Abstract
The invention relates to an insecticide composition in the field of pesticide compounding, the effective components of the insecticide composition are thiacloprid-amide and chlorpyrifos, wherein the mass ratio of the thiacloprid-amide to the chlorpyrifos is (1-80): (80-1). The insecticide composition has a very remarkable synergism on Lepidoptera, such as plutella xylostella, beet armyworm, cotton bollworm, prodenia litura, striped rice borer and the like, and sucking pests, such as rice planthopper, lesser green leaf hopper and the like. Meanwhile, the insecticide composition is safe to environment, efficient and low-toxic, is not easy to generate resistance, and is an invention creation with a better promoting function to the agricultural production. The insecticide composition can be prepared into formulations such as emulsion in water, water dispersible granules, a suspending agent, wettable powder, microemulsion, missible oil and the like by using a known method in the technical field.
Description
Technical field
The present invention relates to the agriculture chemical compounding technical field, be specifically related to a kind of contain the thiophene insect amide have a synergistic effect Pesticidal combination, be used to prevent and treat the resistant insect on the crops.
Background technology
In agricultural production, the chemical control damage by disease and insect is an important means in the agricultural production.In the chemical control process, the problem of easy generation is the generation and the development of germ and pest resistance.It is short to be easy to generate the common breeding cycle of resistant insect on the agricultural, and breeding amount is big, and generation overlap is obvious.Will cause very large obstacle in the anti-area of height for agricultural production, therefore, evade or the generation that slows down the insect pest resistance has very important significance for agricultural production.
The thiophene insect amide is a kind of novel adjacent heterocycle benzamide compound.Have very strong permeability, medicament can enter into xylem by stem's epidermal cell.According to test, this medicament has fabulous preventive effect for lepidoptera pest, and is long for the insect pest control time.Have higher selectivity simultaneously, for the beneficial organism low toxicity, environmentally safe.
Chlopyrifos is newer organophosphorus insecticide, this medicament have tag, stomach toxicity and fumigation action.Quick-acting is good, in soil the residence time longer, underground insect is had preventive effect preferably.Chlopyrifos is applicable to multiple pests with chewing mouthparts and the sucking pest on paddy rice, cotton, fruit tree, the vegetables tea tree.
Summary of the invention
Based on above situation, the object of the present invention is to provide a kind of agricultural insecticide composition, this Pesticidal combination is characterized in that with thiophene insect amide (A) and chlopyrifos (B) be that active ingredient is mixed, and the control of sucking pest such as lepidoptera pest such as diamond-back moth, prodenia litura, cotton bollworm, beet armyworm, striped rice borer and rice fulgorid, tea lesser leafhopper, Tetranychus cinnabarinus, two spotted spider mite has good synergistic effect.
Pesticidal combination of the present invention is characterized in that the mass ratio of effective constituents A and B is 1～80: 80～1.
Pesticidal combination of the present invention is characterized in that through the toxicity test experiment, the mass ratio of effective constituents A and B is preferably 1～40: 45～5.
The formulation that described Pesticidal combination of the present invention can be prepared according to the known method of those skilled in the art of the present technique is aqueous emulsion, water-dispersible granules, suspending agent and wetting powder.
Described thiophene insect amide and the chlopyrifos gross mass content in preparation is 5%-80%, preferred 6%-50%.
Pesticidal combination of the present invention has obvious synergistic effect, can reduce effective ingredient consumption, delays the generation of pest resistance to insecticide, and can be used for the improvement of resistant insect.Be particularly suitable for being used to prevent and treat suckings pest such as the lepidoptera pests such as diamond-back moth, prodenia litura, cotton bollworm, beet armyworm, striped rice borer of vegetables and plant hopper, tea lesser leafhopper.
The different proportioning co-toxicities of thiophene insect amide with chlopyrifos
1.1 reagent agent
The former medicine of 96% thiophene insect amide, the former medicine of 97% chlopyrifos, above-mentioned former medicine provides by sea, Qingdao research and development centre of rel medicine company group.
1.2 indoor examination worm source
The indoor beet armyworm of for many generations raising, indoor conditions: temperature (26 ± 2) ℃.Relative moisture 70% ± 5%, periodicity of illumination 16/8h (L/D).
1.3 single agent assay method
The polypide immersion method is adopted in this test.At first the mother liquor with thiophene insect amide, chlopyrifos is diluted to 5 concentration, places beaker standby respectively.With writing brush the beet exigua larvae at 3 initial stages in age of physiological status unanimity is swept lightly and to soak in the worm device, will soak the worm device and immerse in the soup, shake gently, take out behind the 5s, wash dried polypide and unnecessary peripherally soup with blotting paper rapidly.It is 26 ℃ that larva after the processing places temperature, and relative moisture is in 70% the intelligent insectary.Every concentration repeats 3 times, and 20 larvas of every repetition are established blank simultaneously, and is doomed dead respectively at 48h inspection behind the medicine, calculates lethality, corrected mortality, obtains virulence regression equation and calculate LC
50The control group lethality is being efficiency test below 10%.
1.4 the joint toxicity measuring method of different proportionings,
According to preliminary experiment both total active ingredient 28% is set, set ratio is that m (chlopyrifos): m (thiophene insect amide) was respectively 10.2: 17.8,10.4: 17.6,10.6: 17.4,10.8: 17.2,11.0: 17.0.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 the thiophene insect amide is the standard medicament, and its toxicity index is 100):
The LC of the toxicity index of chlopyrifos (TI)=thiophene insect amide
50The LC of/chlopyrifos
50* 100
The LC of actual toxicity index (ATI)=thiophene insect amide of M
50The LC of/M
50* 100
TI * P chlopyrifos of the TI of theoretical toxicity index (TTI)=thiophene insect amide of M * P thiophene insect amide+chlopyrifos
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In the formula:
M is a chlopyrifos and the mixture of the different proportionings of thiophene insect amide
The P chlopyrifos is chlopyrifos shared ratio in mixture
P thiophene insect amide is thiophene insect amide shared ratio in mixture
2.1 toxicity test result
Table 1 thiophene insect amide, chlopyrifos are to the indoor measurement result of beet armyworm
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, chlopyrifos wherein: the thiophene insect amide is that 10.4: 17.6 synergistic effect is the most obvious, co-toxicity coefficient is 156.49, and secondly be chlopyrifos: the thiophene insect amide is 10.6: 17.4, and co-toxicity coefficient is 144.48.Result of the test shows, chlopyrifos, two kinds of medicaments of thiophene insect amide all have higher activity to beet armyworm under indoor conditions, the result of the test of different proportion proportioning shows, in active ingredient ratio chlopyrifos: the thiophene insect amide is 10.2: 17.8,10.4: 17.6,10.6: 17.4,10.8:, all show stronger synergistic effect at 17.2,11.0: 17.0 o'clock, wherein with chlopyrifos: the thiophene insect amide is 10.4: 17.6～10.6: 17.4 o'clock, and synergistic effect is best.Suggestion is carried out further field control effectiveness test to the mixture preparation of 10.4: 17.6 left and right sides scopes of suitable proportion, to estimate its field practical application effect.
