Description
【Technical field】
The invention belongs to technical field of pesticide.It is more particularly it relates to a kind of containing sulphur insect amide and clothianidin
Pesticidal combination, further relate to the purposes of the Pesticidal combination.
【Background technology】
Planthopper is the main insect of rice, and its harm occurred has hiding, fulminant and destructive feature.
Planthopper is a kind of migratory pest, usually causes the significant loss of crop, seriously endangers the Rice Production in China.With chemistry
The continuous administration of medicament, resistance problem become increasingly conspicuous, and in agricultural production real process, pest resistance to insecticide problem is to influence evil
An important factor for worm prevention effect.Different active ingredients are carried out into compounding can expand preventing and treating spectrum and raising preventive effect, be that insect resists
Property administer effective measures.
Thiobenzamide insecticides can be combined with ryanodine receptor, cause Ca2+The out of control and loss of release, makes muscle
The contractile function paralysis of cell, it is the compound of brand-new mechanism of action.Insect after chemicals treatment shows as feed and stopped rapidly
Only, weak, gastric disorder causing nausea and Muscle paralysis, until dead.This insecticides insecticidal spectrum is wide, the longevity of residure is long, toxicity is low, to environment friend
It is good, with existing each insecticides no interactions resistance.Each Lepidopterous, homoptera pest and some elytrums can effectively be prevented and treated
Mesh larva, adult, it can be also used for preventing and treating the insects such as ant, termite.The A of CN 103109816 disclose a kind of new thio phenyl
Carbox amide, in its general structure I, R1Selected from Cl or Br；R2Selected from methyl, isopropyl or pi-allyl；R3Selected from H or
Cl.They have excellent insecticidal activity, the preventing and treating available for agricultural or forestry pest.CN 103130770A disclose one kind
3,5- dihalo thiobenzamide insecticides, in its general structure I, R1Selected from Cl or Br；R2Selected from methyl, isopropyl or
Pi-allyl；R3Selected from H or Cl.They can be used for the preventing and treating of agricultural or forestry pest.
Clothianidin is a kind of insecticide in anabasine, is a kind of highly effective and safe, the novel pesticide of high selectivity, its
Effect is similar with nAChR, with tag, stomach toxicity and systemic activity.It is mainly used in rice, vegetables, fruit tree and
Prevent eliminating aphis on other crops, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, Diptera and some Lepidoptera class pests kill
Worm agent.
But there are some technological deficiencies in these prior arts, be not met by current agricultural production needs, therefore also need
The Pesticidal combination of new efficient preventing and treating rice pest is developed, this is of crucial importance for promoting agriculture large-scale development to have
Meaning.

2nd, the measure of bioactivity
In order to further appreciate that the virulence of sulphur insect amide and clothianidin composition, a large amount of formulation screening tests have been carried out.
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：
Contents (%) of mixed toxicity index (the TTI)=A of the theory toxicity index × A in mixed
Contents (%) of+B toxicity index × B in mixed
When co-toxicity coefficient is more than 120, show that this mixture has synergistic effect；And co-toxicity coefficient be less than 80 when, show
This mixture has antagonism；And co-toxicity coefficient be more than 80 less than 120 when, show that 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

The regulation of preventing and treating water rice hopper " carries 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
Energy effectively preventing rice after HY366 compounds with clothianidin is can be seen that from above-mentioned field control effectiveness test result to fly
Lice, 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 clothianidin preparations, 7d reaches 89.3%- to water rice hopper preventive effect after administration
92.7%, after administration 14d 90.4%-94.7% is reached to preventive effect, far above HY366 and the preventive effect of clothianidin single dose.
(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.
