Description
Technical field
The present invention relates to a kind of weeding class composition pesticide, particularly for Soybean Field, sugarcane field, corn field, Rapeseed Field,
The farmlands such as tea place and bare place weeding..
Background technology
The farmlands such as Soybean Field, sugarcane field, corn field, Rapeseed Field, tea place and bare place weeding have numerous weeds.With common
Exemplified by soybean weedses, soybean weedses can be divided into three major types in the sense that preventing and kill off, i.e. annual gramineous weed, annual
Broad leaved weed and perennial weeds.Soybean Field annual gramineous weed mainly has barnyard grass, green bristlegrass, setaria glauca, wild broomcorn millet, horse
Tang, wild oat etc..Soybean Field annual broadleaf weed mainly has Amaranthus retroflexus, Siberian cocklebur, black nightshade（Black star）, acalypha copperleaf, lamb's-quarters（Ash
Dish）, bog marshcress herb, piemarker, water spine pin, willow leaf thorn smartweed, chickweed, wolf tail grass（Ghost fork）, salsola collina, elscholtiza（Wild perillaseed）, purslane,
Pale persicaria, dayflower（Orchid dish）, Semen Cuscutae etc..Soybean Field perennial weeds mainly has sowthistle, meadow pine（Save bone grass）, it is small
Ji（Field thistle）, setose thistle（Cottonsedge-like thistle herb）, reed, alkali grass etc..From in recent years, one kind is all presented in most of China area
The broad leaved weed such as trend, dayflower, wolf tail grass, pale persicaria, Siberian cocklebur, black nightshade, bog marshcress herb, piemarker, sowthistle, field thistle, setose thistle
It gradually instead of the grassy weeds such as barnyard grass, wild oat, green bristlegrass and turn into Soybean Field main weeds.Field thistle, sowthistle, duck
Plantar grass is more known as Soybean Field " three dishes ", turns into the difficult point that soybean weedses are prevented and kill off.Soybean Field chemical herbicide occupation mode,
Typically take before broadcasting or broadcast rear before seedling soil treatment and after seedling cauline leaf process two ways.Before broadcasting or broadcast rear before seedling soil treatment
Before advantage is management of weeds in the budding period and damaged, herbicidal effect is more stable, and dispenser cost is relatively low, even if anti-
Cut weeds bad compared with fruit, after seedling can also be remedied.Shortcoming：When pH value, had a great influence by soil types, the content of organic matter,
Soil excessively glues to be not suitable for using soil treatment when weight, the content of organic matter are too high or pH value does not meet certain medicament；Second, some
Herbicide such as metribuzin, 2,4-D butyl esters etc. are also easy to produce poisoning due to the leaching of medicament in sand soil, low-lying land；Third, by meteorology
Condition has a great influence, and particularly spring arid, wind is big and abnormal low temperature or high temperature can all influence herbicidal effect.After seedling cauline leaf process
The advantages of be influenceed by soil types, the content of organic matter, soil moisture it is smaller, can be suitable according to weeds species selection of being unearthed
Herbicide with strong points.Shortcoming：When in drought, air humidity is small and weed growth it is slow in the case of weeding imitate
Fruit is bad；Second, some medicaments are also easy to produce poisoning under the conditions of too high or too low for temperature；Third, after seedling cauline leaf process must be big
Most weeds are unearthed and could carried out when having the leaf area of certain adhering liquid medicine, and now soybean early growth is by crop smothering shadow
Ring, cause the underproduction.Therefore, Soybean Field chemical weed control is typically based on soil treatment, supplemented by after seedling cauline leaf process.To weeds species
Plot more, that radix is larger needs to carry out secondary chemical weed control.Therefore Soybean Field chemical weed control, will flexibly be slapped in implementation process
Hold, particular problem concrete analysis.Because soil property difference in all parts of the country is larger, and climate difference is notable, adds Soybean Field weeding
Difficulty.
Corn field common weed has barnyard grass, lady's-grass, piemarker, Amaranthus retroflexus, eleusine indica, india lovegrass, green green bristlegrass, setaria glauca
Etc..Sugarcane field common weed has the annual grassy weeds such as the rhizome of nutgrass flatsedge, lady's-grass, eleusine indica, bald barnyard, bidens pilosa, Bermuda grass.
Not only raw weeds also have perennial weeds one year in corn field common weed, and these weeds have multiple out of grass, preventing and treating
Difficulty is big.Poisoning easily occurs for glyphosate most-often used in agricultural production, glufosinate-ammonium, Acetochlor, Bi Kecao etc. at present.It is simultaneously big
High is required to the careless age of weeds during the foregoing Common Herbicides dispenser in part, beyond a range of careless age, herbicidal effect substantially drops
It is low.Glyphosate, glufosinate-ammonium class herbicide are more only applicable to bare place weeding.Meanwhile weeds will produce not to chemical herbicide
With the resistance of degree.These factors, all causing herbicide to need constantly to release, effect is more preferable, the wider array of new varieties of herbicide controlling spectrum.

Active ingredient particle diameter is ground at 2~5 μm.
By following experiment it can be shown that two active ingredient TAM-5 and fluorine thiophene are careless in the above-mentioned Herbicidal combinations of the present invention
The compounding of amine can have obvious synergistic effect.
In the research of herbicide, activity of weeding after active compound is administered alone more than each reactive compound
Activity when, then show synergistic effect be present.
The budget activity of the given combination of two kinds of herbicides can be calculated as follows（Bibliography：Author Colby, S.R. etc.,
Periodical title《Weed》, 1 phase in 1967, P20-22）
When X=% amount of application be p kg/ha in the case of, herbicide A (reactive compound A) loss ratio,
And Y=% amount of application be q kg/ha in the case of, herbicide B (reactive compound B) loss ratio,
And E=% amount of application be p and q kg/ha in the case of, herbicide A and B speculative damage rate, then：
E=X+Y-X*Y/100
If actual damage value exceedes calculated value, the activity of composition is super plus sum, that is, shows synergy.
