Embodiment 1

[0035] Handling of bananas

[0036] Four organic, unripe (green) bananas were used per treatment. The skin of each banana was wounded three times using a cork borer according to the method described by de Lapeyre de Bellaire and Dubois (1987). Subsequently, use 15 μl containing 1 x 10 5 Each wound was inoculated with a suspension of Fusarium proliferatum at 4 spores / ml. After 4 hours of incubation at 20°C, each banana wound was treated with 100 μl of a freshly prepared aqueous antifungal composition containing natamycin (DSM Food Specialties, Delft, The Netherlands), dasenium, or both. In addition, the dithiocarbamate antifungals thiram, thiram oxide, thialine, thiramic copper chloride, disulfiram, ferbam, and maneb were tested alone or in combination with natamycin Zinc, maneb, Weibaimu, thiram, thiram, thiram, thiram, thiram, thiram, thiram, and thiram. The antifungal composition comprises 1.00% (w / w) methyl hydroxyethyl cellulose (MHEC), 0.40% (w / w) xanthan gum, 0.20% (...

Embodiment 2

[0043] Processing of strawberries

[0044] Twelve fresh, organic strawberries were used per treatment. Wound each strawberry with a 0.5 mm long incision containing 1 × 10 5 Each wound was inoculated with a suspension of Botrytis cinerea at 4 spores / ml. After incubation for 2 hours at 20°C, each strawberry was individually dipped for 1 minute in a freshly prepared aqueous antifungal composition comprising natamycin (DSM Food Specialties, Delft, The Netherlands), dasenium, or both. In addition, the dithiocarbamate antifungals thiram, thiram oxide, thialine, thiramic copper chloride, disulfiram, ferbam, and maneb were tested alone or in combination with natamycin Zinc, maneb, Weibaimu, thiram, thiram, thiram, thiram, thiram, thiram, thiram, and thiram. The antifungal composition also comprises 1.00% (w / w) methyl hydroxyethyl cellulose (MHEC), 0.40% (w / w) xanthan gum, 0.20% (w / w) antifoaming agent, 0.30% (w / w) citric acid, 0.39% (w / w) lactic acid and 0.11% (w / w) potassium sorb...

Embodiment 3

[0049] Handling of mandarins

[0050] Ten fresh, organic tangerines were used per treatment. The peel of each tangerine was wounded once using a cork borer according to the method described by de Lapeyre de Bellaire and Dubois (1987). Subsequently, use 10 μl containing 1 x 10 4 Each wound was inoculated with a Penicillium italicum suspension of 2 spores / ml. After incubation for 2 hours at 20°C, tangerines were each dipped for 1 minute in a freshly prepared aqueous antifungal composition containing natamycin (DSM Food Specialties, Delft, The Netherlands), dysonium, or both. In addition, the dithiocarbamate antifungals thiram, thiram oxide, thialine, thiramic copper chloride, disulfiram, ferbam, and maneb were tested alone or in combination with natamycin Zinc, maneb, Weibaimu, thiram, thiram, thiram, thiram, thiram, thiram, thiram, and thiram. In addition, the antifungal composition comprises 3.1% (w / w) beeswax, 0.76% (w / w) glycerin, 0.66% (w / w) polyoxyethylene sorbitan mon...

Abstract

The present invention relates to antifungal compositions and their use in the treatment of agricultural products.

Description

technical field [0001] The present invention discloses new antimicrobial compositions for controlling plant diseases and preventing microbial spoilage of crops. Background technique [0002] It is estimated that approximately 25% of the world's crop production is lost due to microbial spoilage, of which fungal spoilage is by far the most important cause. Prevention of food spoilage is very important from an economic point of view as well as a humanitarian point of view. After all, people in many parts of the world are suffering from hunger. [0003] Success in combating plant and crop diseases and mitigating their damage to yield and quality depends largely on the timely application of antifungal agents. Prolonged and frequent use of many antifungal agents, such as benzimidazoles, contributes to a reduction in their effectiveness due to the development of resistance phenomena. [0004] Dithiocarbamate-type compounds were originally used as accelerators in the rubber vulca...
