Conteúdo: | Surface application of urea to soil at a rate of 25 kg/ha to 150 kg/ha was effective in controlling carpogenic germination of sclerotia of Sclerotinia sclerotiorum. Surface application of urea to sterile soil was ineffective in preventing carpogenic germination of sclerotia unless the soil was also treated with urease. Ammonia released from the decomposition of urea appeared to be the key toxic agent responsible for the inhibition of carpogenic germination of sclerotia of S> sclerotiorum.
