Abstract
A kind of bactericidal composition containing triazolone and southerm yew leaf extract, belongs to bactericide technical field.It contains active ingredient triazolone and southerm yew leaf extract, and the weight ratio of triazolone and the southerm yew leaf extract is 1:10~10:1, described southerm yew leaf extract is obtained by following steps：By leaves of Taxus mairei crushed after being dried into coarse powder, the EtOH Sonicate for adding 6 10 times of southerm yew leaf coarse powder weight extracts 23 times, 30 50 minutes every time, filter, filter residue is discarded, after merging extract solution, obtained extract solution carries out flash concentration to the 1/10 1/14 of original volume under the conditions of 60 70 DEG C using Reduced Pressure Concentration Device, concentrate is spray-dried or be dried in vacuo into dry powder, is obtained.The present invention has notable preventive effect by southerm yew leaf extract and triazolone compounding to rice green smut and rice ear rot, can reach more than 90%.
Description
Technical field
The invention belongs to bactericide technical field, and in particular to a kind of killing containing triazolone and southerm yew leaf extract
Bacteria composition.
Background technology
The preventing and treating of crop disease accounts for very big proportion in agriculture production cost, as the development bulk sterilization agent of science and technology is continuous
Emerge in large numbers, and drug effect more and more higher.In actual use, many bactericide selectivitys are strong, and target scope is narrower, it is difficult to meet anti-
The requirement controlled is, it is necessary to which various medicaments are used in mixed way.However, combined use of pesticides technology content is higher, peasant oneself is mixed often
Produce drug effect decline, poisoning produces.Therefore, it is necessary to which the good bactericide of compounding effect is made into built agent, reach simple, high
Imitate the purpose of controlling disease.
Triazolone（Triadimefon）, also known as triadimefon, its chemical name are 1 one（4 monochloro-benzene epoxides）One 3,3 one two
Methyl 1 (1H-1,2,4 one triazole-l- bases)-α-butanone, is the first wide variety of triazole bactericidal agent.The bactericide
With efficient, less toxic, low-residual, the lasting period is long, absorbability is strong the advantages of, while there is prevention, treat, root out, fumigation action.
Its mechanism of action is mainly to suppress the synthesis of germ ergosterol, so as to suppress mycelial growth and sporogenesis.Its mechanism of action
Determine that it is good to fungus disease effect, but to bacterium class disease effect extreme difference.
The content of the invention
The problem of existing for prior art, it is an object of the invention to design offer one kind to contain triazolone and southern red bean
The technical scheme of the bactericidal composition of China fir leaf extract.
Described a kind of bactericidal composition containing triazolone and southerm yew leaf extract, it is characterised in that containing effective
Composition triazolone and southerm yew leaf extract, the weight ratio of triazolone and the southerm yew leaf extract is 1:10~
10:1, described southerm yew leaf extract is obtained by following steps：By leaves of Taxus mairei crushed after being dried into coarse powder,
The EtOH Sonicate for adding 6-10 times of southerm yew leaf coarse powder weight extracts 2-3 times, each 30-50 minutes, filters, discards filter
Slag, after merging extract solution, obtained extract solution carries out flash concentration extremely under the conditions of 60-70 DEG C using Reduced Pressure Concentration Device
The 1/10-1/14 of original volume, concentrate is spray-dried or be dried in vacuo into dry powder, leaves of Taxus mairei is obtained and carries
Take thing.
A kind of described bactericidal composition containing triazolone and southerm yew leaf extract, it is characterised in that the triazole
The weight of ketone and southerm yew leaf extract ratio is 1:9~9:1.
A kind of described bactericidal composition containing triazolone and southerm yew leaf extract, it is characterised in that the triazole
The weight of ketone and southerm yew leaf extract ratio is 1:7~7:1.
A kind of described bactericidal composition containing triazolone and southerm yew leaf extract, it is characterised in that the triazole
The weight of ketone and southerm yew leaf extract ratio is 1:4~4:1.
A kind of described bactericidal composition containing triazolone and southerm yew leaf extract, it is characterised in that the triazole
The weight of ketone and southerm yew leaf extract ratio is 2:3~3:2.
A kind of above-mentioned bactericidal composition containing triazolone and southerm yew leaf extract, is carried by leaves of Taxus mairei
Take thing and triazolone compounding that there is notable preventive effect to rice green smut and rice ear rot, can reach more than 90%.
Embodiment
The present invention is further illustrated below in conjunction with test example.
