Abstract
The invention relates to a bactericide composition for control of corynespora cassiicola, with synergism, of crops. The composition is composed of two or three active substances, wherein A component is diethofencarb, and B and C components are any one of azoxystrobin, pyrimethanil, prochloraz, hexaconazole, cyprodinil, fluazinam, boscalid, fludioxonil, mancozeb and chlorothalonil. In a binary composition AB, the weight ratio of diethofencarb to another bactericide is 99-1:1-99. In a ternary composition ABC, the weight ratio of A, B and C is 1-50:1-50:1-50. The other components are auxiliary components which are allowed to be used and acceptable in pesticides. The bactericide composition can be prepared into wettable powder, missible oil, suspending agents, water dispersible granules, emulsion in water and microemulsion. The bactericide composition has obvious synergism, has multiple action mechanisms and acting sites and can delay the occurrence of resistance to drugs of pathogens.
Description
Technical field
The present invention relates to pesticide field, be specifically related to a kind of microbicide compositions for control crop rod spore leaf spot.
Background technology
Many main excellent spores (Corynespora cassiicola) are a kind of important plant pathogenic fungis, can parasitize vegetables, trees and the gardening ornamental crops of the torrid zone and subtropical zone.2005 so far, in the field investigation to China's vegetables rod spore leaf spot harm, find that 19 provinces such as Shandong, Hebei, Beijing, Liaoning, Jilin, Henan, Yunnan and Hainan should disease seriously break out, vegetables and the economic crops rubber such as main harm cucumber, eggplant, tomato, Kidney bean, the annual area 10 million mu that occurs, loss surpasses 5,000,000,000.Many main excellent spores have the host extensively, infect that destructive power is strong, the route of transmission extensively, characteristics such as variation, prophylactico-therapeutic measures shortage very easily, thereby excellent spore leaf spot rises to universally acknowledged Major Diseases by Minor diseases, becomes the critical limitation factor that determines the main host plants industry development.Chemical control plays vital effect as the important means of integrated control for the control of crop rod spore leaf spot, but the present domestic chemical control medicament that there is no registration.
The mould prestige of second belongs to carbamate fungicide, has interior suction therapeutic action, acts on the fungi tubulin, and Antifungi mitosis is easily developed immunity to drugs.
Fluoxastrobin belongs to methoxy acrylic bactericide, and fungicidal spectrum is wide, and oomycetes, sac fungi, imperfect fungus and basidiomycetes are all had good preventive effect, its by with the germ body in the Q of cytochrome b (cytb) among the mitochondria Complex II I
0The site in conjunction with and the Antifungi respiration easily develops immunity to drugs.
Phonetic mould amine belongs to the anilino-pyrimidine series bactericidal agent, and mechanism of action is the secretion of Antifungi protein, reduce some hydrolase level, and these hydrolases causes that with pathogen the host tissue necrosis is relevant, have to root out and therapeutic action, easily develop immunity to drugs.
Prochloraz belongs to the imidazoles bactericide, and fungicidal spectrum is wide, has conductivity in plant corpus, works by the ergosterol biosynthesis of Antifungi cell function, easily develops immunity to drugs.
Own azoles alcohol belongs to triazole bactericidal agent, by suppressing the biosynthesis of thalline ergosterol somatic cells film function is damaged, thereby the formation that suppresses or disturb thalline to adhere to growth, mycelia and the spore of spore and haustorium, easily develops immunity to drugs.
Cyprodinil belongs to the aminopyrimidine bactericide, by the biosynthesis of inhibition methionine and the biologically active of hydrolase, causes germ dead.
Fluazinam is the Mitochondria uncoupler.Suppress the course of infection in all stages by suppressing spore germination, mycelial growth and sporulation, fungicidal spectrum is very wide, and its effect is better than the GPF (General Protection False bactericide.
Boscalid belongs to the Novel tobacco acid amide fungicides, by suppressing mitochondrial succinate dehydrogenase, hinders tricarbonic acid cycle, the division of interference cell and growth.Fungicidal spectrum is wide, has protection and therapeutic action.
Fludioxonil belongs to the new pyrrole series bactericidal agent, by the relevant transferase of inhibition thalline glucose phosphorylated, and the Antifungi mycelial growth, cause germ dead.
Mancozeb belongs to dithiocarbamate fungicide; be mainly sulfydryl (SH) combination in the oxidation that suppresses pyruvic acid in the thalline and the dithio-octanoic acid dehydrase that participates in the pyruvate oxidation process; its fungicidal spectrum is wide, has protective effect, but does not have interior suction therapeutic action.
Tpn belongs to substituted beneze-group fungicides, can with the fungal cell in glyceraldehyde 3-phosphate dehydro-genase have an effect, with the protein combination that contains cysteine in this enzyme body, destroy enzyme activity, fungal cell's metabolism is damaged and loss of life power.Its fungicidal spectrum is wide, but only has protective effect, does not have interior suction therapeutic action.
Flyash is common combustion residue, is rich in simultaneously macroelement and Trace Elements, but does not obtain utilizing always.In view of above problem, the present invention is studied nanometer additive, has made nanometer materials, has both had adsorptivity, dispersiveness, rheological characteristic, porous and surface acidity, has again the skin effect of nano material, dynamics model occurs.Be conducive to the sorption and desorption to nitrogen, phosphorus, potassium and organic carbon, improve the benefit of using of agricultural chemicals, build good ecotope, also development and the improvement soil for the friendly type agricultural chemicals of efficient context provides scientific basis.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of safe and effective to cucumber rod spore leaf spot, delays and stop the microbicide compositions of development of drug resistance.In order to solve the problems of the technologies described above, the invention provides a kind of microbicide compositions.In the microbicide compositions, binary composition is comprised of in the mould prestige of second and Fluoxastrobin, phonetic mould amine, Prochloraz, own azoles alcohol, cyprodinil, fluazinam, Boscalid, fludioxonil, mancozeb and the tpn any one, in the ternary composition, by in the mould prestige of second and Fluoxastrobin, phonetic mould amine, Prochloraz, own azoles alcohol, cyprodinil, fluazinam, Boscalid, fludioxonil, mancozeb and the tpn any two kinds form.Among the binary composition AB, the proportioning of the mould prestige of second and another bactericide is by weight being 99-1: 1-99, and among the ternary composition ABC, A, B and C proportioning are 1-50: 1-50: 1-50 by weight.
Except the mould prestige of second and other active components, comprise also in the microbicide compositions of the present invention that the auxiliary agent such as solvent, dispersant, emulsifier, stabilizing agent, antifreezing agent and wetting agent and other are of value to the known substance of active ingredient stable and performance drug effect in preparation, these compositions all are commonly used in the pesticidal preparations or allow to use, be not particularly limited, determined concrete composition and consumption for control crop rod spore leaf spot especially.Described filler is nano flyash, and the nano flyash preparation method is: the flyash mixed solution at 0 ℃ of lower stir-activating 5h, is added lauryl sodium sulfate, 5 * 10
4R/min high speed shear 6h, reaction solution are cooled to decompress filter after the room temperature, and gained is deposited under 105 ℃ and is dried to constant weight, obtains nano flyash.
Product described in the invention (composition) can the finished product preparation form provide, and namely each material mixes in the composition, and the composition of composition also can the single dose form provide, and directly directly mixes in bucket or tank before the use, then is diluted to required concentration.
