Description

Bactericide for controlling pathogenic bacteria fusarium solani after picking of tsaoko amomum fruits
Technical Field
The invention belongs to the technical field of postharvest preservation of fruits, and relates to a bactericide for controlling postharvest pathogenic bacteria of amomum tsao-ko.
Background
Amomum tsaoko Crevost et Lemaire is a perennial evergreen clustered herb of the genus Amomum in the family Zingiberaceae. The fructus Tsaoko can be used for cooking and can also be used as medicinal materials. As the medical value and the economic value of the tsaoko are gradually known, the market demand is increased, and the planting area and the harvest amount are also increased. However, the mature period of the fresh tsaoko fruits is concentrated, the fruits are mature within 10-12 months, and a large amount of tsaoko fruits are infected by the pathogenic bacterium Fusarium solani in the storage process after being picked, so that the tsaoko fruits are rotten and deteriorated, and serious economic loss is caused. Therefore, the method has to actively and effectively control pathogenic bacteria Fusarium solani, and a bactericide with an inhibiting effect on the pathogenic bacteria Fusarium solani after the strawberries are picked is determined, so that an important reference basis is provided for the storage and management of the strawberries.
Disclosure of Invention
The invention aims to provide the bactericide for controlling pathogenic bacteria of fusarium solani after the strawberries are picked, and the bactericide has a definite and obvious bactericidal effect.
Through research, the invention provides the following technical scheme:
the chemical bactericide for controlling the pathogenic bacterium Fusarium solani after the strawberries are picked comprises any one or more of the following effective components: prochloraz, imazalil, difenoconazole, pyraclostrobin, tebuconazole and azoxystrobin.
Furthermore, the bactericide for controlling the pathogenic bacteria fusarium solani after the strawberries are picked contains the effective component prochloraz.
Furthermore, the bactericide for controlling the pathogenic bacteria fusarium solani after the strawberries are a prochloraz-imazalil bactericide, a prochloraz-carbendazim bactericide or a prochloraz bactericide.
The invention has the beneficial effects that: the bactericide for controlling the pathogenic bacteria Fusarium solani after the tsaoko amomum fruits are picked provided by the invention can effectively inhibit the growth of Fusarium solani hyphae, has a definite and obvious effect, is beneficial to fresh-keeping storage of the tsaoko amomum fruits, and reduces economic loss caused by rotten and deteriorated fruits caused by the Fusarium solani.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below.
Experimental materials and methods
1. Inhibiting effect of single chemical bactericide on pathogenic bacteria
The chemical bactericide single products shown in Table 1 were added to the melt-sterilized PDA medium to prepare a drug-containing medium with a final concentration of 5ppm, 20mL per plate, and an equal amount of sterile water was used as a control. After the medium had solidified, a Fusarium solani cake of 5mm diameter, cultured on normal PDA medium for 7 days, was inoculated into the above plate, sealed with a sealing film, and cultured in an incubator at 28 ℃ for 5 days, and the colony diameter of each plate was measured by the cross method.

Figure BDA0003009487050000021
2. Inhibitory Effect of commercial fungicides on pathogenic bacteria
The commercial bactericides shown in table 2 were added to the PDA medium subjected to melt sterilization to prepare drug-containing media having final concentrations shown in table 2 (the in vitro bacteriostatic use concentration is the highest recommended use concentration of the commercial bactericides), each plate was 20mL, and an equal amount of sterile water was used as a control. After the medium had solidified, a Fusarium solani cake of 5mm diameter, cultured on normal PDA medium for 7 days, was inoculated into the above plate, sealed with a sealing film, and cultured in an incubator at 28 ℃ for 5 days, and the colony diameter of each plate was measured by the cross method.

Second, experimental results
1. Inhibiting effect of single chemical bactericide on pathogenic bacteria
In order to effectively prevent and control the rot caused by the pathogenic bacteria Fusarium solani of the tsaoko amomum fruits, a single product of 10 chemical bactericides is selected, and the inhibition effect of the single product on the growth of the hypha of the pathogenic bacteria Fusarium solani is measured. As shown in fig. 1 and 2, 6 chemical bactericides (prochloraz No. 10, imazalil No. 4, difenoconazole No. 2, pyraclostrobin No. 7, tebuconazole No. 3 and azoxystrobin No. 1) can obviously inhibit the growth of pathogenic bacteria hyphae, wherein the prochloraz has the best inhibition effect on the growth of the pathogenic bacteria hyphae, and then the imazalil, the difenoconazole, the pyraclostrobin, the tebuconazole and the azoxystrobin are sequentially added; in addition, 4 chemical bactericides (No. 5 PAPB, No. 6 iprodione, No. 8 PeeG, No. 9 PC8) could not inhibit the growth of the hypha of the pathogenic bacterium Fusarium solani of the tsaoko amomum fruit.
2. Inhibitory Effect of commercial fungicides on pathogenic bacteria
As shown in FIGS. 3 and 4, 13 selected commercial bactericides can inhibit the growth of pathogenic fusarium solani hyphae, but the inhibition effects are greatly different, wherein the inhibition effects of the imidazole-imazazole (B), the imidazole-imazazole (C), the methionine-thiram (E), the imidazole-carbendazim (H), the prochloraz (A) and the carbendazim (L) on the growth of the fusarium solani hyphae are the best, and the hypha growth can be completely inhibited after 5 days of inoculation; the inhibition effects of chitosan (M), enoyl manganese zinc (K), enoyl azoxystrobin (D) and chlorothalonil (J) are inferior, and the diameter of hypha can be reduced by about 40-55 mm; the inhibition effects of oxatone cymoxanil (G), carbendazim thiram (i), carbendazim + mancozeb (F) are relatively weak. Therefore, the commercial bactericide containing the prochloraz component can effectively inhibit the growth of pathogenic bacteria Fusarium solani after the strawberries are picked.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
