2nd, the mensure of biological activity
In order to further appreciate that the virulence of active component 419 and clothianidin or the compositionss of MTI-446, joined in a large number
Square 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.
Raise worm kind (27 DEG C, 14h illumination/d) from interior with rice seedling throughout the year.Select indoor feeding low age, size
Consistent Brown Planthopper (nilaparvata lugens (stal)) nymph is for experiment.Using dip method.By target insect
After immersion medicinal liquid 5～10s, suck unnecessary medicinal liquid with filter paper, test worm is gone to and raises under normal condition, test sets without medicament
Corresponding organic solvent is processed as compareing, and often processes and is repeated 4 times, and often repeats to soak worm 20～30, inspection result after 24h, with brush pen
Touch polypide, reactionless be considered as dead worm.Count the borer population alive of each process and total borer population, calculate mortality rate and the correction of each process
Mortality rate (abbott ' s formula)；Carry out data analysis statistical with " dps data handling system " v14.50 professional version, obtain recurrence
Straight line, lc50Value.Calculate toxicity index with the abundant method of Sun Yun (sun etc., 1960), be calculated co-toxicity coefficient by following formula:
Content (%) in mixed for the toxicity index × a of theoretical mixed toxicity index (tti)=a
Content (%) in mixed for the toxicity index × b of+b
Act on the criteria for classifying according to ny/t11547.7-2006 insecticide combination, when co-toxicity coefficient is more than 120, show this
Plant mixture and there is potentiation；And co-toxicity coefficient be less than 80 when, show that this mixture has antagonism；And co-toxicity coefficient is more than
80 less than 120 when, show that this mixture has summation action.
Active component 419 and clothianidin different ratio mixture see table 1 to the Toxicity Determination result of planthopper.
Table 1: " 419 " compound the Toxicity Determination result to planthopper with clothianidin
From above-mentioned Toxicity Determination result can be seen that active component 419 with clothianidin in weight than 1:1～1:20's
In the range of compounding when, its co-toxicity coefficient (ctc) is all higher than 120, significantly shows collaborative increasing especially in the range of 1:8～1:20
Effect, illustrates that active component 419 is had significant synergies to water rice hopper with clothianidin mixture.
Additionally, active component 419 its lc when being used alone50Larger, can effectively reduce thiophene after compounding with clothianidin
The lc of worm amine50, equally show obvious Synergistic result in the range of 1:8～1:20.
Active component 419 and MTI-446 different ratio mixture see table 2 to the Toxicity Determination result of planthopper.
Table 2: " 419 " compound the Toxicity Determination result to planthopper with MTI-446
From above-mentioned Toxicity Determination result can be seen that active component 419 with MTI-446 in weight than 1:1～1:20's
In the range of compounding when, its co-toxicity coefficient (ctc) is all higher than 120, especially shows more prominent in the range of 1:8～1:20, and work be described
Property composition 419 is had significant synergies to water rice hopper with dinotefuran mixed.
3rd, 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
The regulation of preventing and treating water rice hopper " carries out test.
Test method: Rise's boot period dispenser is once.Rice hoppers are based on low instar nymphs.
Formulation rate is 750kg/hm2, plant blade face even spraying.Plot area 25m2, 4 repetitions, random district's groups arrangement.
The 10 points of samplings of the parallel jump method in every experimental plot, investigate 2 clumps at every, investigate 20 clumps altogether, investigate the every 2 clumps borer populations alive taking.
According to survey result, calculate Revision insect recluced rate and preventive effect according to formula below (1) with (2).Test data adopts Deng
Ken Shi duncan's new multiple range method (dmrt) carries out statistical analysiss.
Water rice hopper field control effectiveness test result prevented and treated by table 3
From above-mentioned field control effectiveness test result can be seen that 419 compound with clothianidin or MTI-446 after can effectively prevent and treat
Water rice hopper, its 7 days preventive effects and 14 days preventive effects are significantly better than the effect of single dose, reduce formulation rate therefore, it is possible to effective, and with
To trial crops safety in the range of medicine.
In sum, under indoor biometricses and field control effectiveness test result show that agricultural pesticide composition of the present invention has
State beneficial effect:
1st, compared with single dose, this Pesticidal combination has significant potentiation to preventing and treating planthopper, extends the lasting period, carries
High effect；
2nd, reduce times for spraying, lower drug cost, reduce environmental pollution and pesticide residues；
3rd, compositionss are made up of the effective ingredient of different mechanism of action, and action site increases, and are conducive to overcoming and delay to do harm to
The drug-fast generation of worm., to trial crops all no substantially harmful effects, leaf color, growing way etc. are all normal, safety for the present composition
Property is good, meets the security requirement of pesticidal preparations.
Pesticidal combination of the present invention has good preventive effect to water rice hopper.
