Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
143 words
A method of protecting plants from fungal diseases comprising contacting the fungus with a fungicidally effective amount of a compound of the formula: ##SPC13## wherein R is selected from the group consisting of hydrogen, alkyl containing from 1 to 10 carbon atoms, benzoyl and trichloromethylsulfenyl; R' is selected from the group consisting of hydrogen, alkyl containing 1 to 10 carbon atoms, alkenyl containing 2 or 3 carbon atoms, cyclohexyl, naphthyl, benzyl, pyridyl, thiazolyl, ethylene bis-, N-furylmethyl, phenyl, biphenylyl, and substituted phenyl wherein the substituents are selected from the group consisting of methyl, methoxy, nitro, halo, and carboxy, and X, Y and Z are independently selected from the group consisting of hydrogen, alkyl containing 1 to 17 carbon atoms, allyl, phenyl, and substituted phenyl wherein the substituents are selected from the group consisting of halo and nitro, or Y and Z together are 1,4-butylene.
Claim 2
Independent Claim
