“…Additionally, in 14.3% of the areas, the kale crop was preceded by kale itself or by broccoli, both of which are hosts to P. brassicae (Figure 2a). The successive cultivation of host species increases the inoculum potential and the occurrence of clubroot (HASSE et al, 2007;DIXON, 2009).…”

“…Although, the first report of clubroot in Brazil occurred in the kale crop in 1934, in São paulo (VIÉGAS & TEIXEIRA, 1943), there is still little research on the disease in the country (HASSE et al, 2007;RUARO et al, 2010;KOWATA-DRESCH & MAY-DE MIO, 2012;BHERING et al, 2017;SANTOS et al, 2017;BHERING et al, 2020;, especially in kale. Most of the information about the disease and proposed management strategies are based on studies carried out in temperate regions, mainly in the canola, Chinese cabbage, cauliflower and broccoli crops (WEBSTER & DIXON, 1991;NIWA et al, 2008;DIXON, 2009;GOSSEN et al, 2014).…”

“…In tropical and mountainous regions, the losses caused by clubroot can be aggravated by unique soil-climatic characteristics, such as high slope; weathered, naturally acidic soils or soils with high levels of Al 3+ ; high temperatures and precipitation; besides the possibility of growing Brassica all year round (HASSE et al, 2007;RUARO et al, 2010;BHERING et al, 2017;SANTOS et al, 2017;BOTERO et al, 2019;.…”

Clubroot disease, caused by Plasmodiophora brassicae, limits the production of Brassica spp. worldwide. Little is known about the factors related to the development of the disease in kale (Brassica oleracea var. acephala) plants and in crops in mountainous areas under tropical conditions. This study examined the severity of clubroot in kale crops as well as identify potential flaws in management and the soil and relief factors related to its occurrence. The study was conducted in 24 kale fields in the mountainous region of Rio de Janeiro (Brazil). Soil and kale growth management practices adopted in the region were identified and samples of soil and plants were collected. Subsequently, soil and relief attributes, disease severity, biomass and nutrient and Al contents and accumulation in the plants were determined. There was a high spread of the pathogen in the areas. Inappropriate and recurrent practices in the region were detected, e.g., sequential cultivation of host species, low adoption of soil fertility analysis and liming and conservation practices, and community use of agricultural machinery and implements without prior cleaning. The disease was associated with more acidic soils, subject to greater water accumulation and with high levels of Al3+ as well as with higher Al contents and accumulation in the roots. Management practices must be adopted in the region to reduce the potential inoculum of P. brassicae and to increase soil fertility.

“…A hérnia das crucíferas é uma doença de difícil controle devido suas características de desenvolvimento e a produção de estruturas de resistência, as quais sobrevivem por períodos de oito a dez anos no solo (Schuta, 2003;Friberg et al, 2005;Hasse et al, 2007). Este fato já inviabilizou o cultivo de brássicas em diversas propriedades, especialmente de municípios da Região Metropolitana de Curitiba (RMC).…”

O presente trabalho teve por objetivo avaliar a propensão à incidência e severidade da doença radicular hérnia das crucíferas nos municípios da Região Metropolitana de Curitiba (26 municípios), a partir de valores de pH do solo. As 14.452 análises de pH em CaCl2 foram realizadas entre os anos de 1999 e 2007, sendo os valores provenientes do Laboratório de Química e Fertilidade do Solo (DSEA/SCA/UFPR). Para verificar a propensão da incidência e severidade da doença, medidas de tendência do pH em CaCl2 foram confrontadas com faixas de pH pré-estabelecidas pela literatura. Com exceção de Adrianópolis (59,4%) e Doutor Ulysses (33,3%), os demais municípios estudados apresentaram alta propensão à doença no grau mais elevado de severidade (pH < 5,7), com valores de probabilidade maiores que 75%. Os resultados enfatizaram a necessidade de calagem e outras práticas de controle no manejo da hérnia das crucíferas

The antracnoses is a disease caused by the fungus Colletotrichum gloeosporioides f. sp. cepae, one of the major diseases in the culture of onion (Allium cepa L). The main control strategy of this fungus is the chemical fungicide control with this technique used in most crops. It is currently being studied disease control methods that are less harmful to the environment, showing up as a good alternative, the use of essential oils. Given the above, the objectives of this study were to evaluate the direct effect of essential oils of basil, lemongrass, sage, thyme and citronella as an alternative in the fungus control C. gloeosporioides and determine its effect on the physiological quality of onion seeds; evaluate the effect of these on conidial germination and mycelial growth of C. gloeosporioides; determine the effectiveness of essential oils in soil infested by the pathogen; determine, through the use of water restriction, the best osmotic potential for inoculation of onion seeds with the pathogen; and finally the effect of these essential oils in onion seed inoculated with C. gloeosporioides. The essential oils of lemongrass and sage not afeitaram the physiological quality of onion seeds, all essential oils promoted inhibition of germination of C. gloeosporioides spores. The essential oils of thyme, lemongrass and citronella, at a concentration of 2,000 ppm, completely inhibited the mycelial growth of the fungus. The essential lemongrass oil and fungicide treatments were more protected seeds of the pathogen reflected in its emergence in soil infested with the pathogen. For seed inoculation with the pathogen, the osmotic potential of -1.0 MPa did not affect seed germination, and contamination with the pathogen greater than the witness. Finally, treatment with the essential oil of lemongrass to 1,000 ppm, generated greater protection in the seeds against the fungus.
