Description
Technical field
The invention belongs to pesticide herbicide technical fields, and in particular to a kind of binary herbicide of humulone containing quinoline and tribenuron-methyl
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.Weeds of wheat can be divided into broadleaf weeds and standing grain
Two class of undergraduate course weeds, is gradually aggravated although gramineae weed endangers in recent years, and broadleaf weeds is still in northern China wheat paddock
It has the advantage status, main species have Descurainia sophia, shepherd's purse, corn gromwell, conical silene herb, clearvers, Chenopodiaceae, small Chenopodiaceae, ivy glorybind, Tian Xuan
Spend, lead a cow, field thistle, pivot storage, piemarker, Siberian cocklebur, summer cypress, towards day potentilla chinensis, wallflower, humulus grass, Lepidium apetalum, Veronica, attached
Ground dish, wartwort etc..
Tribenuron-methyl is China for the most important herbicide kind of controlling broad leaved weed in wheat field, the few, toxicity with dosage
Low, broad weed-killing spectrum, to many merits such as crop safeties.Tribenuron-methyl, English common name tribenuron-methyl, chemical name
2- [4- methoxyl group -6- methyl-1,3,5- triazine -2- base (methyl) carbamoylamino sulfonyls] methyl benzoate, CAS are stepped on
Mark 101200-48-0.Lactofen, English common name lactofen, chemical name 2- nitro -5- (the chloro- 4- fluoroform of 2-
Phenoxyl) benzoic acid -1- (carbethoxyl group) ethyl ester, CAS registration number 77501-63-4.
However, with the extension of use time, herbicide resistance problem is generally sent out since tribenuron-methyl action site is single
Raw, tribenuron-methyl substantially reduces the preventive effect of weeds, and therefore, there is an urgent need to develop the synergistic compositions of tribenuron-methyl, to improve to miscellaneous
The control efficiency of grass extends the service life of this fine herbicide, ensures Wheat Production safety.
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, wheat can be prevented and kill off
Field major part broadleaf weeds, but it is poor to grassy weed effect.
Weeding effect is used alone in the weeds that tribenuron-methyl, 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.
