Abstract
The invention discloses an insecticidal composition containing spinosad and thiocyclam, the composition contains the spinosad and the thiocyclam, and the weight ratio of the spinosad to the thiocyclam is (50:1)-(1:80). The composition disclosed by the invention can be used for controlling a variety of insect pests, has obvious synergy, can expand the insecticidal spectrum and has higher activity against asparagus caterpillar, diamond back moth, thrips, paddy borer, rice leaf roller, striped rice borer, paddy thrips, leafhopper, rice gall midge, plant hopper, peach aphid, apple aphid, European red mite, pear leaf worm and citrus leaf-miner; and furthermore, the composition can reduce the dosage of pesticide, reduce the residual quantity of the pesticide on crops and reduce environmental pollution, and is safe to people and animals, good in environmental compatibility and less prone to causing drug resistance of the pests.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination containing multiple killing teichomycin and thiocyclam.
Background technology
Multiple killing teichomycin (spinosad), have insect and tag fast and stomach poison function, have stronger osmosis to blade, can kill subepidermal insect, the longevity of residure is longer, has certain ovicidal action to some insects.Without systemic action.Can effectively preventing Lepidoptera, diptera and Thysanoptera, also well can prevent and treat in coleoptera and orthoptera that some takes food the pest species of blade in a large number, poor to the control efficiency of sucking pest and mite class.Safer to predatory natural enemy insect, because insecticidal action mechanism is unique, not yet find to there is mutual drug-fast report with other insecticides at present.To plant safety without poisoning.Be suitable for vegetables, fruit tree, gardening, crops use.Insecticidal effect affects less by raining.
Thiocyclam (thiocyclam-hydrogenoxalate), molecular formula: C
7h
13nO
4s
3, structural formula: N, N-dimethyl 1,2,3-trithian-5-amido oxalate, is sandworm toxin insecticide, has and tag and stomach poison function also have certain interior suction and fumigation action, and can ovicidal.Slower to the toxic effect of insect, poisoning the lighter can be brought back to life sometimes.It disappears comparatively fast in plant corpus, and the longevity of residure is shorter, and residual quantity during results in crop is little.Thiocyclam is effective to Lepidoptera, coleoptera, homoptera pest, can be used for preventing and treating the various pests on paddy rice, corn, beet, fruit tree, vegetables, but large to the toxicity of silkworm.
But in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.
Different cultivars composition carries out composite, is to prevent and treat the very common method of 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 is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Through inventor's research, find by multiple killing teichomycin and thiocyclam composite after can produce good synergistic effect, and about multiple killing teichomycin and the composite relevant report of thiocyclam and apply not yet open.
Summary of the invention

The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, on this basis, then carry out field trial.
Test method: respectively the mother liquor of each for multiple killing teichomycin thiocyclam mixed agent is diluted to five series concentration during test, is placed in beaker respectively for subsequent use.Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination 3 instar larvae, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 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 contrast lethality is greater than 10%, be then considered as invalid test.Computing formula is as follows:
Insect 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, and calculate the value of often kind of medicament thus with method of least squares.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (take multiple killing teichomycin as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=multiple killing teichomycin of M
multiple killing teichomycintI × the P of+thiocyclam
thiocyclam
In formula: M is the mixture of different ratio
P
thiocyclamfor the ratio that thiocyclam is shared in the composition
P
multiple killing teichomycinfor the ratio that multiple killing teichomycin is shared in the composition
A is selected from multiple killing teichomycin;
B is selected from thiocyclam.
Application Example two:
For examination insect: wild cabbage diamond-back moth.
Test medicine provides by Shaanxi Meibang Pesticide Co., Ltd..
Experimental scheme: through effective lethal concentration scope of preliminary experiment determination multiple killing teichomycin, thiocyclam and the two different ratio mixture.
