It can be stored at room temperature for over 12 months, extending its shelf life by more than 6 months compared to conventional conidiophore agents. This powder significantly increases the expression of five defense enzymes—PAL, PPO, POD, CAT, and SOD—in tomato and rice plants, thereby activating the plant's defense system. It effectively controls bacterial wilt in tomatoes and black-streaked dwarf disease in southern rice, improving the growth of tomatoes infected with bacterial wilt and rice infected with black-streaked dwarf disease. It is suitable for promotion and use as a novel biological pesticide product.

The invention belongs to the technical field of biological prevention and control of plant diseases, and particularly relates to a biological source rhizosphere metabolite phthalic acid and application thereof in prevention and control of sugarcane smut. The invention relates to an application of a biological source rhizosphere metabolite in prevention and control of sugarcane smut. The biological source rhizosphere metabolite is phthalic acid. The key rhizosphere metabolite phthalic acid with efficient and targeted bacteriostatic activity is screened and identified from disease-inhibiting soil, safe and efficient prevention and control of sugarcane smut are achieved by targeted inhibition of germination of pathogenic bacteria chlamydospore, and the key rhizosphere metabolite phthalic acid can be developed as a biological source pesticide and has broad application prospects. And the method has great significance on pesticide reduction, synergism and green development of agriculture.

The product property of the wettable powder is improved by reasonably optimizing the dosage of the DSE chlamydospore and the auxiliary materials, the chlamydospore content in the finished product can reach 2.35 * 10 < 8 > CFU / g, the wetting time is 24.25 s, the suspension rate is 73.8%, and all indexes meet the national standard; the product can be stored for more than 12 months at normal temperature, and the shelf life is prolonged by more than 6 months compared with that of a conventional conidium microbial agent. The powder can remarkably improve expression of five defensive enzymes, namely PAL, PPO, POD, CAT and SOD, in tomato and rice plants, so that a defensive system of the plants is activated, tomato bacterial wilt and southern rice black-streaked dwarf can be effectively prevented and treated, the growth vigor of the tomato infected with the bacterial wilt and the growth vigor of the rice plants infected with the southern rice black-streaked dwarf are improved, and the powder is suitable for being used as a novel biopesticide product to be popularized and used.

The application discloses a method for reversibly inhibiting the maturation of a Porphyra haitanensis filament, and belongs to the technical field of Porphyra haitanensis breeding. The method comprises adding DMTU to a filament culture medium, and provides a method for inhibiting the maturation of a Porphyra haitanensis filament. When maturation is started, the filament culture solution containing DMTU is used to promote the maturation of the filament, so that the growth of the Porphyra haitanensis filament and the formation of sporangial branches can be effectively inhibited. The inhibiting effect is reversible, and normal maturation can be restored after the treatment is stopped. The inhibiting effect is immediately released, and then the precise regulation of the maturation process of the filament is realized, and the large number of "miscarriages" of chlamydospores is effectively prevented. Therefore, the maturation inhibition method has a good application prospect, and has important practical significance and application value for improving the technical level of the Porphyra haitanensis breeding industry and guaranteeing the sustainable development of the industry.

The invention belongs to the technical field of agricultural ecological cultivation and plant protection, and discloses a method for reducing fresh pea root rot in a flue-cured tobacco-fresh pea rotation mode based on synergism of rotation and a microbial agent. The corn is used for replacing the third-year Dahun flue-cured tobacco; in the third year, when the spring crop corn is sown, a Purpureocillium lilacinum and Trichoderma asperellum complex microbial inoculant is applied in a matched manner; after garlic bulbs are harvested, healthy straw and root system residues are smashed and returned to the field, soil humidity is kept, and biological fumigation is carried out; after the corn season, straw is smashed, deeply ploughed and returned to the field. The three measures have a synergistic effect to jointly strengthen the inhibition and removal functions on the pathogenic bacterium dormant bodies of the pea root rot in the soil, and the micro-ecological health of the soil is remarkably improved, so that strong root disease system resistance is provided for later fresh peas. On the premise that an original crop rotation system framework is not damaged, green and efficient ecological prevention and control of soil-borne diseases are achieved.
