Abstract
A novel fungicidal composition for agricultural is provided by combining two compounds, 4, 5, 6, 7 -tetrachloro -2 -benzo (c) fthalide and 1 -{N -propyl -N - [2- (2, 4, 6) -trichlorophenox) ethyl] carbamoyl} imidazole (prochloraz).
Description
The present invention relates to be used for the microbicide compositions of agricultural.
Common first names is 1-{N-propyl group-N-[2-(2,4, the 6-Trichlorophenoxy) ethyl of prochloraz] carbamoyl } imidazoles and common first names be 4,5,6 of fthalide, 7-tetrachloro-2-benzo [c] furanone is used for agricultural purposes respectively as mildewcide.
Fthalide has been used to suppress rice blast, and good especially prevention effect and very safe to mammal and fish and shellfish is arranged.Yet its application is limited for preventative bactericide.For example, in case rice plants is infected by Pyricularia oryzae, fthalide is invalid for its treatment.
On the other hand, prochloraz uses as rice seed disinfectant, but is not used for directly handling rice class plant as yet.
Now be surprised to find, by this compound directly being imposed on the rice plants in greenhouse and field, it shows significant prevention and therapeutic action to rice blast.
We are surprised to find, unite with prochloraz and use fthalide to show significant synergy.
Microbicide compositions of the present invention shows good especially inhibition for Pyricularia oryzae especially, show a kind of can not be by the synergy of its single composition expection.Composition not only shows prevention effect, and shows the excellent treatment effect, and the result compares the necessary consumption that has reduced these two kinds of compounds with a kind of composition of independent usefulness.The Fungicidai mixtures that is used for agricultural according to the present invention is effective to pinta (such as brown spot) and the fusarium disease of controlling rice especially.
The ratio of prochloraz and fthalide can alter a great deal, but is 4: 1 to 1: 4 weight ratios in scope generally, and preferred 2: 1 to 1: 2, particularly 1.3: 1 to 1: 1.6.
The fungicide mixture that is used for agricultural according to the present invention can provide with many formulations; such as pulvis, granule, powder-granule mixture, wettable pulvis, suspension concentrate, milkiness concentrate (EC) but liquid and analog prepare these formulations by known method.As the assistant agent that is used to prepare these formulations, for example solid carrier such as diatomite, white lime, calcium carbonate, talcum, white carbon, kaolin, bentonite and zeolite can have been pointed out; Solvent based such as toluene, dimethylbenzene, naphtha, ethanol, dioxanes, acetone, isophorone, methyl iso-butyl ketone (MIBK), dimethyl formamide, dimethyl sulfoxide (DMSO) and N-N-methyl-2-2-pyrrolidone N-; The surfactant that use wetting agent class such as sodium alkyl sulfate, sodium alkyl benzene sulfonate, sodium lignin sulfonate, polyoxyethylene glycol alkyl ether, polyoxyethylene lauryl ether, polyoxyethylene alkylaryl ether, polyoxyethylene sorbitan fatty acid ester and multiple other this area.
The microbicide compositions that is used for agricultural according to the present invention shows mammal and the very high safety of fish, and proof is few or do not have a phytotoxicity to useful crop especially rice.
The bactericidal composition that is used for agricultural can be united use with other bactericide and Insecticides (tech) ﹠ Herbicides (tech) and plant growth regulator.
The two kinds of 1.0-95.0% that reactive compound is a gross weight containing usually of fungicide preparation that are used for agricultural of the present invention preferably use the reactive compound of 3.0-70%.The application dosage of bactericide is generally the reactive compound of per hectare 150-600g, preferred 250-400g combination.
The following example is used to describe in detail the preparation that is used for the microbicide compositions of agricultural according to of the present invention.Prescription 1 (immobilising pulvis)
Obtain pulvis by the prochloraz of even mixing 1.5 weight portions, the fthalide of 1.5 weight portions, the white carbon of 1.0 weight portions, the aggregating agent prepared therefrom of 0.5 weight portion and the clay of 95.5 weight portions.Prescription 2 (wetting powders)
Obtain wetting powder by the prochloraz of even mixing 15.0 weight portions, the fthalide of 15.0 weight portions, the sodium lignin sulfonate of 5.0 weight portions, the white carbon of 15.0 weight portions and the kaolin of 50.0 weight portions.Prescription 3 (granules)
Make granule by the prochloraz of even mixing 1.5 weight portions, the fthalide of 1.5 weight portions, the bentonite of 30.0 weight portions and the clay of 67.0 weight portions by conventional process.
Mixture of the present invention proves in following experimental example the bactericidal activity of Pyricularia oryzae (rice blast).Embodiment 1 control Pyricularia oryzae
The rice plants of the 3-4 leaf phase of incubation growth in the soil in the plastic basin of diameter 9cm (" Nihonbare " plants) is used for test, with test of proof prevention effect and therapeutic action.
Can buy prescription by its commodity and use active component; Fthalide is 20% wettable powder, and prochloraz is 25%EC, all is diluted to predetermined concentration.The preparation of dilution is sprayed onto on the plant by the amount of per 3 basins with 30ml.
Plant is used spore suspension 5-6 * 10 of the Pyricularia oryzae that obtains from the rice plants that is infected by rice blast in advance
6/ ml sprays inoculation.
In prophylactic tria, plant inoculate after 1 day at sample spray medicine, indoorly places 24 hours down at 25 ± 2 ℃ wet then, is placed on the influence of wait eqpidemic disease in the greenhouse again.
In therapeutic test, sample is being sprayed medicine by the mould inoculation after 24 hours.Then plant is placed on the influence of waiting for eqpidemic disease in the greenhouse.
Gradient of infection determines that to the evaluation of the damage of plant protective capacities can be calculated according to following formula by inoculating after 7 days:

Seed rice (kind " Nihonbare ") by drilling in the rice seedling bed that does not flood, in order to accelerate and to promote consistent eqpidemic disease outburst, to be cut into the long fragment of about 1cm by the blade that Pyricularia oryzae infects, spread to the whole test field as inoculation source.Consequently the rice plants in the experimental field is placed under the state that is subjected to the rice blast infection.
Twice come dispenser with the consumption of each plot 100ml with small-sized day with fog sprinkling according to the prescription of the technology of embodiment 1 preparation test and with predetermined concentration.
Eqpidemic disease occurs on 2 leaves or 3 leaves, sprays in the 3-4 leaf phase for the first time to carry out, and sprays after 7 days for the second time.
Check to eqpidemic disease outburst is carried out 3 times, promptly spray for the first time after 7 days be right after spray for the second time before (the 1st time), spray 2 days for the second time after (the 2nd time) and spray 8 days for the second time after (the 3rd time), to estimate the inhibition effect of filling a prescription.
Degree of injury for rice blast is represented with %, estimates on each processed sample.The prevention ability (%) of each prescription is calculated according to the formula of embodiment 1.Test results test sample compound concentration protective capacities
