Stratification requirements for seed dormancy alleviation in a wetland weed. [PDF]

, 2013
Echinochloaoryzicola(syn.E. phyllopogon) is an exotic weed of California rice paddies that has evolved resistance to multiple herbicides. Elimination of seedlingsthroughcertain weed control methods can limit the spread of this weed, but is contingent on ...

Herbicide efficacy in relation to herbicide rate, surfactant rate and spray application volume

Proceedings of the New Zealand Plant Protection Conference, 1999
In two experiments, a central composite response surface design was used to investigate the interactions between herbicide rate (glyphosate in Experiment 1 and metsulfuron in Experiment 2), surfactant rate, and spray application volume on tomato dry weight production.

Conned by the enemy: the entomopathogenic fungus Metarhizium anisopliae lures and kills Drosophila suzukii

Pest Management Science, EarlyView.
Highly pathogenic isolates of Metarhizium anisopliae attracted Drosophila suzukii. Identifying the responsible compounds for this attraction could help the development of these isolates for pest monitoring and overall pest management. Abstract BACKGROUND Drosophila suzukii, commonly known as spotted wing drosophila (SWD), is a highly invasive and ...

Could adjuvants serve as an agroecological tool?

Frontiers in Agronomy
Adjuvants are agrochemicals or natural substances, commonly mixed with pesticides to increase their efficacy or reduce off-target movement by modifying the physical properties of the spray solution, such as surface tension, droplet size, and ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
