constant use of chemical fungicides has faced to increasing public concern regarding contamination of perishables with fungicidal residues, and proliferation of resistance in the pathogen populations. so recent researches in this area has focused on the development and evaluation of alternative control strategies to reduce dependency on synthetic fungicides. accordingly, in this research in vit...

background: the rice weevil, sitophilus oryzae and rice moth, corcyra cephalonica are major and cosmopolitan insect. adults of s. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. objective: this study was conducted to estimate the insecticidal effect of essential oils from peppermint, mentha piperita l. and black pepper, piper nigrum l. against two m...

Adults of S. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. Objective: This study was conducted to estimate the insecticidal effect of essential oils from peppermint, Mentha piperita L. and black pepper, Piper nigrum L. ag...

throughout the present study, some bacillus spp. were isolated from soil, and the effectiveness of the medicinal plant cuminum cyminum l.’s essential oil extracts were tested against the isolated bacteria. the bacillus spp.were identified through 16s rdna sequence analysis and the antibacterial activity of various organic solvent extracts as well as the essential oils of c. cyminum l. determine...

Increasing bacterial resistance to commercial antibiotics has led to considering medicinal herb applications. This study aimed to identify chemical composition of essential oil of some native medical herbs and their antibacterial activity against Yersinia ruckeri compared with Enrofloxacin in in vitro experiments. The antibacterial activities of ethanolic extracts and essential oils of Eryngium...

  Background : Pseudomonas aeruginosa is one of important opportunistic pathogen, that cases serious infections . It produces many virulence factors, and this bacterium usually is resistance against antimicrobial agents.   Objective :The aim of this study was evaluate the effects of sub-MICs of essential oils of Mentha spicata and Cumminum cyminum on alginate production, biofilm formation, swim...

The insecticidal effects of 20 essential oils derived from herbs, were tested against the housefly species Musca domestica L. using a susceptibility test. Each was applied in ethyl alcohol at concentrations of 1, 5 and 10% (v/v). Ten percent concentrations of Cymbopogon citratus (lemongrass), Mentha piperita (peppermint) and Lavandula angustifolia (lavender) oils were the most effective, showin...

BACKGROUND The aim of the present study was to appraise variation in the chemical composition, and antimicrobial and cytotoxic activities of essential oils from the leaves of four Mentha species-M. arvensis, M. piperita, M. longifolia and M. spicata-as affected by harvesting season. Disc diffusion and broth microdilution susceptibility assays were used to evaluate the antimicrobial activity of ...
