Description

One kind humulone containing quinoline and sethoxydim binary herbicidal composition and its preparation and application
Technical field
The invention belongs to pesticide herbicide technical fields, and in particular to one kind humulone containing quinoline and sethoxydim binary herbicide group Close object 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.
Sethoxydim belongs to oxime herbicide, is mitotic inhibitor, almost has high activity to all gramineae weeds, right Broadleaf weeds is invalid and safe.Sethoxydim is the very strong inner sucting conduction type cauline leaf process agent of selectivity, can be by gramineae weed stem Leaf absorbs rapidly, and is transmitted to top and internode separate living tissue, destroys cell division lethal.It can be used for soybean, cotton, oil Barnyard grass, wild avena sativa, herba setariae viridis, amur foxtail, horse are prevented and kill off in the crops such as dish, peanut, potato, beet, sunflower, flax and orchard Tang, herba eleusines indicae etc., it is invalid to broadleaf weeds.
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.
Herbicidal effect is used alone in the weeds that sethoxydim, quinoline humulone have oneself distinctive herbicidal spectrum and cannot prevent and kill off It 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.
