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...

objective: sweet potato whitefly, bemisia tabaci gen. (b. tabaci), is one of the most important pests of various greenhouse crops in iran. nowadays, chemical insecticides are broadly used for control of the pests that causes risk to consumer's health. for the first time, contact toxicity of pelargonium roseum andrews and artemisia sieberi besser essential oils on b. tabaci and its possible...

Germination inhibition activity of N-aryl hydroxamic acids and acetanilide analogues was measured on lettuce seeds (Lactuca sativa). Lipophilicity of the compounds was determined by HPLC. A correlation between lipophilicity values and percentage of germination inhibition was established. A model mechanism of action for auxin was used for analyzing the effect of the substituent at the alpha carb...

A Field experiments were conducted for two years at Agricultural Research Station, Bhavanisagar of Tamil Nadu Agricultural University, Coimbatore, India during kharif season of 2010 and 2011 to evaluate the new formulation of oxyfluorfen (23.5% EC) on weed control in onion and their residual effect on succeeding crops. Herbicides are being chemical in nature, excessive and repeated use may pose...

For routine toxicity testing of composts and growing media, two different types of assays are usually applied. One approach is the use of growing trials in pots with various mixtures of the material. In extract-based tests, seeds are germinated in petri dishes and exposed to an exudate from the material to be tested. In this study, one of these methods, the Phytotoxkit microbiotest, was compare...

Kasugamycin which shows preventive effect on rice blast and low toxicity to plants and animals was discovered in a culture filtrate of Actinomycetes. The study on kasugamycin, as described in a previous paper15, established a new screening method to examine the inhibition of Piricularia oryzae growing in an acidic medium prepared with rice plant juice. Applying this screening method, a new anti...

In order to define the phytotoxic potential of Salvia species a database was developed for fast and efficient data collection in screening studies of the inhibitory activity of Salvia exudates on the germination of Papaver rhoeas L. and Avena sativa L.. The structure of the database is associated with the use of algorithms for calculating the usual germination indices reported in the literature...

Phytotoxicity of Daphne gnidium L. was evaluated through the effect of incorporating leaves, stems and roots biomass into soil (at 12.5, 25, 50g/Kg) and irrigation by their aqueous extracts (50g/L), on the growth of two crops (Lactuca sativa L. and Raphanus sativus L.) and two weeds (Peaganum harmala L. and Scolymus maculatus L.). Results revealed a perceptible phytotoxic effect which increased...

The multicomponent nature of agroecosystem pollution complicates the effectiveness ecotoxicological control. danger combined pesticide and cadmium soil load was investigated in laboratory conditions using agricultural plants (test crops). aim study an integral assessment complex impact contamination on wheat Triticum aestivum L. by biotesting. widely used pesticides agriculture were tested: syst...
