Description
【Technical field】
The invention belongs to technical field of pesticide.More particularly it relates to which a kind of contain sulphur insect amide and Tolfenpyrad
Pesticidal combination, further relate to the purposes of the Pesticidal combination.
【Background technology】
Tea lesser leafhopper (Empoasca pirisuga Matumura), Homoptera, Cicadellidae Cicadellidae is commonly called as
Leafhopper, leaf springtail etc., each production tea in the whole nation is saved, there is generation in autonomous region, is one of main tea insects.8- occurred in 1 year for this worm
Or so 12 generations, and the alternation of generations.Serious Summer-autumn tea of causing harm, aggrieved tea tree bud-leaf is rolled up, hardened, blade tip and leaf margin are reddish brown dried-up,
The bud tip is slow-growing, very big to tea yield and qualitative effects.And with the continuous administration of chemical agent, resistance problems day
Benefit is prominent, and in agricultural production real process, pest resistance to insecticide problem is to influence the key factor of pest controling effect.Will not
Preventing and treating spectrum and raising preventive effect can be expanded by carrying out compounding with active ingredient, be the effective measures of pest resistance treatment.
Sulphur insect amide (HY366) can be combined with ryanodine receptor, cause Ca2+The out of control and loss of release, makes muscle cell
Contractile function paralysis, be the compound of brand-new mechanism of action.Insect after chemicals treatment shows as feeding rapid stopping, weary
Power, gastric disorder causing nausea and Muscle paralysis, until dead.This insecticides insecticidal spectrum is wide, longevity of residure length, toxicity are low, environmentally friendly, and existing
Each insecticides no interactions resistance having.Each Species of Lepidopterous Insect Pests and some coleoptera larvaes, adult can be effectively prevented and treated, also
It can be used for the insects such as preventing and treating ant, termite.
The main mechanism of Tolfenpyrad (Tolfenpyrad) is the oxidative phosphorylation for preventing insect, is also had
Ovicidal, suppression food, suppression spawning and bactericidal action.The medicine insecticidal spectrum is very wide, to Homoptera tea lesser leafhopper, lepidopterous larvae pickles
Moth, Thysanoptera thrips etc. have special efficacy, and have higher prevention effect to mite class.
But, there are some technological deficiencies in these prior arts, be not met by current agricultural production needs, therefore also need
New efficient preventing and treating paddy rice, the Pesticidal combination of vegetable insect disease are developed, this is for promoting agriculture large-scale development to have pole
Its important meaning.

2nd, the measure of bioactivity
In order to further appreciate that the virulence of sulphur insect amide and Tolfenpyrad composition, a large amount of formulation screening tests have been carried out.
Pesticidal combination biological activity determination of the present invention is as follows：
Handled using infusion process in taken outdoors age identical tea lesser leafhopper (Empoascapirisuga
Matumura), according to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.7-2006) and wound
Pesticide bioactivity processed evaluates SOP (insecticide volume), determines sulphur insect amide and Tolfenpyrad single dose LC50With mixture LC50。
The tender point of tea tree is cut during experiment, is immersed in the decoction of preparation up to 5 seconds, is placed in after drying in beaker, meets CO2Fiber crops
Liquor-saturated tea lesser leafhopper adult 30, covers gauze, and experiment sets clear water and is processed as control, and often processing is repeated 4 times, and is put in after processing
In observation ward, the illumination 14h at 27 DEG C of temperature, the inspection result after 3d touches polypide with writing brush, reactionless to be considered as dead worm.
The work borer population and total borer population of each processing are counted, the death rate and corrected mortality (Abbott ' s of each processing is calculated
Formula)；Data analysis statistical is carried out with " DPS data handling systems " V14.50 professional versions, regression straight line, LC is obtained50Value.Use grandson
Yun Peifa (Sun etc., 1960) calculates toxicity index, is calculated by following formula and obtains co-toxicity coefficient：
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.

Can be seen that sulphur insect amide with Tolfenpyrad 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 sulphur insect amide with Tolfenpyrad mixture to tea lesser leafhopper and tool
There is significant synergistic effect.
3rd, preventing and treating tea lesser leafhopper Field information experiment
According to medicine inspecting institute of the Ministry of Agriculture " GB-T 17980.4-2000 pesticide field efficacy medicine tests criterions (one) --- insecticide
The regulation of preventing and treating tea lesser leafhopper " carries out experiment.
Test site：Ningbo City, Zhejiang Province Yinzhou District Qiu Ai towns age villages up to ten thousand.
Test period：19 days~July 10 June in 2014.
Test method：Tea tree, tea lesser leafhopper is based on low instar larvae.
Formulation rate is 750kg/hm2, plant blade face even spraying.4 repetitions, random district's groups arrangement.Adopted per experimental plot
With the 5 points of samplings of interlacing jump method, investigation leaf roll number and total number of sheets.
According to investigation result, leaf roll rate 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).
Preventing and treating tea lesser leafhopper Field information result of the test is listed in Table 2 below.
Table 2：Prevent and treat the field control effectiveness test result of tea lesser leafhopper
HY366 is can be seen that from above-mentioned field control effectiveness test result and energy effectively preventing tea after Tolfenpyrad compounding is small
Greenery cicada, preventive effect is better than comparison medicament.To trial crops safety in scope of medication.
Under summary, substantial amounts of indoor biometricses and field control effectiveness test result show that the Pesticidal combination of the present invention has
State beneficial effect：
(1) compared with single dose, the Pesticidal combination has significant synergistic effect to preventing and treating tea lesser leafhopper, extends holding effect
Phase, improve effect；Using 15%-60%HY366 Tolfenpyrad preparations, 10d reaches to tea lesser leafhopper preventive effect after administration
To 88.4%-91.2%, 20d preventive effects reach 87.4%-91.5% after administration, far above HY366 and Tolfenpyrad single dose
Preventive effect.
(2) times for spraying is reduced, lowers drug cost, environmental pollution and residues of pesticides are reduced；
(3) composition is made up of the active ingredient of different mechanism of action, action site increase, is conducive to overcoming and is delayed evil
Worm is drug-fast to be produced.The present composition is equal to trial crops without obvious harmful effect, and leaf color, growing way etc. are all normal, safety
Property is good, meets the security requirement of pesticidal preparations.
Pesticidal combination of the present invention has good preventive effect to tea lesser leafhopper.
