Experiment soil is quantitatively filled at the 4/5 of basin alms bowl.Choose moleplant seed that is full, uniform, having no mechanical damage, sweet wine intestines, Setaria glauca, acalypha copperleaf, Itanlian rye, artemisiifolia, black nightshade, cyperus iria, ox chickweed or speedwell seed, are impregnated with clear water After for 24 hours, by its uniform broadcasting in the round plastic nutritive cube surface equipped with soil, a diameter of 30cm, 30~40 is broadcast per basin, is covered Native 1.0cm.Perennial weeds meadow pine, field thistle or the rhizome of nutgrass flatsedge take underground rhizome (long-rhizomes such as 3cm) from field, and 10 are planted per basin Section.The moisturizing in a manner of the bottom infiltrating irrigation of basin alms bowl, makes soil be moistened completely to saturation state.Sowing for 24 hours afterwards by prepared liquid into Row soil is sprayed.Then move into culture in controllable heliogreenhouse.4 repetitions of often processing setting, repeat 5 basins, with not drug containing every time Agent processing is blank control.
21d after chemicals treatment, using absolute value (number is surveyed) investigation method investigation records activity of weeding, with weighing each processing weeds Upper part fresh weight calculates practical preventive effect, and is evaluated and acted synergistically according to Colby methods.Referring to COLBY, S.R.：" calculate herbicide The collaboration of combination and Antagonistic reaction ", Weeds 15, p.20~22,1967：
According to survey data, the practical preventive effect of each processing is calculated by formula (1), unit is percentage (%), result of calculation Retain 2 significant digits.
In formula：
The practical preventive effects of E-；
C-control weeds aerial part fresh weight；
T-processing weeds aerial part fresh weight.
Colby methods：Theoretical preventive effect (it is expected that preventive effect) E of Mixed Pharmacy0(2) formula calculates：
In formula：
Practical preventive effect when 1 dosage of X-herbicide is P；
Practical preventive effect when 2 dosage of Y-herbicide is Q；
Practical preventive effect when 3 dosage of Z-herbicide is R；
E0The theoretical preventive effect that 1 dosage of-herbicide is 2 dosage of P+ herbicides when be 3 dosage of Q+ herbicides being R, i.e. mixture are removed The expection preventive effect of careless agent；
E-herbicide 1,2 and 3 presses practical preventive effect when different ratio mixture；
As E ＞ E0When, i.e., it, should if the practical preventive effect of Mixed Pharmacy is more than the theoretical preventive effect (it is expected that preventive effect) calculated Combination just has super superposition, that is, acts synergistically.
2, test result
Test result refers to table 1~13, it is seen then that active components A (diclosulam and flufenacet) with selected from activity at Divide B (AC 263222, sulfentrazone, sethoxydim, fomesafen, clomazones, pendimethalin, imazethapyr, thiophene sulphur Grand, trefanocide, metribuzin, bentazone and fluoroglycofen-ethyl) medicament mixture after, practical preventive effect be all higher than theoretical preventive effect (it is expected that Preventive effect), illustrate that active components A has synergistic effect with the medicament mixture in active constituent B.
The synergy effect of 1 diclosulam of table, flufenacet and AC 263222 mixture to moleplant seed
The synergy effect of 2 diclosulam of table, flufenacet and sulfentrazone mixture to sweet wine intestines
The synergy effect of 3 diclosulam of table, flufenacet and sethoxydim mixture to setaria glauca
The synergy effect of 4 diclosulam of table, flufenacet and fomesafen mixture to acalypha copperleaf
5 diclosulam of table, flufenacet Yu clomazones mixture are to the synergy effect of meadow pine
The synergy effect of 6 diclosulam of table, flufenacet and pendimethalin mixture to Itanlian rye
The synergy effect of 7 diclosulam of table, flufenacet and imazethapyr mixture to artemisiifolia
