Description
Technical field
The invention belongs to pesticide herbicide technical fields, and in particular to one kind humulone containing quinoline and fenoxapropPethyl binary are removed
Careless agent composition and its preparation and application.
Background technique
Soybean is annual herb plant, is most important beans in the world.Since its nutritive value is very high, referred to as
" king in beans ", " meat of Tanaka ", " green cow's milk " etc. are the foods most praised highly by nutritionist in hundreds of natural foods
Object.Weeding before seedling, most common spectrum herbicide has Pu Shite and clomazone in production, both herbicides are to Soybean Field
A variety of dogstail sections weeds and broadleaf weeds are all effective.When Pu Shite, chlorimuron- ethyl, clomazone can retain longer in the soil
Between, to pay special attention to the phytotoxicity to succession crop.Postemergence weed control, the herbicide that emergence early stage is applicable in, at present using most in production
Generally Pu Shite.It is administered when weeds are just unearthed, is generally not later than 2 compound leaf phases of soybean.The emergence later period can use capture
Net emulsion, smart quizalofopethyl missible oil, gram wealthy happy missible oil.
Sunflower is the annual herb plant of asteraceae helianthus.Its seed has more economic value, can not only be made
By the favorite sunflower seed of people, the advanced edible sunflower oil for the low cholesterol that can more squeeze out.It is suitable to apply field benefit, smart quizalofopethyl and the happy logical category of receipts
In the herbicide that sunflower uses, normal use dosage is only received pleasure and is led to after application 3 days, and sunflower cotyledon generates contact medicine
Evil spot, but restore normal growth quickly；After application 7 days, young leaves growth is normal.Field is applied to mend with smart quizalofopethyl to sunflower without obvious
Symptom of chemical damage.Using above-mentioned 3 kinds of herbicides, sunflower normal growth and can blossom and bear fruit.Benefit is received and Acetochlor uses normally
Dosage can make sunflower generate phytotoxicity, but influence unobvious.After benefit receives application 1 day, sunflower blade generates contact calcination type
Phytotoxicity spot, phytotoxicity spot switchs to sepia and dries up shape in the 4th day old leaf, also generates phytotoxicity spot after tender leaf expansion, lobus cardiacus shrinkage, but new
Leave growth is normal.Acetochlor develops slower, lobus cardiacus shrinkage after application 7 days to sunflower phytotoxicity, vein in reeling off raw silk from cocoons shape, blade tip to
It inside shrinks, young leaves growth is also influenced without phytotoxicity.
Weeds have great threat to soybean and sunflower production.Herbicide is the common measure of current control of weeds,
Promotion output increased and saving planting cost are played an important role.But long-term, the large scale application of herbicide, make
There are Weed Resistance, population succession and drug injury problems to be on the rise for farmland weed chemical control, seriously affect the high yield of crop with
The safety of good harvest and succession crop.Be used for a long time single herbicide prevent and kill off will lead to susceptible weeds quantity decline, it is insensitive or
Malignant weed quantity rises, and causes weed community to change, has seriously affected crop yield.
FenoxapropPethyl belongs to heterocyclic oxy group phenoxy propionic acid class herbicide, mainly by inhibiting fatty acid synthesis
Key enzyme --- acetyl-CoA carboxylase, to inhibit the synthesis of fatty acid.Medicament is by cauline leaf Assimilation and conductivity to mitogenetic group
It knits and the growing point of root, effect rapidly, stops growing for 2-3 days after application, 5-6 days lobus cardiacus chlorosis purpling colors, separate living tissue browning
Color, blade is gradually withered, is the extremely strong cauline leaf process agent of selectivity.It is mainly used for Control Wild oat, amur foxtail, herba setariae viridis, swallow
Wheat, rye grass, annual bluegrass, barnyard grass, spontaneous corn, herba digitariae etc..Suitable for dicotyledonous crops such as soybean, peanut, rape, cotton, sweet tea
The Tanakas such as dish, flax, potato, vegetable fields and sorosis garden prevent and kill off monocotyledon weed.It is added after safener Hoe070542 suitable for small
Wheatland prevents and kill off gramineae weed.
Quinoline humulone is the new compound developed recently, is hydroxyphenyl pyravate dual oxide enzyme (HPPD) inhibitor, interference
The synthesis and function of chloroplaset.After cauline leaf absorbs, conducts up and down, make weeds cauline leaf albefaction, growth is suppressed, usual weeds 7
It is dead after it.Efficient activity of weeding, good quick-acting are shown to a variety of broadleaf weeds and gramineae weed, can be prevented and kill off big
Part broadleaf weeds, but it is poor to grassy weed effect.
The weeds that fenoxapropPethyl, quinoline humulone have oneself distinctive herbicidal spectrum and cannot prevent and kill off, exclusive use remove
Careless effect is less desirable.
Exploitation new product herbicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
With investing, small, the lead time is short with mixture for compounding.Reasonable chemical herbicide compounding or mixture, which have, expands degrass spectrum, improves
Control efficiency extends application period, reduces dosage, reduce phytotoxicity risk, reduce residual, delay weeds drug resistance and drug resistance
Generation and development the advantages that, so selecting suitable mixture of herbicides or mixture is solve the above problems maximally efficient and warp
One of method of Ji；However because the mechanism of action is complicated between mixed pesticide, after combination whether shadow of the synergy by many factors
It rings, only dependence experimental result is verified, and can not be expected.
