Application effect example：
1st, test method
Reference《The 4th part of NY/T 1155.4-2006 farm-chemical indoor determination test rules herbicide：Determination of activity tries Test cauline leaf spray-on process》Carry out.
Experiment, which is located under greenhouse experiment, to be carried out.Choose several small in grassy weed, broad leaved weed and sedge weed Wheatland representativeness weeds sonchus oleraceus, volume stem smartweed, amur foxtail, the rhizome of nutgrass flatsedge, conical silene herb, clearvers, wild oat, shepherd's purse, chickweed, successively Wheat, lolium temulentum, field bindweed and Itanlian rye are for examination weeds.The rhizome of nutgrass flatsedge and field bindweed are perennial weeds, take ground from field Lower Propagation of Rhizomes；Remaining several weeds is annual grassy weeds, from field collection weed seed breeding.
It will be quantitatively filled at the 4/5 of basin alms bowl for examination soil, using basin alms bowl bottom infiltrating irrigation mode, soil is moistened completely to full And state.Choose sonchus oleraceus that is full, uniform, having no mechanical damage, volume stem smartweed, amur foxtail, conical silene herb, clearvers, wild oat, shepherd's purse Dish, chickweed, Triticum tauschii, lolium temulentum or Itanlian rye seed, by its uniform broadcasting in the round plastic nutritive cube of a diameter of 30cm Surface, broadcasts 30~40, earthing 1.0cm per basin.The perennial weeds rhizome of nutgrass flatsedge or field bindweed take underground rhizome (3cm from field Deng long-rhizome), 10 sections are planted per basin.The after planting moisturizing in a manner of the bottom infiltrating irrigation of basin alms bowl, makes soil moisten completely to saturation state. When length is to 2~3 leaf phase, per 30 plants of basin final singling.When weeds were grown to 3~4 leaf phase, liquid is sprayed with hand micro-sprayer, Spouting liquid keeps ground moistening often to handle 60mL after medicine.Often processing sets 4 repetitions, if blank is made in the processing without medicament Control.After processing after liquid natural air drying, cellar culture observation in greenhouse is moved into.
21d after chemicals treatment, investigation method investigation records activity of weeding (is counted and surveys) using absolute value, with weighing each processing weeds Upper part fresh weight, calculates actual 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 actual preventive effect of each processing is calculated by formula (1), unit is percentage (%), result of calculation Retain 2 significant digits.
In formula：
E-actual preventive effect；
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：
Actual preventive effect when 1 dosage of X-herbicide is P；
Actual preventive effect when 2 dosage of Y-herbicide is Q；
Actual preventive effect when 3 dosage of Z-herbicide is R；
E01 dosage of-herbicide is that 2 dosage of P+ herbicides is theoretical preventive effect when 3 dosage of Q+ herbicides is R, i.e. mixture is removed The expection preventive effect of careless agent；
E-herbicide 1,2 and 3 presses actual preventive effect during different ratio mixture；
As E ＞ E0When, i.e., should if the actual preventive effect of Mixed Pharmacy exceedes the theoretical preventive effect (it is expected that preventive effect) calculated Combination just has super superposition, that is, acts synergistically.
