Phytotoxicity of Flumequine on the aquatic weed Lythrum salicaria L. was determined by two laboratory models: a single concentration test, by which the effects of 100 mg l-1 were evaluated after 10, 20, 30 days and a multiple concentration test, by which the effects of 5000-1000-500-100-50 micrograms l-1 were evaluated after 35-day exposure. 100 mg l-1 are highly toxic and significantly decreas...

High Cd concentrations and excess Zn often interfere with mineral nutrients uptake by ion competition as well as affecting membrane permeability (Siedleska, 1995). The induced changes in cell ion homeostasis generally provoke different physiological disorders resulting finally in plant growth inhibition. It has been suggested that Cd and Zn have a similar mode of toxic action (Breckle, 1991; Cl...

A brief overview of biological activity of organotin compounds is given, with emphasis on activity against plant-feeding arthropods. Plictran miticide, containing cyhexatin (tricyclohexylhydroxystannane), the first product to be fully commercialized for control of plant-feeding mites on a broad range of agricultural crops, is used as a model to indicate the chemistry and potential performance, ...

Phytotoxicity including autotoxicity and allelopathy is the immediate or indirect biochemical impact of one organism on germination, growth, survival, reproduction other organisms improvement neighbouring plant species through arrival substances into environment. This biological phenomenon effect might be either growth-enhancing (synergistic) inhibiting (hostile), contingent upon chemical deliv...

Wildflowers attract wildlife, increase pollinator habitat, and enhance the aesthetic value of landscape. Wildflower establishment is increasingly part an effort to reduce maintained turfgrass on golf courses, lawns, other environments. Weed competition decreases wildflower results in poor long-term stands. Research was conducted a controlled environment investigate tolerance species common post...
