Description

A kind of composition pesticide and its application
Technical field
The present invention relates to technical field of pesticide, and in particular, to a kind of composition pesticide and its application.
Background technology
In the real process of agricultural production, fungi is most important pathogenic species group, and many important diseases are such as Downy mildew, late blight, balck shank and cotton disease etc. are all by fungus-caused.Plant virus is the pathogen for being only second to fungi. It is to include infectious nucleic acid, drapes over one's shoulders the entity of protein coat outside, it is characterized in that can infect host cell and be caused by infection Defect phenomenon.Many important diseases such as stripe disease, black streaked dwarf virus of rice and virosis etc. are drawn by virus It rises.
Currently, applying pesticides are prevention crop fungi or virus disease the most effective means, but existing pesticide produces Product can only prevent the plant disease of single kind, different types of disease be generally required different agricultures is respectively adopted Drug kind is prevented, and control effect is poor, and the prevention period is long, of high cost, can also cause serious environmental pollution.Therefore, There is an urgent need for develop one kind to be directed to plurality of plant diseases progress integrated control and control effect Pesticidal products outstanding.
Invention content
The object of the present invention is to provide a kind of composition pesticides, efficiently cope with crop disease caused by fungi and/or virus Mixing occur, be effectively improved crop health.
To achieve the goals above, the present invention provides a kind of composition pesticide containing active constituent, the active constituent Including cyazofamid, cymoxanil and lentinan, the weight ratio of the cyazofamid, cymoxanil and lentinan is 1：(0.01-60)： (0.005-46)。
On the other hand, the present invention also provides pesticide combinations as described above makees caused by prevention fungi and/or virus Application in object disease, wherein the crop disease includes crop disease caused by fungi and/or virus.
Through the above technical solutions, the active constituent cyazofamid, cymoxanil and mushroom in the composition pesticide of the present invention are more Sugar is proportionally applied in combination, and can effectively prevent fungi and/or the virus of Cereal, melon fruits and vegetables, tobacco, lawn and flowers Caused crop disease.Relative to being used alone cyazofamid, cymoxanil or lentinan, and with use cyazofamid, cymoxanil It is compared with both the arbitrary compounding in lentinan, composition pesticide of the invention is by cyazofamid, cymoxanil and lentinan three Person is used in compounding, and has more significant control effect, the use ratio of cyazofamid, cymoxanil and lentinan is in wider range Inside there is this synergistic effect, it is possible to reduce dosage reduces cost, mitigates pollution of the pesticide residue to environment.The present invention's Composition pesticide can not only prevent the various crop disease caused by fungi and/or virus simultaneously, and the sterilization for playing wide spectrum is anti- Virus effectiveness, and increase than existing Pesticidal products to the control effect of each independent plant disease.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
Specific implementation mode
The specific implementation mode of the present invention is described in detail below.It should be understood that described herein specific Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The first aspect of the present invention：A kind of composition pesticide is provided, the composition pesticide contains active constituent, the work Property ingredient include cyazofamid, cymoxanil and lentinan, the weight ratio of the cyazofamid, cymoxanil and lentinan can be 1： (0.01-60)：(0.005-46).
Through the above technical solutions, the active constituent cyazofamid, cymoxanil and mushroom in the composition pesticide of the present invention are more Sugar be proportionally applied in combination, can effectively prevent Cereal, melon fruits and vegetables, tobacco, lawn and the fungi of flowers, virus or Crop disease caused by the two mixing.Relative to being used alone cyazofamid, cymoxanil or lentinan, and with use cyanogen white Both arbitrary compounding in azoles, cymoxanil and lentinan is compared, and composition pesticide of the invention is by cyazofamid, cymoxanil and perfume (or spice) Mushroom polysaccharide three is used in compounding, and has a more significant control effect, the use ratio of cyazofamid, cymoxanil and lentinan compared with There is this synergistic effect in wide range, it is possible to reduce dosage reduces cost, mitigates pollution of the pesticide residue to environment. The composition pesticide of the present invention can not only be prevented simultaneously mixes caused various crop disease by fungi, virus or the two, The sterilizing and anti-virus effect of wide spectrum is played, and is had than existing Pesticidal products to the control effect of each independent plant disease It is improved.
In the present invention, cyazofamid is with interior suction, protection, treats and root out active imidazoles series bactericidal agent, English name Referred to as cyazofamid, No. CAS is 120116-88-3, shown in structural formula such as formula (1)：
