Description
Technical field
The present invention relates to weed killer herbicide field, specifically, relate to a kind of formamido group Sulfometuron Methyl and iodosulfuron-methyl-sodium compound herbicide.
Background technology
Formamido group Sulfometuron Methyl is a kind of sulfonylurea herbicide of efficient, wide spectrum, low toxicity, high selectivity, belongs to branched-chain amino acid synthetic inhibitor.Suppressing synthesising biological body essential amino acid, is cessation of cell division, hinders plant growth.Weeding after bud, is widely used in cereal as corn etc., all has excellent activity to many annual or perennial grass family or broad leaved weed.
Methyl iodide sulfonate sodium is selective post-emergence herbicide, be mainly used in cereal grassy weed and the broad leaved weeds such as control wheat, rye, barley, by weeds root, leaf absorb after, conduct in plant corpus, make weeds leaf look move back green, stop growing, then withered.Good preventive effect is had to annual broadleaf weeds such as clearvers, shepherd's purse, chickweed, wheat wormwood artemisias.Compare in weeds, cereal selectivity derives from and adds safener mefenpyrdiethyl, and cereal can be degraded this medicine, to cereal crop safety, on succession crop without impact, high with environment, ecological compatibility safety.
The weed killer herbicide of single-activity component, continuous administration weeds easily develop immunity to drugs, and herbicide spectrum is narrow, the many pollutions that also can increase the weight of environment of application times.As researched and developed the weed killer herbicide of new component, not only development cost is high, and the R&D cycle, does not also catch up with the speed that weeds produce resistance.And measure such as picture crop structure adjustment, different agricultural chemicals rotations etc., miss in process actual, have little effect.Therefore, the mixture of herbicides of heterogeneity, becomes the method that controlling weeds is the most frequently used.

Test dose designs: every medicament single dose is according to as follows to the respective featured configuration concentration testing weeds: formamido group Sulfometuron Methyl establishes 10,20,40,80g.a.i./ha (lady's-grass, barnyard grass); 12,24,48,96g.a.i./ha (acalypha copperleaf, kitchen garden), methyl iodide sulphur is grand establishes 5,10,20,40g.a.i./ha (lady's-grass, barnyard grass); 4,8,16,32g.a.i./ha (acalypha copperleaf, kitchen garden); Each medicament variable concentrations uses to obtain different blended dosing with between two.Concrete experimental scheme dosage is in table 4 and table 5.
Table 4 reagent agent prevents and kill off lady's-grass, barnyard grass test dose design (consumption g.a.i./ha)
Table 5 reagent agent prevents and kill off acalypha copperleaf, kitchen garden test dose design (consumption g.a.i./ha)
Application method: tested in lady's-grass, barnyard grass, acalypha copperleaf 2 leaf 1 heart stage, the cauline leaf even spraying process of kitchen garden 4 leaf phase.Accurately calculate by accurate spray tower actual spray powder is long-pending and prepares required liquid, pending plastic basin annular being evenly arranged on rotating spraying platform, spraying process.Atomisation pressure 2kg/m2, Conic nozzle flow 100ml/min, repeat for 4 times.
Weedy rices method, time and number of times: the damage symptoms (as growth inhibition, chlorosis, deformity etc.) recording weeds after dispenser in detail, weighs each process weeds acrial part fresh weight after 20 days, calculate fresh weight preventive effect.
Drug effect computational methods: the evaluation of result of the test Gowing method use with after synergy type.Gowing law theory preventive effect calculating formula is:
In formula, X, Y are respectively the anti-valid value of actual measurement (%) of two single doses, E is the anti-valid value of actual measurement (%) that different ratio is used with, E0 is theoretical anti-valid value (%), when E-E0 is summation action between-10 ~ 10 time, is synergistic effect as E-E0>10, is antagonism as E-E0<-10.Result of the test is in table 6 and table 7:
Table 6 formamido group Sulfometuron Methyl mixed preventive effect result to lady's-grass, barnyard grass grand with methyl iodide sulphur
Table 7 formamido group Sulfometuron Methyl mixed preventive effect result to kitchen garden, acalypha copperleaf grand with methyl iodide sulphur
Be used alone formamido group Sulfometuron Methyl and methyl iodide sulphur is grand, control action is poor the phase after administration, and both mixtures, have synergistic effect.
