Description
Technical field
The invention belongs to pesticide herbicide technical fields, and in particular to a kind of binary weeding of humulone containing quinoline and flucarbazone
Agent composition and its preparation and application.
Background technique
Wheat is one of China's Three major grain crops, and cultivated area and total output are only second to rice, national cultivated area
Up to more than 3,000 ten thousand hectares, about 4.5 hundred million mu, the 22%-30% of national cultivated area, the about 20%- of cereal crops sown area are accounted for
27%, about 100,000,000 tons of wheat total output, reach 22%(Wu Ming honor of total output of grain etc., 2013, pesticide).Wheat is that China is main
Commodity food and strategic reserves grain kind, in grain-production, circulation and consumption have critical role, develop Wheat Production to me
State's national economic development and people's lives are of great significance.
But the weeds of wheat paddock have great threat to Wheat Production.According to national weeds reconnaissance information, China wheat
Field weed type has more than 200 kinds, and crop smothering area accounts for 30% or more of wheat planting area, and loss accounts for about wheat total output
15%.Therefore wheat weeds prevention and treatment is one of important process of wheat planting.
Herbicide is the common measure of current wheat weeds prevention and treatment, promotion wheat yield is improved and saved planting cost tool
There is important role.But herbicide it is long-term, be widely applied, make farmland weed chemical control there are Weed Resistance,
Population succession and drug injury problem are on the rise, and seriously affect high yield and safety (Wei Youhai, the lake of good harvest and succession crop of wheat
Northern agricultural sciences, 2011.4).Long-time service single herbicide, which is prevented and kill off, will lead to the decline of susceptible weeds quantity, insensitive or evil
Property weeds quantity rise, cause weed community to change, seriously affected the harvest of wheat crop yield.
Flucarbazone is sulfonylurea internal-suction type high-efficiency wheat field herbicide, to grass family such as wild avena sativa, herba bromi japonici, amur foxtails
Weeds and a variety of broadleaf weeds have obvious preventive effect.Flucarbazone, is a kind of novel compounds, and effective component can be by weeds
Root and cauline leaf absorb, and by inhibiting the activity of acetolactate synthestase in weeds body, destroy the normal Physiological and Biochemical Metabolism of weeds
And play activity of weeding.Flucarbazone can effectively prevent and kill off wheat paddock major part gramineae weed, while part also can be effectively controlled
Broadleaf weeds.Flucarbazone can be metabolized quickly in wheat, have fabulous safety to wheat.
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
Wheatland major part broadleaf weeds, but it is poor to grassy weed effect.
Weeding effect is used alone in the weeds that flucarbazone, quinoline humulone have oneself distinctive herbicidal spectrum and cannot prevent and kill off
Fruit 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.
