomazone applied alone or in tank mixtures to cotton

Planta Daninha, 2011
O clomazone destaca-se como um dos principais herbicidas utilizados em pré-emergência na cultura do algodoeiro, mesmo levando-se em conta o fato de que muito pouco se sabe em relação à sua seletividade para a cultura.
