Embodiment 1

[0023] Formulation Example 1 (20% rimsulfuron-cyhalofop-ethyl wettable powder)

[0024]

[0025]

[0026] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 20% rimazansulfuron-cyhalofop-ethyl wettable powder.

Embodiment 2

[0027] Preparation Example 2 (22% rimsulfuron-cyhalofop-ethyl suspension concentrate)

[0028]

[0029] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 22% rimsulfuron-cyhalofop-ethyl suspension concentrate.

Embodiment 3

[0030] Formulation Example 3 (30% rimsulfuron-cyhalofop-ethyl water-dispersible granules)

[0031]

[0032] Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 30% rimsulfuron-cyhalofop-ethyl water-dispersible granules.

[0033] Preparation Example 4: (18% rimsulfuron-cyhalofop-ethyl oil suspension concentrate)

[0034]

[0035] Dissolve the original drug, solvent and emulsifier in the above formula into a uniform oil phase; mix under high-speed stirring to prepare 18% rimsulfuron-cyhalofop-ethyl oil suspension concentrate.

Abstract

The invention discloses a weeding composition containing orthosulfamuron and cyhalofop-butyl. The effective components of the weeding composition is the orthosulfamuron and the cyhalofop-butyl, and the weight ratio of the orthosulfamuron to the cyhalofop-butyl is (10:1)-(1:10). The weeding composition has the advantages that the annual weed controlling effect of the weeding composition is increased evidently as compared with that of a single-component weed killer, the use amount of agricultural chemicals is lowered, the adverse influence of the agricultural chemicals on the ecological environment is reduced, and the weeding composition is significant to the comprehensive treatment of weed resistance and huge in economic and social benefits.

Description

technical field [0001] The invention relates to a paddy field herbicidal composition, which takes rimsulfuron-methyl and cyhalofop-ethyl as active ingredients and is used for controlling annual weeds in paddy fields. Background technique [0002] Chemical weed control is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Fifamisulfuron belongs to the sulfonylurea herbicides. By inhibiting the acetolactate synthase (ALs) of weeds, it prevents the synthesis of branched-chain amino acids in plants, thereby preventing the synth...
