Embodiment 1

[0049] Example 1 Determination of synergistic effect of prochloraz (A) and active ingredient B in vitro

[0050] The active ingredients B are 2-nonanone (B1), 2-methylpyrazine (B2) and 2-decanone (B3).

[0051] The experimental object was mango anthracnose.

[0052] The experimental drug is the original drug or the original solution. Weigh a certain amount of the original drug of prochloraz and the active ingredient B, respectively, add a certain amount of methanol to completely dissolve or mix them, and then add 0.1% Tween-80. Bacteria water, prepared into mother liquor. On the basis of the mother liquor, according to the results of the pre-experiment, more than 5 dilutions with a series of formula concentrations were prepared, and 5 replicates were set for each concentration. And according to the preliminary experimental results, the proportions of Prochloraz:B were 10:0.5, 10:1, 10:2, 10:3, 10:4, 10:5, respectively, and the mixture containing 0.1% Tween-80 was used. Dilu...

Embodiment 2

[0070] Embodiment 2: the water emulsion 1 that prochloraz and 2-nonanone are compounded

[0071] The composition and proportions are:

[0072]

[0073] Processing method: Mix prochloraz and 2-nonanone with solvent to dissolve prochloraz completely, add surfactant and stir well to make oil phase; mix water, preservative and thickener evenly to make water The oil phase is added to the water phase and stirred well, and sheared with a high-speed shearing machine to obtain a stable and uniform water emulsion.

Embodiment 3

[0074] Embodiment 3: the water emulsion 2 compounded by prochloraz and 2-nonanone

[0075] The composition and proportions are:

[0076]

[0077] The processing method is the same as that of Example 2.

Abstract

The invention relates to a bactericide composition which is used for keeping fruits and vegetables fresh after harvest and used for preventing and treating microorganism diseases. The bactericide composition is prepared from prochloraz A and effective component B which have the synergistic effect. The effective component B is one or more of n-heptyl methyl ketone, 2-methyl pyrazine and methyl octyl ketone, the mass ratio of A to B is 10:(0.5-5), and the effective component A and B account for 10-52.5% of the mass of the composition. By means of the bactericide composition, the bactericide effect is remarkably improved, the consumption of chemical preservatives is lowered, the environment pollution and bactericide residual are reduced, and safety is higher.

Description

technical field [0001] The invention belongs to the field of preservation of fruits and vegetables, and particularly relates to a bactericide composition, which is used for preservation of fruits and vegetables. Background technique [0002] my country is a major producer of fruits and vegetables, with a total area of ​​483 million mu, an output of 792 million tons, and an output value of more than 1.5 trillion yuan, ranking first in the world. In my country, fruit rot accounts for more than 25% of the total output, and vegetable rot accounts for more than 30% of the total output. The two total about 80 million tons, causing economic losses of more than 100 billion yuan. Restricted by the level of economic development, cold chain and advanced logistics equipment and facilities are difficult to be widely used in my country, and the post-harvest losses of fruits and vegetables are serious. Fruit and vegetable preservatives have become an important means to reduce post-harvest ...
