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 ...

Metabolic Responses to Excess Manganese in Legumes: Variations in Nitrogen Compounds in Canavalia ensiformis (L.) DC and Cajanus cajan (L.) Millsp

Legume Science, Volume 6, Issue 3, September 2024.
ABSTRACT Manganese (Mn) is crucial as a trace element for plant metabolism, but high concentrations in soil can induce symptoms of toxicity. This study aimed to evaluate the metabolism of nitrogen compounds and biomass production in Canavalia ensiformis and Cajanus cajan, clarifying the effects of this metal on nitrogen metabolism. The soil was treated
