Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of corn containing topramezone and the grand active component of thiophene ketone sulphur
Post-emergence complex weedicide.
Technical background
Corn is both the important cereal crops of China, is also important forage crop.In recent years, with animal husbandry, food
The development of the industries such as processing, wine-making industry and biodiesel, the market demand of corn is continuously increased.China's corn planting face in 2012
Product is only second to paddy rice up to 3994.9 ten thousand hectares, as second largest long-term cropping, and also increased trend.Corn field it is miscellaneous
Grass occurs generally, and species is various.Particularly there is serious, crop smothering occurring area Zhan Gai areas kind in the summer corn crop smothering of Yellow-huai river basin
The 82%~96% of area is planted, wherein medium above hazard area is up to 64~66%.Maize at Seedling Stage is the most serious by crop smothering, performance
For plant is short and small, bar spire yellow, so as to cause middle and later periods corn growth bad, Severe Reduction.
With the development of agricultural cience and farming techniques, the popularization and application of chemical herbicide are as saving of labor, time saving, cost-effective
One of strong well stimulation.Before seedling and after seedling two critical periods of early stage enter after broadcasting mostly for the chemical prevention of corn field weed
OK, typically applied before the leaf phase of corn 2.At present, corn herbicide kind is more, wherein representative for preventing and kill off corn field
The kind of weeds has nicosulfuron and mesotrione.But nicosulfuron has poisoning, mesotrione to some corn varieties
It is good to corn safety, but it is less desirable to grassy weed effect.
Topramezone (trade name bud is defended) biggest advantage is exactly security, and it has good to most of corn
Selectivity, including ordinary maize, corn, waxy corn, pop corn.And the whole growth period after maize seedling can be just
Often apply.
Topramezone has good preventive effect to most of annual corn field common weeds, especially grassy weed, also right
The malignant weeds such as dayflower, acalypha copperleaf have preferable prevention effect.Topramezone has broader use than conventional herbicide after seedling
Phase, peasant household can be allowed to emerge in appropriate weeds, dispenser when farming season.
But because topramezone is imported medicine, its import volume is limited and price is high, so limit it using.Other benzene azoles
Humulone is undesirable to broad leaved weed and Sha section weed control efficacy.
Thiophene ketone sulphur grand (thiencarbazone-methyl) is sulfonyl-amino-carbnyl triazolinone class herbicide, is acetyl
Lactic acid synthetase inhibitors.It is that can effectively prevent and kill off corn field grassy weed and broad leaved weed that thiophene ketone sulphur is grand.It is early before bud and after bud
Phase all can be used.
The content of the invention
Grassy weed can be prevented and kill off it is an object of the invention to provide one kind, broad leaved weed and nutgrass flatsedge, and effect can be prevented and kill off again
A kind of really good maize post-emergence compound herbicide containing topramezone, it is to succession crop safety.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：
It is a kind of containing topramezone and the grand maize post-emergence compound herbicide of thiophene ketone sulphur, the active component of the complex weedicide is
By topramezone and thiophene ketone sulphur is grand constitutes, the grand weight ratio of the topramezone, thiophene ketone sulphur is 0.1-80：0.1-80.
Further scheme, the topramezone and the grand weight ratio of thiophene ketone sulphur are 14-22：4-12.
Further scheme, the topramezone and the grand weight ratio of thiophene ketone sulphur are 18：8 or 20：6.
Further scheme, the topramezone and the grand quality of thiophene ketone sulphur and account for the 0.1 of the complex weedicide gross mass
~85%.
Further scheme, the formulation of the complex weedicide for dispersible oil-suspending agent, suspending agent, suspension emulsion, aqueous emulsion,
Microemulsion, missible oil, wettable powder or water dispersible granules.
The synergy after mixture is evaluated with the co-toxicity coefficient method of Sun Yunpei, topramezone, thiophene ketone sulphur grand two is as a result shown
Plant active component and press 14-22：The co-toxicity coefficient of 4-12 ratios compounding is all higher than 120, synergistic effect is reached, wherein with 18:8 Hes
