Description
Technical field
The invention belongs to the agricultural herbicide field, particularly contain the herbicide for paddy field of clefoxidim and penoxsuam complex composition.
Background technology
Clefoxidim, chemical name are 2-[1-[2-(4-chlorophenoxy) propoxyl group imino group] butyl-3-hydroxyl-5-[tetrahydrochysene-2H-thiapyran (thia)-3-yl] hexamethylene-2-ketenes, structural formula is:
This product is the cyclohexenone analog weed killer herbicide by BASF AG's exploitation.Cyclohexenone compounds is used for the dry land weeding mostly, and clefoxidim is unique a kind of cyclohexenone compounds for paddy field weed-killer of finding at present.It belongs to the paddy field broad-spectrum herbicide, is mainly used in preventing and kill off rice field grassy weed such as barnyard grass, Lan Macao, lady's-grass, moleplant seed, green foxtail, Rottboellia exaltata L. F etc., to the equal safety of direct seading rice and transplanting rice.Clefoxidim is the ACCase inhibitor, is absorbed by plant rapidly behind the foliage application and shifts, and transfers to growing point at phloem, suppresses the growth of sprouting, weeds elder generation chlorosis, and rear variable color is withered, and is fully withered in general 2～3 weeks, fool proof to ecotope.Field test results shows in China, with 7.5% clefoxidim missible oil 675ml/hm
2Cauline leaf is processed, and can reach 100% to the preventive effect of Portugal's stem bent grass.
Penoxsuam, chemical name be 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) triazole-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN), structural formula is:
This product is to use weed killer herbicide behind the seedling of being developed by U.S. Tao Nongke company, and it belongs to the triazolopyrimidine sulfonamide weed killer herbicide, works by suppressing acetolactate synthestase (ALS).Penoxsuam is the rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass (comprising the barnyard grass to Stam F-34, dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), moleplant seed and annual sedge weed, and effective to numerous broad leaved weeds, give birth to different stamen flower, carp intestines, sesbania, ring flower, Monochoria vaginalis etc. such as the natural pond.Lasting period reaches 30～60 days, and a drug can the weeds harm of full season of basic controlling.Simultaneously, it also can prevent and kill off anti-bensulfuron-methyl weeds in the rice field, and many broad-leaveds and sedge weed and barnyard grass etc. are had residual activity, for composing the widest kind with herbicide in the weed killer herbicide in present rice field.Penoxsuam is translocated herbicide, strong inhibitor of acetolactate synthetase through cauline leaf, young shoot and Root Absorption, conducts to meristematic tissue by xylem and phloem, suppress plant strain growth, make the growing point chlorosis, 7～14d terminal bud reddens necrosis after processing, 2～4 all plant are dead, it is strong inhibitor of acetolactate synthetase, and medicament presents slower, needs the certain hour weeds just dead gradually.Penoxsuam is applicable to direct-sowing dry field, water direct seeding field, rice seedling bed and rice transplanting, the rice transplanting cultivation field of paddy rice.Penoxsuam is fool proof to paddy rice, 10 rice varieties were sprayed with 70ga.i./hm2 dosage in 2～3 leaf phases in the U.S. with 2006 in 2005, no matter the result is rice plant height degree, heading stage and the equal no significant difference of output, and this shows that all kinds all have stronger anti-patience.When ultrahigh dose, in early days the growth of rice root there is certain inhibitory action, but recovers rapidly, do not affect output.
With the composite weed killer herbicide of penoxsuam dichloro quinolinic acid, mesotrione, cyhalofop-butyl and azoles humulone, pyrazosulfuron etc. are arranged in the prior art; The weed killer herbicide composite with clefoxidim do not have report and patent.
Through retrieval, do not find the document of clefoxidim and the composite patent of penoxsulam herbicide.
The inventor has filtered out the compounded combination of clefoxidim and penoxsuam through a large amount of desk research and field experiment, and various formulation products have been made in these combinations, thereby proposes the present invention.
