Abstract
The invention discloses a complex pesticide for preventing and controlling brontispa longissima, which comprises a main agent and an auxiliary agent, the weight percent of the main agent is 0.5-90%, and the weight percent of the auxiliary agent is 10-99.5%; and the main agent is a mixture of pyridaben and dimehypo, and the weight ratio of the pyridaben to the dimehypo is 1: (5-20). The complex pesticide of the pyridaben and the dimehypo can be used for killing the brontispa longissima, the complex cotoxicity coefficient of pyridaben and dimehypo is greater than 120 and synergy is achieved.
Description
Technical field
The present invention relates to a kind of insecticide, specifically, relate to a kind of compounded pesticides that is used to prevent and treat Brontispa longissima.
Background technology
Brontispa longissima is the external pest of a kind of substantial risk property, in 19 kinds of forestry quarantine harmful organisms lists of the up-to-date announcement of the State Administration of Forestry, at the third place.Brontispa longissima has fast, the destructive strong and big characteristics of difficulty of prevention and cure of breeding.Since two thousand two, the insect of Brontispa longissima is engulfing trees, and nearly 1,000,000 cocoanut trees and babassu are encroached on.Caused the economic loss of more than one hundred million units.If these insects can not get effective control, southern coconut palm will be ruined light in have more than is needed several years, and the life of coconut palm farmings up to a million also will be affected.
Summary of the invention
The purpose of this invention is to provide a kind of compounded pesticides that is used to prevent and treat Brontispa longissima efficiently.
To achieve these goals, the present invention adopts following technical scheme:
A kind of compounded pesticides that is used to prevent and treat Brontispa longissima is characterized in that, is made up of host and assistant agent, and its percentage by weight is a host 0.5～90%, assistant agent 10～99.5%; Said host is the mixture of pyridaben and dimehypo, and its weight ratio is: pyridaben: dimehypo=1:5～20.
As preferably, above-mentioned assistant agent is stabilizing agent, auxiliary agent and filler.Said stabilizing agent is acetic acid, phosphoric acid, sal-ammoniac or sulfate of ammoniac; Said auxiliary agent is dodecyl sodium sulfate, sodium lignin sulfonate, dispersant NNO, penetrant t; Said filler is kaolin, diatomite, bentonite, attapulgite, calcium carbonate or sodium bicarbonate.
Compared with prior art, the present invention has following beneficial effect: pyridaben of the present invention and dimehypo compounded pesticides can be used to kill Brontispa longissima, and both composite co-toxicity coefficients have synergistic effect greater than 120.
Embodiment
Embodiment 1: wetting powder
Pyridaben 2%, dimehypo 18%, sodium lignin sulfonate 6%, NNO 4%, adds diatomite and mends to 100%.
Embodiment 2: suspending agent
Pyridaben 1%, dimehypo 19%, calcium lignosulfonate 20%, neopelex 15%, polyvinyl alcohol 15%, bentonite 30%.
Embodiment 3: wetting powder
Pyridaben 1%, dimehypo 20%, sodium lignin sulfonate 5%, NNO 4%, adds diatomite and mends to 100%.
Embodiment 4: suspending agent
Pyridaben 7%, dimehypo 35%, calcium lignosulfonate 10%, neopelex 17%, polyvinyl alcohol 16%, bentonite 15%.
Embodiment 5: compounded pesticides is to the Toxicity Determination of Brontispa longissima
With the Brontispa longissima adult is tested object, adopts infusion process to carry out the virulence test, repeats 4 times, investigates behind the medicine 3 days effect, and the calculation correction lethality is asked the regression equation of drug concentration logarithm-lethality probability value, and the comptibility test of the side of card, obtains LC then
50, calculate the co-toxicity coefficient (CTC) of relative virus force index (TI) and compounded pesticides with reference to the abundant method of Sun Yun.Its result of the test such as table 1.
Table 1 compounded pesticides is to the Toxicity Determination of Brontispa longissima (behind the medicine 3 days)
| Handle | Virulence regression equation | R 2 | LC 50And 95% confidence interval | TI | CTC |
| Embodiment 1 | y = 1.7882x + 2.6137 | 0.9759 | 21.60，19.93-23.42 | 241.18 | 123.45 |
| Embodiment 2 | y = 1.8842x + 2.7681 | 0.9870 | 14.83，13.64-16.13 | 351.28 | 129.31 |
| Embodiment 3 | y = 1.2875x + 3.5272 | 0.9658 | 13.93，12.52-15.49 | 374.02 | 133.01 |
| Embodiment 4 | y = 1.3201x + 3.4681 | 0.9529 | 14.47，13.05-16.04 | 360.06 | 126.61 |
R
2: determination coefficient; TI: relative virus force index; CTC: co-toxicity coefficient.CTC had the effect of subtracting effect less than 80 o'clock between the two; Greater than having synergistic effect at 120 o'clock; It in the time of between 80～120 summation action.
The result shows that the compounded pesticides of pyridaben and dimehypo can be used to kill Brontispa longissima, and both composite has synergistic effect.
