Insecticidal Efficacy of Essential Oils from Cinnamomum zeylanicum, Thymus vulgaris, Ferula assafoetida L on Callosobruchus maculatus F

Introduction: The plants have well-developed defense mechanisms against pests and are excellent sources of new insecticidal substances. Materials and methods: An experiment was conducted on Hamedan Agricultural Research Center, as factorial based on completely randomized blocks in 3 replications during 2009. Experimental treatments included 10 levels concentration with Cinnamomum zeylanicum (0, 5, 10, 15, 20, 25, 75, 100, 200, 300) µl, 7 levels concentration with Thymus vulgaris (0, 0.25, 0.50, 0.75, 10, 20, 30) µl, 6 levels concentration with Ferula assafoetida L (0, 30, 60, 90, 120, 150) µl as the time at 3 levels (8, 24, 48) hours as the second factor. 1 ml of solutiones were applied on filter papers with Whatman No. 1. Then each dried paper was placed and 10 C. maculatus adults was placed. Each set of treatment was repeated 3 times and number of dead insects in was counted at an interval of 8, 24, 48 hours respectively. Conclusion: Percentage mortality was calculated. It has been results that the C. zeylanicum, T. vulgaris, F. assafoetida L essential oils showed 13%, 56%, 10% mortality adult of C. maculatus at dose of 5 µl of C. zeylanicum, 0.25 µl of T. vulgaris, 30 µl of F. assafoetida L respectively. Further concentration increase to 300 µl of C. zeylanicum oil, 30 µl of T. vulgaris, 150 µl F. assafoetida L yielded mortality of 100% against adult C. maculatus respectively.

Abstract: The objective of this work was to assess the fumigant and repellent effects of essential oils on adults of Callosobruchus maculatus and to identify the chemical composition of two of the tested essential oils. For the fumigation test, the oils of Schinus terebinthifolius, Piper aduncum, Syzygium aromaticum, Piper hispidinervum, Cymbopogon citratus, Cinnamomum zeylanicum, and the eugenol compound were tested at different concentrations on C. maculatus adults. For the repellency test, the oils of S. terebinthifolius, P. aduncum, P. hispidinervum, S. aromaticum, Jatropha curcas, and Ricinus communis were evaluated. In the fumigation test, it was observed that P. aduncum and eugenol showed the highest and lowest LC50s, of 169.50 and 0.28 μL L-1 air, respectively. In the repellency test, the oils of S. aromaticum and P. hispidinervum were repellent to C. maculatus. Gas chromatography coupled to mass spectrometry (GC-MS) analysis of these two oils identified 42 compounds, of which safrole was the main component of P. hispidinervum and eugenol of S. aromaticum. The essential oils of S. aromaticum, C. zeylanicum, and the eugenol compound are the most promising to control C. maculatus, via fumigation.

Abstract We assessed the degree to which 16 post-infection treatments controlled Botrytis (Botrytis cinerea Pers. ex. Fr.) damage in cut roses (Rosa × hybrida). Additional experiments examined whether essential oils (EO) of cinnamon (Cinnamomum zeylanicum Blume) leaf (CLO), clove (Eugenia caryophyllata Thunb.) bud (CBO), and thyme (Thymus vulgaris L.) (TO) could reduce damage in Botrytis-infected cut roses. The 16 treatments applied to ‘Light Orlando' cut roses differed in reducing Botrytis damage and causing phytotoxicity damage. Only the synthetic fungicide fludioxonil [applied as 0.23 g · L−1 (0.00024 oz · fl oz−1) Medallion®] resulted in the desirable combination of greatly reduced stem termination frequency due to Botrytis damage and relatively minor flower phytotoxicity. When applied to cut rose ‘Freedom' or cultivars with light colored flowers (‘Cool Water', ‘Jessika', ‘Polar Star', ‘Tiffany'), all EO aqueous solutions caused pronounced phytotoxicity damage, but only TO reduced Botrytis damage significantly compared to untreated flowers. Roses exposed to EO vapor rather than an aqueous solution tended to exhibit less phytotoxicity. Vapors of CLO and CBO tended to reduce Botrytis damage less and caused greater flower phytotoxicity than TO vapor and aqueous fludioxonil. Thyme oil vapor exposures of 4.6 and 9.1 ppm warrant further investigation. Index words: Botrytis blight, Botrytis cinerea Pers. ex. Fr., cut flowers, floriculture, fungicide, gray mold, Rosa × hybrida. Chemicals used in this study: Bacillus subtilis (Cease®), bleach (Clorox®), chlorothalonil (Daconil®), copper sulphate (Phyton® 27), fenhexamide (Elevate®), fludioxonil (Medallion®), hydrogen peroxide (ZeroTol® 2.0), iprodione (Chipco® 26019 Flo), potassium bicarbonate (Milstop®), pyraclostrobin + boscalid (Pageant® Intrinsic®). Species used in this study: Rose (Rosa × hybrida) ‘Cool Water', ‘Freedom', ‘Jessika', ‘Polar Star', ‘Tiffany', Botrytis (Botrytis cinerea Pers. ex. Fr.).

Kinetics Of

Essential oils (EOs) have promising antioxidant activities which are gaining interest as natural alternatives to synthetic antioxidants in the food and cosmetic industries. However, quantitative data on chain-breaking activity and on the kinetics of peroxyl radical trapping are missing. Five phenol-rich EOs were analyzed by GC-MS and studied by oxygen-uptake kinetics in inhibited controlled autoxidations of reference substrates (cumene and squalene). Terpene-rich Thymus vulgaris (thymol 4%; carvacrol 33.9%), Origanum vulgare, (thymol 0.4%; carvacrol 66.2%) and Satureja hortensis, (thymol 1.7%; carvacrol 46.6%), had apparent kinh (30 °C, PhCl) of (1.5 ± 0.3) × 104, (1.3 ± 0.1) × 104 and (1.1 ± 0.3) × 104 M−1s−1, respectively, while phenylpropanoid-rich Eugenia caryophyllus (eugenol 80.8%) and Cinnamomum zeylanicum, (eugenol 81.4%) showed apparent kinh (30 °C, PhCl) of (5.0 ± 0.1) × 103 and (4.9 ± 0.3) × 103 M−1s−1, respectively. All EOs already granted good antioxidant protection of cumene at a concentration of 1 ppm (1 mg/L), the duration being proportional to their phenolic content, which dictated their antioxidant behavior. They also afforded excellent protection of squalene after adjusting their concentration (100 mg/L) to account for the much higher oxidizability of this substrate. All investigated EOs had kinh comparable to synthetic butylated hydroxytoluene (BHT) were are eligible to replace it in the protection of food or cosmetic products.

Bactericidal Properties

Plants produce compounds with antimicrobial properties that can be used to control diseases of horticultural products, for this reason, the aim of this study was to enlarge the knowledge on the effect of essential oils as an alternative for control for bacterial canker Clavibacter michiganensis subsp. michiganensis (Smith) (Cmm). Essential oil of Lippia palmeri was obtained by hydridestillation from plants collected in Sonora, Mexico. Essential oils of Origanum vulgare, Thymus vulgaris and Cinnamomum zeylanicum were obtained from commercial stores in Hermosillo, Sonora, Mexico. To evaluate the effect of the essential oils on the bacterium Cmm, direct applications in two concentrations (1:1 and 1:5 (v/v)) on tomato plants foliage were carried out. Then, plants were inoculated with 1x10-7 CFU/mL of the bacterium and observed for 12 days. The evaluated parameters were incidence and severity. The essential oils and chemical compounds of Origanum vulgare and Thymus vulgaris had effect against Clavibacter michiganensis subsp. michiganensis up to 9 days after application in a 1:1 (v/v) concentration and up to 12 days after application with the 1:5 (v/v) concentration. The essential oil of Lippia palmeri only had effect until six days after the application with both concentrations; that is to say, only these three types of essential oils had bactericidal properties, since with the essential oil of Cinnamomum zeylanicum the inhibition of Cmm was very limited, both in incidence as in severity.
