Experiment soil is quantitatively filled at the 4/5 of basin alms bowl.Choose green bristlegrass that is full, uniform, having no mechanical damage, dent Amaranth, barnyard grass, concave head amaranth, chickweed, eleusine indica, volume stem smartweed, pivots store or moleplant seed seed, and after being impregnated for 24 hours with clear water, it is uniformly spread It is sowed at the round plastic nutritive cube surface equipped with soil, a diameter of 30cm, broadcasts 30~40 per basin, earthing 1.0cm.It is perennial miscellaneous Careless chufa, sowthistle, alternanthera philoxeroides 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 metribuzin) be selected from active constituent B (clomazones, Oxyfluorfen, lactofen, fluoroglycofen-ethyl, imazethapyr, bentazone, trefanocide, sulfentrazone, AC 263222, Acetochlor, pendimethalin, metazachlor He Evil humulones) medicament mixture after, practical preventive effect is all higher than theoretical anti- It imitates (it is expected that preventive effect), illustrates that active components A has synergistic effect with the medicament mixture in active constituent B.
1 diclosulam of table, metribuzin Yu clomazones mixture are to the synergy effect of green bristlegrass
The synergy effect of 2 diclosulam of table, metribuzin and Oxyfluorfen mixture to chufa
The synergy effect of 3 diclosulam of table, metribuzin and lactofen mixture to sowthistle
The synergy effect of 4 diclosulam of table, metribuzin and fluoroglycofen-ethyl mixture to purslane
The synergy effect of 5 diclosulam of table, metribuzin and imazethapyr mixture to barnyard grass
The synergy effect of 6 diclosulam of table, metribuzin and bentazone mixture to concave head amaranth
The synergy effect of 7 diclosulam of table, metribuzin and trefanocide mixture to chickweed
The synergy effect of 8 diclosulam of table, metribuzin and sulfentrazone mixture to eleusine indica
The synergy effect of 9 diclosulam of table, metribuzin and AC 263222 mixture to alternanthera philoxeroides
The synergy effect of 10 diclosulam of table, metribuzin and Acetochlor mixture to volume stem smartweed
The synergy effect of 11 diclosulam of table, metribuzin and pendimethalin mixture to the rhizome of nutgrass flatsedge
The synergy effect that 12 diclosulam of table, metribuzin and metazachlor mixture Dui pivots store
13 diclosulam of table, metribuzin Yu Evil humulones mixtures are to the synergy effect of moleplant seed
