In the technique scheme, the best proportioning of its component is bacillus thuringiensis,Bt 3000～6000PxIU/ milligram, Celastrus angulatus 1.0～2.0%, emulsifier 8.0～10.0%, moistening spreader-sticker 2.5～4.0%, preservative 1.0～2.0%, synergist 1.5～3.0%, uv-protection agent 1.0～3.0%, pH value conditioning agent 0.1～3.0%, antifreezing agent 5.0～8.0%, and surplus is a water.Emulsifier component is with 0201 and peaceful newborn 34
#Composition be best.Moistening spreader-sticker component is the best with the composition of anhydrous sorbitol polyoxyethylene ether fatty ester and lauryl sodium sulfate.Preservative component is the best with the composition of methyl hydroxybenzoate and Kai Song.Boosting components is with potash, the composition of edetate disodium, oleic acid and honey element is the best.Uv-protection agent component is best with the sodium lignin sulfonate.PH value conditioning agent component is best with the citric acid.The antifreezing agent component is best with ethylene glycol.
Bacillus thuringiensis,Bt (Bacillus thuringiensis) is a kind of bacillary insecticide, (after insect eats medicament, in midgut, makes enteron aisle anesthesia, stops to get food because its unique insecticidal mechanism; And destroy the enteron aisle inner membrance, and the bacillus gemma is sprouted in intestines, a large amount of breeding, finally make insect hungry and septicemia appears and extremely) and low toxicity, nothing " three cause harm ", to characteristics such as natural enemies securities, be widely used in the control of lepidoptera pest.But the repeated drug taking of its short time easily causes the enhancing of pest resistance to insecticide, has also increased the control cost simultaneously.Celastrus angulatus (celangulin) is a kind of plant insecticide, also is a kind of low toxicity, nothing " three cause harm ", to the biopesticide of natural enemies security, and main insecticidal mechanism is after insect eats medicament, causes polypide anesthesia, food refusal, causes insect hungry and dead.Be mainly used in agricultural insect management.But the result of the test of field control cabbage caterpillar shows, eat this medicament of less dosage when insect after, after polypide anesthesia, food refusal a couple of days, still can revive, continue to harm the crops.Especially to some at advanced age pest controling effect not ideal.
Complex preparation provided by the present invention has effectively overcome the deficiency of the single use of above-mentioned preparation, has following advantage:
1, two kinds of insecticidal active ingredients among the present invention have good synergistic effect, and its co-toxicity coefficient is 260～300.Test shows, after insect eats composite drug, causes polypide anesthesia, food refusal; Bacillus thuringiensis,Bt in the enteron aisle is destroyed the enteron aisle inner membrance simultaneously, makes insect dead in the anesthesia process.Even if insect eats the medicament of less dosage, polypide soon also can be dead under dual efficacy of a drug effect.Effectively overcome the relatively poor deficiency of the single result of use of Celastrus angulatus.
2, the present invention is the compound formulation of bacillus thuringiensis,Bt and Celastrus angulatus, and its efficient, low toxicity had both kept the biopesticide characteristic, had widened the scope of application of single medicament again, had improved drug effect, and was particularly particularly remarkable to vegetable-crop pest-insect diamond-back moth control efficiency.(consumption of key component is: bacillus thuringiensis,Bt 2000PxIU/ milligram+20 micrograms Celastrus angulatus/milligram suspension emulsion) dilution is 1000 times for compound formulation of the present invention, control efficiency to diamond-back moth all is stabilized in 85～95%, apparently higher than above-mentioned both unitary agents.Below be the control efficiency of several preparations, see Table 1 diamond-back moth.
