Embodiment 1

[0015] Example 1: Preparation of 12% cyhalofop-butyl saflufenacil EC formulation:

[0016] Weigh 8 kg of cyhalofop-butyl, 4 kg of saflufenacil, 10 kg of agricultural milk (emulsifier) ​​10 kg, and 75 kg of xylene (solvent). After mixing them thoroughly in an enamel stirring tank, add the emulsifier in the additives , Stir again for 30 minutes, after passing the inspection, the finished product will be packaged.

[0017] The 25 ml / mu, 37.5 ml / mu, and 50 ml / mu formulations prepared according to the above ratio have a control effect of more than 90% on rice barnyardgrass, calamus and sedge, which is better than single use.

[0027] Example 2: Preparation of 10% cyhalofop-butyl saflufenacil EC formulation:

[0028] Weigh 7 kg of cyhalofop-butyl, 3 kg of saflufenacil, 10 kg of agricultural milk (emulsifier) ​​10 kg, and 78% kg of xylene (solvent). After mixing them thoroughly in an enamel stirring tank, add the additive Emulsifier, stir again for 30 minutes, after passing the inspection, the finished product will be packaged.

[0029] The 30 ml / mu, 45 ml / mu, and 60 ml / mu formulations prepared according to the above ratio have more than 90% control effects on rice barnyardgrass, calamansi, and sedge, and are also superior to cyhalofop and The two products of saflufenacil are used alone.

Abstract

The invention discloses an emulsion preparation having a broad-spectrum synergistic weeding effect, relating to the technical field of the production of herbicides. After being compounded by cyhalofop butyl ester and pyribenzoxim, the emulsion preparation has the efficient broad-spectrum weeding effect; meanwhile, the weeding range is expanded, and the emulsion preparation has relatively good preventing-treating effects on multiple weeds such as barnyard grass of directly-seeded paddy fields, semen euphorbiae, nutgrass flatsedge, convexutricle sedge herb, scripus triqueter, sagittaria pygmaea, alternanthera philoxeroides, four-stalk four-week paspalum paspaloides and the like than the use effects of two single dosages, namely cyhalofop butyl ester and pyribenzoxim. The emulsion preparation can be widely applied to the control of various weeds in the directly-seeded paddy fields.

Description

technical field [0001] The invention relates to 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 early, and are the most harmful to rice, followed by broad...
