Summary of the invention
In order to satisfy the needs of pesticide producing, make full use of two kinds of active components be mixed the synergistic effect that produced, 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 thiophene worm piperazine and carbosulfan.
The object of the present invention is achieved like this: a kind of Pesticidal combination that contains thiophene worm piperazine and carbosulfan, comprise effective active component, auxiliary agent and filler, and the weight hundred of effective active composition thiophene worm piperazine and carbosulfan is than being 1~60: 80~1.
The described Pesticidal combination that contains thiophene worm piperazine and carbosulfan, the percentage by weight of thiophene worm piperazine and carbosulfan are 1~40: 60~5.
The described Pesticidal combination that contains thiophene worm piperazine and carbosulfan, the percentage by weight of thiophene worm piperazine and carbosulfan are 5~15: 40~5.
Described thiophene worm piperazine and the carbosulfan insecticidal composite of containing, the percentage by weight of thiophene worm piperazine and carbosulfan is 5~10: 40~10.
Described thiophene worm piperazine and the carbosulfan insecticidal composite of containing, the optimum activity proportioning of thiophene worm piperazine and carbosulfan is 5: 1~1: 15, preferred proportioning is 1: 1~1: 10.
The described Pesticidal combination that contains thiophene worm piperazine 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 thiophene worm piperazine and carbosulfan is mainly used in and anti-eliminates aphis, scale insect, trialeurodes vaporariorum, rice fulgorid, thrips and striped flea-beetle.
The invention has the advantages that:
(1) thiophene worm piperazine and carbosulfan composite after, different fully 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.Pass through Toxicity Determination earlier, 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, standby 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 thiophene worm piperazine, the former medicine of carbosulfan and the two different proportioning mixture through preliminary experiment, each medicament designs five gradient concentrations respectively by active constituent content and handles, and does contrast with the space management that does not contain former medicine.
Test method: respectively the mother liquor of thiophene worm piperazine, carbosulfan and each mixed agent is diluted to above 5 series concentration during test, places beaker standby respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the fresh cotton floral leaf of the same size that does not contact any medicament soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then, under 25 ℃ of conditions, raise for the examination aphid, every processing repeats for 3 times, every to repeat used examination borer population be 20, establishes blank simultaneously, 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 of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (with thiophene worm piperazine is the standard medicament, and its toxicity index is 100):
TI * the P of the theoretical toxicity index (TTI) of M=thiophene worm piperazine
Thiophene worm piperazineTI * the P of+carbosulfan
Carbosulfan
In the formula: M is the mixture of different proportionings
P
CarbosulfanBe carbosulfan shared ratio in composition
P
Thiophene worm piperazineBe thiophene worm piperazine shared ratio in composition
Result of the test is as shown in table 1:
The different proportionings with carbosulfan of table 1 thiophene worm piperazine are to the toxicity test of cotton aphid
As shown in Table 1, thiophene worm piperazine and carbosulfan and composite product are to cotton aphid Toxicity Determination experiment discovery, the virulence of thiophene worm piperazine is higher than carbosulfan, co-toxicity coefficient is all greater than 120 when thiophene worm piperazine and carbosulfan proportioning are 1: 1,1: 5,1: 10,1: 15,1: 20, show obvious synergistic effect, thiophene worm piperazine thus: carbosulfan all had synergistic function between 1: 1 to 1: 20, especially when thiophene worm piperazine: during carbosulfan=1: 10, co-toxicity coefficient maximum, synergistic effect are the most obvious.
