Abstract
Abstract An antifungal preparation to be used in and on agricultural products such as fruit, vegetables, tubers, root-tubers, flower bulbs and rootstocks comprising an amount of polyene antibiotic, peferably natamycin, effective to prevent or inhibit mold growth on the agricultural products dissolved in a mixture of a lower alkanol, such as ethyl alcohol, and a lower alkanoic acid, such as acetic acid and agricultural products treated with this preparation and the method of treatment by submerging the agricultural products in the preparation or by pasting or spraying the preparation onto the agricultural products.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
77 words
An antifungel composition for use on agricultural products comprising 0.05 to about 0.5% by weight of a polyene antibiotic selected from the group consisting of natamycin, aureofungin, lucensomycin and the alkali metal salts, alkaline earth metal salts or lower alkyl esters thereof to prevent or inhibit mold growth on the agricultural products dissolved in a mixture of 10 to 99% by weight of a lower alkanol and 0.05 to 5% by weight of a lower alkanoic acid.
Claim 2
Dependent Claim
77 words
An antifungel composition for use on agricultural products comprising 0.05 to about 0.5% by weight of a polyene antibiotic selected from the group consisting of natamycin, aureofungin, lucensomycin and the alkali metal salts, alkaline earth metal salts or lower alkyl esters thereof to prevent or inhibit mold growth on the agricultural products dissolved in a mixture of 10 to 99% by weight of a lower alkanol and 0.05 to 5% by weight of a lower alkanoic acid.
