Abstract
Triazoles of formula: ##STR1## wherein R.sub.1 is alkenyl, alkynyl or optionally substituted aralkyl; Y is .dbd.N--, R.sub.2 is cycloalkyl, alkyl or haloalkyl, and R.sub.3 is H, methyl or alkenyl, or esters, ethers, salts and metal complexes thereof. The triazoles have fungicidal and plant growth regulating activity.
Claims55
A compound having plant fungicidal and/or plant growth regulating activity and the formula ##STR8## wherein Y is .dbd.N--, R.sub.1 is allyl or is benzyl optionally ring substituted with one or two substituents selected from the class consisting of halogen, C.sub.1-4 alkyl, halo (C.sub.1-4 alkyl), C.sub.3-6 cycloalkyl, nitro, cyano, C.sub.1-4 alkoxy and (C.sub.1-4 alkylene)dioxy, and/or optionally substituted on the .alpha.-carbon atom with one C.sub.1-4 alkyl, R.sub.2 is propyl or butyl and R.sub.3 is hydrogen or methyl;
- or an alkanoate ester, an acid addition salt or a copper, zinc, manganese or iron complex thereof.
A compound having the formula ##STR9## wherein Y is --N--, R.sub.1 is allyl or is benzyl optionally ring substituted with one or two substituents selected from the class consisting of halogen, methyl, ethyl, trifluoromethyl, nitro, cyano, methoxy and ethoxy, and/or optionally substituted on the .alpha.-carbon atom with one methyl, R.sub.2 is i-propyl, i-butyl or t-butyl and R.sub.3 is hydrogen or methyl;
- or an acetate ester, an acid addition salt or a copper, zinc, manganese or iron complex thereof.
A method of stunting the growth of a grass, the method consisting essentially of applying to the grass, to seed of the grass or to the locus of the grass or seed, and in an amount sufficient to stunt the growth of the grass, a compound of formula:
- ##STR10## wherein Y is .dbd.N--, R.sub.1 is benzyl optionally substituted with one or two substituents selected from the class consisting of halogen, C.sub.1-4 alkyl and nitro, R.sub.2 is butyl and R.sub.3 hydrogen;
- or an alkanoate ester, an acid addition salt or a copper, zinc, manganese or iron complex thereof.
