Description
Technical field
Bactericidal composition of the present invention is using tetramycin, fluorine azoles ring bacterium amine as active ingredient, suitable for preventing rice pears
Crop disease, especially rice blast caused by spore (Pyricularia oryzae Cav.).
Background technology
Tetramycin is by S. ahygroscopicus Wuzhou subspecies (Streptomyces ahygroscopicus
Subsp.Wuzhouensis n.subsp) biological pesticide produced by strain liquid submerged fermentation, by the life for inhibiting mycelia
It is long, the resistance of crop is induced, and promote plant growth and reach prevention purpose, be applicable in a variety of fungies of various forests, bacteriosis
Prevention.
Fluorine azoles ring bacterium amine is a kind of systemic fungicide, and the eupnea process of energy suppression target pathogen has good
Therapeutic and protective effects.
Rice blast is one of big important disease of rice four, by grey pears spore Phyricularia grisea (Cooke)
Sacc. Magnaporthe grisea Pyricularia oryae Cav. belong to Deuteromycotina fungi to disease.
Rice blast hazard rice each section all occurs in rice entire breeding time.Rice shoot becomes yellowish-brown after morbidity
And it is withered, apparent scab is not formed, and when moist, it is mould can to grow cinerous.In China south and north, rice region has different degrees of hair
Raw, popular time general underproduction 10-20%, the serious underproduction reaches 40-50%, falls ill, can make in rice seedling seedling stage and tillering stage
Blade is largely withered, and full field is in shape is burnt when serious, though the strain of some rice is not withered, the young leaves of extraction is not easy to extend, and plant withers
It contracts and does not ear or extract out short and small fringe, the morbidity of booting heading stage, section pest, panicle blast seriously occur, and can cause a large amount of dead ears or half
Dead ears, loss are very big.Rice blast can all occur in entire growth period duration of rice, according to aggrieved period and the difference at position, can be divided into
Seedling pest, leaf pest, section pest, panicle blast and grain pest etc., wherein with panicle blast to yield effect maximum.
It is found by experiment that, tetramycin is combined with fluorine azoles ring bacterium amine to Magnaporthe grisea (Pyricularia oryzae Cav.)
There is synergistic function, prevent rice blast excellent；Pass through certain technological means tetramycin and fluorine azoles ring bacterium amine group
Closing object can be using excipient as agriculturally common dosage form.
