Embodiment 1

[0034] pre-harvest application

[0035] Inoculate the leaves of banana plants with the fungus. Uninoculated leaves were included as controls. Then, use composition 1 (natamycin), composition 2 (azoxystrobin), composition 3 (kresstrobin), composition 4 (phenoxystrobin), composition 5 (trifloxystrobin), Composition 6 (Picoxystrobin), Composition 7 (Pyraclostrobin), Composition 8 (Kysstrobin), Composition 9 (Fluooxastrobin), Composition 10 (Kysstrobin), Composition 11 (natamycin + azoxystrobin), composition 12 (natamycin + azoxystrobin), composition 13 (natamycin + fenoxystrobin), composition 14 (natamycin Composition 15 (natamycin + pyraclostrobin), composition 15 (natamycin + pyraclostrobin), composition 17 (natamycin + pyraclostrobin ), the composition 18 (natamycin + fluoxastrobin) or the composition 19 (natamycin + orysastrobin) to treat a defined part of the leaves. Each composition is applied by spraying. Untreated leaves were also included (untreated control).

Embodiment 2

[0038] post harvest application

[0039] Bananas were wounded according to the method described by de Lapeyre de Bellaire and Dubois (1987). Bananas were wounded using a cork puncher, after which they were contaminated with fungal spores. After several hours of incubation at room temperature, the bananas were immersed in one of the following compositions: a) no treatment (control 1), b) in water (control 2), c) in natamycin, d) Soaked in Azoxystrobin, e) Soaked in Kresstrobin, f) Soaked in Phenoxystrobin, g) Soaked in Trifloxystrobin, h) Soaked in Picoxystrobin, i) Soaked in Pyrostrobin In pyraclostrobin, j) in kysoxstrobin, k) in fluoxastrobin, l) in oryzastrobin, m) in natamycin + azoxystrobin, n ) soaked in natamycin + kresoxim-methyl, o) soaked in natamycin + fenoxystrobin, p) soaked in natamycin + trifloxystrobin, q) soaked in natamycin + picoxystrobin, r) soaked in natamycin + pyraclostrobin, s) soaked in natamycin + kyrestrobin, t) soaked in natamycin + fluoxastrobin...

Embodiment 3

[0042] handling bananas

[0043] Four organic, unripe (green) bananas were used per treatment group. 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 spores / ml of Fusarium proliferatum suspension. After incubation at 20°C for 4 hours, each banana was treated with 100 μl of a freshly prepared aqueous antifungal composition containing 500 ppm natamycin (DSM Food Specialties, Delft, The Netherlands), 1000 ppm fluoxastrobin or both wound. In addition, the antifungal composition 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 sorbate. The pH of the composition is 4. A composition without natamycin and fluoxastrobin was used as a control. The treated, unripe bananas...

Abstract

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

Description

Technical field [0001] The present invention discloses novel antifungal compositions for controlling plant diseases and preventing microbial spoilage of crops. Background of the invention [0002] It is estimated that about 25% of the world's crop production is lost due to microbial spoilage, with spoilage caused by fungi being by far the most serious cause. Preventing food spoilage is very important from both an economic point of view and a humane point of view. After all, people in many parts of the world suffer from hunger. [0003] Success in combating plant and crop diseases and mitigating the damage they cause to yield and quality depends significantly on the timely application of fungicides. Long-term and frequent use of many fungicides (e.g. benzimidazole) contributes to a reduction in their effectiveness due to the development of resistance phenomena. [0004] An important class of fungicides are the strobilurins. They were originally sold in 1996. Sales of met...
