Opis:: In the framework of the performed studies, the antibacterial activity of the following fungicides was evaluated: Miedzian 50 WG (active substance - a.s. 50% copper oxychloride), Ridomil MZ Gold 68 WG (a.s. 3.8% metalaxyl-M and 64%, mancozeb), Euparen Multi 50 WG (a.s. 50% tolylfluanid), Captan 80 WG [a.s. 80% N-(captan)], Dithane Neotec 75 WG (a.s. 75% mancozeb). The evaluation also concerned the essential oils: lavender, sage, lemon balm, clove, and a preparation based on thyme oil (BioZell). Each preparation and compound was tested against the following bacterial pathogens: Erwinia amylovora, Xanthomonas arboricola pv. corylina, X. arboricola pv. juglandis, Pseudomonas syringae pv. syringae, Agrobacterium tumefaciens (presently Rhizobium radiobacter). Each preparation and compound was tested at a concentration of 1,000 ppm of active substance. Copper oxychloride was also tested at a concentration of 1,500 ppm. Among the tested fungicides, metalaxyl-M with mancozeb, mancozeb alone, and copper oxychloride inhibited all of the tested strains of pathogenic bacteria. Tolylfluanid did not inhibit any of the bacteria used. Out of the investigated essential oils, the strongest inhibitors of bacteria were: sage, cloves, and BioZell. The protective activity of the above mentioned fungicides was also evaluated in vivo. They were assessed against fire blight on apple blossoms and pear fruitlets, against bacterial canker on sweet cherry fruitlets, and against crown gall on sunflower seedlings (the test plant). All fungicides were applied at the same concentrations as those in the in vitro tests. Only copper oxychloride was found to show protective activity against the studied diseases. This result indicates that the antibacterial properties of the other fungicides did not correspond with their activity on the plant organs used in the in vivo experiment.

Opis:: Luffa cylindrica M. Roem, is commonly called sponge gourd or Egyptian cucumber. In September 2018, several plants showing symptoms of powdery mildew were observed in some fields at different locations in Egypt. Identification and pathogenicity tests indicated that the causal fungus of powdery mildew disease of luffa cylindrica was Podosphaera xan thii. Results of surveyed luffa plants grown at different field localities of northern Egypt, for powdery mildew disease incidence revealed that the maximum record (57.33%) of dis- ease occurrence was recorded in some fields belonging to Beheira governorate followed by, Alexandria and Sharqia (53.67% and 48.00%, respectively). Meanwhile, fewer occurrences were observed in Kafer El-Sheekh governorate (45.33%). We applied biocontrol agents as a foliar spray against powdery mildew in vitro and under field conditions. The effects of some essential oils, organic acid and bioproducts were also studied. All treatments sig- nificantly reduced P. xanthii compared to untreated plants. Chaetomium globosum and Sac charomyces cerevisiae alone or grown on rice straw and/or bagas showed highly reduced disease incidence compared to the other treatment. From the present study it could be suggested that the usage of biocontrol formulated on rice straw might be used as an easily applied, safe and cost effective control method against powdery mildew diseases.

Opis:: German chamomile (Matricaria recutita (L.) Rauschert) belongs to the plants with a high tolerance to toxic elements. The ability of chamomile to accumulate risk elements was tested in a pot experiment in which four soils contaminated by different levels of arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn), differing in their physicochemical parameters, were used. The element mobility in the soils was affected predominantly by the cation exchange capacity (CEC) of the soils. Whereas As, Pb, and Zn were retained in roots, Cd showed good ability to translocate to the shoots, including anthodia, even in extremely Cd-contaminated soil without symptoms of phytotoxicity. The bioaccumulation factor for Cd calculated as the ratio of element content in the plant and the soil was the highest among the investigated elements. Between 5.5 and 35% of the total Cd was released to infusion, and its extractability decreased with increasing Cd content in anthodia. The essential oil composition suggested an alteration of the abundance of the individual compounds. However, no detectable contents of risk elements were found in the oil. Chamomile can be recommended as a suitable alternative crop for risk element-contaminated soils tested within this experiment, but only for production of essential oil.

Opis:: The samples of stored seeds of pea (Pisum sativum L.) were collected from 30 farmer markets. The mycobiota analysis showed presence of 15 fungal species and one species of insect Callosobruchus chinensis. The fungi such as Aspergillus flavus, A. niger, A. ochraceous, A. terreus were found to be dominant based on percent frequency of each in blotter method in unsterilized and sterilized seeds 18.9–7.9, 15.0–3.9, 12.2–3.7, 10.1–1.7, respectively, and in agar plate technique 17.9–8.3, 15.1–9.5, 12.8–5, 7.9.7–6.7, respectively. These species showed reduction in terms of weight loss, germination and protein content in pathogenicity testing. Essential oil extracted by hydrodistillation from fruits of Cuminum cyminum L. was evaluated against the most common occurring funi such as A. flavus and A. niger as well as the insect species C. chinensis and the oil exhibited high toxicity. The oil killed the tested fungi and showed thermostable nature at its minimum inhibitory concentration (MIC) of 400 ppm. The oil safely preserved pea seeds up to 120 days at 0.50 (1,000 ppm) and 0.76 ml (1,500 ppm) in polyethylene and jute bags of 500 ml capacity containing 400 g seeds separately. There were no changes in organoleptic appereance of food seeds during storage. The oil has beneficial effect on number of visible nodule formation and shoot and root dry biomass of 15-day-old plants in comparison to control sets. The cumin oil was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).

Opis:: Aspergillus parasiticus is one of the most common fungi which contaminates peanuts by destroying peanut shells before they are harvested and the fungus produces aflatoxins. The aim of this study was to evaluate the antifungal activities of seventeen essential oils on the growth of the aflatoxigenic form of A. parasiticus in contaminated peanuts from commercial outlets in Georgia. The agar dilution method was used to test the antifungal activity of essential oils against this form of A. parasiticus at various concentrations: 500; 1,000; 1,500; 2,000; 2,500 ppm. Among the seventeen essential oils tested, the antifungal effect of cinnamon, lemongrass, clove and thyme resulted in complete inhibition of mycelial growth. Cinnamon oil inhibited mycelial growth at ≥ 1,000 ppm, lemongrass and clove oils at ≥ 1,500 ppm and thyme at 2,500 ppm. However, cedar wood, citronella, cumin and peppermint oils showed partial inhibition of mycelial growth. Eucalyptus oil, on the other hand, had less antifungal properties against growth of A. parasiticus, irrespective of its concentration. Our results indicate that the aflatoxigenic form of A. parasiticus is sensitive to selected essential oils, especially cinnamon. These findings clearly indicate that essential oils may find a practical application in controlling the growth of A. parasiticus in stored peanuts.

Opis:: Essential oil of Artemisia annua L. was investigated to find out its toxicity and physiological aspects on the slug Agriolimax agrestis, in controlled conditions (8±1°C, 75±5 RH and 14:10 LD). The slugs received different concentrations of essential oil treated radish leaves in methanol, while the control received methanol alone. LC10, LC30, LC50 and LC90 values were estimated at 4.67, 5.3, 5.81, 7.25%, respectively. The effect of the essential oil on some important enzymatic components like; cytochrome P450 monnooxygenase, acid phosphatase, alkaline phosphatase, lipase, amylase and protease were significantly increased compared to the control. These results indicate that the plant Artemisia annua L. not only shows toxicity but also shows some irreversible effect on some important biochemical components and deserves further investigation.

Opis:: In the study the comparative analysis of test results of drainage of municipal wastewater sludge was conducted with the use of flocculant Praestol 855BS and the mixture of flocculant Praestol 855BS 50% + orange essential oil 50%, as the reagents supporting this process. It was also attempted to reduce unpleasant smells exuding from the drained sludge. The process of drainage of municipal wastewater sludge was conducted in the laboratory setting centrifuge of MPW-350 type. The variable independent parameters were centrifugation time, centrifugation speed, dosage of flocculant Praestol 855BS as well as dosage of mixture in the proportion of flocculant Praestol 855BS (50%) + orange essential oil (50%). The following parameters were subject to assessment: water content in the sludge, dry mass content in the reflux as well as time of maintenance of the oil’s smell in the sludge. The conducted tests demonstrated that the orange essential oil has an impact on drop in resultant quality parameters of the drainage process of municipal wastewater sludge. Batching of the orange essential oil has an impact on considerable reduction of odours exuding from drained wastewater sludge, and thus on improvement of work conditions connected with operation of centrifugal separators. Bearing in mind both the efficient drainage process of wastewater sludge as well as simultaneous reduction of unpleasant smells exuding from the sludge during this process it is assumed and recommended to simultaneously apply both reagents, that is flocculant Praestol 855BS (50%) and orange essential oil, also in the volume of 50%.
W pracy przeprowadzono ocenę porównawczą wyników badań odwadniania komunalnych osadów ściekowych z zastosowaniem flokulanta Praestol 855BS i mieszaniny flokulant Praestol 855BS 50% + olejek eteryczny z pomarańczy 50%, jako odczynników wspomagających ten proces, a także podjęto próbę obniżenia nieprzyjemnych zapachów wydzielających się z odwodnionych osadów. Proces odwadniania komunalnych osadów ściekowych prowadzono w laboratoryjnej wirówce sedymentacyjnej typu MPW-350. Parametrami zmiennymi niezależnymi procesu odwadniania były czas wirowania, prędkość wirowania, dawka fl okulanta Praestol 855BS oraz dawka mieszaniny w proporcji flokulant Praestol 855BS 50% + olejek eteryczny z pomarańczy 50%. Ocenie poddano: zawartość wody w osadzie, zawartość suchej masy w odcieku oraz czas utrzymywania się zapachu olejku w osadzie. Przeprowadzone badania wykazały, że olejek eteryczny z pomarańczy wpływa na spadek parametrów wynikowych, jakościowych procesu odwadniania komunalnych osadów ściekowych. Dozowanie olejku eterycznego z pomarańczy wpływa na znaczne obniżenie odorów wydzielających się z odwodnionych osadów ściekowych, a tym samym na polepszenie warunków pracy obsługi wirówek. Mając na uwadze zarówno efektywny proces odwadniania osadów ściekowych z jednoczesnym zmniejszeniem nieprzyjemnych zapachów wydzielających się z osadów podczas tego procesu, przyjmuje się i zaleca do aplikacji dawkowanie jednoczesne obydwu odczynników, tj. fl okulanta Praestol 855BS 50% oraz olejku eterycznego z pomarańczy także 50% udziału objętościowego.

Opis:: The Mediterranean flour moth, Ephestia kuehniella Zeller, is a major pest of stored grain products, particularly flour. There have been major concerns over the application of conventional insecticides in stored products, which have strongly demonstrated the need for applying such alternative safe compounds as essential oils. The aim of the present study is to investigate the chemical composition and fumigant toxicity of essential oil from Ziziphora clinopodioides Lam. against the eggs, larvae, and adults of E. kuehniella. All toxicity tests were carried out under laboratory conditions set at 26±1°C and 70% relative humidity (RH). The results of gas chromatography- -mass spectrometry (GC/MS) analysis indicated that the essential oil extracted from the leaves of Z. clinopodioides, is rich in pulegone (49.4%), piperitenone (10.7%), menthone (8.9%), and 1,8-cineol (6.9%). Based on the bioassay results, the LC50 value of the tested oil was estimated to be 54.61 μl · l–1 air for larvae and 1.39 μl · l–1 air for adults. Also, it is shown that increasing the oil concentration resulted in a significant increase in oviposition deterrency as well as a considerable reduction in the egg hatching percentage. These results suggest that Z. clinopodioides oil could be a potential candidate as a fumigant for managing E. kuehniella in stored products.

Opis:: The insecticidal properties of essential oil derived via the hydro-distillation method from aerial parts of Artemisia judaica L. were tested against the cowpea weevil, Callosobruchus maculatus (Fab.) (Coleoptera: Bruchidae). The repellent activity assay of essential oil against C. maculates adults indicated that in concentrations of 63.7, 31.9, 15.9, 8.0 or 4.0 μg/cm2, the oil reduced egg laying by 92.5, 86.0, 61.8, 42.7 and 12.5%, respectively. Also, the residual-film assay showed that after 72 hours of treatment, concentrations of 50 and 40% were highly effective against the C. maculates adults. The sub-lethal effects of essential oil were investigated on fecundity and F1 progany by exposing adult females to treated seeds. Both LC25 and LC50 of essential oil significantly reduced F1 progany production compared to the control. The chemical composition of the essential oil was analyzed by GC-MS and the resulting oil piperitone (32.4%), camphor (20.6%) and (E)-ethyl cinnnamate (8.2%) were found to contain the major constituents of the oil. This provided the insecticidal properties of the essential oil against cowpea weevil.

Opis:: Anthracnose disease caused by Colletotrichum lindemuthianum (Sacc. and Magnus) Lams- -Scrib is one of the most devastating seed-borne diseases of common bean (Phaseolus vulgaris L.). In the present study, we evaluated the antifungal activity of Bunium persicum essential oil (EO) and its main constituents on mycelial growth, sporulation and spore germination inhibition of C. lindemuthianum. The main objective of this study was to investigate the effect of EO and its main constituents on decreasing the activity of cell wall degrading enzymes (CWDEs) produced by C. lindemuthianum, which are associated with disease progress. Also, the effects of seed treatment and foliar application of EO and its main constituent, cuminaldehyde, on anthracnose disease severity was investigated. The essential oil of B. persicum, was obtained by using a clevenger apparatus and its major constituents were identified by gas chromatography-mass spectrometry (GC-MS). The EO was characterized by the presence of major compounds such as cuminaldehyde (37.7%), γ-terpinene (17.1%) and β-pinene (15.4%), which indicated antifungal effects against C. lindemuthianum. This pathogen did not grow in the presence of EO, cuminaldehyde and γ-terpinene, β-pinene at 1,500; 1,010 and 1,835 ppm concentrations, respectively. Also, sporulation and spore germination of C. lindemuthianum was completely inhibited by EO and cuminaldehyde. Synergistic effects of the main constituents showed that combing γ-terpinene with cuminaldehyde induced a synergistic activity against C. lindemuthianum and in combination with β-pinene caused an additive effect. Activities of pectinase, cellulase and xylanase, as main CWDEs, were decreased by EO and its main constituents at low concentration without affecting mycelial growth. Seed treatment and foliar application of peppermint EO and/or cuminaldehyde significantly reduced the development of bean anthracnose. We introduced B. persicum EO and constituents, cuminaldehyde and γ-terpinene, as possible control agents for bean anthracnose.
