Description
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially a kind of composition and the application that contain fennel artemisin.
Background technology
macro tetrolide
Be the antibiotic with macrolide structure produced by the mutation of streptomyces griseus Liuyang, for low toxicity, low-residual, can prevent and treat the broad spectrum acaricides of the multiple mite class of various crop, control efficiency is good.Have good action of contace poison to the tetranychid of various crop, without interior absorption, medicament has lipophilicity, if having efficiently one-tenth mite, does not kill and wound Predatory Mites, and evil mite not easily produces resistance, kills mite spectrum comparatively extensively, all effective to tetranychid, goitre mite.With some organic phosphors or carbamate pesticide composite, have significant synergistic effect.To the action of contace poison of evil mite, 7 ~ 14 days lasting periods.
Physicochemical property: the mixture be made up of 5 components, four viable bacteria elements are main active component.Sterling is colourless prism-shaped crystallization, fusing point 112 DEG C ~ 113 DEG C.Be soluble in benzene, ethyl acetate, chloroform, ether, acetone, dissolve in 50% solvent such as ethanol, n-hexane, water insoluble.To ultraviolet-sensitive, in the sun irradiate 2 days, decomposable asymmetric choice net 50% with property through skin LDso >2 000mg/kg.Proterties sterling is colourless prism-shaped crystallization.
fennel artemisin
Fennel punt-pole element is the vegetable insecticide extracted for raw material with fennel punt-pole.Main component is santonin and stemonine.Nontoxic to person poultry safety, insect tool is tagged and stomach poison function.Commercial preparation is low toxic pesticide, and the Mouse oral lethal dose of 50 (LD50) is 15000-19256.7 mg/kg.Without chronic toxicity.
At present, also do not report about containing the composite of fennel artemisin.
Summary of the invention
The object of the present invention is to provide a kind ofly has Pesticidal combination containing fennel artemisin and application thereof, said composition active ingredient is macro tetrolide and fennel artemisin, weight ratio wherein containing fennel artemisin is, macro tetrolide: fennel artemisin=1-15:1, farthest alleviate the problem of current pest resistance to insecticide, thus decrease the consumption of agricultural chemicals, also alleviate the impact for environment.
Technical scheme of the present invention is:
A composition containing fennel artemisin, active ingredient is macro tetrolide and fennel artemisin, and the weight ratio wherein containing fennel artemisin is, macro tetrolide: fennel artemisin=1-15:1.

Composition containing fennel artemisin of the present invention, for preventing and treating the aphid of crop, heart-eating worm, cabbage caterpillar, diamond-back moth, vegetable aphid, is particularly useful for anti-eliminating aphis.
The beneficial effect of the invention is:
Said composition is complex insecticidal composition, significantly enhances insecticidal effect, delays the generation of pest resistance to insecticide, and expands effective active control spectrum, and have speed fast, the lasting period is long, and consumption is low, eco-friendly feature.Weight ratio containing fennel artemisin is, macro tetrolide: fennel artemisin=1-15:1, serves good synergistic function by composite, has effectively resisted the problem that pest resistance produces, and reduces the consumption of agricultural chemicals.This complex composition is particularly useful for anti-eliminating aphis, and has good effect to it.
Study the compound synergic of composition of the present invention, test adopts aphid.
Toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament is calculated according to the abundant method of Sun Yun.
Table 1 different ratio relation is to the toxicity test result of aphid
| Process | Co-toxicity coefficient |
| Macro tetrolide 1: fennel artemisin 1 | 184.2 |
| Macro tetrolide 5: fennel artemisin 1 | 301.8 |
| Macro tetrolide 8: fennel artemisin 1 | 324.1 |
| Macro tetrolide 10: fennel artemisin 1 | 312.4 |
| Macro tetrolide 15: fennel artemisin 1 | 169.3 |
| Macro tetrolide | |
| Fennel artemisin |
As can be seen from Table 1, composite containing fennel artemisin, co-toxicity coefficient is far longer than 120, has very high synergistic effect, especially macro tetrolide: during fennel artemisin=5-10:1, synergistic effect is more obvious.
