Abstract
Abstract Certain 4-chromones, 4-chromanones, 4-chromone oximes, and 4-chromanone oximes have been found to be active against fungi. These generally well-known compounds can be applied to seeds, plants, animals, objects, or places for preventing damage due to fungi. Specific, recognized active compounds, e.g., 6,8-dichloro-3-methyl-4-chromone oximes and 3-methyl-4-chromanone oximes are shown to be so useful in detail. General methods of preparing the active compounds are described.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A method for controlling fungi comprising the appliction of an effective antifungal amount of a compound of the formula: ##STR4## wherein X is chlorine, bromine, lower alkyl of 1 to 4 carbon atoms, trifluoromethyl, methoxy, ethoxy, methylthio, or ethylthio; n is an integer 0, 1, 2, or 3; Z is the oxygen atom or the oximino group (═NOH); R 3 is hydrogen, halogen, hydroxyl, or lower alkyl; and R 1 and R 2 are halogen, lower alkyl, or hydrogen provided that X and n are selected independently and that 6-X is 6-chloro or 6-bromo when R 3 is hydroxyl, applied to fungi.
Claim 2
Independent Claim
102 words
A method for controlling fungi comprising the appliction of an effective antifungal amount of a compound of the formula: ##STR4## wherein X is chlorine, bromine, lower alkyl of 1 to 4 carbon atoms, trifluoromethyl, methoxy, ethoxy, methylthio, or ethylthio; n is an integer 0, 1, 2, or 3; Z is the oxygen atom or the oximino group (═NOH); R 3 is hydrogen, halogen, hydroxyl, or lower alkyl; and R 1 and R 2 are halogen, lower alkyl, or hydrogen provided that X and n are selected independently and that 6-X is 6-chloro or 6-bromo when R 3 is hydroxyl, applied to fungi.
Claim 3
Dependent Claim
23 words
The method according to claim 1 wherein Z is the oximino group and X is located at the 5, 6 or 8 positions.
