Abstract. Apple fruit rot can be caused by several fungi. In Northern Europe, the most common storage rot, Bull's eye rot, is caused by Neofabraea spp., bitter rot by Colletotrichum spp., brown rot by Monilinia fructigena, grey mould is caused by Botrytis cinerea and Fusarium rot by several Fusarium species. Blue mold decay caused by Penicillium expansum is an important disease in several European countries. Incidence of different causal agents may vary depending on cultivar, climate during growing season and agricultural practices. The main objective of the study was to obtain baseline information about apple rot-causing fungi, their incidence during fruit storage and to evaluate the fungicide sensitivity of most of isolated fungal species. The study was performed during the storage period of apples after the growth season of 2013. Rotten apples were sorted in the storage and part of them was brought to the laboratory in order to obtain fungal isolates. Fungi were identified according to the morphological characteristics and sequencing of the ITS1-5.8S-ITS2 region. During storage in February and March the total percentage of rotten apples in various cultivars varied from 3.6 to 58.9%. All post-harvest diseases described in Northern Europe were detected. In part of the storehouses apple rot caused by Cadophora luteo-olivacea was observed. Alternaria spp. and Cladosporium spp. were detected on few apples as secondary infection agents. Using the most often isolated fungal species, sensitivity tests were performed against five commonly used fungicides. In general, the sensitivity of tested fungi to the fungicides was high with exception of several Neofabraea and Alternaria isolates.

“…Mesmo dentro do grupo das estrobilurinas, o efeito sobre a germinação de conídios e crescimento micelial variou conforme já relatado para Alternaria alternata (Fr.) �eissl., para a qual a germinação de conídios foi pouco sensível a azoxystrobin, mas altamente sensível a trifloxystrobin (Reuveni & Sheglov, 2002).…”

“…Alta sensibilidade quanto ao crescimento micelial e baixa sensibilidade quanto à germinação de conídios já foram observadas em trabalhos com os IBE (Gisi et al, 2000;Reuveni & Sheglov, 2002). Por exemplo, tebuconazole inibiu a germinação de conídios de vários isolados de Botrytis cinerea a 3 ou 5µg i. a./mL (Elad, 1992).…”

Eficiência de fungicidas sistêmicos para o controle de Cylindrocladium candelabrum em eucalipto

et al. 2006

Várias espécies de Cylindrocladium podem causar doenças em mudas de eucalipto, na propagação clonal. Apesar de, em algumas situações, fungicidas serem imprescindíveis no controle desses patógenos, faltam estudos para avaliar a efetividade desses produtos. Por isso, objetivou-se selecionar fungicidas sistêmicos para controlar C. candelabrum, determinar o efeito protetor, curativo e anti-esporulante dos fungicidas, sua translocação e persistência em plantas de eucalipto. Nos experimentos in vitro foram testados: azoxystrobin (AZO), triadimenol (TRI), boscalid (BOS), pyraclostrobin (PYR), carbendazim (CAR), tetraconazole (TET), tebuconazole (TEB), epoxiconazole+pyraclostrobin (EPO-PYR) e epoxiconazole (EPO) nas concentrações 0,1, 1, 5, 10, 50, 100 e 1000 µg de i.a/mL. Nos experimentos in vivo, utilizou-se um clone suscetível a C. candelabrum (Eucalyptus grandis x E. urophylla). Excetuando-se o estudo da atividade translaminar, aplicaram-se os fungicidas, em ambas as faces do limbo foliar. Após 24 h, as plantas foram inoculadas com suspensão de 10(5) conídios/mL de C. candelabrum. Testou-se o efeito protetor dos fungicidas, em diferentes concentrações: AZO (0,2; 0,25; 0,4; 0,65 e 0,8 g/L), EPO (0,75; 1,125; 1,5; 1,875 e 2,25 mL/L), EPO-PYR (1,25; 1,875; 2,5; 3,125 e 3,75 mL/L), PYR (0,75; 1,125; 1,5; 1,875 e 2,25 mL/L) e TEB (0,75; 1,125; 1,5; 1,875 e 2,25 mL/L), selecionados nos testes in vitro. Para avaliar o efeito curativo, anti-esporulante, a persistência e a atividade translaminar, utilizaram-se os fungicidas: AZO (0,4 g/L), EPO (1,5 mL/L), EPO-PYR (2,5 mL/L) e TEB (1,5 mL/L). Obteve-se efeito protetor, curativo e anti-esporulante com EPO, EPO-PYR e TEB, os quais tiveram atividade translaminar e persistência nos tecidos foliares.

“…As a systemic sterol demethylation inhibitor, difenoconazole is highly effective against the diseases caused by various fungi infecting cereals targeting ergosterol biosynthesis by inhibiting the fungal enzyme sterol-1-4-a-demethylase [7][8][9]. Given its capability to control various fungal diseases, difenoconazole has been extensively used in a wide range of crops in many countries.…”

Among eight ionic liquids (ILs) examined, 1-n-butyl-4-methyl-pyridinium bromide (BMPyBr, 5) was used in this study as an appropriate alternative to benzene homologs and derivatives to be used in 10 wt% water-insoluble difenoconazole emulsifiable concentrate (EC). Moreover, 10 wt% difenoconazole EC with BMPyBr (5) exhibited the same efficacy as 10 wt% difenoconazole wettable powder (WP) against powdery mildew on cucumbers under field conditions. The results revealed that difenoconazole EC with BMPyBr (5) had excellent stability at 268 K and 327 K after 14 days through high-performance liquid chromatography (HPLC). Therefore, ILs can be considered as promising environment-friendly adjuvants for pesticides that are commercially processed as EC formulation.
