fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

Depending on the physiological process investigated heavy metal phytotoxicity can be either inhibitory or stimulatory. Photosynthesis and its partial light and dark reactions are inhibited; the activity of various enzymes, located in several cell compartiments, is increased. These enzymes are mostly induced since metals affect the transcription activity. They appear to be related to the plant d...

Introduction Rimon (novaluron, Chemtura Corp.) is an insect growth regulator with activity against a variety of caterpillar pests and whiteflies. It has shown excellent activity against the diamondback moth and should prove useful in resistance management, once it is labeled on cole crops and greens. Recent research has indicated a potential problem with use of novaluron on some greens, as phyt...

Biological screening of Scrophularia nodosa crude extract and its fractions (hexane, chloroform, ethyl-acetate, n-butanol and aqueous) was carried out on phytotoxicity, cytotoxicity, antibacterial, antifungal and analgesic activities. Crude extract and its fractions produced 50-100% phytotoxicity at 1000μ/mL concentration whereas 25-77% phytotoxicity was observed at 10μ/mL concentration. The fr...

Olive oil extraction generates large amounts of olive mill residues (DOR) which may be used as organic fertilizer. The influence of a combination of physical fractionation and saprobe fungal incubation on the phytotoxicity of DOR was studied. The physical fractions of DOR, obtained following extraction using ethyl acetate (EDOR) and water (ADOR) were less phytotoxic than DOR with respect to the...

The aim of the present study was to explore the aerial parts of the Polygonatum verticillatum for various biological activities such as phytotoxic, insecticidal and leishmanicidal properties. Outstanding phytotoxicity was observed for the crude extract and its subsequent solvent fractions against Lemna acquinoctialis Welv at tested doses of 5, 50 and 500 μg/ml. Complete growth inhibition (100%)...

Background: This study investigated the effects of some important meteorological parameters and filler type compounds on phytotoxicity of captan in peach trees in the north of Iran. Captan is a phthalimide fungicide which has frequently been used in northern regions of Iran to control certain plant diseases. This fungicide has caused intense phytotoxicity in peach trees which was first observ...

This study was carried out to evaluate the Brine shrimp lethality (cytotoxicity), antiglycation, phytotoxicity, antiplatelet, antifungal, and antibacterial activities of Ajuga bracteosa. The n-hexane fraction of Ajuga bracteosa was investigated for various biological activities in vitro. Hexane extract showed promising phytotoxicity (100%) at the highest dose only. Interestingly, n-hexane fract...
