Abstract

Control of Xanthomonas campestris pv. campestris in crucifer seed with slurry treatments of calcium hypochlorite.

Abstract

In 16 seed treatment (soaks or slurries) tests the pathogen was reduced to undetectable levels in 1 lab.-infested Brassica oleracea seed lot and in 8 of 15 naturally infected lots when seed was slurry-treated with calcium hypochlorite at 10-20 g a.i./kg seed and left sealed in containers for 16 h. Slurry treatments had no immediate effect on germination but reduced it in some lots after 6 months. Slurry treatment is more compatible than soaks with commercial seed-conditioning practices and has less potential for injury to seed or spread of nontarget pathogens.
