Description

A kind of Pesticidal combination that contains spiral shell worm ethyl ester and Biphenthrin
Technical field
The invention belongs to the agriculture chemical compounding field, relate to a kind of Pesticidal combination and application thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with spiral shell worm ethyl ester and Biphenthrin.
Technical background
In the real process of agricultural production, use chemical agent and be the most effectively means of control plant pest, but be the generation of pest resistance to insecticide by the problem that the chemical control insect is easy to generate most.And long-term use single chemical insecticide continuously high dose, cause a series of problems such as residual, environmental pollution of medicament easily.Reasonably chemical insecticide is composite or be mixed and have the expansion insecticidal spectrum, improve control efficiency, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay insect evil mite drug resistance and positive characteristics such as drug-fast generation and development, insecticidal/acaricidal agent is composite or to be mixed be one of the effective method the most that addresses the above problem.Exploitation new product insecticide price is constantly soaring, and by contrast, exploitation is efficient with research, low toxicity, low-residual composite be mixed have small investment, the lead time is short and be subjected to domestic and international attention, strengthens the development dynamics one after another.
Spiral shell worm ethyl ester (spirotetramat): 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2, the 5-xylyl)-1-azaspiro [4,5]-last of the ten Heavenly stems-3-alkene-2-ketone
Former medicine outward appearance is a white powder, does not have special smell, and the preparation outward appearance is a tool fragranced white suspension.142 ℃ of molten points, solvability (20 ℃) water 33.4mg/L, organic solvent: ethanol 44.0mg/L, n-hexane 0.055mg/L, toluene 60mg/L, carrene>600mg/L, acetone 100-120mg/L/ ethyl acetate 67mg/L, dimethyl sulfoxide (DMSO) 200-300mg/L.235 ℃ of decomposition temperatures. stability is better.Be a kind of novel tetronic acid insecticides, insecticidal spectrum is wide, and the lasting period is long.It is that fatty biosynthesis by interference insect causes larva death, reduces the fertility of adult.Because its unique mechanism of action can be prevented and treated the insect that existing insecticide is produced resistance effectively, can be used as the important kind of nicotinic insecticide resistance management simultaneously.
Biphenthrin (bifenthrin), (1R, S)-cis (Z) 2,2-dimethyl-3-(2-chloro-3,3,3-three fluoro-1-acrylic) cyclopropane-carboxylic acid-2-methyl-3-phenyl benzyl ester

Embodiment: the different proportioning co-toxicities of spiral shell worm ethyl ester with Biphenthrin
1.1 reagent agent
The former medicine of 95% spiral shell worm ethyl ester, the former medicine of 98% Biphenthrin, Jiangsu Changlong Chemical Co provides.
1.2 indoor examination worm source
Gathering the citrus psylla adult from the kamuning of the urban district greenbelt that seldom sprays medicine, is that 0.45mm nets indoor kamuning and bred for 7 generations in the aperture.
1.3 single agent assay method
Adopt the unified in the world drop method of doing the rice fulgorid toxicity test.Accurately take by weighing reagent agent, with a small amount of 25% acetone (because the wood louse adult is very responsive to acetone, can make the lethality of wood louse adult surpass 30% when making blank with analytically pure acetone soln, so with pure water with acetone diluted to 25%) dissolve former medicine, be made into into 5 series concentration of equal difference more respectively with the 0.1% Tween 80 aqueous solution, make blank with 25% acetone soln, repeat 3 times, repeat 10 adults at every turn.Use CO during processing 2After the anesthesia, rapidly with 0.036 micro-drop instrument with medicine liquid droplet on the pronotary of wood louse adult, every worm is dripped 0.036ul, blank drips 0.036ul 25% acetone soln, the illumination box of putting into the culture dish of the tender tip of kamuning after the processing and inserting temperature (25~1) ℃, 24h observes dead borer population, borer population alive behind the medicine, calculates lethality and corrected mortality, carries out data with the DPS Biological Statistic Analysis Software and handles.
1.4 the joint toxicity measuring method of different proportionings,
According to total active ingredient is 24%, and both mass ratioes are that m (Biphenthrin): m (spiral shell worm ethyl ester) was respectively 1: 2,2: 1, and 3: 2,4: 1, be Biphenthrin at 5: 3: spiral shell worm ethyl ester is 8%: 16%, 16%: 8%, 14.4%: 9.6%, 19.2%: 4.8%, 15%: 9%.Adopt above-mentioned 1.3 methods to carry out toxicity test, calculate LC 50, and press the abundant method of Sun Yun and calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (with spiral shell worm ethyl ester is the standard medicament, and its toxicity index is 100):
The LC of the toxicity index of Biphenthrin (TI)=spiral shell worm ethyl ester 50The LC of/Biphenthrin 50* 100
The LC of the actual toxicity index (ATI) of M=spiral shell worm ethyl ester 50The LC of/M 50* 100
TI * P the Biphenthrin of the TI of the theoretical toxicity index (TTI) of M=spiral shell worm ethyl ester * P spiral shell worm ethyl ester+Biphenthrin
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In the formula:
M is a Biphenthrin and the mixture of the different proportionings of spiral shell worm ethyl ester
The P Biphenthrin is Biphenthrin shared ratio in mixture
P spiral shell worm ethyl ester is spiral shell worm ethyl ester shared ratio in mixture
2.1 toxicity test result
Spiral shell worm ethyl ester, Biphenthrin are to the indoor measurement result of citrus psylla
As can be seen from the table, in being mixed of different proportion, its co-toxicity coefficient is all greater than 120 except 5: 3 o'clock, and all show certain synergistic effect, wherein Biphenthrin: spiral shell worm ethyl ester is that 2: 1 synergistic effect is the most obvious, and co-toxicity coefficient is 147.52.Result of the test shows, Biphenthrin, two kinds of medicaments of spiral shell worm ethyl ester all have higher activity to the oranges and tangerines wood louse under indoor conditions, the result of the test of different proportion proportioning shows, in active ingredient ratio Biphenthrin: spiral shell worm ethyl ester is 1: 2,2: 1,3: 2,4: 1,, all show stronger synergistic effect at 5: 3 o'clock.Suggestion is carried out further field control effectiveness test to the mixture preparation of 2: 1 left and right sides scopes of suitable proportion, to estimate its field practical application effect.
3 field trials control paddy rice rice leaf roller, the oranges and tangerines wood louse
3.1 field experiment control paddy rice rice leaf roller
3.1.1 test method
Tested on August 20th, 2009 to September 10 and carry out in Xiangyin, Hunan institute of agricultural sciences experimental field.Tested on August 20th, 2009 and carry out routine to water spray by each processing design concentration.Spraying equipment is a WF-16 type knapsack hand sprayer, and shower nozzle is single fan nozzle, and operating pressure is 0.2-0.4Mpa, and spray amount is 0.36-0.48L/min, carries out the routine spraying, makes every effort to evenly thoughtful during the spray medicine.The field rice leaf roller is 1~2 instar larvae peak period during dispenser.Every 667m 2To the water yield is 50kg.
Duration of test weather is good, and daily mean temperature is 19.8~29.1 ℃.Dispenser did not have rain the same day.
3.1.2 investigation method
Adopt 5 point samplings, 5 points are selected in every sub-district, every sub-district 20m 2, 5 clumps every, investigate 25 clumps of paddy rice altogether.Before dispenser and after the dispenser the 3rd, 7d investigates whole blades of 25 clumps respectively, wins all the old and new worms bags, the residual borer population alive of stripping bag record then calculates go down rate and proofread and correct preventive effect of insect population; 20d investigated the leaf roll number when present age, harm was finalized the design behind medicine, calculated leaf roll rate and preventive effect.Notice that the viewing test chemicals treatment has or not poisoning to paddy rice.
3.1.3 drug effect computational methods.
