Description
Technical field
The invention belongs to field of agrochemicals, relate to a kind of Pesticidal combination and application thereof, especially a kind of is the Pesticidal combination of main active component with Imidacloprid and spiral shell worm ethyl ester.
Background technology
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 the pest control with insecticide miticide is composite or be mixed to have to enlarge and prevent spectrum, improve control efficiency, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay pest 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.
Imidacloprid (imidacloprid): (E)-1-(2-chloro-1,3-thiazoles-5-ylmethyl)-3-methyl-2-nitroguanidine
Clear crystal has faint smell, 143.8 ℃ of fusing points (crystal form 1) 136.4 ℃ (form 2), vapour pressure 0.2 μ Pa (20 ℃), density 1.543 (20 ℃), KowlogP=0.57 (22 ℃), solvability water 0.51g/L (20 ℃), carrene 50-100, isopropyl alcohol 1-2, toluene 0.5-1, n-hexane＜0.1 (g/L, 20 ℃), pH5-11 is stable.The nitro-methylene-type systemic insecticide is the acting body of nicotinic acid acetylcholinesterase acceptor, and it is malfunctioning to disturb the pest movements nervous system that chemical signal is transmitted, no cross resistance problem.Be used to prevent and treat sucking pest and resistant strain thereof.
Spiral shell worm ethyl ester (spirotetramat): 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.

Embodiment: the different proportioning co-toxicities of spiral shell worm ethyl ester with Imidacloprid
Further the present invention is made an explanation by following examples, but scope of the present invention is not limited to following examples.
1.1 reagent agent
The former medicine of 95% spiral shell worm ethyl ester (imidacloprid), the former medicine of 95% Imidacloprid (carbosulfan), the green source of the Yang Zhou of Jiangsu Province biochemical industry Co., Ltd provides.
1.2 indoor examination worm source
Rice leaf roller system gathers from the field, and supplies to try indoor the raising to 3 ages with rice seedling.Indoor conditions: temperature (25 ± 2) ℃.Relative moisture 65% ± 5%, periodicity of illumination 12/12h (L/D).
1.3 single agent assay method
Adopt rice stem infusion process, take the healthy and strong consistent booting rice strain in mid-term, clean, be cut into the long company's root rice stem of 15cm, drying in the air in the place, cool place does not have washmarking to the surface, standby.According to the preliminary experiment result, with former medicinal small amount of acetone dissolving, be diluted to 5 variable concentrations with 0.1% Tween solution again, with the clear water is contrast, place the rice stem of getting ready the soup of variable concentrations to soak 30s respectively, dry slightly after the taking-up, encase root, put into test tube (high 180mm * diameter 18mm) with the rayon balls that soaks with clear water, the criteria for selection unanimity 3 age nymph, put into test tube, 20 of every pipes, the individuality of rejecting mechanical damage, supply 20, seal with wet gauze the upper end, and each concentration repeats 3 times, totally 60.Connecing test tube behind the worm, to put into temperature be that 26 ℃, relative moisture are 70% insectary, checks dead, the borer population of living behind the 48h, calculates lethality, and proofread and correct with the lethality of contrast, asks virulence regression equation, the lethal dose of 50 (LC with probability value analytical method then
50) and correlation coefficient (r).
1.4 the joint toxicity measuring method of different proportionings,
According to total active ingredient is 36%, and both mass ratioes are that m (Imidacloprid): m (spiral shell worm ethyl ester) was respectively 1: 1,2: 1, and 3: 1,4: 1, be Imidacloprid at 5: 1: spiral shell worm ethyl ester is 18%: 18%, 24%: 12%, 27%: 9%, 28.8%: 7.2%, 30%: 6%.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 Imidacloprid (TI)=spiral shell worm ethyl ester
50The LC of/Imidacloprid
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 Imidacloprid of the TI of the theoretical toxicity index (TTI) of M=spiral shell worm ethyl ester * P spiral shell worm ethyl ester+Imidacloprid
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In the formula:
M is an Imidacloprid and the mixture of the different proportionings of spiral shell worm ethyl ester
The P Imidacloprid is Imidacloprid 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, Imidacloprid are to the indoor measurement result of rice leaf roller
| Handle title | Proportioning | Virulence regression equation (Y=a+bx) | The correlation coefficient r value | LC 50(mg/L) | Co-toxicity coefficient (CTC) |
| Spiral shell worm ethyl ester | - | Y＝0.4497+6.0937x | 0.9717 | 5.69 | - |
| Imidacloprid | - | Y＝2.47+1.7553x | 0.9802 | 27.63 | - |
| Imidacloprid: spiral shell worm ethyl ester | 1∶1 | Y＝3.5857+1.6025x | 0.9055 | 7.63 | 123.60 |
| Imidacloprid: spiral shell worm ethyl ester | 2∶1 | Y＝2.8571+2.3873x | 0.9258 | 7.90 | 153.10 |
| Imidacloprid: spiral shell worm ethyl ester | 3∶1 | Y＝2.9710+2.2576x | 0.9643 | 7.92 | 177.52 |
| Imidacloprid: spiral shell worm ethyl ester | 4∶1 | Y＝3.5428+1.4068x | 0.9627 | 10.86 | 143.65 |
| Imidacloprid: spiral shell worm ethyl ester | 5∶1 | Y＝3.4708+1.3003x | 0.9882 | 13.11 | 128.30 |
As can be seen from the table, in being mixed of different proportion, its co-toxicity coefficient is all greater than 120, show certain synergistic effect, Imidacloprid wherein: spiral shell worm ethyl ester is that 3: 1 synergistic effect is the most obvious, co-toxicity coefficient is 177.52, and secondly be Imidacloprid: spiral shell worm ethyl ester is 2: 1, and co-toxicity coefficient is 153.10.Result of the test shows, Imidacloprid, two kinds of medicaments of spiral shell worm ethyl ester all have higher activity to rice leaf roller under indoor conditions, the result of the test of different proportion proportioning shows, in active ingredient ratio Imidacloprid: spiral shell worm ethyl ester is 1: 1,2: 1,3: 1,4: 1,, all show stronger synergistic effect at 5: 1 o'clock, wherein with Imidacloprid: spiral shell worm ethyl ester is 2: 1～3: 1 o'clock, and synergistic effect is best.Suggestion is carried out further field control effectiveness test to the mixture preparation of 3: 1 left and right sides scopes of suitable proportion, to estimate its field practical application effect.
