Fall application of Zero Grind limestone performed similar to spring applied hydrated lime. Generally, both products applied at 10 t/ha increased soil pH, reduced disease severity, increased yield and reduced spore density of P. brassicae in the soil. Clubroot, caused by Plasmodiophora brassicae Wor., is well...
The application of hydrated lime to bring an acidic soil up to pH 7.2, and/or weed control of cruciferous weeds did not affect clubroot severity on a clubroot resistant variety. The yield of a susceptible canola variety almost doubled with the application of hydrated lime,...
Research trials found that hydrated lime may be an effective tool for managing clubroot disease in canola when optimal timing and rainfall are achieved. Field and greenhouse trials found hydrated lime more effective than limestone applications, but is much more costly. Clubroot disease, caused by Plasmodiophora...
