The present invention relates to the field of pesticides, and discloses an application of a benzaldehyde thiosemicarbazone compound and a bactericide, the benzaldehyde thiosemicarbazone compound has a structure represented by a formula (I), in the formula (I), A is CH or N; r1 is selected from halogen; and R2 and R3 are respectively and independently selected from alkyl groups of C2-C6. The benzaldehyde thiosemicarbazone compound provided by the invention can effectively prevent and treat plant fungal diseases, has an excellent prevention and treatment effect on plant diseases caused by fungi such as magnaporthe oryzae, ustilaginoidea virens, rhizoctonia solani, fusarium graminearum and fusarium pseudograminearum, and has a very good market development prospect. Formula (I)

The application discloses application of Pantoea agglomerans RMM02 and a product thereof in prevention and treatment of rice smut. Pantoea agglomerans The classification name of the Pantoea agglomerans RMM02 is , the preservation number is GDMCC No. 65516, the preservation unit is Guangdong Microbial Culture Collection Center, and the preservation time is November 29, 2024. The Pantoea agglomerans RMM02 is separated from a soil of a rice smut occurrence plot, and is screened through indoor confrontation test and has significant inhibitory activity on Ustilaginoidea virens. Through indoor bacteriostatic test, it is shown that the active bacteria have significant inhibitory activity on Ustilaginoidea virens. Through indoor and field tests, it is shown that the bacteria have significant inhibitory effect on growth of Ustilaginoidea virens, and can control development of a disease during a field smut occurrence period. A biocontrol fungicide prepared after fermentation of the bacteria can effectively prevent and treat smut hazards, and guarantees high yield and high quality of rice.

The utility model relates to the technical field of preparation of false smut prevention and control fungicide, in particular to raw material treatment equipment for preparation of false smut prevention and control fungicide, which comprises a raw material treatment box, a filling port arranged on the upper surface of the raw material treatment box, a servo motor arranged on the right side of the filling port, a driving shaft connected with an output shaft of the servo motor, and a stirring shaft arranged on the outer wall of the driving shaft. The tail end of the driving shaft is connected with a fixed bearing; an auxiliary mixing assembly is arranged in the stirring shaft and comprises a moving groove formed in the stirring shaft, a rotating shaft is slidably mounted in the moving groove, mixing blades are fixedly mounted on the outer wall of the rotating shaft, an elastic winding rope and a limiting piece are arranged between the adjacent mixing blades, and the elastic winding rope is located in the moving groove. The raw material mixing and stirring treatment effect can be further improved through the matching of the stirring shaft and the auxiliary mixing assembly, so that the microbial agent mixing treatment effect is ensured, and the stirring uniformity is also ensured.

The application discloses a Ustilaginoidea virens dominant strain HEB07 and construction of a Ustilaginoidea virens pathogenic bacterium and millet interaction space-time atlas, relates to the technical field of biology, and the strain is screened and verified, the strain has the infection breadth of different millet varieties and the infection pathogenic sensitivity and survival rate of any millet variety, and has high affinity of recombination transformation of a GFP fluorescent label, so as to constitute a gene recombination strain using a green fluorescent protein GFP and explore the Ustilaginoidea virens pathogenic bacterium and millet interaction dominant strain. The application can provide important technical support for cloning research of millet disease-resistant genes, and provide strong scientific basis and technical means for cultivating millet varieties with high resistance to Ustilaginoidea virens.
