Description
Technical field
The present invention relates to technical field of pesticide, more particularly, to the dispersible oily suspension composition of one kind, preparation method and
Using.
Background technique
Wheat is the general designation of wheat system plant, is monocotyledon, is a kind of grass family plant planted extensively all over the world
Object, the caryopsis of wheat are one of staple foods of the mankind, can make the foods such as bread, steamed bun, biscuit, noodles after wearing into flour；Fermentation
After can be made into beer, alcohol, white wine (such as vodka), or raw matter fuel.Wheat rich in starch, protein, fat, minerals,
Calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C etc..Wheat is one of three big cereal, is almost eaten entirely,
Only used there are about 1/6th as feed.The Yellow Basin and the Yangtze River is the area of earliest cultivated wheat in the world, and China is that the world is earliest
Plant one of the country of wheat.Wheat in 2010 is the cereal crops (6.51 hundred million tons) that total output occupies second in the world, only secondary
In corn (8.44 hundred million tons).
It is reported according to national farmland weed study group, China's wheatland crop smothering area accounts for 55% of cultivated area or more, wherein
It seriously endangers area and accounts for 28%, lost units accounts for the 15% of wheat total output.Winter wheat main weeds have 30 kinds or so, Huaihe River with
South is mainly based on gramineae weed, such as amur foxtail, Alopecurus, herba bromi japonici, annual bluegrass, hard grass, caput grass, Chinese silvergrass.It is wealthy
Leaf weeds mainly have clearvers, ox chickweed, Veronica, crack rice neat, pale persicaria, the tongue of sparrow grass, common vetch etc..Huanghuai Area wheatland
Weeds type is more, and group is complicated.The weeds type of rice wheat rotation wheatland is similar to south, amur foxtail and Alopecurus be it is more,
The harm such as part wheatland hard grass, caput grass, wild avena sativa, Chinese silvergrass and herba bromi japonici are serious.Huang-Huai-Hai early makees winter wheat field weed, mainly with pig
Bring disaster to calamity, sarson, Descurainia sophia, common vetch, corn gromwell, shepherd's purse, wartwort, Veronica, field bindweed, field thistle, rice crock, Chenopodiaceae, small
Based on Chenopodiaceae, plaque storage and benbie.
The prior art is disclosed dicamba, tribenuron-methyl does suspension etc., but its except wheat weeds effect it is undesirable, while also not
See the report of dispersion oil-suspending agent, is badly in need of on pesticide market except a kind of good environmental protection of wheat weeds effect and efficient dispersed oil
Suspending agent dosage form.

Picloram-fluroxypyr preparation weeding preventive effect.
Each active constituent is due to composition, structure, the difference of physicochemical property after different herbicidal activity component mixing, so that respectively
Synergy between active constituent is typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly
Effect is cooperated between different material, the effect generated is greater than the sum total of each ingredient effect；And summation action is exactly it
The effect of generation is equal to the sum total of each ingredient effect；Antagonism refer to two kinds of material effects when living organism, a kind of object
The phenomenon that matter interferes the effect of another substance, or the effect of interfering with an opponent each other, declines general effect.
It evaluates two kinds of different mixed interactions of herbicidal activity component and generallys use co-toxicity coefficient method, wherein altogether
Malicious coefficient (CTC) >=120 shows as synergistic effect；()≤80 CTC show as antagonism to co-toxicity coefficient；80 < co-toxicity coefficient
(CTC) < 120 summation action is shown as.The present invention calculates co-toxicity coefficient evaluation chlorine ester sulphur grass according to Sun Yunpei (Sun Y-P) method
Amine and fomesafen mixed effect, co-toxicity coefficient are all larger than 120, show as apparent synergistic effect.
The combination of picloram, fluroxypyr has good synergistic effect, has very to wheatland common weed
High control efficiency, reduces the dosage of effective component, and application field is extensive.In addition, Herbicidal combinations provided by the invention exist
When preparing herbicide, simple process, auxiliary material are common.
The present invention, by picloram, fluroxypyr mixture, is detected it and made to the joint of weeds with different proportions
With i.e. indoor toxicity test, the results show that the weight ratio of picloram, fluroxypyr is in (1~25): (15~25)
Between, co-toxicity coefficient is all larger than 120, has apparent synergistic effect.
Herbicide of the present invention and each single dose have carried out wheat weeds controlling experiment, and following table three is the results show that in this hair
Under the premise of the bright herbicide effective ingredient consumption is less than or equal to each single dose effective ingredient consumption, the medicine of controlling weeds of the present invention
Effect is higher than each single dose, and following table two and table three show that each active constituent is without cross tolerance, control efficiency in herbicide of the present invention
With synergistic effect.

, dispersion stabilization is unqualified in embodiment 8.
Layering, livering observation
In order to further appreciate that the dispersible oil-suspending agent of picloram and fluroxypyr of the invention, in wheat
Tanaka is to the synergy in weeds.Fresh weight synergy raw test has been done to wheat paddock wild avena sativa with example 1-8 below.
Using the picloram (A) and fluroxypyr (B) preparation in embodiment 1-6 and comparative example 1-2, it is measured
To the co-toxicity coefficient of herba digitariae.Test method: by the seed of quantitative wild avena sativa be seeded in respectively bore 8cm, depth 7cm it is disposable
In basin alms bowl, 10~15 seeds are sowed in every basin, are cultivated in weather culturing room, when 3~4 leaf phase of wild avena sativa and amur foxtail,
Spraying treatment is carried out on walking spray tower.Weather culturing room continues to cultivate after processing, and routine observation is respectively handled to weeds
Preventive effect, weighs that each treated that weeds fresh weight is calculated its virulence and returned by the method that the nineteen sixties such as Sun Yunpei propose after 30d
Return curve and co-toxicity coefficient.Co-toxicity coefficient is greater than 120, shows that two kinds of active principles have synergistic effect, co-toxicity coefficient is in 80-
