Example Embodiment

[0015] Example 1: Preparation of 15% cyhalofop-fen-pyrimidin emulsifiable concentrate.

[0016] Specific formula:

[0017] Cyhalofop-butyl 10%

[0018] Bispyribac 5%

[0019] Agricultural milk 500 (emulsifier) ​​10%

[0020] Xylene (solvent) 75%

[0021] The composition is weighed according to the above proportions of cyhalofop-methyl and cyhalofop-fen. According to the product form to be prepared, it is an emulsifiable concentrate formulation, and the emulsifier and solvent of the proprietary formula are used. After fully mixing in an enamel stirring tank, add The emulsifier in the additive is stirred again for 30 minutes. After passing the inspection, the finished product is obtained in a large package, and then it is packaged again.

[0022] The control effects of 25 ml / mu, 37.5 ml / mu and 50 ml / mu of the preparations prepared according to the above ratios on rice barnyardgrass, sagebrush and sedge are more than 90%, which are better than those of single use, see the...

Example Embodiment

[0035] Example 2: Preparation of 12% cyhalofop-fen-pyrimidin emulsifiable concentrate

[0036] Specific formula:

[0037] Cyhalofop-butyl 8%

[0038] Bispyribac 4%

[0039] Agricultural milk 500 (emulsifier) ​​10%

[0040] Xylene (solvent) 78%

[0041] The production method is the same as Example 1.

[0042] The control effects of 30 ml / mu, 45 ml / mu and 60 ml / mu of the preparations prepared according to the above proportions against rice barnyard grass, sagebrush and sedge are all over 90%, and are also better than cyhalofop-butyl and The two products of pyrifenapyr are used alone, see Tables 4 and 5 below.

Abstract

The invention discloses a weed killer composition with the function of broad-spectrum weeding, and relates to the technical field of agricultural production. The composition disclosed by the invention consists of effective constituents, emulsifiers and solvents, and is in the dosage form of missible oil. The composition is characterized in that the effective constituents of the composition are cyhalofop-butyl and pyriminobac-methyl. The cyhalofop-butyl and the pyriminobac-methyl are compounded in the composition, so that the composition has the function of high-efficient and broad-spectrum weeding, the weeding scope is extended, and the control effect for barnyard grasses, semen euphorbiae, sedges, convexutricle sedge herbs, heleocharis plantagineiformis, sagittaria pygmaea, alternanthera philoxeroides and four-peduncles four-circumference paspalum distichum, and the like in direct seeding paddy fields is good, and better than that of using two single dosage varieties of the cyhalofop-butyl and the pyriminobac-methyl. The composition can be widely used for preventing and killing off various weeds in the rice direct seeding fields.

Description

technical field [0001] The invention relates to the technical field of agricultural production, especially the technical field of herbicide production. Background technique [0002] Rice is the main food crop in my country, and the country's rice planting area has been stable at about 450 million mu for many years. With the continuous popularization and application of rice light cultivation techniques, the development of direct-directed rice is particularly rapid. Due to its huge advantages of saving labor and cost and liberating rural productivity, it has gradually become a rice cultivation method with broad development prospects in major rice producing areas in my country. Due to the cultivation methods and characteristics of direct-directed rice fields, the occurrence of weed damage in direct-directed rice fields is very prominent. [0003] Weeds in direct seeded paddy fields are dominated by Gramineae weeds such as A. chinensis and barnyardgrass, which are abundant and...
