Abstract
The present invention refers to biocidal mixtures with disinfecting and microbicidal activity which also enhance root growth, containing as active ingredients poly[beta(1,4)-2-amino-2-deoxyglucopyranose] oligomers as per formula I, and oxidized natural lignin phenols with a low molecular weight. It also refers to agronomically efficient compositions against fungi, bacteria, insects and nematodes which are harmful to plants in agricultural crops, as well as their uses in agriculture.
Claims6
A biocidal aqueous composition comprising a synergistic combination of:
- (1) an effective amount of a poly[beta(1,4)-2-amino-2-deoxyglucopyranose] oligomers as per formula I,
- (2) an effective amount of an oxidized natural lignin phenols;
- (3) a weak acid;
- and
- (4) water, wherein the component (1) has a molecular weight equal to or less than 10,000 g/mol and it is between 1% and 10% (by volume), the component (2) has a molecular weight equal to or less than 800 g/mol and is present in the composition at between 2% and 10% (by volume).
