Abstract Goosegrass [Eleusine indica (L.) Gaertn.] is a difficult‐to‐control grassy weed occurring in compacted soils or heavy‐traffic areas including golf greens. In Florida, goosegrass survives as a short‐lived perennial, and eradication becomes more challenging as the plant matures. Currently, only foramsulfuron (FOR) is registered for postemergence

Abstract Warm‐season turfgrasses, including St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze], are produced and installed as monocultures of single cultivars. Recent research indicates that blending St. Augustinegrass cultivars can increase turfgrass stand resilience to insect pests, establishment of undesired plant species, and abiotic ...

Herbicides selectivity in pre-budded seedlings of sugarcane
: Herbicides are expected to show selectivity towards cultivated plants, i.e., they ought to control weeds without jeopardizing the development and productivity of crops. The objective of this project was to evaluate the selectivity of herbicides applied

Hormesis, a biphasic dose–response phenomenon, occurs when a low dose of a substance stimulates biological activity of an organism while higher doses inhibit it. Glyphosate, the most widely used herbicide in the United States, has frequently been associated with hormetic effects in certain plant species.

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