Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Herbicidal combinations containing diuron and flumioxazin.
Background technology
Diuron (diuron), chemical name 3-(3,4-dichlorophenyl)-1,1-dimethyl urea, phenyl ureagroup herbicides, have Uptake and translocation effect and certain action of contace poison.Inhibited photosynthesis after medicament is absorbed by root system of plant or blade, cause leaf chlorosis, blade tip and edge fade, and cause plant for want of nutrition and dead.Be mainly used in the crops such as cotton, soybean, tomato, tobacco, strawberry, grape, orchard, rubber plantation and prevent and kill off annual gramineous weed and some broad leaved weed, as non-irrigated barnyard grass, lady's-grass, green foxtail, wild amaranth grass, nutgrass flatsedge, lamb's-quarters etc., also rice field pondweed, four leaf duckweeds can be prevented and kill off, fescue etc.Its chemical structural formula is:
。
Flumioxazin (flumioxazin), chemical name is N-(7-fluoro-3,4-dihydro-3-oxygen-(2-propynyl)-2H-1,4-benzimidazole dihydrochloride-6-base) hexamethylene-1-alkene-1,2-dicarboximide, study on mechanism finds, builds up in the body of sensitive plant with protoporphyrin after flumioxazin process, result in the peroxidating of photosensitization and Cell membrane lipids, which results in cell membrane function and the irreversible destruction of structure.Large Tanaka, after cauline leaf process, the cauline leaf of susceptible weeds is downright bad, dead after solar radiation; After soil treatment, the bud of susceptible weeds is downright bad, dead after of short duration solar radiation.The water tawny daylily fiber crops of the Tanaka such as control cotton, soybean, peanut, apple, oranges and tangerines, grape, pears of flumioxazin Absorbable organic halogens, lamb's-quarters, summer cypress, thorn bud fruit, carpet weed, coffee senna, mother chrysanthemum, Mao Mulan, datura, lead a cow, sandlwood, black nightshade, black eggplant, the weeds such as kitchen garden, especially there is favorable effect to broad leaved weed, and to the weeds that the ALS inhibitor such as triazines inhibitor of photosynthesis, sulfonylurea, sulfonanilide and imidazolone type develop immunity to drugs, there is good control efficiency.Its chemical structural formula is:
。
The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing, and therefore, their herbicide ability and scope are also different.Due in current agricultural production when single active ingredient weed killer herbicide use time, affect by factors such as resistances, weeds eradicate effect can greatly reduce.If formulate the former drug compound of novel weed killer herbicide, the initiative cycle of noval chemical compound is longer, drops into huge, and current domestic agricultural chemicals enterprise limit by scale, research strength, and it is unpractical for carrying out creative research to former drug compound.And composite between agricultural chemicals can solve, and agricultural chemicals single dose toxicity is large, the problem of weak effect, less investment again, R&D cycle are short, meet the present situation of domestic agricultural chemicals enterprise, and the mutual use between different agricultural chemicals can the drug-fast generation of retarding action thing, have ideal result of use, therefore between the different mechanism of action, agricultural chemicals composite is the study hotspot of current pesticide field.And flumioxazin is a kind of novel N-phenyl faces amine carboximide class weed killer herbicide, the mode of action is comparatively unique, and does not have cross resistance with other weed killer herbicides on domestic market, producing, extending its market cycle to delay weeds to the resistance of diuron.My company research staff attempt by diuron and flumioxazin composite, whether there is synergistic effect to observe it, and reduce its use cost.Through the checking of a large amount of indoor biometrics and field experiment; find with diuron and flumioxazin for active ingredient carry out composite after; weed eradication rate improves greatly; quick-acting is obviously strengthened, and also there is certain prolongation the lasting period, and dosage is lower; reduce agricultural cost; toxicity is less, and residual quantity is less, advantageously in environmental protection.Experiment has very strong synergistic effect both confirming, and can relevant diuron be that active component carries out composite research with flumioxazin, there is not yet relevant report at home and abroad at present.

indoor virulence test and field experiment.
indoor virulence measuring.
1, joint toxicity measuring
Test site: test in Laiyang Shandong Province corn trials field.
Subjects: corn field weed---barnyard grass and kitchen garden.
Test medicine: 18% diuron flumioxazin ratio of weight and number is respectively 13:5,11:7,9:9,7:11,5:13, totally 5 mixture combinations.
Assay method: field trial method.In barnyard grass and kitchen garden 2-5 leaf after date phase cauline leaf spraying process; The spraying amount of being watered 750 liters/hectare, measures weeds fresh weight of living in after dispenser 10 days, often processes five times and repeat, and adopts Col diuron y method to judge synergy type.
Col diuron y law theory preventive effect computing formula is:
E
0＝XY/100；
E in formula
0for single dose flumioxazin mixed with diuron after theoretical preventive effect; X is weed killer herbicide flumioxazin weeds weight under certain dosage is the percentage contrasting weeds weight; Y is herbicide Dailon weeds weight under certain dosage is the percentage contrasting weeds weight; If the weeds weight that E is flumioxazin, rear actual measurement used with by diuron is the percentage of contrast weeds weight.
If E is significantly less than E
0, be then synergistic effect; E and E
0, close, be then summation action; E is obviously greater than E
0, be then antagonism.
Result of the test:
Table 1 diuron and flumioxazin composite to corn barnyard grass, kitchen garden joint toxicity measuring
Virulence test example shows, diuron differs more than 10% with the measured value of flumioxazin with theoretical value, there is obvious gap, both are composite has notable synergistic effect, and synergistic effect is the most obvious when in the formulation of 18%, the ratio of weight and number of diuron and flumioxazin is 13:5 and 11:7, suggestion does further field experiment in this scope, better to evaluate its synergistic effect.
