Abstract
The herbicide for zero-tillage rice field for application before seeding includes bensulfuron-methyl, butachlor or its analogue pretilachlor, metolachlor, glyphosate isopropyl amine salt and adsorbent silica white, with the effective component weight ratio of beasulfuron-methyl, butachlor and glyphosate isoproply amine salt being 1 to 2-100 to 10-250 and weight ratio between bensulfuron-methyl and silica white being 1 to 1-300. Once application can kill the weed of zero-tillage rice field before and after seeding so as to simplity the cultivation process.
Description
The present invention relates to a kind of weed killer herbicide and production method thereof, particularly a kind of weed killer herbicide and production method that is suitable for no-tillage paddy field.
Existing steriland herbicide glyphosate, glyphosate isopropyl amine salt and gram do not have track and all only can kill the weeds that germinated before no-tillage ground paddy rice is broadcast, and be then invalid to the weeds that sprout behind the rice growing; Existing other herbicides for use in paddy can only kill and wound the weeds seedling of firm sprouting, then can not prevent and kill off the weeds that have been grown in the field before sowing.
The objective of the invention is: a kind of herbicide for zero-tillage rice field and manufacture method thereof are provided, this weed killer herbicide can not only be killed the residual weeds of the preceding stubble of zero-tillage rice field, can prevent and kill off simultaneously single broadleaf weed of field germinating behind seed rice premature rice again, solving zero-tillage rice field needs first stubble-cleaning to sow the difficult problem of weeding again, simplifies no-tillage rice culture technology.
Technical scheme of the present invention is: a kind of herbicide for zero-tillage rice field includes Bensulfuron-methyl, butachlor or the isoreagent third careless amine, Dou Er, the white carbon black of glyphosate isopropyl amine salt and adsorbent, wherein Bensulfuron-methyl effective active components and butachlor or the isoreagent third careless amine, Dou Er, the weight ratio of glyphosate isopropyl amine salt effective active components is 1: 2-100: 10-250, Bensulfuron-methyl is 1 with the weight ratio of white carbon black: 1-300.

When calculating proportioning, press the content of Bensulfuron-methyl in the Bensulfuron-methyl pulvis, the content of butachlor in the butachlor ec, the content meter of glyphosate isopropyl amine salt claims in the glyphosate isopropyl amine salt pulvis.The metering of butachlor isoreagent is also like this.
Butachlor can adopt commercially available homemade 60% butachlor ec, contains butachlor effective ingredient 60 grams in promptly per 100 gram butachlor ecs.
Bensulfuron-methyl can adopt commercially available homemade 10% Bensulfuron-methyl pulvis, contains Bensulfuron-methyl effective ingredient 10 grams in promptly per 100 gram Bensulfuron-methyl pulvis.
41,%00 grass that glyphosate isopropyl amine salt can adopt commercially available homemade commodity 41% glyphosate isopropyl amine salt pulvis or chemical plant, Suzhou to produce, 41% farming clear or that U.S. Monsanto Company produces reaches or with the former powder processing of glyphosate isopropyl amine salt, as 1 kilogram of glyphosate isopropyl amine salt pulvis or hundred grass are clear or farming contains glyphosate isopropyl amine salt effective ingredient 410 grams in reaching.
A kind of herbicide for zero-tillage rice field also includes filler precipitated calcium carbonate or diatomite or kaolin or activated carbon or potter's clay, and the weight ratio of glyphosate isopropyl amine salt and above-mentioned filler is 1: 0.2-5.
A kind of manufacture method of herbicide for zero-tillage rice field, earlier load weighted butachlor ec makes it be adsorbed in load weighted by weight ratio fineness with spray-on process to pass through in the white carbon black of 250 purposes 95% or more by weight ratio, stir white carbon black while spraying, and then, get finished product with it and by the good glyphosate isopropyl amine salt pulvis uniform mixing of proportioning weight weighing.
Major advantage of the present invention is: is applicable to zero-tillage rice field sowing previous crops one-time weeding, can effectively goes out to remove and broadcast preceding weeds in field, can prevent and kill off the weeds of broadcasting the back germinating again, and broad weed-killing spectrum, preventive effect is good, can simplify the zero-tillage rice field culture technique.
