These agents, formulated from Bacillus velezensis MD360, Bacillus subtilis MD288 and Bacillus simplex MD315, were evaluated for their effects on antibacterial activity, seed germination, plant growth, disease control and yield. The results showed that in the plate confrontation assay, the composite strains MD360 + MD315 and MD288+MD315 inhibited Fusarium graminarum by 57.44% and 55.74%, respectively, corresponding to improvements of 2.10% and 5.50% over their single-strain counterparts. Germination tests showed that seeds treated with the composite agents achieved germination rates of 90.87% (MD360 + MD315) and 90.10% (MD288 + MD315), which did not differ significantly from either the chemical agent fludioxonil or the blank control. Field assessments of maize growth revealed that at 30 days after sowing, plants treated with MD360+MD315 displayed significantly greater plant height (70.86 cm), stem diameter (29.75 mm), and above-ground fresh weight (60.20 g) than other treatments. By 60 days after sowing, MD360 + MD315 continued to outperform both the blank control and fludioxonil treatment, with plant height, stem diameter, and above-ground fresh weight reaching 216.70 cm, 33.17 mm, and 640 g, respectively. In disease control trials, the MD360+MD315 treatment demonstrated the best control effect against stalk rot, achieving a disease control efficacy of 67.70%, which was significantly higher than that of the chemical agent fludioxonil after field inoculation with F. graminarum. Moreover, yield measurements indicated this treatment significantly increased ear length and yielded the highest grain production of 692.42 kg per 667 m2, corresponding to a 14.45% increase over the control. In conclusion, the synergistic interactions among different Bacillus strains enhanced the efficacy of the composite seed coating agent in promoting maize growth, controlling disease, and increasing yield, offering new insights for the design of composite Bacillus seed-coating agents.

The compatibility of nine chemical fungicides commonly utilized for peanut southern blight control with B. velezensis YJ02 was evaluated using the dilution plating method and colony counting technique. The in vitro toxicity of compatible fungicides and B. velezensis YJ02 against S. rolfsii was determined via the toxic medium method, and the optimal mixing ratio of compatible fungicides to B. velezensis YJ02 was selected based on the toxicity ratio. Pot and field experiments were further conducted to verify the synergistic control effect of the screened composite formulation against peanut southern blight. The results demonstrated that three fungicides, namely thifluzamide, azoxystrobin, and trifloxystrobin, maintained excellent compatibility with B. velezensis YJ02, and thifluzamide exhibited the highest toxicity against S. rolfsii among them. The composite formulation consisting of B. velezensis YJ02 (1× 102 CFU/mL) and thifluzamide (0.1 mg/L) at a volume ratio of 5:5 showed a significant synergistic effect with a toxicity ratio of 1.95. In pot experiments, the high-concentration 5:5 composite formulation (the final concentration was 0.5× 108 CFU/mL B. velezensis YJ02 and 5 mg/L thifluzamide) achieved the optimal preventive control efficacy, which was 55.24% and 46.04% higher than that of B. velezensis YJ02 and thifluzamide applied alone, respectively. Notably, the preventive efficacy of all treatments was significantly better than their corresponding curative efficacy. In field experiments, the control efficacy of the aforementioned high-concentration 5:5 composite formulation was comparable to that of thifluzamide applied at the recommended field dosage, while reducing the application amount of thifluzamide by more than 90%. This study provides a specific technical strategy and theoretical foundation for the green and efficient management of peanut southern blight, contributing to the sustainable control of this soil-borne disease in peanut production.

The primary pathogens responsible for this disease are Fusarium oxysporum and F. solani. In this study, antagonistic strains B205 and B207 were screened out from 228 bacterial strains isolated from soil samples by the plate confrontation method. The two strains exhibited average inhibition rates of 60.0% and 61.2% against F. oxysporum, and 61.4% and 63.5% against F. solani, respectively. Furthermore, pot experiments demonstrated that these strains had substantial control effects on A. macrocephala root rot disease, with preventing rates of 52.6% for B205 and 76.0% for B207. In addition to their biocontrol capabilities, the optimal concentration for B205 and B207 strains to promote the germination of A. macrocephala seeds was determined to be 1× 109 CFU/mL, and the optimal treatment time was 10 minutes. When seeds were treated with the fermentation broth of B207, significant improvements were observed in various germination indicators compared to the control. Specifically, the germination potential, germination percentage, radicle length, germination index and vigor index increased by 64.2%, 35.3%, 37.2%, 59.0% and 119.9%, respectively. Although B205 fermentation broth also led to higher germination indicators than the control, only the vigor index showed a statistically significant increase. Pot experiments further revealed that both B205 and B207 strains could promote the growth of A. macrocephala seedlings. In particular, B207 treatment significantly increased the plant height, fresh weight, leaf number and root vitality of A. macrocephala plants, with an increase rate of 27.2%, 37.9%, 24.0% and 145.9%, respectively. It also showed a significant promoting effect on the number of buds and the aboveground dry weight. In addition, both B205 and B207 strains can produce IAA, and the amount of IAA produced by B205 and B207 in DF+ medium were 29.58 μg·mL-1 and 25.62 μg·mL-1, respectively, which were significantly higher than the control of 7.12 μg·mL-1. Through 16S rDNA and gyrB gene sequence analysis, strains B205 and B207 were identified as Bacillus velezensis. This study indicates the potential of both B. velezensis B205 and B207 in preventing disease and promoting growth of A. macrocephala. Among them, B207 emerges as a particularly promising microbial strain with biocontrol potential in the production of A. macrocephala.

In order to determine the safety of chlorantraniliprole to the parasitoid, the acute toxicity of chlorantraniliprole to the adults was measured, and the behavioral effects of chlorantraniliprole at field-recommended concentrations on T. chilonis were evaluated in laboratory. The results showed that chlorantraniliprole was at a low risk level to T. chilonis with LC50 of 177 mg/L, but long-term treatment significantly reduced the lifespan by 1.75 d. The parasitoid exhibited Holling type Ⅱ functional response, with an instantaneous attack rate of 1.343, a maximum parasitism capacity of 57.471 eggs/d, which was reduced by 1.25 times when the wasps were treated with chlorantraniliprole. The treatment not only reduced the host selection rate of T. chilonis adults significantly, but also significantly extended the host search and location time. Although the treatment had no significant effect on the mating success rate, it significantly extended the mating detection and courtship time, and decreased the duration of copulation time. The treatment had no significant effect on oviposition duration and offspring sex ratio, but significantly increased the pause time during ovulation. In conclusion, the field recommended concentration of chlorantraniliprole has a negative effect on host search and location and oviposition behavior of T. chilonis, which has to be considered in balancing the compatibility of biological and chemical control.

The findings are expected to provide references for the mass-rearing, storage, and application of T. dendrolimi. In this research, the Trichogramma insects were either maintained a 30-day diapause or kept in a 30-day cold storage. Seven biological indicators were measured: the number of parasitized host eggs, the proportion of wasp eggs laid on the first day, the number of wasp eggs in ovary, the proportion of mature wasp eggs, longevity, oviposition duration, and duration of laying behavior. The results showed that, compared with the wasps maintained at normal temperature, diapause and cold storage significantly increased the number of eggs in ovary and lifetime eggs, and decreased the proportion of eggs laid on the first day. Diapause significantly increased the proportion of mature eggs and longevity in T. dendrolimi, while refrigeration led to a decline in both indicators. In addition, diapause treatment significantly shortened the time required for laying behavior, while cold storage increased the time required. However, no significant differences in oviposition duration were observed between the three treatments. Compared with cold storage wasps, diapause T. dendrolimi were superior in all the indexes investigated in this study. When the storage duration was 30 days, diapause obviously improved the overall quality of T. dendrolimi, while cold storage had a certain degree of negative impact.

Field trials were conducted to determine their control efficacy against C. oleifera anthracnose, and the organic acid content in AJ was measured to explore the antimicrobial mechanism. The results showed that the inhibitory effects of all five types of AJ gradually increased with higher application rates and longer exposure time. Among them, AJ using camellia seed meal exhibited the strongest antifungal activity. At a concentration of 15%, it achieved an inhibition rate of 100% against C. siamense, outperforming the prochloraz 1000-time dilution treatment. Field trials indicated that treatments with AJ using camellia seed meal, pineapple peel, and mixed ferment extracts all delayed the onset of the disease compared to the control group. Camellia seed meal ferment extract showed the most significant control effect, with an efficacy of 71.3% at 15% concentration, though still lower than that of the prochloraz treatment. The ferment extracts were rich in organic acids such as acetic acid, lactic acid and malic acid, with acetic acid content being the highest in tea seed meal ferment extract at 176.29 mg/mL. In conclusion, this study provides an economical and effective alternative for controlling C. oleifera anthracnose.

Notably, the combination of T. longibrachiatum YP7 with pyraclostrobin (1 μg/mL) exhibited an inhibition rate of 92.77% against F. verticillioides, a synergy coefficient of 1.62, and a field control efficacy of 76.27%. Similarly, the combination of strain YP7 with carbendazim (0.01 μg/mL) resulted in an inhibition rate of 92.18%, a synergy coefficient of 1.61, and a field efficacy of 73.48%. The control efficacy of both combinations was significantly superior to that of the individual fungicide treatments, indicating a marked synergistic effect. This study provides a novel and practical integrated approach for the green management of maize sheath rot by combination of biocontrol agents and fungicides.

Due to the fact that the past naming of the species in the order Lefavirales was not based on the binomial nomenclature, the ICTV Research Group on Baculoviridae and Nudiviridae revised the species names of the viruses in this order in 2023. Here we introduced the revision principles of naming the baculovirus species: the new name of a virus species composes of two words, the first one is the name of the genus to which the species belongs, the second one is a contraction of the first 2―4 letters of the host’s genus name followed by the epithet of the host species in the genitive form, while the names of viruses and virus isolates remain the previous form before this revision. We further explained the importance of understanding and distinguishing the virus and the virus species for correctly spelling the virus names. The naming method for baculovirus species is also applicable to the members of Nudiviridae. This article is helpful for the Chinese readers to correctly understand and use the names and spelling rules of these virus species when reading literature, writing papers, and submitting nomination documents of new viruses to ICTV.

Subsequently, pot experiments were conducted to evaluate tits control efficacy against tobacco black shank. Furthermore, hyphal morphology of Phytophthora nicotianae after exposure to GXHZ16 was observed using scanning electron microscopy (SEM), antimicrobial activity of crude lipopeptides from GXHZ16 was assessed through mycelial growth rate assays, and PCR detection was used to identify genes encoding lipopeptides. Then, the labelled strain GXHZ16-gfp was obtained through the green fluorescent protein (gfp) tagging, and its colonization dynamics in rhizosphere soil and roots of tobacco plants were investigated. The results showed GXHZ16, identified as Bacillus subtilis, exhibited a control efficacy of 52.21% against tobacco black shank, and caused abnormal hyphal morphology of P. nicotianae. The crude lipopeptides of GXHZ16 strongly inhibited the growth of P. nicotianae, and GXHZ16 was found to contain genes encoding lipopeptides such as plipstatin, fengycin, and surfactin. In addition, GXHZ16 stably colonized the tobacco rhizosphere soil and roots, with colonization densities of 25.20× 106 and 12.93× 105 cfu/g, respectively, on the 28th day after inoculation. These findings provided a theoretical foundation for the further exploration and industrial development of GXHZ16.

China is the country with the largest area of biological control of corn borer using Trichogramma in the world. However, the control efficiency with different Trichogramma species or strains varies significantly. In this experiment, four Trichogramma strains from two species, i.e., Hubei strain, Shaanxi strain, and Shandong strain of T. ostriniae and Jilin strain of T. dendrolimi screened in laboratory with high performance for parasitizing Asian corn borer eggs were employed for field release in consecutive 2 years. Results showed that the control with Hubei strain of T. ostriniae was the best, with average control efficiency of 68.31%, followed by Shaanxi strain and Shandong strain of T. ostriniae, with control efficiency of 63.03% and 62.32%, respectively. Jilin strain of T. dendrolimi had the lowest control, with control efficiency of 47.07%. There were significant differences among the four Trichogramma strains in the parasitic rates of eggs and egg masses, number of corn borer larvae per hundred plants, decrease rates of damaged plants, corn borer larvae and the boring holes. The results may shed light on the biological control of the Asian corn borer. Reference | Related Articles | Metrics | Comments（0）
