Abstract
Clubroot is a damaging disease of oilseed rape and vegetable brassicas worldwide, caused by the soil-borne protist Plasmodiophora brassicae Wor. Due to the long life of resting spores, the assessment of the pathogen abundance in agricultural fields can serve as a guideline for disease control at the country-wide level or the regional scale. Between 2013 and 2019, we collected 431 soil samples from fields cultivated with Brassicaceae crops throughout 16 provinces of Poland. The samples were subjected to qPCR based analysis of P. brassicae DNA concentration. From these data, the spore loads and gene copies g−1 soil were calculated and used to produce an assessment of the current clubroot risk potential at a country-wide and regional scale. The country-wide map, showing the spread of the pathogen in agricultural soils, was made using ArcGis software package implementing the interpolation with the Inverse Distance Weight method. The calculation of gene copies specific to P. brassicae helped to formulate the recommendations for farmers in respect to the cultivation guidelines. It showed a high risk of yield losses in defined regions of north, south-west and central Poland and an urgent need to undertake intensive preventative measures.
Highlights
The genus Brassica, especially cabbage and oilseed rape, represents a significant segment of agricultural production in many countries, including Poland
Spores extracted from Chinese cabbage roots infected with five isolates of P. brassicae obtained under the microscope and a real-time qPCR
Our study clearly shows that in Poland, intensive preventive actions should be undertaken to reduce the further spread of P. brassicae, as over one-fifth of the fields was highly infested by P. brassicae
Summary
The genus Brassica, especially cabbage and oilseed rape, represents a significant segment of agricultural production in many countries, including Poland. Since 2005, this significant acreage has ranked Poland in 4th place in the European Union for the production of oilseed rape. Clubroot caused by a protist Plasmodiophora brassicae is a damaging soil-borne disease of Brassica crops, first described in 1878 by Woronin [1]. It is widespread throughout the world; it has been found in 35 European countries, 11 Asian countries, 10 countries in North and South America, three regions of Oceania, as well as in Africa [2]. Very high crop losses were reported in all countries growing vegetable brassicas and oilseed rape, primarily in Canada [3] and European Union [2]. Clubroot is considered one of the most economically important threats to Brassicaceae production [7,8]
