The present application belongs to the technical field of plant disease prevention and treatment, and particularly relates to a biocontrol bacterium for preventing and treating Guaiacum officinale anthracnose, a fermentation liquor, a biocontrol bacterium agent and application. Bacillus velezensis A biocontrol bacterium is isolated and screened from a microbial resource on a healthy Guaiacum officinale leaf, and is classified and named as Bacillus velezensis , which is preserved in the China General Microbiological Culture Collection Center on March 28, 2025, and has a preservation number of CGMCC No.34038; the biocontrol bacterium provided in the present application has good antagonistic effects on Colletotrichum gloeosporioides causing Guaiacum officinale anthracnose, on Stemphylium botryosum causing Guaiacum officinale leaf spot disease, on Botryosphaeria dothidea, on Alternaria alternata and on Pestalotiopsis versicolor capable of causing plant diseases. The biocontrol bacterium, the fermentation liquor and the biocontrol bacterium agent provided in the present application have potential application prospects in preventing and treating Guaiacum officinale anthracnose.

The invention discloses a parasitic wasp-friendly multifunctional trichoderma asperellum ZJ12 and application thereof, the preservation number of the strain is CCTCC (China Center For Type Culture Collection) NO: M2025805, and the strain has broad-spectrum and efficient antagonistic activity; various phytopathogens such as fusarium oxysporum, fusarium solani, fusarium pseudograminearum, verticillium dahliae, tea pestalotiopsis, phytophthora nicotianae, northern leaf spot helminthosporium bombycis and globulosporium melanocarpum are efficiently inhibited, and a good prevention and treatment effect is shown in a potting prevention effect experiment; the biocontrol microbial inoculum shows transboundary prevention and control potential to lepidoptera pests (plutella xylostella and cabbage caterpillars) and has good biological safety to natural enemy insect parasitic wasps (chrysalis pupae and lateral cotesia manilensis), and the problem that an existing biocontrol microbial inoculum is single in function is effectively solved.

Disclosed in the present invention is a use of a 2-cyano-3-aminoacrylate compound in control of fungal diseases caused by Pestalotiopsis-like fungi. The compound exhibits generally ultrahigh ex-vivo antifungal activity against Pestalotiopsis-like fungi, including Pestalotiopsis, Neopestalotiopsis, and Pseudopestalotiopsis. Phenamacril exhibits a median effective concentration (EC50) ranging from 0.1455 to 0.6025 μg / mL, a mean value of 0.2800 μg / mL and a standard deviation of 0.095 μg / mL against 56 strains of Pestalotiopsis-like pathogenic fungi isolated from Camellia sinensis, Prunus persica, and Vitis vinifera. The Phenamacril suspension formulation spray treatment scheme for Camellia sinensis provided by the present invention can significantly increase tea yield, and provide a basis for controlling diseases caused by Pestalotiopsis, Neopestalotiopsis, and Pseudopestalotiopsis pathogens in tea plantations as well as for monitoring fungicide resistance.

This invention provides a *Trichoderma guiyuan* strain B10 and its applications, relating to the field of agricultural microbial control technology. The *Trichoderma guiyuan* strain B10 is deposited at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC No. 3.25634. This invention overcomes the shortcomings of existing technologies. This strain can inhibit the pathogenic fungi *Neoplasmosis polychaete*, *Neoplasmosis polychaete*, *Neoplasmosis spp.*, *Botrytis cinerea*, and *Metacarpus* spp. of garlic leaf spot disease, while simultaneously promoting the growth of garlic plants, exhibiting both disease resistance and growth-promoting functions in seedlings.

The application discloses an arecoline ester derivative, a preparation method and application thereof, relates to the technical field of chemical pesticides, and has a brand-new molecular structure, and the bacteriostatic activity and insecticidal activity of the arecoline ester derivative are significantly enhanced compared with arecoline; the arecoline ester derivative has certain inhibiting effects on Puccinia recondita, Diplodia natalensis, Gibberella saubinetii, Pyricularia grisea, Phomopsis vexans, Physalospora piricola, Pestalotiopsis versiflorea, and Colletotrichum gloeosporioides; and the arecoline ester derivative also has certain insecticidal activity on Aedes aegypti larvae.
