Essential oils represent novel alternatives to application of synthetic fungicides to control against seedborne pathogens. This study investigated seven essential oils for in vitro growth inhibition of the main seedborne pathogens of cucurbits. Cymbopogon citratus essential oil completely inhibited mycelial growth of Stagonosporopsis cucurbitacearum and Alternaria alternata at 0.6 and 0.9 mg/mL, respectively. At 1 mg/mL, Lavandula dentata, Lavandula hybrida, Melaleuca alternifolia, Laurus nobilis, and two Origanum majorana essential oils inhibited mycelia growth of A. alternata by 54%, 71%, 68%, 36%, 90%, and 74%, respectively. S. cucurbitacearum mycelia growth was more sensitive to Lavandula essential oils, with inhibition of ~74% at 1 mg/mL. To determine the main compounds in these essential oils that might be responsible for this antifungal activity, they were analyzed by gas chromatography–mass spectrometry (GC-MS). C. citratus essential oil showed cirtal as its main constituent, while L. dentata and L. nobilis essential oils showed eucalyptol. The M. alternifolia and two O. majorana essential oils had terpinen-4-ol as the major constituent, while for L. hybrida essential oil, this was linalool. Thus, in vitro, these essential oils can inhibit the main seedborne fungi of cucurbits, with future in vivo studies now needed to confirm these activities.

<p class="Pa7">The aim of this study was to compare the yield, chemical composition and antifungal activity of the essential oil that is obtained from <em>Mentha pulegium </em>in different developmental stages and cultivated under controlled conditions in southern Brazil. The hydrodistillation of fresh leaves that were collected at 60, 70 and 85 days resulted inessential oil yields of 0.17 %, 0.23 % and 0.17 %, respectively. All of the essential oil samples showed antifungal activity against <em>Cladosporium herbarum</em>. The gas chromatograph (GC) and GC/MS analysis revealed eleven constituents: seven (pulegone, piperitenone, menthone, isomenthone, neoisomenthol, piperitone and 1.1-dimethoxy-2-nonyne) were common to three samples, while menthofuran and myrtenal were detected only in samples of the first and second stages. Pulegone was the main constituent of the essential oil samples from the first and second stages (26.65 %), followed by piperitenone (20.41; 12.60 %). The pulegone concentration increased to 31.05 % in the last collection, while the major constituent was piperitenone (36.32 %). In conclusion, the results demonstrated that <em>M. pulegium </em>essential oil presents potential as an antifungal agent, and its chemical composition depends on the stage of development during which it was extracted.</p>

Investigations on effect of dry root (<i>F. solani</i> var. <i>coeruleum</i> and <i>F. sulphureum</i>) pathogens on three potato cultivares Azalia, Pola, Odra chemical composition were carried out. Content of total nitrogen and protein, total saccharides, reducting and bisaccharides and vit. C was investigated. Significant decrease of total and protein nitrogen content in potatoes affected by <i>Fusarium</i> in relation to intact tubers was found. Moreover increase of reducting saccharides and bisaccharides in potatoes infected by <i>Fusarium</i> compared with controls was observed. Level of vit. C was decreased in tubers affected by <i>Fusarium</i> in all potato cultivars. In this experiment changes in chemical composition content in potato tubers were connected with a kind of dry rot patogen.

Phoma Exigua

The antifungal activity of essential oils against Phoma exigua var foveata, was investigated by analyzing its inhibitory effect on the gangrene of potato tubers. The results showed that mycelium growth and spore germination of Phoma was suppressed by treatment with essential oils, and the inhibitory effect strongly correlated with the concentration of essential oils used in this study. The effectiveness of post-harvest treatment with essential oils was studied for induced resistance to Phoma rot in tubers of two potato varieties (Kolobok and Sante). The results showed the fungicidal effect of cumin and lavender essential oils against phomosis at concentrations of 0.1, 0.2, and 0.4, significant inhibition of mycelium growth (18.1-100%), and viability of conidia (12.8-100%) compared to the control. Moreover, both oils at a concentration of 0.4% caused 100% inhibition of mycelium growth and spore germination. Treatment with oils at a concentration of 0.01-0.04 l/t significantly reduced the degree of damage to tubers infected with phomosis. However, cumin essential oil at a concentration of 0.04 l/t had the greatest effect 97.1% compared to lavender oil 95.4%.

Background: Carthamus caeruleus belongs to the Asteraceae family. The roots are traditionally used as healing agents. They help to heal burns and treat skin diseases. They are also used against joint inflammation and are very effective against diseases such as irritable bowel syndrome for cancer patients. Objectives: The purpose of this work was i) to study the chemical composition of i) the essential oil and hydrosol extract of Carthamus caeruleus, ii) to isolate the major component of both extracts and iii) to evaluate their antioxidant, antifungal and insecticidal activities. Methods: The essential oil and hydrosol extract obtained from the roots were studied by GC and GC/MS. The antioxidant activities were performed using two different methods i) Radical scavenging activity (DPPH) and ii) the Ferric-Reducing Antioxidant Power (FRAP), using BHT as a positive control. Whereas, the antifungal activity of the essential oil and Carlina oxide was investigated against plant fungi. The fumigation toxicity of C. caeruleus essential oil besides Carlina oxide was evaluated against adults of Bactrocera oleae better known as the olive fly. Results: The essential oil and hydrosol extract were mainly represented by acetylenic compounds such as carline oxide and 13-methoxy carline oxide. Carlina oxide was isolated and identified by 1H and 13C NMR spectroscopic means. The results showed that Carlina oxide presented interesting antioxidant and antifungal properties, while C. caeruleus root essential oil had better insecticidal activity. Furthermore, Carlina oxide has demonstrated promising in vivo antifungal activity to control infection of apples by Penicillium expansum. Conclusion: Carlina oxide can be used as a natural food preservative and alternative to chemical fungicides to protect stored apple against Penicillium expansum.
