Description
Technical field
The present invention relates to a kind of weeding class composition pesticides, especially for wheat paddock, sugarcane field, corn field, Rapeseed Field,
The farmlands such as tea place and bare place weeding.
Background technique
China is one of yield wheat big country, the world, and wheat yield is sure to occupy the first in the world for many years.However China's weeds of wheat
It is numerous, it is easy to influence wheat yield and quality.The main weeds of wheat paddock have Descurainia sophia, barnyard grass, wild avena sativa, willow leaf thorn smartweed, acid
Mould leaf knotweed, volume stem smartweed, Chenopodiaceae, Amaranthus retroflexus, Siberian cocklebur, bur beggar-ticks, dayflower, weasel hemp nettle, artemisia, sowthistle, field thistle, setose thistle, acid
Mould etc..China's wheat field herbicide passes through years of researches, has had very more kinds to occur, has mainly had: 69g/L essence oxazole
Diclofop-methyl EW, 69 grams per liter fenoxapropPethyls+safener, 3% mesosulfuron WP, 3.6% iodosulfuron-methyl-sodium methyl two
The grand WDG(0.6:3 of sulphur), the grand WDG(5:1.25 of the phonetic methiodide of 6.25% acyl), 70% flucarbazone WDG, 75% tribenuron-methyl DF, 50 grams/
Rise pinoxaden alkynes oxalic acid EC(2.5:2.5), 480 grams per liter dicamba AS, 15% alkynes oxalic acid WP, 20% fluroxypyr
EC, 58g/ rise double phonetic sulphur SC(25:33 of fluorine azoles), 559g/ rise florasulam 2,4-D isobutyl ester SC(0.6:45.3), 7.5%
Pyroxsulam WDG, the different monooctyl ester SC of 43% florasulam dimethyl tetrachloride, 15% couple of fluorine fluroxypyr SC(0.5:14.5).
China is one of Chan Mian big country, the world, wherein with provinces and regions such as Shandong, Ji, Henan, Soviet Union, Hubei Province, new, Anhui for main cotton growing area.
Weed in cotton field mainly has 24 sections about more than 60, wherein with the herba digitariae in gramineae weed, herba eleusines indicae, semen euphorbiae, non-irrigated barnyard grass, dog tail
It is maximum that density occurs for grass, Paspalum distichum, Bermuda grass etc.；Broadleaf weeds is with Eclipta prostrata, Amaranthus retroflexus, argy wormwood, chenopodium glaucum linn, Acalypha-austratis-L, piemarker
Based on fiber crops etc.；Sedge weed is based on the rhizome of nutgrass flatsedge.In Yellow River basin cotton region, with the rise of temperature, cotton field after sowing cotton seed
A variety of weeds start rudiment successively, until mid or late May forms first emergence peak in field, at this time with herba setariae viridis, herba digitariae, drought
Based on barnyard grass, Chenopodiaceae etc., with rainfall and pour water later it may also occur that primary small germination peak；To July, with the arrival in rainy season,
The weeds such as the rhizome of nutgrass flatsedge are largely unearthed, and second germination peak is formed, and at the same time, the weeds that early period is unearthed enter growth most flower
Phase, thus easily cotton is caused seriously to cause harm.China cotton field is widely distributed, and different cotton region weed communities and dominant population are not
Together.Yangtze river basin cotton region has a moderate climate with heavy rainfall, is suitable for weed growth, and dominant weed is with herba digitariae, herba eleusines indicae and the rhizome of nutgrass flatsedge
It is main.To like to form various weed communities based on cool resistance to early weeds, common weed mainly has herba digitariae, Bermuda grass, dish etc. for North china
It is a variety of.Since the herbicide kind of single type is used for a long time, the variation of farmland weed population and the succession of community accelerate, certain secondary
Weeds are increasingly becoming main weeds, and intractable weed harm is got worse, and increase chemical weed control difficulty.The chemical weed control of China cotton field
There are the problem of be that method of administration is improper first.The distribution of China cotton field is wide, after the generation of planted in different ecological areas weeds and spraying herbicide
Primary and secondary wants the succession of herbaceous of weeds still to lack further investigation, not formed targetedly to prevent and kill off the section's general education being formulated to numerous cotton growers
Educate deficiency, the not perfectly flat weighing apparatus of various regions application technology level, because selecting medicament and administration time, dosage method etc. no in practice
When often resulting in phytotoxicity.The chemical weed control of China cotton field starting late, fundamental research is weaker, cotton field chemical weed control kind compared with
It is few, it carries out in a deep going way and more effectively applies there is an urgent need to research.These factors all make cotton field herbicide need constantly to release
Effect is more preferable, the wider array of new varieties of degrass spectrum.
In addition, the farmlands such as Soybean Field, sugarcane field, corn field, Rapeseed Field, tea place and bare place weeding equally have it is numerous miscellaneous
Grass.By taking common soybean weeds as an example, soybean weeds can be divided into three categories in the sense that preventing and kill off, i.e. annual gramineae
Weeds, annual broadleaf weed and perennial weeds.Soybean Field annual gramineous weed mainly has barnyard grass, herba setariae viridis, golden dog
Tail grass, wild broomcorn millet, herba digitariae, wild avena sativa etc..Soybean Field annual broadleaf weed mainly has Amaranthus retroflexus, Siberian cocklebur, black nightshade (black star), iron
Three-coloured amaranth, Chenopodiaceae (Chenopodium album), bog marshcress herb, piemarker, water spine pin, willow leaf thorn smartweed, herba stellariae mediae, wolf tail grass (ghost fork), salsola collina, elscholtiza (open country Soviet Union
Son), purslane, pale persicaria, dayflower (orchid dish), Semen Cuscutae etc..Soybean Field perennial weeds mainly has sowthistle, meadow pine
(section bone grass), field thistle (field thistle), setose thistle (cottonsedge-like thistle herb), reed, alkali grass etc..From in recent years, in most of China
Area is all presented a kind of trend, dayflower, wolf tail grass, pale persicaria, Siberian cocklebur, black nightshade, bog marshcress herb, piemarker, sowthistle, field thistle, big
The broadleaf weeds such as Ji have gradually replaced the gramineae weeds such as barnyard grass, wild avena sativa, herba setariae viridis and have become Soybean Field main weeds.It is small
Ji, sowthistle, dayflower are more known as Soybean Field " three dishes ", become the difficult point that soybean weeds are prevented and kill off.Soybean Field chemistry removes
Careless agent usage mode is generally taken and broadcasts preceding or soil treatment before seedling sowing and stem and leaf treatment after seedling two ways.Before broadcasting or after broadcasting
It is management of weeds the advantages of soil treatment before seedling in the budding period and before causing damages, herbicidal effect is more stable, dispenser cost
It is relatively low, even if management of weeds is bad compared with fruit, can also be remedied after seedling.Disadvantage: first is that pH value, by soil types, organic
Matter content is affected, and is not suitable for when soil excessively glues weight, the content of organic matter is excessively high or pH value does not meet certain medicament using soil
Earth processing；Second is that some herbicides such as metribuzin, 2,4-D butyl ester etc. are also easy to produce in sand soil, low-lying land due to the leaching of medicament
Phytotoxicity；Third is that be affected by meteorological condition, especially spring arid, wind is big and abnormal low temperature or high temperature can all influence weeding effect
Fruit.The advantages of stem and leaf treatment after seedling be influenced by soil types, the content of organic matter, soil moisture it is smaller, can be according to being unearthed
The suitable herbicide with strong points of weeds type selection.Disadvantage: first is that in drought, air humidity is small and weed growth is slow
Herbicidal effect is bad in the case where slow；Second is that some medicaments are also easy to produce phytotoxicity under the conditions of too high or too low for temperature；Third is that after seedling
Cauline leaf process must just can be carried out when most of weeds are unearthed and have the leaf area of certain adhering liquid medicine, at this time soybean early period
Growth is influenced by crop smothering, causes the underproduction.Therefore, Soybean Field chemical weed control is generally based on soil treatment, after seedling at cauline leaf
Supplemented by reason., radix biggish plot more to weeds type needs to carry out secondary chemical weed control.Therefore Soybean Field chemical weed control, In
It flexibly to be grasped in implementation process, particular problem concrete analysis.Due to, soil property difference in all parts of the country is larger, and climate difference is significant,
Increase the difficulty of soybean field weeding.
Soybean Field common weed is just like three-coloured amaranth, knotweed, Chenopodiaceae, black nightshade, Siberian cocklebur, barnyard grass, herba setariae viridis, herba digitariae, broomcorn millet etc..Sugarcane field is normal
See that weeds there are the annual grassy weeds such as the rhizome of nutgrass flatsedge, herba digitariae, herba eleusines indicae, bald barnyard, bidens pilosa, Bermuda grass.Corn field is common miscellaneous
Not only there are also perennial weeds for raw weeds one year in grass, but also these weeds have multiple out of grass, and difficulty of prevention and cure is big.Agriculture at present
Phytotoxicity easily occurs for most-often used glyphosate, glufosinate-ammonium, Acetochlor, Bi Kecao etc. in industry production.It is most of simultaneously aforementioned common
Height is required to the careless age of weeds when herbicide is administered, beyond a certain range of careless age, herbicidal effect is substantially reduced.Glyphosate, grass
Ammonium phosphine herbicide is more only applicable to bare place weeding.Meanwhile weeds will generate different degrees of resistance to chemical herbicide.
These factors, all making herbicide need constantly to release, effect is more preferable, the wider array of new varieties of degrass spectrum.
