Embodiment 1

[0046] Active ingredient (I) and active ingredient (II), the total amount of which accounts for 40.1% of the weight of the ultra-low-volume liquid formulation, and the oxalazine-chlorothalonil ultra-low-volume liquid formulation

[0047]

[0048] At normal temperature and pressure, put octazole, chlorothalonil and part of the solvent into the reaction vessel with stirring, and at a stirring speed of 60-150 rpm, the solvent stirs octazole and chlorothalonil Dissolve, then add additives and remaining solvents, fully stir for 15 to 60 minutes to make it evenly mixed, and then obtain 40.1% oxamethoxam·chlorothalonil ultra-low volume liquid.

[0049] Following the same steps as in Example 1, the following examples can be prepared.

Embodiment 2

[0051] Active ingredient (I) and active ingredient (II), the total amount of which accounts for the weight content of the ultra-low volume liquid formulation is 28% of the oxalazine·chlorothalonil ultra-low volume liquid formulation

[0052]

Embodiment 3

[0054] Active ingredient (I) and active ingredient (II), the total amount of which accounts for 30.0% of the weight content of the ultra-low volume liquid formulation, and the oxalanthal-chlorothalonil ultra-low volume liquid formulation

Abstract

The invention discloses an ultralow-volume liquid of ametoctradin and phenyl and o-phthalimide-containing fungicide composition, belonging to the field of pesticides. The ultralow-volume liquid comprises the following compositions by weight percent: 0.1%-30% of an active ingredient (I), namely ametoctradin, 1%-40% of an active ingredient (II), and the balance being a solvent and auxiliaries, wherein the active ingredient (II) is one of chlorothalonil, captan and folpet, and the auxiliaries are one or more of surfactant, a synergist, and a penetrant. The invention provides the ultralow-volume liquid of ametoctradin and phenyl and o-phthalimide-containing fungicide composition, and provides a preparation method for the ultralow-volume liquid.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to pesticides suitable for ultra-low volume spraying, low volume spraying and electrostatic spraying. Background technique [0002] As agricultural production methods move from traditional cultivation methods to the threshold of modern facility agriculture and large-scale agriculture, large-scale planting such as farms will replace traditional planting methods, and the prevention and control of explosive pests and diseases is due to low work efficiency, high labor intensity, and high control efficiency. Low and poor security seriously restrict the development of my country's modern facility agriculture. Secondly, pesticide preparations need a large amount of water, which is not suitable for the prevention and control of far away from water sources, drought and water shortage, and large-scale crop diseases and insect pests. With the single and frequent use of high-efficiency pesticide varie...
