seeds which germinate quickly than in the case of seeds whose 
germination is normally slow. After treated seeds have germinated 
growth is rapid, and in a short time the plants are equal in size an 
vigour to the plants from untreated seeds sown at the same time. 
n some cases the plants from treated seeds are a eek 
than those from untreated seeds at the end of three weeks. 
all practical purposes, soaking seed in weil sies Seite for three 
hours will kill all superficial fungus spores and the seed will not be 
injured, This method is to be recommended as a substitute for 
fumigation, which, as a rule, does not kill fungus spores, unless 
continued for such a time as to damage the seed.
