Abstract
The purpose of the present invention, a kind of bakanae disease of rice microbicide compositions are provided, by being made according to the following component of volume percent: 1% bleeding agent aqueous solution 50-70%, 99% bronopol 5-25%, 14% isothiazolinone 5-45%, bronopol of the present invention is compounded with isothiazolinone, it is measured by co-toxicity coefficient method, the two compounding has synergistic effect, can be mutually improved, better than single dose, hence it is evident that improve bactericidal and bacteriostatic effect.It with interior suction and double effects of tagging, is not easy to produce resistance with Prochloraz, Tebuconazole, 2-cyano-3-amino-3-phenylancryic acetate ratio, is free of organic solvent, it is environmentally friendly, wide using concentration range while high to seeds secure.
Description
Technical field
The present invention is a kind of bakanae disease of rice microbicide compositions and preparation method.
Background technique
Bakanae disease of rice is common a kind of disease during Rice Production.Foolish seedling disease belongs to Deuteromycotina fungi originally,
It is seed-borne disease mainly by the sick seed dispersal carried disease germs.Bakanae disease of rice conventional sterilization agent medication, Prochloraz, Tebuconazole, cyanogen alkene
The single doses such as bacterium ester, bacterial strain increase dosage and had not only increased cost but also be easy to produce phytotoxicity, inhibit rice seed germination to generate resistance
Rate, preventive effect are substantially reduced.Bakanae disease of rice disease incidence aggravates year by year, has serious influence to yield and quality of rice.
Therefore, the present invention provides that a kind of pair of foolish seedling disease opportunistic pathogen killing power be strong, at low cost, noresidue, environmental-friendly agriculture
Drug composition, and rice paddy seed is impregnated by this combined bactericide, to control and reduce the generation of bakanae disease of rice.
Summary of the invention
It is an object of the invention to overcome the technical deficiency of above-mentioned conventional sterilization agent single dose, a kind of pair of bakanae disease cause of disease is provided
Bacterium killing power is strong, at low cost, noresidue, environmental-friendly composition pesticide, and by this combined bactericide to rice paddy seed
It impregnates, to control and reduce the generation of bakanae disease of rice.
According to an aspect of the invention, there is provided a kind of bakanae disease of rice microbicide compositions, by according to volume basis
The following component of number meter is made:
1% bleeding agent aqueous solution 50-70%,
99% bronopol 5-25%,
14% isothiazolinone 5-45%, in which: the ratio between MIT and CMIT are 1:1-10:1.
Further, the isothiazolinone precentagewise 14% is counted, and the ratio between MIT and CMIT are 11:3.
Further, the bleeding agent preferred embodiment is fatty alcohol polyoxyethylene ether, abbreviation JFC.
Further, bakanae disease of rice microbicide compositions according to the present invention, the following component of the volume percent
It is made: 1% bleeding agent aqueous solution 50%, 99% bronopol 5%, 14% isothiazolinone 5%, in which: the ratio between MIT and CMIT are 1:1.
