effects of mentha arvensis l. and mentha pulegium l. essential oils were investigated against oviposition deterrence, egg hatching and adults' mortality of callosobruchus maculatus f. essential oils were obtained by dry leaves that were subjected to hydrodistilation using a modified clevenger-type apparatus. all experiments were conducted at 25±1ºc, 65±5 % r.h. in the dark condition with 5...

the essential oils of aerial parts of three medicinal plants artemisia khorassanica podl., rosmarinus officinalis l. and mentha longifolia l. were isolated by hydrodistillation and investigated for their toxicity and repellency against tribolium confusum jacquelin du val. at 27 ± 1 ºc and 60 ± 5% rh in darkness. the mortality of the adults increased with concentration from 185 to 1111 μl/l air ...

ecosystem pollution and weed resistance to herbicides have led researchers to pay more attention to natural herbicides. to examine allelopathic effects of liquorice, rosemary, chamomile and eucalypt on germination characteristics and early growth of wheat (triticum aestivum l.) and wild oat (avena fatua l.), a factorial experiment based on completely randomized design with 20 treatments and fou...

post-harvest losses particularly due to fungal invasions, is a major factor in limiting the shelf life of many fruits and vegetables. in order to study the effects of essential oils of thyme (thymus kotschyanus), basil (ocimum basilicum) and rosemary (rosmarinus officinalis) on control of grey mold (botrytis cinerea) disease in pear, a series of in vitro and in vivo (during cold storage of pear...

The chemical composition of the essential oil of Etlingera yunnanensis rhizomes and its contact and repellent activities against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel) were investigated. The essential oil obtained from E. yunnanensis rhizomes with hydrodistillation was performed by gas chromatography-flame ionization detection and gas chromatography-mass spectrome...

to study the effect of essential oils of medicinal plants on post-harvest stability of fruits quality and decay management of kinnow mandarin, this experiment was carried out as factorial in completely randomized design with four replications. essential oils of thyme, mint, fennel, rosemary, ajowan and cummin at two levels 500 and 750 ml/l were applied to wounded and non-wounded fruits, that ha...

Background & Aim: Ziziphora L. genus belongs to the Lamiaceae family, which has important medicinal and aromatic plant species. In current study, essential oil chemical compositions of two Ziziphora L. species (Z. tenuior L. and Z. clinopodioides Lam.) were investigated. Experimental: The flowering branches of Z. tenuior and Z. clinopodioides</e...

Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...
