Embodiment 1

[0050] Cyhalofop-ethyl 3%, quinclorac 30%, wetting agent pull-off powder 5%, dispersant NNO 12%, talcum powder 4%, and the balance is kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed uniformly, and then jet pulverized to obtain 33% cyhalofop-quinclorac wettable powder.

Embodiment 2

[0052] Cyhalofop-ethyl 5%, quinclorac 15%, emulsifier tristyrylphenol polyoxyethylene polyoxypropylene ether (ie emulsifier 1601#) 15%, wetting agent p-oleylamino anisole 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-crushed according to the proportion, then put into a sand mill for grinding, and then prepared after high-shear mixing to prepare 20% cyhalofop-quinclorac suspension concentrate.

Embodiment 3

[0054] Cyhalofop-ethyl 10%, quinclorac 10%, sodium lauryl sulfate 6%, polycarboxylate 4%, sodium chloride 2%, polyethylene glycol 3%, and the balance is kaolin. Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 20% cyhalofop-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-ethyl and quinclorac as active ingredients to prevent and control farmland weeds. Background technique [0002] Quinclorac is a specific and selective herbicide for controlling barnyardgrass in paddy fields, and has an outstanding effect on barnyardgrass at the 4-7 leaf stage. The selectivity is strong, and the application period is wide, and one application can control the barnyardgrass in the whole growth period of rice. It can also effectively control duck tongue grass, cress and so on. The compound can be absorbed by germinated seeds, roots and leaves, has the characteristics of a hormone-type herbicide, and has similar symptoms to auxin substances. The young leaves of the damaged barnyardgrass were slightly chlorotic, and the leaves appeared longitudinal stripes and curved. After the sandwich barnyardgrass is injured, the leaves turn green and turn purple-brown to dead; ...
