Abstract
2-Alkoxyimino-N-carbamoyl-2-cyanoacetamides are unstable in the presence of bases, even bases which are quite weak. Fungicidal compositions of these compounds are stabilized by the addition of an acidulant.
Claims3
A fungicidal composition consisting essentially of
- (a) 10 parts of a compound of the formula ##STR2## wherein R is methyl or ethyl, and
- R.sub.1 is hydrogen, alkyl of 1-4 carbon atoms or allyl;
- (b) a fungicidally effective amount of zineb;
- and
- (c) from 1 to 100 parts of an acidulent having a pH of 2 to 5.7 in a 1% distilled water mixture and a free acidity of from 2.5 millimoles per gram to 22 millimoles per gram of acidulent when titrated in a 1% distilled water mixture to a pH of 7.
