Development and application of a bioassay for assessing the dissipation rate of the synthetic strigolactone GR24 in soil

Weed Research, EarlyView.
Abstract Root parasitic weeds of the genera Striga, Orobanche, and Phelipanche cause enormous economic losses for farmers the world over. Germination of the seeds of these species requires a chemotropic signal in the form of strigolactones in the soil.

Environmental release of a safener fenclorim from rice (Oryza sativa L.) following seed treatment

Agricultural &Environmental Letters, Volume 10, Issue 1, June 2025.
Rice seed treatment with fenclorim followed by (fb) insecticide is the best option to minimize the release of fenclorim in soil and ensure the safety of final harvested rice from its residues. Abstract The safener fenclorim, effective in protecting rice (Oryza sativa L.) from the phytotoxicity of some herbicides, is regarded as a contaminant of ...

Photosystem II Is More Sensitive than Photosystem I to Al3+ Induced Phytotoxicity

Materials, 2018
Aluminium (Al) the most abundant metal in the earth’s crust is toxic in acid soils (pH < 5.5) mainly in the ionic form of Al3+ species. The ability of crops to overcome Al toxicity varies among crop species and cultivars. Here, we report for a first time

A dual tank precision sprayer to evaluate the interaction of 2,4‐D choline and quizalofop‐p‐ethyl for control of volunteer corn in corn

Agricultural &Environmental Letters, Volume 10, Issue 1, June 2025.
Abstract Quizalofop‐p‐ethyl (QPE) can control glufosinate/glyphosate‐resistant corn (Zea mays L.) volunteers in corn resistant to aryloxyphenoxypropionates (Enlist corn). Mixing QPE with broadleaf herbicides such as 2,4‐D choline can be antagonistic. A new precision sprayer with a dual tank/boom system can apply two herbicides simultaneously through ...
