Description
[technical field]
The invention belongs to technical field of pesticide.More particularly it relates to an containing N-(cyanoalkyl) Benzoylamide
Compounds and the agricultural pesticide composition of pymetrozine, further relate to the purposes of described agricultural pesticide composition.
[background technology]
Planthopper is the main insect of Oryza sativa L., and its harm occurred has hiding, fulminant and destructive feature.
Planthopper is a kind of migratory pest, usually causes the significant loss of crop, the Rice Production of serious harm China.Along with chemistry
Constantly using of medicament, resistance problem becomes increasingly conspicuous, and in agricultural production real process, pest resistance to insecticide problem is impact evil
The key factor of worm prevention effect.Being carried out by difference effective ingredient compounding can be that insect resists with expanding prevention spectrum and raising preventive effect
Property administer effective measures.
N-(cyanoalkyl) benzamide compound has good prevention effect to Oryza sativa L. rice leaf roller, striped rice borer, but
The prevention effect of water rice hopper can not be reached preferable effect.Chinese patent application CN 201010293074.0, denomination of invention

Two, bioactive mensuration
In order to further appreciate that the virulence of active component 419 and pymetrozine composition, carry out a large amount of formulation screening test.
Pesticidal combination biological activity determination of the present invention is as follows:
According to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.6-2006 and agricultural
Industry standard NY/T1154.7-2006), measure single dose LC50With mixture LC50。
Select indoor throughout the year with rice seedling raising worm kind (27 DEG C, 14h illumination/d).Select indoor feeding low age, size
Consistent Brown Planthopper (Nilaparvata lugens (Stal)) nymph is for experiment.Use dip method.By target insect
After immersing medicinal liquid 5～10s, sucking unnecessary medicinal liquid with filter paper, go to examination worm raise under normal condition, test sets without medicament
Corresponding organic solvent is processed as comparison, often processes and is repeated 4 times, and often repeats to soak worm 20～30, checks result, with brush pen after 24h
Touch polypide, reactionless be considered as dead worm.Add up each borer population alive processed and total borer population, calculate mortality rate and the correction of each process
Mortality rate (Abbott ' s formula)；Carry out data analysis statistical by " DPS data handling system " V14.50 professional version, obtain recurrence
Straight line, LC50Value.Calculate toxicity index by the abundant method of Sun Yun (Sun etc., 1960), following formula be calculated co-toxicity coefficient:
Toxicity index × the A of theoretical mixed toxicity index (TTI)=A content (%) in mixed
Toxicity index × the B of+B content (%) in mixed
When co-toxicity coefficient is more than 120, show that this mixture has potentiation；And co-toxicity coefficient less than 80 time, show
This mixture has antagonism；And co-toxicity coefficient more than 80 less than 120 time, show that this mixture has summation action.
Active component 419 and pymetrozine different ratio mixture see table 1 to the Toxicity Determination result of planthopper.
Table 1:419 and the Pyraphione compound Toxicity Determination result to planthopper
From above-mentioned Toxicity Determination result it can be seen that 419 answer in the range of weight ratio 1:1～1:20 with pymetrozine
Timing, its co-toxicity coefficient (CTC) is all higher than 120, illustrates that water rice hopper is had significantly by active component 419 and pymetrozine mixture
Potentiation.
Three, preventing and treating water rice hopper Field information test
According to medicine inspecting institute of the Ministry of Agriculture " GB-T 17980.4-2000 pesticide field efficacy medicine test criterion (one) insecticide
Preventing and treating water rice hopper " regulation carry out test.
Test method: Rise's boot period dispenser is once.Rice hoppers is based on low instar nymphs.
Formulation rate is 750kg/hm2, plant blade face even spraying.Plot area 25m2, repeating for 4 times, random district group arranges.
Every experimental plot 10 samplings of parallel jump method, investigate 2 clumps at every, and investigation 20 clumps, investigates every 2 clumps of borer populations alive taken altogether.
According to survey result, calculate Revision insect recluced rate and preventive effect according to formula below (1) with (2).Test data uses Deng
Ken Shi duncan's new multiple range method (DMRT) carries out statistical analysis.
Water rice hopper field control effectiveness test result prevented and treated by table 2
From above-mentioned field control effectiveness test result it can be seen that can effectively preventing after active component 419 and Pyraphione compound
Water rice hopper, preventive effect is better than compareing medicament, shows the reduction of on the one hand effective ingredient consumption, on the other hand 7 days preventive effects after medicine
All it is significantly increased with 14 days preventive effects.To trial crops safety in scope of medication.
In sum, under indoor biometrics and field control effectiveness test result show that agricultural pesticide composition of the present invention has
State beneficial effect:
1, compared with single dose, this Pesticidal combination has significant potentiation to preventing and treating planthopper, extends the lasting period, carries
High effect；
2, reduce times for spraying, lower drug cost, reduce environmental pollution and pesticide residues；
3, compositions is made up of the effective ingredient of different mechanism of action, and action site increases, and is conducive to overcoming and delay evil
The drug-fast generation of worm.The present composition is equal without obvious harmful effect to trial crops, 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 water rice hopper.
