Description
(1) technical field
The present invention relates to herbicide field, particularly to a kind of herbicidal composition for corn safety.
(2) background technology
Nicosulfuron, chemical name: 2-(4,6-dimethoxypyridin-2-base carbamoylamino sulphonyl)-N, N-diformazan
Base nicotiamide, rimsulfuron, chemical name: 1-(4,6-dimethoxypyridin-2-base)-3-(ethylsulfonyl-2-pyridine sulfonyl sulfonyl
Base) urea, above two material is the systemic herbicide that corn field is important, can planted subsequently by weeds stem and leaf and root absorption
Conduction in object, causes sensitive plant growth retardation, stem and leaf chlorisis, the most withered, generally 20-25 days dead.Cigarette is phonetic
Sulphur is grand, rimsulfuron has many good qualities, such as broad weed-killing spectrum, low price, activity height；And its shortcoming is in the case of hot and humid
Poisoning and medication optimum period short (comparatively safe to 5 leaf phase medications at Semen Maydis 3 leaf, to be suitable for insecticide spraying time short), easily occur；Different beautiful
Rice kind is variant to the sensitivity of nicosulfuron, rimsulfuron, and its safety order is Dens Equi type > flint corn > explosion jade
Rice > sweet corn.Sensitive to this agent to sweet corn, glutinous maize, pop corn and seed production corn, it is impossible to use.
The difference of corn variety limits the use of nicosulfuron, rimsulfuron, and it is fixed to need most corn variety
Alleviate, to spraying, the poisoning that cigarette is phonetic, which limits they large area mechanizations and use.Nicosulfuron, rimsulfuron and double benzene
After the salt of oxazole acid is compounding, the safety on special corn is greatly improved, to sweet corn and pop corn, seed production corn with
Sample safety.And also can field spraying entirely, use large-scale spraying apparatus alleviate can the burden of peasant, there is the biggest economy and society
Can benefit.
At present, conventional Herbicide antidote or safener have benoxacor, cloquintocetmexyl, fenchlorazole, fenclorim, solution grass
Peace, fluxofenim, furilazole, isoxadifen, mefenpyrdiethyl, naphthalene dimethyl anhydride, AMG 191(96420-72-3), solve grass
Nitrile etc..
The patent that CN1092189C introduction isoxadifen and ester and nicosulfuron thereof are used together, this patent system
The bis MSB p bis benzene oxazole acid of system is illustrated.Patent CN200580042762.7 describes rimsulfuron, nicosulfuron, Methanamide
Sulphur is grand, diflufenzopyr, Mesotrione or Mediben etc. and isoxadifen combination, it is possible to increase corn yield.Patent
CN201210028943.6 describes isoxadifen and ester 0.001g-0.5kg per hectare rimsulfuron, cigarette phonetic sulphur Methanamide
Sulphur is grand, Mesotrione, Mediben, diflufenzopyr 10g-3kg and chlopyrifos combination, is used for improving corn yield, reduces and chlopyrifos
Mixed risk.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of prepare simple, pacifying for Semen Maydis of using safety
Full herbicidal composition.
The present invention is achieved through the following technical solutions:
A kind of herbicidal composition for corn safety, it is characterised in that: its active component includes isoxadifen
Salt, nicosulfuron and/or rimsulfuron, wherein, the weight ratio of components of the salt of isoxadifen, nicosulfuron and rimsulfuron is
1:0-50:0-50, the chemical formula of the salt of isoxadifen is, wherein, M=K+, N (CH3)n, N (C2H5)n, N
(CH2CH2OH)n, NH2CH(CH3)2, n=1,2,3.
The more excellent scheme of the present invention is:
The weight ratio of components of the salt of described isoxadifen, nicosulfuron and rimsulfuron is 1:0-10:0-10.
In addition to active component, also include auxiliary agent, filler and surfactant.
Described compositions is wettable powder, water dispersible granules, dry suspending agent or oil-suspending agent.
The present invention compares isoxadifen, isoxadifen ethyl ester, the activity of isoxadifen acid potassium salt, finds double benzene
Oxazole acid potassium salt has higher detoxification ability, is especially under 4 times of nicosulfuron normal doses, and the suppression to Semen Maydis is minimum,
And the use age is wider, at Semen Maydis 2 leaf to 8 leaf phases, uses and all have good effect.
The product that the present invention describes can be the most blended in material in finished product preparation form, i.e. product.But compositions
Composition can also individually provide with preparation, directly mixes before use in container.
The compositions of the present invention can also contain other active constituent, and such as other has sterilization, parasite killing or herbicidal performance
Compound, it is also possible to mix with nematicide, protective agent, growth regulator, nutrient for plants or soil conditioner.
The compositions of the present invention can be used by common method, and as poured into a mould spraying or dusting, it generally uses
Method is stem and leaf spraying.
The present invention is prepared simply, uses safety, may be used for nicosulfuron, the sweet corn of rimsulfuron sensitivity, viscous jade
Rice, pop corn, seed production corn etc. and conventional corns more than 5 leaf phases, compositions is the safest to Semen Maydis, and usage amount is permissible
Reach common nicosulfuron, 4 times of rimsulfuron.

Embodiment 5:
Corn safety test method: put into by corn seed 5 pieces and be previously added a diameter of 10cm of sandy loam, height is
In the plastic flowerpot of 8cm, cover with soil and be placed in phjytotron, treat that temperature, to 3 to the 5 leaves outer phase, is adjusted to by Semen Maydis length
35 DEG C, and keep certain humidity.Each process is repeated 4 times, stem and leaf spraying treatment nicosulfuron and isoxadifen potassium salt each
Plant and process, and after 15 days, measure plant height, fresh weight.
Test plant: 6 leaf phase Semen Maydiss.
Treatment agent: process 1 and compare with processing 3, process 1 containing double benzene oxazole acid potassium salt, processes 3 and does not contains；Process 2 and process
4 compare, and process 2 containing double benzene oxazole acid potassium salt, process 4 and do not contain.
Dosage:
(1) 4% nicosulfuron suspending agent (embodiment 1), 180g/ mu；
(2) 6% nicosulfuron rimsulfuron suspending agents (embodiment 2), 90g/ mu；
(3) 4% nicosulfuron suspending agents, 180g/ mu；
(4) 6% nicosulfurons rimsulfuron suspending agent (autogamy), 90g/ mu；
(5) comparison: non-dispenser Semen Maydis.
Corn variety: step on sea 9 (step on sea plant industry), earnestly glue No. 1 (Heilungkiang academy of agricultural sciences), sweet glutinous 8010(Zhangye pioneer
Zhong Ye Co., Ltd), sweet No. 1 of Gansu Province (Dunhuang, Gansu Province kind industry seed), the kind of selection is sensitive to nicosulfuron
Kind.
Fresh weight preventive effect computing formula: preventive effect (%)=(1-processes fresh weight/comparison fresh weight) × 100.
Following table is that different corn variety is to different cigarette phonetic process preventive effect (suppression ratio) 15 days results.
Found out by upper table, after Semen Maydis processes 15 days, process 1 with processing 2 and all add isoxadifen potassium salt, at jade
In four sensitive varietieies of rice, Semen Maydis plant height and fresh weight all be there is no big impact, plant height preventive effect (suppression ratio) most 14.5%, fresh
Weight preventive effect, is 18.8% to the maximum, and does not adds isoxadifen potassium salt and process 3 and process 4, and plant height preventive effect is mostly at 30-50%, fresh
Weight preventive effect, at 30-40%, shows that external symptom plant substantially downgrades deformation, and yellow distorts.Visible isoxadifen potassium salt is obvious
Reduce the phonetic poisoning of cigarette, and the process 1 and 2 adding isoxadifen potassium salt uses safety on above-mentioned corn variety.
