Description
Technical field
The invention belongs to pesticide fields, and in particular to one kind grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations and its application.
Background technique
Sugarcane is the main sugar crop in China, accounts for 85% or more of the long-term sown areas of sugar crops in China, output of sugar accounts for food
90% or more of sugared total output.Wherein the Guangxi 2014-2015, Yunnan, the big producing region sugarcane acreage in Guangdong three are respectively
98.4 ten thousand hm2,34.8 ten thousand hm2 and 1.5 ten thousand hm2, sugarcane production have become mainstay and the peasant of main producing region economic development
The main source increased income.But weeds are very harmful to its during sugarcane production, especially spring and summer sugarcane Feng Hangqian,
Due to sugarcane long-term exposed, weed growth is swift and violent, not only increases the production cost of weeding, weed control work cannot in time into
Row, will cause weeds and sugarcane contention moisture, nutriment and sunlight, and disease pest causes harm exacerbations, inhibit sugarcane normal growth and development, reduction
Sugarcane yield becomes the principal element for restricting sugarcane production.
The whole nation is registered with sugar-cane herbicide product based on single-dose product altogether at present, accounts for 75%, remaining is mixture product, agent
Type is mainly wettable powder, wherein single-dose product and mixture preparation containing ametryn account for entire sugar-cane herbicide registration quantity
35%, secondly it is 2 first 4 that single-dose product and mixture preparation containing diuron, which account for the 29% of entire sugar-cane herbicide registration quantity,
Chlorine and atrazine, account for 19% and 16% respectively.
Currently used for the herbicide drug kind and dosage form serious aging of sugarcane field weeds chemical control, when numerous sugarcane growers are long
Between using same herbicide carry out weeding operation, due to Weed Resistance increase year by year cause sugar-cane herbicide dosage increase be exceedingly fast,
Also cause to remain in soil simultaneously and the quantity of crop residual herbicide is continuously increased.
Summary of the invention
The purpose of the present invention is to provide a kind of component is reasonable, drug cost is low, is not likely to produce the herbicide group of drug resistance
Object is closed, there is positive effect to slow down Weed Resistance, reduce drug dosage etc..
The present invention provides following technical scheme
One kind grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations, active constituent are made of component A and component B；Component A is sulfone pyrrole
Careless azoles, component B are diuron；The weight proportion of the component A and component B is 1:2-6.
The grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations of the present invention, it is characterised in that: the component A and component B
Weight proportion be 1:2-4.
The grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations of the present invention, it is characterised in that: the component A and component B
Weight proportion be 1:2,1:3,1:4.
The grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations of the present invention, it is characterised in that: active constituent in composition
Total weight percentage composition be 1-75%.
The grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations of the present invention, it is characterised in that: active constituent in composition
Total weight percentage composition be 15-60%.
The present composition can be prepared into adaptation dosage form, preferred dosage form wettable powder with agriculturally acceptable auxiliary combination
Agent, missible oil, suspending agent, water dispersible granules etc..Auxiliary agent of the present invention include emulsifier, dispersing agent, wetting agent, binder,
Disintegrating agent, thickener, stabilizer, antifreezing agent, defoaming agent filler etc..
The grass azoles of pyrrole containing sulfone and diuron Herbicidal combinations of the present invention are used to prevent and kill off the purposes of sugarcane field weed.It is preferred that
The weeds be preferably gramineae weed, broadleaf weeds.The weeds include barnyard grass, herba digitariae, herba eleusines indicae, the rhizome of nutgrass flatsedge, Chenopodiaceae,
Ageratum conyzoides, ivy glorybind, ring dish etc..
The present invention obtains following advantageous effects:
Composition of the present invention can effectively reduce the generation of herbicide resistance, expand degrass spectrum, in addition of the present invention
Herbicidal combinations have significant synergies, and can effectively reduce the dosage of active constituent, reduce environmental pollution.
Specific embodiment
Below with reference to embodiment, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Embodiment 1: sulfone pyrrole grass azoles and diuron Herbicidal combinations are to herba digitariae indoor toxicity test.
Test method: selecting uniform weeds herba digitariae seed, and vernalization is to showing money or valuables one carries unintentionally in biochemical cultivation case.Dry powder will be shone
Sugarcane field soil after broken is fitted into plastic tub, respectively by weed seed uniform broadcasting Yu Tubiao, is covered about 0.5 cm fine earth, is set temperature
Routine culture in room carries out final singling in the weeds l-2 leaf phase, and every basin retains relatively uniform 25 plants of seedling of growth size, density, in
The herba digitariae 5-6 leaf phase carries out reagent spray processing.Referring to " farm-chemical indoor determination test rule " (People's Republic of China's agricultural
Portion, 2007), weigh or measure respectively herbicide a certain amount, be configured to series of concentrations by spouting liquid, using quantitative sprayer into
The uniform cauline leaf of row is spraying, and 4 repetitions of every processing are handled with clear water and compared (CK), handles routine culture in postposition greenhouse.After medicine
2 1d measurement weeds respectively handle the fresh weight of above-ground plant parts and calculate fresh weight inhibition rate, with inhibiting rate probability value (y) and concentration
Logarithm (x) establishes regression equation (y=a+bx), finds out different herbicides and measures (ID50) in the inhibition of herba digitariae, then according to Sun Yunpei
Method calculates co-toxicity coefficient (CTC).As CTC < 80, then composition shows as antagonism, as 80 < CTC < 120, then composition
Summation action is shown as, as CTC > 120, then composition shows as synergistic effect.Fresh weight inhibition rate (%)=(control aerial part
Fresh weight one handles aerial part fresh weight)/control aerial part fresh weight x100.
Table 1: sulfone pyrrole grass azoles and diuron Herbicidal combinations are to herba digitariae indoor toxicity test
