The present application relates to the field of microbiological technology, and particularly relates to a pathogenic bacterium causing root rot symptoms of red heart disease of Astragalus membranaceus and application thereof, the pathogenic bacterium is Fusarium sp. Fusarium sp. FUS-001-2025, preserved in China General Microbiological Culture Collection Center on March 16, 2026, with the preservation number of CGMCC No. 42529; it is determined to be a new recorded strain of Fusarium sp. through morphological and molecular identification, and the bactericide sensitivity determination shows that 25% silthiofam·prochloraz has the strongest inhibition effect, 25% bromothalonil, 50% azoxystrobin and 70% methylthiophanate have significant inhibition at high concentrations. The present application provides an important pathogenic bacterium resource for the pathogenic mechanism, disease resistance evaluation and development of control agents of red heart disease of Astragalus membranaceus.

The invention discloses a pesticide suspending agent containing bromothalonil and dithianon and a preparation method thereof, and belongs to the technical field of pesticide preparation processing. The pesticide composition provided by the invention is prepared from the following components in percentage by mass: 1%-35% of bromothalonil, 1%-35% of dithianon, 1%-10% of a wetting agent, 1%-10% of a dispersing agent, 0%-10% of a performance improving agent, 0.1%-2% of a suspending aid, 1%-10% of an anti-freezing agent, 0.1%-0.6% of a defoaming agent, 0.05%-0.6% of a preservative, 0.1%-0.5% of a pH regulator and the balance of deionized water. According to the pesticide suspending agent disclosed by the invention, the selected wetting agent is combined with the special performance improving agent and the specific dispersing agent, so that the problems of heat storage and long-term stability of the suspending agent containing the low-melting-point bromothalonil can be well solved.

The invention relates to the technical field of pesticide slow release, in particular to a bromothalonil-containing bactericidal slow-release preparation and a preparation method thereof. The preparation is composed of a double-shell core-shell slow-release microcapsule suspension, a dispersion stable component and a water-phase continuous phase, the microcapsule takes bromothalonil crystal particles as a core, dopamine hydrochloride is subjected to oxidative polymerization in an alkaline water phase and is deposited to form a polydopamine inner shell, a chitosan-sodium tripolyphosphate ionic crosslinking outer shell is constructed on the surface of the polydopamine inner shell, and the dispersion stable component and the water-phase continuous phase are subjected to cross-linking to form the double-shell core-shell slow-release microcapsule. Chitosan is combined with a polydopamine interface through hydrogen bonds and electrostatic interaction and is cross-linked and cured with sodium tripolyphosphate; the synergistic double-shell structure enables the system to maintain low viscosity under a high-solid-content processing condition and maintain integrity under pumping, spraying and high shearing, the encapsulation efficiency of 80-99% is achieved, and low-initial-stage burst release and long-acting slow release are both considered, so that the coupling contradiction among rheology controllability, interface stability and mechanical strength of a slow-release pesticide suspension system is relieved; the bactericidal composition is suitable for agricultural scenes requiring persistent sterilization.
