Embodiment 1

[0052] Cyhalofop-butyl 3%, quinclorac 30%, wetting agent pulling powder 5%, dispersing agent NNO 12%, talc 4%, and the balance being kaolin. The above formula is coarsely pulverized in proportion to enter into a mixer to mix evenly, and after jet pulverization, a 33% Cyhalofop-ethyl quinclorac wettable powder is prepared.

Embodiment 2

[0054] Cyhalofop-butyl 5%, quinclorac 15%, emulsifier tristyrylphenol polyoxyethylene polyoxypropylene ether (ie emulsifier 1601#) 15%, wetting agent p-oleamidoanisole sulfonic acid Sodium 5%, dispersant alkylphenol formaldehyde resin polyoxyethylene ether sulfate 4%, bentonite 3%, xanthan gum 0.1%, silicone defoamer 0.4%, glycerin 5%, the balance is deionized water . The above formula is pre-pulverized in proportion, then added to a sand mill for grinding, and mixed with high shear to prepare a 20% cyhalofop-butyl-quinclorac suspension agent.

Embodiment 3

[0056] Cyhalofop-butyl 10%, quinclorac 10%, sodium lauryl sulfate 6%, polycarboxylate 4%, sodium chloride 2%, polyethylene glycol 3%, and the balance is kaolin. The above formula is dry pulverized, granulated, dried and sieved according to the proportion to prepare 20% Cyhalofop-ethyl quinclorac water dispersible granules.

Abstract

The invention discloses a cyhalofop-butyl-containing pesticide composition, which comprises common additives, cyhalofop-butyl and quinclorac, wherein active ingredients are the cyhalofop-butyl and the quinclorac; the mass-part ratio of the cyhalofop-butyl to the quinclorac is 1:1-1:50; and the accumulative mass percentage of the active ingredients in a preparation is 1 to 70 percent. The cyhalofop-butyl-containing pesticide composition is applied to the prevention and control of farmland weeds, particularly annual gramineous weeds in paddy field. The composition has the prevention-control effect obviously improved compared with that of single agents, and reduces the using dosage of pesticide and cost.

Description

technical field [0001] The pesticide composition involved in the present invention uses cyhalofop-methyl and quinclorac as active ingredients, and is used for the application of preventing and controlling weeds in farmland. Background technique [0002] Quinclorac (quinclorac) is a specific selective herbicide for the control of barnyardgrass in paddy fields, with outstanding effect on barnyardgrass at the 4-7 leaf stage. It has strong selectivity and wide range of application period, and one application can control barnyardgrass in the whole rice growth period. It can also effectively control duck tongue, cress and so on. The compound can be absorbed by germinated seeds, roots and leaves, and has the characteristics of hormonal herbicides, and the symptoms are similar to those of auxin substances. The young leaves of the affected barnyardgrass showed slight chlorosis, and the leaves appeared longitudinal stripes and curved. When the barnyard grass is damaged, the leaves ...
