Abstract

The fungicide for preventing and curing black spot of fruit tree mainly contains (wt%) 2-80% of ethyl allicin and 0.0002-30% of emulsifiable solution or powder preparation of other fungicides. After compounded, said invention possesses obvious preventing and curing effect, up to above 90%, and can obtain obvious synnergistic effect. Besides, said invention also can be used for preventing and curing several diseases of crops, such as cotton wilt, rhizoctonia disease, grey mould of vegetables, banded sclerotial blight of rice plant and cercospora black spot of peanut, etc..

Description

Farm chemical for preventing and controlling black spot of fruit tree

The present invention relates to a kind of agricultural chemicals, relate in particular to a kind of farm chemical for preventing and controlling black spot of fruit tree such as apple pears.

Black spot of fruit tree is the important disease in the production of fruit trees, and this disease is difficult to treatment in case take place, at this kind disease, though many kinds of bactericide agricultural chemicals have appearred on the agricultural chemicals market,, comprehensive each side reason, all not really desirable in promoting the use of.As " mancozeb ", can only play inhibitory action to the top layer germ, then can't suppress for the germ in the intrusive body; As " thiophanate methyl ", interior absorption is good, controls at fat and works certain effect of being on the black spot of fruit tree, but because of using separately continuously, cause resistance to strengthen, and drug effect descends, and does not have the purpose of control black spot of fruit tree; As " fluorine azoles ", excellent to the black spot of fruit tree preventive effect, but because of it costs an arm and a leg, vast farmers is difficult to accept, and promotes very difficult.

The purpose of this invention is to provide a kind ofly to by fungus-caused effective to preventing and controlling black spot of fruit tree, be difficult for producing resistance, use cost is low, has the farm chemical for preventing and controlling black spot of fruit tree of protection and treatment double action.

Technical scheme of the present invention realizes in the following manner:

Farm chemical for preventing and controlling black spot of fruit tree, it mainly is missible oil or the pulvis that contains S-Ethyl ethylthio sulfonate, other agricultural chemicals, weight percentage is S-Ethyl ethylthio sulfonate 2-80%, other agricultural chemicals 0.0002-30%.

Other agricultural chemicals is nitrile bacterium azoles, Prochloraz, alkene azoles alcohol, brassin lactones, paclobutrazol, gibberellin.

Missible oil formulation solvent is toluene, dimethylbenzene.

Good effect of the present invention is:

1, composite back synergistic effect is remarkable, and control efficiency improves.

2, to the preventing and controlling black spot of fruit tree effect up to more than 90%, obviously be better than producing common fungicide.

3, composite back is difficult for producing resistance, and the lasting period is long.

4, use cost is lower.

5, consumption is little, and quick-acting is good.

Farm chemical for preventing and controlling black spot of fruit tree of the present invention except that black spot of fruit tree is had the control efficiency, can also be prevented and treated cotton wilt, damping off: eliminating vegetable botrytis; Rice sheath blight disease; Multiple diseases on the various crop such as the cercospora brown spot of peanut.

The invention will be further described below in conjunction with implementing prescription:

Prescription 1: S-Ethyl ethylthio sulfonate 20%, nitrile bacterium azoles 3%, emulsifier 11%, surplus is a dimethylbenzene.

Prescription 2: S-Ethyl ethylthio sulfonate 5%, nitrile bacterium azoles 5% after two components are mixed, mixes with solid carrier, pulverizing.

Prescription 3: S-Ethyl ethylthio sulfonate 10%, Prochloraz 10%, emulsifier 8%, surplus is a toluene.

Prescription 4: S-Ethyl ethylthio sulfonate 5%, Prochloraz 5% after two components are mixed, mixes with solid carrier, pulverizing.

Prescription 5: S-Ethyl ethylthio sulfonate 20%, alkene azoles alcohol 3%, emulsifier 10%, surplus is a dimethylbenzene.

Prescription 6: S-Ethyl ethylthio sulfonate 5%, alkene azoles alcohol 5% after two components are mixed, mixes with solid carrier, pulverizing.

Prescription 7: S-Ethyl ethylthio sulfonate 15%, brassin lactones 0.0015, emulsifier 7%, surplus are dimethylbenzene.

Prescription 8: S-Ethyl ethylthio sulfonate 10%, paclobutrazol 5%, emulsifier 10%, surplus are dimethylbenzene.

Prescription 9: S-Ethyl ethylthio sulfonate 10%, gibberellin 0.5%, emulsifier 11%, surplus are dimethylbenzene.
