Embodiment 1

[0027] Example 1: 1% cyhalofop-methyl + 5% mesotrione + 20% sodium 2-methyl-4-chloride emulsifiable concentrate

[0028] Cyhalofop-methyl 1%; Mesotrione 5%; Sodium 2M-4Cl 20%; Conventional emulsifier 10-30%; Conventional solvent 20-50%; Conventional synergist 1-5%. Fluoropate, mesotrione and sodium 2-methyl-4-chloride are added to the solvent to dissolve completely, and then emulsifier and synergist are added and stirred evenly to form a uniform and transparent oily liquid, which can be filled to produce the composition of the present invention. Cream preparations.

Embodiment 2

[0029] Example 2: 5% cyhalofop-methyl + 7.5% mesotrione + 15% sodium 2-methyl-4-chloride wettable powder

[0030] Cyhalofop-methyl 5%; Mesotrione 7.5%; Sodium Methochloride 15%; Sodium Lauryl Sulfate 10%; Sodium Lignosulfonate 5%; White Carbon Black 10%; , mix the above components in proportion, grind and pulverize to prepare wettable powder.

Embodiment 3

[0031] Example 3: 10% cyhalofop-methyl + 50% mesotrione + 10% 2M 4 chloride sodium water emulsion

[0032] Cyhalofop-methyl 10%; Mesotrione 50%; Mesotrione 10%; N-Methylpyrrolidone 25%; Calcium dodecylbenzenesulfonate 5%; Nongru 600# 7%; to 100%, the above oil phase components are mixed and then added to the water phase to obtain a water emulsion.

Abstract

The invention provides a synergistic weeding composition. The weeding composition comprises the following active components cyhalofop butyl, mesotrione, and MCPA sodium and according to a mass ratio 1-50:1-50:1-50; the mass of cyhalofop butyl, mesotrione and MCPA sodium in the preparation is 1-80% of the total mass of the whole preparation; the dosage forms of the weeding composition comprise missible oil, suspending agent, wettable powder, water dispersible granule, emulsion in water, micron emulsion, and microcapsule. The weeding composition has wide weed control spectrum, and can be effectively used for controlling many broad leaf weeds and nutgrass flatsedge 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 cyhalofop-ethyl, mesotrione and sodium 2-methyl-4-chloride. 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 experiments, we screened out...
