Embodiment 1

[0020] Formulation example 1: 50% fluthiacet-oxaclo-methyl wettable powder

[0021]

[0022] After the above-mentioned components are uniformly mixed according to the formula ratio, the 50% fluthiacet-oxaclofen wettable powder is obtained through jet milling.

Embodiment 2

[0023] Formulation example 2: 70% fluthiacet-oxafetil-oxaclo-methyl wettable powder

[0024]

[0025]

[0026] After the above-mentioned components are uniformly mixed according to the formula ratio, the 70% fluthiacet-oxaclofen wettable powder is obtained through jet milling.

Embodiment 3

[0027] Formulation example 3: 40% fluthiacet-oxaclozo-methyl emulsifiable concentrate

[0028]

[0029] First use part of acetone to completely dissolve fluthiazate and fenthiazate, then add emulsifier and other additives in sequence, and finally make up to 100% with acetone, and mix them into a uniform oil phase to obtain the 40% fluthiazol Esters · oxaclo-ester emulsifiable oil.

Abstract

The invention relates to the technical field of pesticides and discloses a soybean field herbicide composition. The composition comprises two active components, namely fluthiacet-ethyl and propaquizafop, wherein the weight ratio of the two active components is 1:192 to 4:3; the two active components account for 5-75 mass percent of the herbicide composition. According to the herbicide composition and a preparation thereof, the fluthiacet-ethyl and the propaquizafop serve as the active components which have complementary advantages; generation of the pesticide resistance of weed is retarded, the environment pollution is alleviated, the pesticide effect is improved, gramineae and broad-leaved weed in a soybean field can be simultaneously prevented by spraying the pesticides at a time, the using quantity and the using frequency of the pesticides are reduced, and the composition has a great application prospect.

Description

【Technical field】 [0001] The invention relates to a herbicide composition for preventing and controlling weeds in soybean fields, in particular to a herbicide for preventing and controlling grasses and broad-leaved weeds in soybean fields, which uses fluthiacet-ethyl and oxaclofen-methyl as active compounds Components of a binary herbicide composition. 【Background technique】 [0002] Soybean is an important food crop and oil crop in my country, and it is also an important export agricultural product in China, with an annual planting area of ​​nearly 10 million hectares. The canopy coverage of leguminous crops in the early growth stage is small, and it is easy to breed a variety of monocotyledonous and dicotyledonous weeds. The use of a single herbicide is often not effective in weeding. At present, there are many problems with the existing herbicides in soybean fields: one is that the widespread use of long-residual herbicides in some areas causes residual phytotoxicity of ...
