Abstract
The invention discloses a dinotefuran-containing pesticidal composition, which comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from the dinotefuran, the active ingredient B is selected from any one of imidacloprid, acetaniprid, thiamethoxam and thiacloprid, and the weight part ratio of the active ingredient A to the active ingredient B is (1 to 50): (1 to 50). The dinotefuran-containing pesticidal composition has the advantages of preventing various pests, having obvious synergistic effect, expanding the insecticidal spectrum, and having high activity to sucking pests such as aphids, plant hoppers, leafhoppers and aleyrodids and Lepidoptera pests such as plutella xylostella and beet armyworm, reducing the dosage of pesticide, lowering the residual quantity of pesticides in crops, and lightening the environmental pollution. The composition is safe for persons and animals, is excellent in environment compatibility, and is not easy to enable the pests to generate drug resistance.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains MTI-446.
Background technology
MTI-446, English common name (dinotefuran), chemical name 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine.The chemical constitution of itself and existing nicotinic insecticide is far from each other, and chloro-pyridine base, chloro thiazolyl before its tetrahydrofuran base has replaced do not contain the halogen family element.Simultaneously, also different at aspect of performance with nicotine.So people are referred to as " furans nicotine " at present.This medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and has promptly shown very high insecticidal activity at very low dosage.This medicament is fool proof to mammal, birds and aquatile, and crop is not had poisoning, can be used for numerous crops such as paddy rice, fruit tree, vegetables.
Yet in the real process of agricultural production, the problem that pest control is easy to generate most is the generation of pest resistance to insecticide.Important insect such as lepidoptera pest are because its breeding cycle is short, and breeding amount is big, and mobility is little on the agricultural, and selfing degree height is easy to generate resistance especially.
The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find MTI-446 and Imidacloprid, Acetamiprid, thiophene worm quinoline and MTI-446 can produce good synergistic effect after composite, and still unexposed about the composite relevant report of MTI-446 and Imidacloprid, Acetamiprid, thiophene worm piperazine and thiophene worm quinoline.

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 two:
For trying insect: rice hoppers.
Test medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
Experimental scheme: effective lethal concentration scope of determining MTI-446, the former medicine of B and the two different proportioning mixture through preliminary experiment.
Test method: respectively the mother liquor of each mixed agent of MTI-446 effective active composition B is diluted to five series concentration during test, places beaker standby respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the rice 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 examination 3 instar larvaes, 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 rice hoppers 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 the MTI-446 is the standard medicament, and its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=MTI-446 of M
MTI-446TI * P of+effective active composition B
