Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Degradation of oxyfluorfen in sandy clay loam soil

International Journal of Chemical Studies, 2020
Even though the persistence of oxyfluorfen may be shorter, depends upon the soil, weather and the crop for which it’s being applied, may vary in the oxyfluorfen residues in the soil environment. Considering the above facts, an attempt has been made to study the persistence and degradation of Oxyfluorfen in sandy clay loam soils under laboratory ...

Updated consumer risk assessment of fluoride in food and drinking water including the contribution from other sources of oral exposure

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract This updated risk assessment evaluated evidence on potential adverse health effects of fluoride related to all sources of oral exposure as mandated by the European Commission. Fluoride benefit assessment was not included. Effects on the central nervous system, thyroid and bone were prioritised.

Photochemical behaviour of oxyfluorfen: a diphenyl-ether herbicide

Journal of Photochemistry and Photobiology A: Chemistry, 1999
Abstract The photochemical behaviour in different solvents of the herbicide oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl) benzene (CAS RN 42874–03–3)] was studied. Photochemical reactions were carried out by using a high pressure mercury arc and a solar simulator.
