The infectious process of Ramularia areola, the causal agent of ramularia leaf spot, on leaves of cotton, Gossypium hirsutum L. (Malvaceae), was studied by using the scanning electron microscope. Conidia started to germinate at 12 hours after inoculation (hai) and no appressoria were observed at this time. In most cases, conidia germinated and produced two germ tubes that grew towards the stomata where the penetration occurred. Fungus sporulation occurred at both adaxial and abaxial leaf epidermis through the stomata. Fungal hyphae suscefully colonized the mesophyll cells both inter and intra cellularly. Disease symptoms appeared at 12 dai with severity level of 1%, but reached 32% at 22 dai.
O processo infeccioso de Ramularia areola, o agente causal da mancha da ramulária, em folhas de algodoeiro, Gossypium hirsutum L. (Malvaceae), foi estudado utilizando a microscopia eletrônica de varredura. Os conídios iniciaram a germinação 12 horas após a inoculação (hai) e nenhum apressório foi observado nesse período. Na maioria dos casos, os conídios germinaram e produziram dois tubos germinativos que cresceram através dos estômatos onde a penetração ocorreu. A esporulação do fungo ocorreu em ambas as faces adaxial e abaxial da epiderme foliar através dos estômatos. As hifas do fungo colonizaram com sucesso as células do mesófilo inter e intra celularmente. Os sintomas da doença apareceram em 12 dai com um nível de severidade de 1%, porém alcançaram 32% em 22 dai.

Full textThe main objective of Master thesis research was to investigate the intensity of sugar beet diseases, determine the fungal disease prevalence and harmfulness of sugar beets, and determine the effect of chemical plant control against sugar beet diseases.The research was made in the Rumokai Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry in 2012. The soil type – Haplic-Epihypogleyic Luvisol – Idg8-p. Object of the research – sugar beet (Beta vulgaris saccharifera) fungal leaf diseases. Working methods: biological effectiveness of fungicides and disease harmfulness measurements were determined while using direct measurements, calculations or weighing according field experimental techniques (Šurkus, Gaurilčikienė, 2002). Research data have been statistically evaluated with a single factor or two factor analysis of variance of quantitative methods of evidence, using a computer program ANOVA (Tarakanovas, Raudonius, 2003). Research results: The most effective fungicide against Cercospora leaf spot disease in the once and twice treatment field of sugar beet plants was Maredo (once treatment rate 1,0 l ha-1, twice treatment rate 0,75 l ha-1). Its efficiency was highest and reached 65,79 – 92,06 % and 86,39 – 94,19 %. The most effective fungicideagainst Ramularia leaf spot disease in the once and twice treatment field of sugar beet plants was also Maredo. Its efficiency reached 75,41 – 93,52 % and 82,76 – 93,89 %. The highest significant root... [to full text]
