1）Toxicity determination test
Test objective：Ethoxysulfuron is compounded to lady's-grass, the herbicidal effect of difformed galingale herb with flufenacet under the conditions of greenhouse pot culture； Ethoxysulfuron is compounded to amur foxtail, the herbicidal effect of arrowhead with pyroxsulam；Ethoxysulfuron and clodinafop-propargyl are compounded to wild oat, different The herbicidal effect of type nutgrass flatsedge；Ethoxysulfuron is compounded to bromegrass, the herbicidal effect of difformed galingale herb with flucarbazone；And have rated respectively Its synergy.
For studying thing：Wheat.
Prevent and kill off object：Prevent and kill off object：Grassy weed：Lady's-grass, amur foxtail, wild oat, bromegrass；Broad leaved weed：Special-shaped Sha Grass, arrowhead.
Material to be tested：97% ethoxysulfuron active compound, 95% flufenacet active compound, 96.5% pyroxsulam active compound, 95% clodinafop-propargyl Active compound, 96% flucarbazone active compound.
Test method：
Ethoxysulfuron is compounded with flufenacet, and object is surveyed as raw using lady's-grass, difformed galingale herb；Ethoxysulfuron is answered with pyroxsulam Match somebody with somebody, object is surveyed as raw using amur foxtail, arrowhead；Ethoxysulfuron is compounded with clodinafop-propargyl, surveys right as raw using wild oat, difformed galingale herb As；Ethoxysulfuron is compounded with flucarbazone, and object is surveyed as raw using bromegrass, difformed galingale herb.
From herbicide, pH6.8 soil was not applied, after soil is air-dried into sieving, load 6cm high, the plastics of diameter 9cm In alms bowl, 20 seeds are sowed per basin, culture greenhouse in is placed on after lid 0.5-1cm thick fine earth, treated that weeds are long and use to the 2-4 leaf phases Potted plant cauline leaf process method（NY/T 1155.4-2006）, per alms bowl spraying liquid 1mL, often treatment is repeated 4 times, and sets the place without medicament It is control to manage.Material is tried after treatment and is placed in culture in greenhouse, the growing state of routine observation target weeds is estimated target and received after 20d Evil symptom and growth inhibition situation, and claim aerial part fresh weight or strain fresh weight, medicament is evaluated to target with target fresh weight inhibition The toxicity action of weeds.
Specific method is with reference to the part of NY/T1155.4-2006 farm-chemical indoor determination test rules herbicide the 4th：Activity Determination test cauline leaf spray-on process is tested, and often processes 4 repetitions, often repeatedly 20 plants, if being blank without chemicals treatment.
Binary built synergy evaluation method is removed with reference to NY/T1155.7-2006 farm-chemical indoor determination test rules Colby methods in the synergy measure of the part mixture of careless agent the 7th.
If E be ethoxysulfuron and flufenacet or pyroxsulam or clodinafop-propargyl or flucarbazone it is mixed after the weeds of actual measurement weigh Measure to compare the percentage of weeds weight.
The theoretical preventive effect of mixture is calculated according to below equation：
E0=X×Y/100
In formula, X is that ethoxysulfuron weeds weight under certain dosage is the percentage for compareing weeds weight；Y is flufenacet or pyridine Sulphur grass amine or clodinafop-propargyl or flucarbazone the weeds weight under certain dosage is the percentage for compareing weeds weight.
E-E0＞ 10% is antagonism；E-E0＜ -10% is synergistic effect；E-E0Value is between ± 10% for addition is made With.
