Embodiment 1

[0049] Embodiment 1: 26% pyrazole flutter west wettable powder

[0050] Composed of components with the following mass fractions:

[0051] Pyrazosulfuron-methyl 2%

[0052] Promethazine 12%

[0053] West Grass 12%

[0054] Dispersant 3%

[0055] Suspending agent 3%

[0056] Wetting agent 1.5%

[0057] Inert filler to 100%.

[0058] Firstly, the dried pyrazosulfuron-methyl, procytazin and sigrazin raw materials are firstly mixed and crushed first, then the dried fillers, various auxiliaries, and raw drugs are measured and put into a double-screw mixer for mixing, and then crushed in a jet Machine or ultrafine pulverizer for continuous pulverization, the pulverized material is collected in the remixing mixer, and it can be fully mixed after running for a certain period of time.

[0059] The obtained mixed herbicide of the present invention has an appearance: loose powder with uniform color and composition without visible foreign impurities, suspension rate: pyrazosulfuron...

Embodiment 2

[0061] Embodiment 2: 50% pyrazole-popper-xime suspoemulsion

[0062] Consists of the following mass fractions

[0063] Pyrazosulfuron-methyl 10%

[0064] Promethazine 20%

[0065] West Grass 20%

[0066] Emulsifier 5%

[0067] Antifreeze 5%

[0068] Thickener 1%

[0069] Defoamer 0.2%

[0070] Deionized water to 100%.

[0071] The pyrazole, flutter, and west WP of embodiment 3~12:

[0072]

[0073] The present invention is not limited to be prepared as wettable powder, and corresponding auxiliary agents such as surfactants, dispersants, disintegrants, wetting agents, defoamers, and thickeners can be added to form suspending agents and water-dispersible granules. Because the corresponding auxiliary agent is available and known by those skilled in the art, as the dispersant can use commonly used sodium p-dodecylbenzenesulfonate and sodium polycarboxylate GEROPON T / 36DF, and the disintegrant can use polyvinylpyrrolidone Sokalan HP 62G, polysiloxane L-1000 can be used ...

Abstract

The invention discloses a weeding composite which belongs to the agriculture technical field of weedicide and is characterized in that the effective components thereof comprise pyrazosulfuron-ethyl, prometryn and simetryne which have low toxicity. The invention enlarges weeding spectrum, has a large application range, and can be suitable for various rice paddies like transplant fields, rice transplanting fields, and direct seeding fields, and the like. Meanwhile, the weeding composite can reduce the medicine dosage, save work force, improve the working production efficiency and is nonhazardous to rice.

Description

technical field [0001] The invention belongs to the agricultural technical field of herbicides containing heterocyclic compounds, and in particular relates to a herbicide containing active ingredients, which is suitable for selectively preventing beneficial plant crops such as rice weeds such as barnyardgrass, wild celery, bermudagrass, goosegrass, etc. Herbicidal composition for annual and perennial paddy field weeds. Background technique [0002] Weed damage in paddy field is an important factor affecting the high yield, stable yield and high quality of rice. There are many kinds of weeds in rice fields, especially those with wide distribution and serious damage. The most important weeds in rice fields are barnyardgrass, Qianjinzi, crabgrass, bermudagrass, sedge, moshangcai, special-shaped sedge, and dwarf sagittarius. In the past, manual weeding was often used, which not only required a lot of labor and cost, but also the control was not thorough and the effect was not g...
