Description
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially composition and the application of a kind of macro tetrolide and nimbin.
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.
nimbin
Print chinaberry (lian) is the title of a kind of fast-growing deciduous tree, and seed and bark all can be used as medicine.Print chinaberry is the desirable pesticide plant of generally acknowledging in the world for 2013.Print chinaberry (Azadirachta indica A.Juss) is Meliaceae Melia arbor, extensively plants in tropical and subtropical region.Originally analysis is investigated to a plague of locusts, in the print seed of chinaberry, leaf and bark, containing a kind of material---nimbin, just because of its existence, the magical function making print chinaberry have worm to cure the disease.Show through modern study, the compositions such as the nimbin extracted from print chinaberry fruit are wide spectrums recognized in the world, efficient, low toxicity, easily degraded, noresidue insecticide and there is no pesticide resistance, to nearly all plant insect, indoor bedbug, flea, fly, mosquito etc. all have repelling and killing efficacy, and to people and animals and surrounding environment without any pollution, print chinaberry simultaneously and also there is medical function to numerous disease, will have in medicine and apply widely.
At present, also do not report about macro tetrolide and the composite of nimbin.
Summary of the invention
The object of the present invention is to provide a kind of Pesticidal combination and the application thereof that have macro tetrolide and nimbin, said composition active ingredient is macro tetrolide and nimbin, wherein the weight ratio of macro tetrolide and nimbin is, macro tetrolide: nimbin=1:1-15, 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 for macro tetrolide and nimbin, active ingredient is macro tetrolide and nimbin, and wherein the weight ratio of macro tetrolide and nimbin is, macro tetrolide: nimbin=1:1-15.

The composition of macro tetrolide of the present invention and nimbin, for preventing and treating the aleyrodid of crop, aphid, unguiculus mite, leafhopper, goitre mite, is particularly useful for preventing and treating leafhopper.
Beneficial effect of the present 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.The weight ratio of macro tetrolide and nimbin is, macro tetrolide: nimbin=1:1-15 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 preventing and treating leafhopper, has good effect to it.
Study the compound synergic of composition of the present invention, test adopts leafhopper.
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 leafhopper
| Process | Co-toxicity coefficient |
| Macro tetrolide 1: nimbin 1 | 225.9 |
| Macro tetrolide 1: nimbin 5 | 627.1 |
| Macro tetrolide 1: nimbin 8 | 704.5 |
| Macro tetrolide 1: nimbin 10 | 610.2 |
