What is the most effective soil pH to inhibit the germination of Clubroot spores?

Maintaining a high soil pH, specifically at 7.2 or higher, is effective in inhibiting the germination of Clubroot spores, which are caused by the pathogen Plasmodiophora brassicae, a serious disease affecting cruciferous crops. High soil pH creates an unfavorable environment for the pathogen, as Clubroot prefers more acidic conditions typically found in soils with pH levels below 6.0. By increasing the soil pH to 7.2 or above, the likelihood of spore activation and subsequent infection reduces significantly, as this disrupts the pathogen's lifecycle and its ability to thrive in the soil. This practice is often employed in integrated pest management strategies to control Clubroot and protect sensitive crops.
