Embodiment 116

[0052] Formulation example 1 16% fludioxonil · chitosan oligosaccharide suspension

[0053] Components are composed as follows (each component is by weight percentage):

[0054]

[0055] Water topped up to 100%.

[0056] The preparation method is as follows: the above-mentioned active ingredients, various additives and water are fully mixed in proportion, put into a sand mill, and ground to a particle size of 5 μm to prepare a 16% fludioxonil·chitooligosaccharide suspension.

Embodiment 212

[0057] Formulation example 2 12% fludioxonil · chitosan oligosaccharide wettable powder

[0058] Components are composed as follows (each component is by weight percentage):

[0059]

[0060] Bentonite (filler) makes up to 100%.

[0061] The preparation method is as follows: the above-mentioned active components, various auxiliary agents and fillers are fully mixed in proportion, and the mixture is pulverized by an ultrafine pulverizer to obtain a 12% fludioxonil·chitooligosaccharide wettable powder.

Embodiment 320

[0062] Formulation example 3 20% fludioxonil·chitooligosaccharide emulsion in water

[0063] Components are composed as follows (each component is by weight percentage):

Abstract

The present invention discloses an application of a combination of fludioxonil and chitooligosaccharides in preventing and treating storage diseases of fruits and vegetables. The diseases are grape gray mould blight and young garlic shoot gray mould blight caused by botrytis cinerea. In the specific application, the fludioxonil and chitooligosaccharides are combined to be prepared into a sterilization composition, the sterilization composition is diluted with water, the diluted sterilization composition is sprayed on or dipped on surfaces of the fruits and vegetables, and after the fruits andvegetables are air-dried, the air-dried fruits and vegetables can be stored conventionally in cold storages; in the sterilization composition, a weight ratio of the fludioxonil to chitooligosaccharides is (1-3):(1-3) or 1:15, preferably 1:(2-3) and more preferably 1:2 and 1:3. The present invention also discloses a preservative and fresh-keeping agent. The preservative and fresh-keeping comprises0.5%-50% of fludioxonil, 0.5%-15% of chitooligosaccharides and the balance allowed and acceptable accessory materials in agricultural pharmacology. The combination of the fludioxonil and the chitooligosaccharide has the following advantages: (1) the combination of the fludioxonil and the chitooligosaccharide is obvious in synergistic interaction effects; (2) the combination of the fludioxonil andthe chitooligosaccharide reduces use amounts and use times of chemical sterilization agents; (3) a combined use of medicaments with different action mechanisms delays a generation of a drug resistanceof the sterilization agents; and (4) vegetable and fruit products are more significant in preservation and fresh-keeping.

Description

technical field [0001] The invention relates to the application of fludioxonil combined with chitosan oligosaccharide in preventing and curing diseases of fruits and vegetables during storage, and belongs to the field of prevention and treatment of post-harvest diseases of fruits and vegetables. Background technique [0002] With the development of science and technology, people's living standards are gradually improving, and the demand for fruits and vegetables produced in different seasons and regions is increasing. However, after fresh fruits and vegetables are harvested, they still undergo complex physiological, biological and physical changes. The cells and tissues of fruits and vegetables continue to respire and transpirate, which is prone to rot, wilting, deterioration and other phenomena, which affects the quality of fruits and vegetables. and sales. Therefore, preservation of fruits and vegetables is a very important issue in the production, storage and sales of fr...
