Embodiment 1

[0041] Active ingredient (I) and active ingredient (II), the total amount of which accounts for the weight content of the ultra-low volume liquid is 30.2% oxamethyzine-tebuconazole ultra-low volume liquid (1:150)

[0042]

[0043] Under normal temperature and pressure, after weighing the proportioning raw materials required by the formula, first put part of the solvent into the reaction kettle, turn on the agitator of the reaction kettle, and put in the original drug of pyrazastrobin and triazole fungicides under stirring conditions, and wait for After complete dissolution (about 15 minutes), add the remaining solvent, co-solvent, and surfactant, and continue stirring for 15-60 minutes after adding the materials to obtain a uniform and transparent oily product.

[0044] Following the same steps as in Example 1, the following examples can be prepared.

Embodiment 2

[0046] Active ingredient (I) and active ingredient (II), the total weight content of the ultra-low volume liquid is 18.6% oxamethyzine-tebuconazole ultra-low volume liquid (1:30)

[0047]

Embodiment 3

[0049] Active ingredient (I) and active ingredient (II), the total amount of which accounts for 60% of the weight content of the ultra-low volume liquid preparation is oxamethoxam·tebuconazole ultra-low volume liquid preparation (1:1)

Abstract

The invention discloses an ultra-low volume liquid containing ametoctradin and triazole bactericide composition as well as a preparation method and an application thereof. In the liquid, the weight percentage content of an active constituent (I) is 0.1-30%, the weight percentage content of an active constituent (II) is 0.1-30%, the balance is a surfactant, a solvent and a cosolvent, and the active constituent (II) is one of tebuconazole, difenoconazole, propiconazole, epoxiconazole, hexaconazole and fusilazole. The preparation method comprises the steps: stirring the active constituents (I) and (II) by using partial solvent in a mixing kettle with a stirring device at first for dissolution, then, adding the surfactant, the cosolvent and the residual solvent, and fully stirring for mixing uniformly to obtain the ultra-low volume liquid. Specific to the defects of low working efficiency, large labor intensity, high water consumption and poor safety regarding to the traditional agricultural control and the problems of single control effect, obvious resistance, short lasting period and the like of a chemical, the invention provides the ultra-low volume liquid containing the ametoctradin and triazole bactericide composition.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an ultra-low-capacity liquid formulation containing a combination of pyraclostrobin and triazole fungicides. The ultra-low-capacity liquid formulation is suitable for ultra-low-volume spraying, low-volume spraying and electrostatic spraying pesticide. Background technique [0002] With the realization of my country's land transfer contract system, the agricultural production method has entered the threshold of modern facility agriculture and large-scale agriculture from the traditional cultivation method. The method puts forward higher requirements. At present, domestic pesticide control operations have low efficiency and high labor intensity, and it is difficult to meet the requirements of farms and large-scale planting areas for pest control. Secondly, pesticide preparations need a large amount of water, which is not suitable for the prevention and control of fa...
