Two, biological activity determination and test of pesticide effectiveness example
Below in conjunction with example, content of the present invention is described further.
One), biological activity determination
The biologicall test example:
1, to the assay method of rice fulgorid (brown planthopper, Nilaparvata lugens)
The former medicine that test medicine 96% piperazine worm pyridine adopts Kesheng Group Co., Ltd., Jiangsu Prov. to produce, the 95% former medicine of chlopyrifos and, 90% Phoxim original medicine from Shandong Shengbang Lunan Pesticide Co., Ltd., the 85% former medicine of Hostathion, the 90% former medicine of Profenofos from Jiangsu Baoling Chemical Co., Ltd.After test method was mixed with mother liquor with reference to " the agricultural industry criteria NY/T1154.11-2008 of the People's Republic of China (PRC) " with former medicinal organic solvent acetone, soil temperature one 80 aqueous solution with 0.1% were by 5 series mass concentration of method configuration of geometric ratio.The examination worm is the consistent rice fulgorid nymph in 3 age of indoor feeding, physiological status.Choose the healthy and strong consistent rice seedlings in tillering stage of laboratory cultures, grubbed out, clean, be cut into the long band of 10cm root rice stem, the place dries in the air anhydrous to the surface in the cool place, the rice stem is flooded 30s in the medicament that configures, taking-up is dried, and encases the root moisturizing with absorbent cotton, the outsourcing preservative film, be placed in test tube, every test tube 3 strains.4 repetitions of every processing, and establish the processing that does not contain medicament and do blank.To try worm with pest sucking device and move in test tube, 15, every test tube, the mouth of pipe covers with gauze.Examination worm after processing is placed in temperature (25 ± 1) ℃, relative moisture 60%～80%, and periodicity of illumination is raise under L: D=(16: 8) h condition and observe.Carry out statistical analysis with the DPS data processing software, calculate the LC of each medicament
50, estimate reagent agent to the activity of examination worm with this.
2, to rice-stem borer Toxicity Determination method
Test method with pymetrozine and the former medicinal acetone solution of cartap and dilution, according to preliminary experiment, arranges 5 series mass concentration according to the method for geometric ratio with reference to " the agricultural industry criteria NY/T1154. of the People's Republic of China (PRC) foretell 2006 ".Choose the culture dish that is placed in of neat and consistent in the length of time with writing brush, will try worm and carry out the drop processing by head with the micro intravenous drip device, droplet positions is on the polypide pronotary, and every drop medicament 1.0uL moves to the examination worm after the drop processing under normal condition and raises.Every processing 4 times repeats, and often repeats to be no less than 10 examination worms.And establish the correspondence that does not contain medicament organic solvent processing in contrast, process rear 24 hours observation survey insect death condition.Carry out statistical analysis with the DPS statistical analysis software, calculate the LC of each medicament
50, estimate according to this reagent agent to the activity of examination worm.
3, co-toxicity evaluation method
Calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun.
The co-toxicity coefficient of mixture (CTC value) calculates by following formula:
AT1＝S/M×100
In formula:
AT1----mixture actual measurement toxicity index;
The LC of s----standard insecticide
50, unit is every liter (mg/1) of milligram;
The LC of M----mixture
50, unit is every liter (mg/1) of milligram;
TTI＝TIA×PA+TIB×PB
In formula:
The theoretical toxicity index of TTI----mixture;
TIA----A medicament toxicity index;
The percentage composition of PA----A medicament in mixture, unit are percentage;
TIB----B medicament toxicity index;
The percentage composition of PB----B medicament in mixture, unit are percentage.
CTC＝AT1/TTIx100
In formula:
The CTC----co-toxicity coefficient;
AT1----mixture actual measurement toxicity index;
The theoretical toxicity index of TTI----mixture.
The co-toxicity coefficient of built agent (CTC) 〉=120 shows as synergistic effect; CTC≤80 show as antagonism; 80＜CTC＜120 show as summation action.

2To water 45kg, after checking the insect population radix, aim at manually evenly complete stool spraying of rice seedling by above-mentioned design dosage, during dispenser and after medicine in the week field keep water layer.1 day, 7 days and inspection in 15 days borer population (seeing Table 3) alive after medicine.
From the results shown in Table 3: the composite rear various formulation synergistic effects of the pyridine of piperazine worm and organophosphorus insecticide are obvious; After dispenser 1 day, 7 days and 15 days, each compound drug also significantly better than single dose, illustrated that the pyridine of piperazine worm and organophosphorus insecticide speed religion property and the lasting effect after composite all is better than piperazine worm pyridine single dose, has the notable synergistic effect to the control efficiency of brown planthopper.
Annotate: A, 20% piperazine worm pyridine suspending agent; B, 40% chlorpyrifos ec; C, 40% phoxim emulsifiable concentrate; D, 40% Profenofos missible oil; E, 20% triazophos emulsifiable solution; Gai/ha is the per hectare effective ingredient consumption.

2) control of rice leaf roller is tested
Tested in July, 2009 and carry out at suburb, Nanjing paddy field, test adopts knapsack sprayer to carry out the method for full field spraying; Choose Development of Rice consistent, the field that rice leaf roller is evenly distributed, the rice leaf roller in this period 80% was in for 3 ages, and the insect population radix is counted, 1 day, 7 days and inspection in 15 days borer population (table 4) alive after medicine.
From the results shown in Table 4: the composite rear various formulation synergistic effects of the pyridine of piperazine worm and organophosphorus insecticide are obvious; After dispenser 1 day, 7 days and 15 days, each compound drug also significantly better than single dose, illustrated that the pyridine of piperazine worm and organophosphorus insecticide can improve the rice leaf roller control efficiency after composite, have the notable synergistic effect to the control efficiency of rice leaf roller.
Annotate: A, 20% piperazine worm pyridine suspending agent; B, 40% chlorpyrifos ec; C, 40% phoxim emulsifiable concentrate; D, 40% Profenofos missible oil; E, 20% triazophos emulsifiable solution; Gai/ha is the per hectare effective ingredient consumption.
