Clubroot is a devastating disease of brassica crops including broccoli, brussels sprouts, cabbage, and cauliflower. Infected roots are unable to absorb water and nutrients, top growth is stunted and lower leaves may yellow and drop off.
There is little effective genetic resistance to this disease and no chemical control measures. Using extended crop rotations has proven helpful. In addition, since low pH can provide beneficial conditions for germination of clubroot spores close to the roots, one very important management factor that the growers can use is nitrate nutrition. YaraLiva Calcium Nitrate does not induce a residual acid reaction in the rhizosphere and thus can help suppress clubroot development. Also, a good calcium nutrition reduces the incidence of clubroot by strengthening cell walls and increasing membrane integrity. Crops that are well supplied with calcium are more resistant to attack by pathogens and have a reduced risk of infection and gall formation.
YaraLiva Calcium Nitrate is available as either YaraLiva Tropicote, a dry granule that readily dissolves and quickly moves into the soil, YaraLiva Calcinit, a dry granule specially formulated to readily dissolve for use in fertigation, or liquid YaraLiva CN-9 and YaraLiva CAN-17.
