Embodiment 1

[0026] Embodiment 1. prepares water-dispersible granules (the sum of the raw material parts for preparing pesticides is 100 parts)

[0027] With 78 parts by weight of the active ingredient mixture (35 parts by weight of cyhalofop-ethyl+43 parts by weight of bensulfuron-methyl), 3 parts by weight of sodium lauryl sulfate, 4 parts by weight of polyvinyl alcohol, 3 parts by weight of calcium lignosulfonate and the remaining amount of kaolin.

[0028] After the above ingredients were mixed and ground into a fine powder in a plug-type disc mill, the powder was granulated in a fluidized bed by spraying water as the granulating liquid.

Embodiment 2

[0029] Embodiment 2. preparation of wettable powder (the sum of the raw material parts for preparing pesticides is 100 parts)

[0030] 55 parts by weight of the active ingredient mixture (39 parts by weight of cyhalofop-methyl+16 parts by weight of bensulfuron-methyl), 3 parts by weight of sodium dodecylbenzenesulfonate, 5 parts by weight of sodium sulfonate of alkylnaphthalene formaldehyde condensate , 1 part by weight of glycerin, and the remainder of white carbon black is mixed, and through superfine pulverization, the powder particles reach the fineness requirement, and use a double-helix mixer and a coulter mixer to mix repeatedly to make the product Mix well to prepare the high content dosage form.

Embodiment 3

[0031] Embodiment 3. preparation of granules (the sum of the raw material parts for preparing pesticides is 100 parts)

[0032] With 65 parts by weight of active ingredient mixture (27 parts by weight of cyhalofop-ethyl+38 parts by weight of bensulfuron-methyl), 8 parts by weight of liquid paraffin, 5 parts by weight of polyvinyl alcohol, 2 parts by weight of calcium stearate, For the remaining amount of clay, mix the above materials to obtain 100 parts of powder mixture, add appropriate amount of water, mix with a small kneader, then granulate, granulate with a granulator, dry, and sieve to obtain the preparation.

Abstract

The invention discloses a weeding composition containing cyhalofop-butyl and bensulfuron-methyl for paddy field, which comprises active ingredient a and active ingredient b, wherein the active ingredient a is cyhalofop-butyl, the active ingredient b is bensulfuron-methyl, the weight ratio of the active ingredient a to the active ingredient b is 1-90:90-1; preferably, the weight ratio of the active ingredient a to the active ingredient b is 1-50:50-1, and particularly preferred, the weight ratio of the active ingredient a to the active ingredient b is 1-10:10-1. The active ingredients of the composition account for 11 to 95 percent of the total weight of the composition, and the balance is agriculturally acceptable pesticide adjuvant.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicidal composition with improved performance, in particular to a herbicidal synergistic composition. Background technique [0002] Cyhalofop-ethyl is the only aryloxyphenoxypropionic acid herbicide with high safety to rice. Cyhalofop-ethyl is also a systemic conductive herbicide, which is absorbed by the leaves and leaf sheaths of plants, conducts in the phloem, accumulates in the meristem area of ​​plants, inhibits acetyl-CoA carboxylase, stops fatty acid synthesis, and promotes cell growth The division cannot be carried out normally, the membrane system and other lipid-containing structures are destroyed, and finally the plant dies. The speed of action of cyhalofop-ethyl is relatively slow, and it generally takes 1 to 3 weeks to kill the weeds. In rice, cyhalofop-methyl can be rapidly degraded into a diacid state that is inactive to acetyl-CoA carboxylase, so ...
