Experiment uses Meloidogyne incognita (Meloidogyne spp.) for test object, with compound 1 and efficient fluorine ring
Oxygen worm pyridine compounding carries out Toxicity Determination.Test method：With reference to《NY/T1833.1-2009 farm-chemical indoor determinations are tested
Criterion nematicide part 1 inhibits plant pathogeny line insect to test dip method》.
According to survey data, the death rate and corrected mortality of each processing are calculated, unit is percentage (%), according to formula
Calculate the death rate and corrected mortality.LC is obtained using DPS data processing softwares50Value, and thus calculate mixture
Co-toxicity coefficient (CTC).The synergistic effect of pharmacy mix, i.e. CTC are evaluated according to the co-toxicity coefficient method (CTC) of Sun Yunpei's Method simultaneously
≤ 80, composition shows as antagonism, when 80<CTC<120, composition shows as summation action, when CTC >=120, composition
Show as synergistic effect.
1 compound 1 of table combines the The Toxicity Determination result to Meloidogyne incognita with cycloxaprid

Square root-knot nematode has preferable virulence, with weight ratio 1:15-10:The synergy that compounding obtains in 1 range is more notable, especially
It is weight ratio 1:10-2.5:In 1 range, synergy is the most notable.
2, for the Toxicity Determination of black peach aphid.
Toxicity Determination is carried out using dip method.Compound 1 and cycloxaprid active compound are configured to 5 series concentrations
Liquid, it is spare.Black peach aphid (Myzus persicae) nymph for selecting indoor culture, age consistent, immerses liquid by target insect
After 10s, extra liquid is drawn with filter paper, test worm is transferred under normal condition and is raised, often processing is repeated 4 times, and often repeats leaching worm
10, be control with clear water processing.Check that number of dead and live insects, experiment of the control group death rate less than 20% are effectively examination afterwards for 24 hours
It tests.
According to investigation result, the death rate of each processing is calculated.LC is obtained using DPS data processing softwares50Value, and thus count
Calculate the co-toxicity coefficient (CTC) of mixture.When co-toxicity coefficient is more than 120, indicate to show as synergistic effect between two component of mixture；Poison altogether
Coefficient indicates to show as addition between two component of mixture between 80-120；Co-toxicity coefficient is less than 80, indicates mixture two
Antagonism is shown as between component.
2 compound 1 of table combines the The Toxicity Determination result to black peach aphid with cycloxaprid
The Toxicity Determination result shows：Compound 1 is with cycloxaprid in weight ratio 1:40-30:Compounding is to peach in 1 range
Aphid has preferable virulence, with weight ratio 1:20-10:The synergy that compounding obtains in 1 range is more notable, especially weight ratio
1:10-10:In 1 range, synergy is the most notable.

(3) field control effectiveness test
1, to Meloidogyne incognita field control effectiveness test
Inventor has carried out (20% compound, 1 cycloxaprid of example of formulations 1 in 2017 in Shouguang City of Shandong Province
Granula), example of formulations 2 (43% compound, 1 cycloxaprid wettable powder) prevention Meloidogyne incognita field efficacy examination
It tests, demonstrates control effect of the medicament to Meloidogyne incognita and the safety to tomato.
Trial crops are tomato, and controlling object is root-knot nematode, experimental field flat, and nematode worm amount is big.Experiment using mispickel/
Native broadcast application, each processing are repeated 4 times, cell random alignment, per cell 15m2, totally 32 cells.
Investigation method：Aggrieved suspicious diseased plant is found, is sampled for 5 points using diagonal line, every 2 plants of investigation, calculating incidence,
Disease index and control effect.
Diseased plant stage division：
0 grade：Root system is without insect gall；
1 grade：Root system has a small amount of small insect gall；
3 grades：2/3rds root systems are covered with small insect gall；
5 grades：Root system is covered with small insect gall and has secondary insect gall；
7 grades：Root system forms fibrous root group.
Table 3 prevents the field test results of Meloidogyne incognita
Table of field test results are bright, example of formulations 1 (20% compound, 1 cycloxaprid granule), example of formulations 2
(43% compound, 1 cycloxaprid wettable powder) has a good control effect to Meloidogyne incognita, 15 days anti-after medicine
Effect is higher than 70%, hence it is evident that is better than 10% compound, 1 granule and 25% cycloxaprid wettable powder.Test it is all processing to kind
The growth of eggplant is without obvious harmful effects, and tomato fruit and yield are normal.
2, to aphid field efficiency test.
Inventor has carried out (28% compound, the 1 cycloxaprid suspension of formulation examples 3 in 2017 in Shouguang City of Shandong Province
Agent), the anti-field control effectiveness test that eliminates aphis of example of formulations 6 (32% compound, 1 cycloxaprid emulsion in water), demonstrate the medicament
Control effect to aphid and the safety to vegetables.
Trial crops are wild cabbage, and controlling object is black peach aphid.Experimental field soil is sandy loam, middle fertility, the cultivation of each cell
Training condition, water and fertilizer management uniformity, former years aphid occur heavier.Test medicine and dosage refer to table 4.It is 40L/ with liquid volume
Mu, uniformly sprayed using hand sprayer, it is desirable that each cell cabbage leaves uniformly medicine.Blank control separately is set, often handles 4 weights
Multiple, per 28 ㎡ of plot area, totally 32 cells, random district's groups arrange.
Investigation method：2 are investigated per cell, take the two aphid number average value living to be counted as every plant of aphid and quantity occurs.
The anti-field test results that eliminate aphis of table 4
Table of field test results are bright, formulation examples 3 (28% compound, 1 cycloxaprid suspending agent), example of formulations 6
(32% compound, 1 cycloxaprid emulsion in water) has a good control effect to aphid, and 15 days preventive effects are higher than 85% after medicine, bright
It is aobvious to be better than 10% compound, 1 granule and 25% cycloxaprid wettable powder.Security survey to wild cabbage, after spray daily
Wild cabbage occurs without poisoning phenomenon for observation, each test process, and wild cabbage yield is not significantly affected.
In conclusion the composition of the present invention is to use two kinds of active components compound scheme, insecticidal activity is not each group
Active simple superposition is divided other than there is significant insecticidal effect, more to there is significant synergy compared with existing single formulation
Effect, safety is good to making, and meets the security requirement of pesticidal preparations.
