Abstract

Control of fungi by using a composition comprising a compound of the formula WHEREIN X1, X2 and X3 are hydrogen, halogen of atomic number 9 to 35 (fluorine, chlorine or bromine) or hydrocarbon carboxyacyl of one to five carbon atoms and R is hydrogen, aliphatic hydrocarbon group of one to five carbon atoms or aliphatic hydrocarbon group of 1 to 6 carbon atoms substituted one to four hydroxy groups or halogens of atomic number 17 to 35.

Claims

2. The method of claim 1 wherein X1, X2 and X3 are hydrogen, halogen of atomic number 17 to 35 or alkanoyl of one to five carbon atoms.

3. The method of claim 1 wherein X1, X2 and X3 are hydrogen, chlorine, bromine or acetyl and R is hydrogen, alkyl of one to two carbon atoms substituted with 0 to 2 hydroxy groups or halogen atoms of atomic number 17 to 35, or alkynyl of two to three carbon atoms.

4. The method of claim 1 wherein X1 and X2 are the same and X3 is hydrogen.

5. The method of claim 1 wherein X1, X2 and X3 are the same.

6. A method for controlling fungi which comprises contacting said fungi or vegetative hosts which are subject to fungus attack with a fungicidal amount of a compound of the formula wherein X1 and X2 are the same and are bromine, chlorine or alkanoyl of one to five carbon atoms, X3 is hydrogen, and R is hydrogen, alkyl of one to four carbon atoms, alkynyl of two to four carbon atoms, alkyl of one to four carbon atoms substituted with one to four hydroxy groups or halogen of atomic number 17 to 35.
