Abstract
The invention discloses a novel synergistic pesticide composition which comprises flutolanil and flonicamid according to a mass ratio of 100:1-1:100. The novel synergistic pesticide composition provided by the invention has a certain synergistic effect on prevention and control of crop diseases and pests, and has the advantages of delaying the development of resistance, prolonging the service life of a medicament, preventing and controlling various pests at a time, and reducing the labor cost.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specifically related to a kind of Novel synergistic composition pesticide.
Background technology
In agriculture plant protection; with the disease pest and weed comprehensive regulation for principle, inevitably this A Yong agricultural chemicals reduces the harm of disease pest and weed, improves crop yield and quality; agricultural chemicals, as the important agricultural material product of a class, has the history of the research, development and production application of decades in China.First, bio-diversity makes the pest population in damage to crops and gardens constantly change, and the requirement for pesticide control is more and more higher; Secondly, the chronic administration of agricultural chemicals makes pest develop immunity to drugs, this just need to develop more efficient, safety, with eco-friendly pharmaceutical preparations, to meet the needs of plant protection.
Summary of the invention
First object of the present invention is to provide a kind of Novel synergistic composition pesticide, comprises flutolanil and flonicamid that quality proportioning is 100:1 ~ 1:100.
The quality proportioning of described flutolanil and flonicamid is 25:1 ~ 1:1.
In described composition pesticide, the gross mass percentage composition of flutolanil and flonicamid is 30% ~ 80%, all the other auxiliary elements allowed for pesticidal preparations.
Described composition pesticide is mixed with microemulsion, aqueous emulsion, suspending agent or wetting powder.
Second object of the present invention is to provide this application of Novel synergistic composition pesticide in controlling crop diseases and insect pests.
In the present invention, flutolanil and the composite rear control to diseases and pests of agronomic crop of flonicamid have certain synergistic effect; Delaying drug resistance develops, and extends medicament service life; Disposablely prevent and treat various pests, reduce costs.
embodiment:
Below in conjunction with concrete case study on implementation, the present invention is described in further detail:
(1) formulation Example
Formulation Example 1:
Flutolanil 100 parts
Flonicamid 1 part
Xanthans 0.3 part
Stabilizing agent 0.7 part
Formulation Example 2:
Flutolanil 25 parts
Flonicamid 1 part
Xanthans 3 parts
Stabilizing agent 5 parts
Formulation Example 3:
Flutolanil 10 parts
Flonicamid 10 parts
Xanthans 8 parts
Stabilizing agent 18 parts
Formulation Example 4:
Flutolanil 1 part
Flonicamid 100 parts
Xanthans 3 parts
Stabilizing agent 8 parts
(2) Application Example
With cotton tetranychid for experimental subjects, adopt leaf disc spray, to measure in this compound pesticide composition flutolanil and flonicamid by the synergistic effect size of different proportion.
According to the CTC value of the abundant method calculation composition of Sun Yun, when CTC is not more than 80, composition shows as antagonism, and when CTC is greater than 80 and is less than 120, composition shows as summation action, and when CTC is more than or equal to 120, composition shows as synergistic effect.
Actual measurement toxicity index (ATI)=(standard agent LC
50/ reagent agent LC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI) × 100/ mixture
The Toxicity Determination of table 1 compound pesticide composition on cotton tetranychid
| Flutolanil: flonicamid (mass ratio) | LC 50 | ATI | TTI | CTC |
| 1:0 | 5.5 | 321.5 | ||
| 0:1 | 11.5 | 109.3 | ||
| 100:1 | 9.9 | 120.6 | 90.2 | 133.7 |
| 25:1 | 5.8 | 355.7 | 280.1 | 127.0 |
| 1:1 | 3.2 | 555.2 | 451.3 | 123.0 |
| 1:100 | 4.1 | 425.8 | 332.0 | 128.3 |
Measurement result indicate flutolanil and flonicamid composite after, concerning cotton tetranychid between composite scope 100:1 ~ 1:100, show synergistic effect, co-toxicity coefficient CTC is more than 120.
