Embodiment 1

[0027] Example 1: 1% florasulam + 5% pinoxaden + 20% clodinafop emulsifiable concentrate

[0028] Flumesulam 1%; pinoxaden 5%; clodinafop-propargyl 20%; conventional emulsifier 10-30%; conventional solvent 20-50%; Sulcolam, pinoxaden and clodinafop-propargyl are added to the solvent to completely dissolve, then add emulsifier, synergist and stir evenly to form a uniform transparent oily liquid, fill it, and then the emulsifiable concentrate preparation of the composition of the present invention can be made .

Embodiment 2

[0029] Example 2: 5% florasulam + 7.5% pinoxaden + 15% clodinafop-propargyl wettable powder

[0030] Flumefecil 5%; pinoxaden 7.5%; clodinafop-propargyl 15%; sodium lauryl sulfate 10%; sodium lignosulfonate 5%; white carbon black 10%; The above components are mixed in proportion, ground and pulverized to prepare wettable powder.

Embodiment 3

[0031] Example 3: 10% florasulam + 50% pinoxaden + 10% clodinafop-propargyl aqueous emulsion

[0032] Flosulam 10%; pinoxaden 50%; clodinafop-propargyl 10%; N-methylpyrrolidone 25%; calcium dodecylbenzenesulfonate 5%; 100%, the above oil phase components are mixed and then added to the water phase to obtain a water emulsion.

Abstract

A synergistic weeding composition is provided. Effective components of the composition are florasulam, pinoxaden and clodinafop-propargyl. The mass ratio of the florasulam, the pinoxaden and the clodinafop-propargyl is 1-50:1-50:1-50. The total mass of the florasulam, the pinoxaden and the clodinafop-propargyl in a preparation is 1-80% of the mass of the preparation. The dosage form of the composition is an emulsifiable solution, a suspension, wettable powder, water-dispersible granules, an emulsion in water, a microemulsion, and a microcapsule. The weeding spectrum of the composition is wide. The composition can effectively control a plurality of broadleaf weeds and sedges in wheat fields.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a ternary compound herbicidal composition containing florasulam, pinoxaden and clodinafop-propargyl. Background technique [0002] The geographical distribution of wheat is very wide, and the hazards of weed species are also very complex. Weeds compete with wheat for water, nutrients, light and space, affecting the normal growth of wheat seedlings, and even causing serious production reduction. [0003] With the development of agricultural science and technology, the popularization and application of chemical herbicides has been taken as one of the powerful measures to increase production by saving labor, time and cost. However, the use of herbicides involves a balance between the effect on weeds and the safety of crops, which is highly demanding and cannot be used indiscriminately. On the basis of indoor screening and field tests, we have screened out the compound...
