Embodiment 1

[0041] Example 1: Preparation of 16% Glycyrrhizin-Cyhalofop-ethyl dispersible oil

[0042]

[0043] Solvent is used to dissolve glycyrrhetin-oxafen, cyhalofop-methyl and isoxadifen and mix together, and then add emulsifier and dispersant to stir and mix.

Embodiment 2

[0044] Example 2: Preparation of 30% Glycyrrhizin-Cyhalofop-Powder WP

[0045]

[0046] The above components are mixed together, pulverized, stirred and mixed.

Embodiment 3

[0047] Example 3: Preparation of 40% Glycyrrhizin Glycyrrhizin Cyhalofop-methyl Soluble Liquid

[0048]

[0049] It is prepared by mixing glycyrrhetin-oxafen, cyhalofop-ethyl and isoxadifen with a cosolvent, adding a surfactant, and finally adding a solvent and stirring.

Abstract

The invention relates to a refined oxazole glycyrrhizamide weeding composition added with a safener. The refined oxazole glycyrrhizamide weeding composition comprises three active ingredients A, B andC, The weeding composition is used for preventing and removing weeds in paddy fields and reducing damage to paddy rice. The composition can obviously reduce or even eliminate the damage of herbicidesincluding the isoxazole glycyrrhizamide and the cyhalofop-butyl to rice, has a certain promotion effect on the growth of the rice, and does not influence the prevention and removal effects of the isoxazole glycyrrhizamide and the cyhalofop-butyl on weeds in a paddy field at the same time.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a herbicidal composition of oxaazole-glycyrrhizin added with a safener. Background technique [0002] Rice is an annual gramineous plant, which is produced on all continents except Antarctica. Rice is not only the most important food crop in my country, but also one of the main food crops in the world. The world's rice cultivation area is about 145 million hectares. The sown area of ​​rice in my country accounts for 1 / 4 of the country's grain crops. Regardless of planting area or output, rice ranks first among food crops in my country. However, rice fields in all rice-growing regions in my country have suffered from weed damage to varying degrees. Among them, the area of ​​moderate weed damage accounts for more than 46% of the total planting area of ​​rice, and the area of ​​severe weed damage accounts for more than 11.5%. These weeds compete with rice in all aspects and cause damage...
