Nature, 1952
2 : 3-DICHLORONAPHTHAQUINONE (I) is known to be an effective fungicide. It has been shown to be of value as a seed dressing1; but its use on foliage and fruit is limited because of the possibility of phytotoxic effects2. In an attempt to learn more about the reasons for this damaging action, we have prepared and tested the following compounds for ...

A study on phytotoxicity of alantolactone
Chemico-Biological Interactions, 1971Abstract The phytotoxic action of alantolactone was evident by its inhibitory effects on seed germination, seedling growth, rate of respiration, and degradation of starch and proteins in mung beans (Phaseolus mungo L.). Some amino acids, bases of nucleic acids, and gibberellic acid partially alleviated the alantolactone-induced inhibition of the seed

Phytotoxic activity of kiwifruit leaves and isolation of a phytotoxic substance
Scientia Horticulturae, 2019Abstract When aged kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson) plants are replaced with young ones, the growth and productivity of the young plants were occasionally lower than expected. This symptom is typical of the replant problems reported in several fruit trees. Phytotoxic substances released from the plant are assumed

Science of The Total Environment, 1991
Abstract The effect of 64 priority pollutants on the growth of Lactuca sativa in nutrient solution was determined, and quantitative structure-activity relationships (QSARs) were established relating EC 50 values with octanol/water partition coefficients (log K ow ) of the test chemicals.

Phytotoxicity to and uptake of RDX by rice
Environmental Pollution, 2007Phytoremediation is an emerging strategy to remediate soils contaminated with pollutants like explosives in which plants will uptake, degrade and/or accumulate pollutants. To implement this technology on a site contaminated with RDX, we chose rice, which is able to grow in lagoons, and we tested its ability to grow in soils with high levels of RDX and ...

Phytotoxicity to and uptake of TNT by rice
Environmental Geochemistry and Health, 2008The contamination of the environment by explosives is a worldwide problem resulting in part from 2,4,6-trinitrotoluene (TNT) production. In situ phytoremediation is an appropriate, alternative, cost-effective technology to detoxify extended contamination of surface soil. The ability of rice (Oriza sativa) to both tolerate and assimilate 14C-labeled TNT

Environment and Bromoxynil Phytotoxicity
Weed Science, 1986Experiments in controlled-environment chambers indicated that high temperature, 30 C, increased the phytotoxicity of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to wild mustard (Sinapis arvensisL. # SINAR) and redroot pigweed (Amaranthus retroflexusL. # AMARE) compared to low temperature, 10 C, during and after treatment.

Phytotoxic lignans ofLeucophyllum frutescens
Natural Toxins, 1999Bioassay-guided fractionation of the hexane:ethyl acetate (1:1) extract of the leaves of Leucophyllum frutescens (Berl.) I.M.Johnst (Scrophulariaceae) led to the isolation of its phytotoxic constituents diayangambin (1), epiyangambin (2), diasesartemin (3) and epiashantin (4). Phytotoxicity was demonstrated as inhibition of seed germination of Agrostis

Studies in phytotoxicity: The detection of incipient phytotoxic effects of sulphur preparations
Pesticide Science, 1971AbstractIn a study of the relationship between carbon dioxide assimilation in the light, respiration in the dark, and temperature, the carbon dioxide content of air drawn over dwarf beans treated with lime sulphur or sulphur dust in light or darkness was continuously monitored coulometrically.Sulphur dust had only a negligible effect on carbon dioxide ...

Surfactant-Induced Phytotoxicity
Weed Technology, 1994The leaves of tall morningglory, giant duckweed, and common purslane were treated with nine surfactants at a concentration of 0.1% and examined after 24 hr using cryo-scanning electron microscopy for phytotoxicity as evidenced by tissue damage and epicuticular wax morphology changes.
