Abstract
The invention discloses a kind of Herbicidal combinations containing furans sulphur humulone and penoxsuam and sulfonylurea herbicide, active ingredient is made of furans sulphur humulone, penoxsuam and sulfonylurea herbicide, the one kind of sulfonylurea herbicide in halosulfuronmethyl, pyrazosulfuron, orthosulfamuron, bensulfuron-methyl, promazine Sulfometuron Methyl, piperazine pyrazosulfuron, furans sulphur humulone, penoxsuam and the weight ratio of sulfonylurea herbicide three are 0.5~50:5:0.5~50.Herbicidal combinations provided by the invention are applied to preventing and kill off for paddy field weed, are used alone with each single dose or mutually significantly improve herbicidal effect compared with binary built use, expand herbicidal spectrum, the lasting period is long, to rice safety.
Description
Technical field
The present invention relates to composition pesticide and its application fields, and specifically one kind is with furans sulphur humulone, penoxsulam
Amine and the Herbicidal combinations that sulfonylurea herbicide is effective active composition ternary built, are mainly used in the anti-of paddy field weed
It removes.
Background technology
Furans sulphur humulone (tefuryltrione)：Belong to benzoylcyclohexan dione herbicides, the mechanism of action is 4- hydroxyls
Base phenylpyruvic acid dual oxide enzyme inhibitor, can inhibit pigment synthesis indispensable in plant growth, by root, stem, young shoot,
Leaf is absorbed and is conducted rapidly.Furans sulphur humulone can be used for rice terrace and prevent and kill off annual and perennial broadleaf weed, and before or after buds are equal
It can be used, it is broken to annual broadleaf weeds, the awns such as firefly Lin, Herba Cyperi Glomerati such as Monochoria vaginalis, Procumbent Falsepimpernel, Monochoria korsakowii, rhizoma alismatis, auricle water amaranths
Rice Cyperus weeds and the broad leaved weeds such as the short arrowhead of resistance, angustifolia arrowhead herb, water chestnut are generated to sulfonylurea in recent years has and extremely have
Effect.In addition, having to the paddy land weeds such as the special weeds such as triquetrousc murdannia herb, ambatch, sweet wine intestines, bur beggar-ticks, big bur beggar-ticks and fake rice, Rong's grass
Extensive preventive effect.
Penoxsuam (penoxsulam)：Belong to triazolopyrimidine sulfonamides herbicide, medicament through cauline leaf, young shoot and
Root system absorbs, and can rapidly be adsorbed by soil.It is conducted to separate living tissue by xylem and bast, inhibits plant strain growth, make life
Long point chlorosis, 7~14d terminal buds redden after processing, necrosis, and plant is dead within 2~4 weeks.This agent inhibits for strong acetolactate synthestase
Agent, medicament presentation is slower, needs certain time weeds just gradually dead.Rice field broad-spectrum herbicide can effectively prevent and kill off barnyard grass and one
Year life sedge weed, and it is effective to numerous broad leaved weeds, such as the different stamen flower of natural pond life, carp intestines, sesbania, ring flower, Monochoria vaginalis；Also
Rice field moderate resistance bensulfuron-methyl weeds can be prevented and kill off, and there is residual activity to many broad-leaveds, sedge weed and barnyard grass etc..
Sulfonylurea herbicide is a kind of herbicide that kind is most, application range is most wide in the world, with high activity, extensively
Spectrum, low dosage, low toxicity, it is highly selective the advantages that.Sulfonylurea herbicide passes through to the acetolactate synthestase in plant
Inhibit, to hinder branched-chain amino acid biosynthesis, inhibits the division and growth of plant cell.Halosulfuronmethyl
(halosulfuron-methyl), pyrazosulfuron (pyrazosulfuron-ethyl), orthosulfamuron
(orthosulfamuron), bensulfuron-methyl (bensulfuron-methyl), promazine Sulfometuron Methyl (propyrisulfuron), piperazine
Pyrazosulfuron (metazosulfuron) is the sulfonylurea herbicide being commercialized, and is widely used in the anti-of weeds in farmland
It removes.
The use of chemical agent weeding is agriculturally to control one of the main means of weeds in field.However in recent years, due to one
The large area of a little herbicide kinds is individually used continuously, and already leads to many weeds and produces drug resistance；Simultaneously as field is miscellaneous
Mutually complexity, type are various for grass when grass occurs, single if grassy weed, sedge weed and broad leaved weed often mix generation
Herbicide kind or two-spot be used in compounding and can not effectively solve the above problems, can show defect in a certain respect.
By the screening of a variety of different mixture of herbicides formulas, rational formula is filtered out, can be effectively improved to weeds
Practical control effect expands herbicide controlling spectrum, reduces dosage, reduces cost, mitigates the pollution to environment, delays herbicide resistance
It generates, extends the Pesticide use service life, be the important means of agriculturally weeds comprehensive treatment.
The present inventor is in further investigation furans sulphur humulone, penoxsuam and sulfonylurea herbicide ternary built formula
In the process, surprisingly furans sulphur humulone, penoxsuam and sulfonylurea herbicide carry out ternary built, certain
Compound proportion within the scope of significant collaboration is all had to a variety of grassy weeds, sedge weed and the broad leaved weed of rice terrace
Synergistic effect completes the present invention after further study.
Invention content
The purpose of the present invention is to provide a kind of component is reasonable, obvious synergy, herbicidal effect protrudes, herbicidal spectrum
Extensively, the lasting period is long, and drug cost is low, weeds can be delayed to develop immunity to drugs, and to the ternary built Herbicidal combinations of rice safety.
Another object of the present invention is to provide one kind to remove containing furans sulphur humulone and penoxsuam and sulfonylurea
The preparation formulation of the Herbicidal combinations of careless agent.
It is still another object of the present invention to provide purposes of the above-mentioned Herbicidal combinations in preventing and kill off paddy field weed.
Technical scheme of the present invention：To achieve the above object, present invention offer is a kind of containing furans sulphur humulone and five fluorine sulphurs

Synergistic and Antagonistic Responses of Herbicide combinations”(Weeds 15/1
(1967), S.R.Colby) described in Colby ' s methods determine, as follows：
In formula：
A be when using the reactive compound A that dosage is mg/ha or a concentration of mppm, survival rate to target weeds or
Fresh weight survival rate (%)；
B be when using the reactive compound B that dosage is ng/ha or a concentration of nppm, survival rate to target weeds or
Fresh weight survival rate (%)；
C be when using the reactive compound C that dosage is hg/ha or a concentration of hppm, survival rate to target weeds or
Fresh weight survival rate (%)；
N is the herbicidal active component kind number of mixture；
E0It is to work as to use dosage for m, it is right when the reactive compound A, B and C of n, hg/ha or a concentration of m, n, hppm are mixed
The theoretical value of target weeds survival rate or fresh weight survival rate (%)；
It is m that E, which is when using dosage, when the reactive compound A, B and C of n, hg/ha or a concentration of m, n, hppm are mixed, to target
Mark weeds survival rate or the observation of fresh weight survival rate (%)；
If the target weeds survival rate or fresh weight survival rate of actual observation are less than theoretical target weeds survival rate or fresh weight
Survival rate has the effect of unexpected then the composition shows to act synergistically.
