Pre-emergent application of herbicide on sugarcane straw in the control of species of the family Convolvulaceae = Aplicação de herbicidas em pré-emergência sobre palha de cana-de-açúcar para o controle de espécies da família Convolvulaceae

Agro@mbiente On-line, 2015
The mechanised harvesting of sugarcane alters the composition of infesting flora, with the predominance of species of the family Convolvulaceae. The use of herbicide combinations can increase efficiency in controlling these weeds. The aim of this study

Resistance to protoporphyrinogen oxidase inhibitors in giant ragweed (Ambrosia trifida)

Pest Management Science, Volume 80, Issue 12, Page 6211-6221, December 2024.
A codon change in PPX2 conferring a R98L substitution was identified as the most likely mechanism conferring protoporphyrinogen oxidase (PPO)‐inhibitor resistance in Ambrosia trifida. Abstract BACKGROUND Giant ragweed (Ambrosia trifida L.) is one of the most troublesome weed species in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] cropping ...

Adjuvant use for the management of pesticide drift, leaching and runoff

Pest Management Science, Volume 80, Issue 10, Page 4819-4827, October 2024.
Review of laboratory and field research/modelling of adjuvant effects on pesticide drift, leaching and runoff. Adjuvants modifying emulsion/extensional viscosity properties of tank mixes can reduce small droplet fractions of sprays, reducing drift potential with some nozzles. Binding adjuvants can reduce leaching.

Persistence of dicamba residue in harvested soybeans

Agrosystems, Geosciences &Environment, Volume 7, Issue 3, September 2024.
Abstract Adoption of dicamba‐tolerant soybeans contributed to widespread reports of chemical trespassing on adjacent, sensitive soybeans. Reports of the impact of dicamba on sensitive soybeans (Glycine max L.) have been well documented; however, the potential for dicamba carryover into harvested beans from sensitive plants has largely been overlooked ...

Leaching of sulfentrazone herbicide in soils with different textures

Científica, 2016
The objective of this study was to evaluate the leaching potential of sulfentrazone herbicide through bioindicator plants after the occurrence of natural rainfall in soils with clayey and sandy textures. The experimental design was completely randomized in a 3 x 8 factorial with four replications, with three levels of rainfall (30-40, 60-80 and 100-120
