The security requirement of pesticidal preparations.It is limited by length, specifiable embodiment is as follows, but is not restricted to this.
Specific implementation mode
(1) Toxicity Determination is tested
It is small to Meloidogyne incognita and wild cabbage by Toxicity Determination research compound 1 and betacyfluthrin compounding
The control effect of diamond-back moth.
1, for the Toxicity Determination of Meloidogyne incognita.
Experiment uses Meloidogyne incognita (Meloidogyne spp.) for test object, high with compound 1 and efficient fluorine
It imitates cyfloxylate compounding and carries out Toxicity Determination.Test method：With reference to《NY/T1833.1-2009 pesticide indoor biologicals are surveyed
Determine test rule nematicide part 1 and inhibits plant pathogeny line insect experiment 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.According to drug concentration logarithm and the probability of the corrected mortality of corresponding target
Value does regression analysis, calculates the LC of each medicament50, evaluate after two kinds of composite reagents to the activity of nematode.Simultaneously according to Sun Yunpei's Method
Co-toxicity coefficient method (CTC) evaluate the synergistic effect of pharmacy mix, i.e. CTC≤80, composition shows as antagonism, when 80
<CTC<120, composition shows as summation action, and when CTC >=120, composition shows as synergistic effect.
1 compound 1 of table combines the The Toxicity Determination result to Meloidogyne incognita with efficient fluorine betacyfluthrin
The Toxicity Determination result shows：Compound 1 is with efficient fluorine betacyfluthrin in weight ratio 1:20-40:1 model
Enclose interior compounding has preferable virulence to Meloidogyne incognita, with weight ratio 1:5-10:The synergy that compounding obtains in 1 range is more
To be notable, especially weight ratio is 1:1-5:In 1 range, synergy is the most notable.
2, for the Toxicity Determination of wild cabbage diamondback moth.
Controlling object：Wild cabbage diamondback moth (Plutellaxylostella (L.)), test method：With reference to《The Chinese people are total
With state agricultural industry criteria NY/T1154.2-2006》.
First by single dose and each Mixed Pharmacy be arranged 5 various concentration gradients (on the basis of pilot study result, wild cabbage
The diamondback moth death rate is set in the range of 5%~90% by geometric progression).Test worm is the diamondback moth of indoor raising, is being tested
Age uniform diamondback moth is selected in room, 4~8 hours hungry, is beaten with 1 centimetre of card punch of diameter and takes leaf dish, is put into culture
Ware, and pay attention to moisturizing.With capillary dropper since low concentration, drip the 1 μ L liquids of μ L~2 per leaf dish point, waits for that solvent volatilizees
The malicious leaf dish of folder is made in the leaf dish pairing for being coated with gelatinized corn starch with another afterwards, and making, which finishes, to be put in the hole of 12 hole tissue culturing plates.
4 repetitions are often handled, often repeat the malicious leaf dish of no less than 12 folders, and set the processing conduct of the corresponding organic solvent without medicament
Control.1 test worm is inscribed in each hole of tissue culturing plate, is placed under normal condition and cultivates.After connecing worm 2~4 hours, test worm feeding is waited for
After complete drug containing leaf dish, clean feeds are added in cultivation plate hole and continue raising to investigating, eliminates and has not eaten complete leaf dish
Test worm checks dead borer population for 48 hours, calculates the death rate.It is for statistical analysis with DPS data processor softwares, calculate each medicament
LC50The co-toxicity coefficient (CTC) of value and mixture evaluates activity of the reagent agent to test worm with this.
2 compound 1 of table combines the The Toxicity Determination result to wild cabbage diamondback moth with betacyfluthrin
The Toxicity Determination result shows：Compound 1 is with betacyfluthrin in weight ratio 1:20-40:It is multiple in 1 range
Pairing wild cabbage diamondback moth has preferable virulence, with weight ratio 1:10-10:The synergy that compounding obtains in 1 range is more notable.

Table 3 prevents the field test results of Meloidogyne incognita
Table of field test results are bright, example of formulations 1 (17% compound, 1 betacyfluthrin granule) and preparation
Embodiment 2 (15% compound, 1 betacyfluthrin granule) has a good control effect to Meloidogyne incognita, after medicine
15 days preventive effects are higher than 70%, hence it is evident that are better than 10% compound, 1 granule and 2.5% betacyfluthrin missible oil.Experiment institute
There is processing without obvious harmful effects to the growth of tomato, tomato fruit and yield are normal.
2, to the field efficiency test of wild cabbage diamondback moth.
Inventor has carried out prevention wild cabbage diamondback moth field control effectiveness test in 2017 in Shouguang City of Shandong Province, demonstrates this
Medicament is to the control effect of wild cabbage diamondback moth and to (13% compound, the 1 betacyfluthrin water-dispersible grain of sweet formulation examples 5
Agent), the safety of example of formulations 6 (12% compound, 1 betacyfluthrin aqueous emulsion) indigo plant.
Trial crops are wild cabbage, and controlling object is diamondback moth.Experimental field soil be sandy loam, middle fertility, each cell
Cultivation condition, water and fertilizer management uniformity.Test medicine and dosage refer to table 4.It it is 40L/ mus with liquid volume, using hand spray
Device uniformly sprays, it is desirable that each cell cabbage leaves uniformly medicine.Blank control separately is set, often handles 4 repetitions, per plot area 28
㎡, totally 32 cells, random district's groups arrange.Insect population is investigated before dispenser, investigates survival insect population number, root respectively within 7,15 days after medicine
Control effect is calculated according to following formula.
Insect population × 100 before Revision insect recluced rate (%)=(borer population living after insect population-medicine before medicine)/medicine
Control effect (%)=(treatment region Revision insect recluced rate-clear area Revision insect recluced rate)/(clear areas 100- insect population declines
Rate) × 100
Table 4 prevents wild cabbage diamondback moth field test results
Table of field test results are bright, formulation examples 5 (13% compound, 1 betacyfluthrin water dispersible granules), system
Agent embodiment 6 (12% compound, 1 betacyfluthrin aqueous emulsion) has a good control effect to wild cabbage diamondback moth, after medicine
15 days preventive effects are above 90%, hence it is evident that are better than 10% compound, 1 granule and 2.5% betacyfluthrin missible oil.To sweet
Blue security survey is observed daily after spray, and wild cabbage occurs without poisoning phenomenon for each test process.Compared with check plot, place
It manages region wild cabbage yield and is higher than control zone.
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.
