2nd, the measure of bioactivity
In order to further appreciate that the virulence of sulphur insect amide and flonicamid cyanide composition, a large amount of recipe determination examinations have been carried out
Test.
Pesticidal combination biological activity determination of the present invention is as follows：
Using infusion process processing tea lesser leafhopper (Empoasca pirisuga Matumura), according to pesticide room
Interior bioassay test criterion (agricultural industry criteria NY/T1154.7-2006) and initiative pesticide bioactivity evaluation SOP (desinsections
Agent is rolled up), measure single dose LC50With mixture LC50。
Target selects Brown Planthopper (Nilaparvata legen), indoor to raise worm kind (27 with rice seedling throughout the year
DEG C, 14h illumination/d).Selection indoor feeding to the consistent larva of 3 age mid-terms is for experiment.Using spray-on process.Test rice children
Seedling is cultivated to the rice seedling of the heart of 2 leaf 1 (being about 3~4cm) from water culture, is cleaned with clear water standby.By 4~6 rice seedlings
It is fixed on crystobalite sand in Φ 7cm culture dish, connects the Brown Planthopper 3 age mid-term larva 30 of CO2 anesthesia, be placed in
Quantitative (2.5mL) spraying treatment (pressure 5Ib/iW2, settling amount 4.35mg/cm2), experiment are set not under Potter spray towers
Corresponding organic solvent processing containing medicament is control, and often processing is repeated 4 times, and is covered after spraying with transparent plastic cup, is put in temperature
Inspection result after 27 DEG C of observation indoor illuminations 14h, 3d, polypide is touched with writing brush, reactionless to be considered as dead worm.Count each processing
Borer population living and total borer population, calculate the death rate and corrected mortality (Abbott ' s formula) of each processing；With " DPS data processings system
System " V14.50 professional versions carry out data analysis statistical, obtain regression straight line, LC50Value.Calculated with the abundant methods of Sun Yun (Sun etc., 1960)
Toxicity index, co-toxicity coefficient is calculated by following formula：
Content (the %)+B of mixed toxicity index (the TTI)=A of theory toxicity index × A in mixed toxicity index
Contents (%) of × B in mixed
When co-toxicity coefficient is more than 120, show that this mixture has synergistic effect；And poison is altogether
When number is less than 80, show that this mixture has antagonism；And co-toxicity coefficient be more than 80 less than 120 when, show
This mixture has summation action.
HY366 the results are shown in Table 1 with MTI-446 different ratio mixture to the Toxicity Determination of planthopper
Table 1：HY366 compounds the Toxicity Determination result to planthopper with sulfoxaflor
Can be seen that sulphur insect amide with sulfoxaflor mixture from above-mentioned Toxicity Determination result is 1 in mass ratio:
100~100:Its co-toxicity coefficient is all higher than 120 in the range of 1, shows that sulphur insect amide has with sulfoxaflor mixture to planthopper
There is significant synergistic effect.
3rd, the experiment of water rice hopper Field information is prevented and treated
According to medicine inspecting institute of the Ministry of Agriculture, " GB-T 17980.4-2000 pesticide field efficacy medicine tests criterions (one)-insecticide is prevented
Harness the river planthopper " regulation carry out experiment.
Test site：The small towns Ming Lun villages of Ningbo City, Zhejiang Province Yinzhou District five.
Test period：6 days~the September of September in 2014 20 days.
Test method：Rise's boot period dispenser is once.Rice hoppers are based on low instar larvae.
Formulation rate is 750kg/hm2, plant blade face even spraying.Plot area 25m2, 4 repetitions, random district's groups arrangement.
Per the 10 points of samplings of the parallel jump method in experimental plot, every is investigated 2 clumps, investigates 20 clumps altogether, investigates every 2 clumps of work borer populations taken.
According to investigation result, Revision insect recluced rate and preventive effect are calculated according to formula below (1) and (2).
Test data carries out statistical analysis using Deng Kenshi duncan's new multiple range methods (DMRT).
Table 2 prevents and treats water rice hopper field control effectiveness test result
HY366 and energy effectively preventing water after sulfoxaflor compounding are can be seen that from above-mentioned field control effectiveness test result
Planthopper, preventive effect are better than comparison medicament.To trial crops safety in scope of medication.
Summary, indoor biometricses and field control effectiveness test result show that Pesticidal combination of the present invention has and following had
Beneficial effect：
(1) compared with single dose, the Pesticidal combination has significant synergistic effect to preventing and treating planthopper, extends the lasting period,
Improve effect；Using 10%-70%HY366 sulfoxaflor preparations, 7d reaches to water rice hopper preventive effect after administration
90.7%-93.9%, after administration 14d 90.9%-95.3% is reached to preventive effect, far above HY366 and sulfoxaflor single dose
Preventive effect.
(2) times for spraying is reduced, lowers drug cost, reduces environmental pollution and residues of pesticides；
(3) composition is made up of the active ingredient of different mechanism of action, action site increase, is advantageous to overcome and is delayed to do harm to
The drug-fast generation of worm.The present composition is equal to trial crops all normal without obvious harmful effect, leaf color, growing way etc., safety
Property is good, meets the security requirement of pesticidal preparations.
Pesticidal combination of the present invention has good preventive effect to water rice hopper.
