compounds from decomposing plant material, such as rye (Secale cereale) when used as amulching material.
compounds isolated and identified from weeds.
The relatively short atrazine half-life in grassland soils (8-22 days) suggests the risks of phytotoxic
effects in biofilters is relatively low because concentrations will decline quickly after receiving runoff containing atrazine, and there is a low risk of buildup in soil.
Sorgoleone, a quinone oxidation product of a hydroquinone precursor from root exudates of sorghum, is highly lipophilic, and bioassays show sorgoleone to be more phytotoxic
than phenolics (Netzly et al.
Seedling growth of Thespesia populnea decreased with phytotoxic
metal ions treatments (Pb) at 5, 10, 15, 20 and 25 [micro] mol/L as compared to control.
These products may bind phytotoxic
forms of aluminium in soils and have an acid-ameliorating property (Yazawa et al.
7+] has been shown to be highly toxic in solution culture, but in soils the main phytotoxic
species is [Al.
s persicae) compared with commercial acetogenin-based (Anosom[R] 1 EC) and pyrethrinbased (Insect Spray[R]) bioinsecticides in laboratory and semi-field tests, without having any phytotoxic
effects on the plant species (cabbage and citrus) used in the study.
This low pH, high Al system should elicit a phytotoxic
response in the plant roots, disrupting root elongation and resulting in poor root hair development, limiting the uptake of water and nutrients (Kochian et al.
, insecticidal and leishmanicidal activities of aerial parts of Polygonatum verticiilatum.
However, this practice had been known to have a lot of negative effects, such as plant nutrient immobilization, phytotoxic
(Butler et al.
2011); it also displays phytotoxic
activity (Glinwood et al.
