Summary of the invention
In order to satisfy the needs of pesticide producing, take full advantage of two kinds of active components be mixed the synergistic effect that produces, improve preventive effect, reduce agricultural cost and delay the generation of pest resistance to insecticide, the present invention proposes the composite Pesticidal combination that contains Diacloden and carbosulfan.
The object of the present invention is achieved like this: a kind of Pesticidal combination that contains Diacloden and carbosulfan, comprise effective active component, auxiliary agent and filler, and the weight hundred of effective active composition Diacloden and carbosulfan is than being 1~60: 80~1.
The described Pesticidal combination that contains Diacloden and carbosulfan, the percentage by weight of Diacloden and carbosulfan are 1~40: 60~5.
The described Pesticidal combination that contains Diacloden and carbosulfan, the percentage by weight of Diacloden and carbosulfan are 5~15: 40~5.
Described Diacloden and the carbosulfan insecticidal composite of containing, the percentage by weight of Diacloden and carbosulfan is 5~10: 40~10.
Described Diacloden and the carbosulfan insecticidal composite of containing, the optimum activity proportioning of Diacloden and carbosulfan is 5: 1~1: 15, preferred proportioning is 1: 1~1: 10.
The described Pesticidal combination that contains Diacloden and carbosulfan adds conventional auxiliary agent by method well-known in the art, can be made into wetting powder, water dispersible granules, microcapsule suspending agent, aqueous emulsion, microemulsion.
The described Pesticidal combination that contains Diacloden and carbosulfan is mainly used in anti-eliminating aphis, scale insect, trialeurodes vaporariorum, rice fulgorid, thrips and striped flea-beetle.
The invention has the advantages that:
(1) Diacloden and carbosulfan composite after, fully different to the mechanism of action of target pest, both are composite to have notable synergistic and lasting effect;
(2) enlarged insecticidal spectrum, aphid, thrips, rice fulgorid have been had special efficacy;
(3) reduce the dosage of agricultural chemicals, reduced the residual quantity of agricultural chemicals on crop, alleviated environmental pollution;
(4), insect good to person poultry safety, Environmental compatibility is difficult for developing immunity to drugs.
Embodiment
To further instruction of the present invention, the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.First by Toxicity Determination, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC<80 are antagonism, and 80≤CTC≤120 are summation action, and CTC>120 are synergistic effect, on this basis, carry out field trial again.
Application Example one
For the examination insect: cotton aphid, for subsequent use after 3 generations of artificial feeding.
Test medicine: agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
Experimental scheme: effective lethal concentration scope of determining the former medicine of Diacloden, the former medicine of carbosulfan and the two different proportioning mixture through preliminary experiment, each medicament designs respectively five gradient concentrations by active constituent content and processes, and does contrast with the space management that does not contain former medicine.
Test method: respectively the mother liquor of Diacloden, carbosulfan and each mixed agent is diluted to above 5 series concentration during test, places respectively beaker for subsequent use.Adopt and to soak first the method that connects worm behind the leaf, the fresh cotton floral leaf of the same size that does not contact any medicament soaked in the liquid that configures behind the 5s take out, naturally dry, put into insect box, then connect for the examination aphid, under 25 ℃ of conditions, raise, every processing repeats for 3 times, every to repeat used examination borer population be 20, establishes simultaneously blank, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is considered as invalid test greater than 10%.Computing formula is as follows:
The cotton aphid corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates thus the value of every kind of medicament.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (take Diacloden as the standard medicament, its toxicity index is 100):
TI * the P of the theoretical toxicity index (TTI) of M=Diacloden
DiaclodenTI * the P of+carbosulfan
Carbosulfan
In the formula: M is the mixture of different proportionings
P
CarbosulfanBe carbosulfan shared ratio in composition
P
DiaclodenBe Diacloden shared ratio in composition
Result of the test is as shown in table 1:
The different proportionings from carbosulfan of table 1 Diacloden are to the toxicity test of cotton aphid
As shown in Table 1, Diacloden and carbosulfan and composite product are to cotton aphid Toxicity Determination experiment discovery, the virulence of Diacloden is higher than carbosulfan, co-toxicity coefficient is all greater than 120 when Diacloden and carbosulfan proportioning are 1: 1,1: 5,1: 10,1: 15,1: 20, show obvious synergistic effect, Diacloden thus: carbosulfan all had synergistic function between 1: 1 to 1: 20, especially when Diacloden: during carbosulfan=1: 10, co-toxicity coefficient is maximum, and synergistic effect is the most obvious.
