Opis:: The aim of present work was to determine pathogenicity of three Colletotrichum dematium isolates to caraway. The effect of post-culture liquids and water suspension of conidia on germination of caraway schizocarps was studied in laboratory conditions. The effect of C. dematium on shooting up and healthiness of the seedlings was carried out in the climatic chamber using the method with infested soil and solidified plaster of culture medium overgrown by the mycelium of the pathogen. The studied isolates of fungus made the germination of parts of tested schizocarps impossible. On the other hand, all isolates caused necrosis of germs and roots of the other germinated schizocarps. The method with Colletotrichum dematium post-culture liquids was recognized as the best to a fast estimation of pathogenicity of fungus to caraway. Based on the positive results of pathogenicity tests the studied isolates of C. dematium were recognized as pathogenic to caraway. Considering this fact and repeated frequency of isolation of the fungus from various organs of this plant (M a c h o w i c z - S t e f a n i a k , 2010), C. dematium was recognized as a potentially pathogenic species to caraway.

Opis:: The agricultural based economy is a core business in Thailand and food export is one of the main sources of income for the Thai population. However, pesticides are overused and misused. As a result there is an urgent need to reduce the use of synthetic chemicals. Biological control offers an alternative to the use of pesticides. Mango (Mangifera indica L.) is widely planted in Thailand and is one of the major cash crops for international export. However, mango suffers from various diseases especially anthracnose, a fungal disease caused by Colletotrichum gloeosporioides. One hundred and twelve isolates of epiphytic microbes were isolated from healthy leaves and fruits of mangoes; this included 93 and 19 isolates of epiphytic bacteria and yeasts, respectively. They were screened for bioactivity against a pathogenic strain of C. gloeosporioides isolated from diseased mangoes using a dual culture technique. Out of 112 isolates, eight isolates exhibited at least 60% inhibition. These isolates were further screened for their inhibition on mango using fruit inoculation. Two isolates reduced the lesion sizes caused by C. gloeosporioides compared to control treatment. These two isolates, based on phenotypical and biochemical tests, were identified as Bacillus sp. MB61 and Bacillus sp. LB72.

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.

Opis:: In 1999-2001 the effect of sowing method and plant density on the sanitary state of three cultivars of yellow lupine protected with fungicides against diseases was investigated. In spring of 2000 the seedlings on the experimental fields generally withered, which was most likely caused by the applied herbicide, however in 1999 and 2001 seedling black leg (complex of fungi) was reported. The plants germinating from the seeds sown in points were clearly less attacked by pathogens evoking seedling black leg than those sown in rows. The most serious disease of yellow lupine was antracnose (Colletotrichum gloeosporioides). It occurred in all experimental years and its intensity increased during vegetation period. Cultivars of lupine used to the experiment were attacked by Colletotrichum gloeosporioides in a different degree, however, the injury index was mainly determined by weather conditions and the lupine development phase. The applied fungicides significantly limited the development of lupine antracnose. The effect of sowing method and varied plant density on disease intensity was varied.
W latach 1999-2001 przeprowadzono badania dotyczące wpływu sposobu siewu oraz obsady roślin na zdrowotność trzech odmian łubinu żółtego w warunkach chemicznej ochrony przed chorobami. Wiosną 2000 roku na poletkach doświadczalnych wystąpiło ogólne marnienie siewek spowodowane prawdopodobnie działaniem użytego w doświadczeniu herbicydu, natomiast w latach 1999 i 2001 roku odnotowano zgorzel siewek (kompleks grzybów). Rośliny kiełkujące z nasion wysiewanych punktowo były zdecydowanie słabiej atakowane przez patogeny powodujące zgorzel siewek niż siane rzędowo. Najgroźniejszą chorobą łubinu żółtego okazała się jednak antraknoza łubinu (Colletotrichum gloeosporioides). Występowała we wszystkich latach badań, a jej nasilenie w okresie wegetacji wzrastało. Uprawiane w doświadczeniu odmiany były w różnym stopniu atakowane przez Colletotrichum gloeosporioides, jednak indeks porażenia zależał przede wszystkim od przebiegu pogody i fazy rozwojowej łubinu. Zastosowane fungicydy ograniczyły rozwój antraknozy łubinu. Wpływ sposobu siewu i zróżnicowanej obsady roślin na nasilenie choroby był niejednoznaczny.
