Special Issue Information

Dear Colleagues,

With the development of protected agriculture and continuous cultivation of high-value crops, a large number of pathogenic fungi, bacteria and insect eggs accumulate in the soil. Soil-borne diseases such as fusarium wilt, root rot, bacterial wilt and root-knot nematodes occur frequently. Soil-borne diseases are becoming increasingly serious. Due to the high multiple cropping index, less fallow and crop rotation, soil-borne diseases are more serious in agricultural cultivation in some developing countries than in developed countries, resulting in a significant decline in crop yield and quality, which restricts the cultivation and sustainable development of protected cultivation. Irrational application of pesticides and fertilizers in the management of soil-borne diseases also leads to deterioration of soil quality. Scientific treatment of soil-borne diseases is an important approach to improve the quality of farmland.

This Special Issue welcomes original research papers, short communications and reviews focusing on the following topics: transmission and epidemics of soil-borne disease, diagnosis and identification of soil-borne diseases, pathogenesis of soil-borne diseases, chemical and biological control of soil-borne diseases, soil disinfection technologies, new products of soil fumigants, formulation and application methods for soil fumigants, mode of action of soil fumigants, environmental behavior of soil fumigants, ecological and environmental effects of soil fumigants, economic assessment of soil-borne disease management products and technologies.

Abstract

Organic materials added to soil create anaerobic conditions that can reduce soil-borne pathogens that reduce the yield and quality of agricultural crops. Anaerobic soil disinfestation (ASD) requires relatively large quantities of readily available, inexpensive organic materials. We evaluated the impact of ASD with rice bran and biochar organic materials on changes to the soil’s physicochemical properties, microbial taxa, and strawberry fruit yield. We found that the organic materials applied at different dose rates significantly increased the control effect of the soil Fusarium spp. and Phytophthora spp. to 69–99% and 63–98%, respectively. In addition, ASD significantly increased soil organic matter and ammonium nitrogen contents. Strawberry yield also increased significantly after ASD treatment with biochar applied at 10 t/ha, which was positively correlated with increased soil nutrients and a significant reduction in pathogens. High-throughput gene sequencing showed that ASD significantly increased the abundance of some beneficial microorganisms such as Bacillus, Pseudomonas, and Mortierella, possibly due to changes in the soil’s physicochemical properties that favored their survival. We found for the first time that biochar applied at 10 t/ha could create anaerobic conditions that effectively reduced soil-borne pathogens and increased crop yield. Full article

Abstract

Two types of Trichoderma longibrachiatum Tr58 propagules, conidia and chlamydospores, were added to soils with different moisture levels. The survival dynamics of Tr58 in soils were determined. There are positive linear relationships between soil moisture levels and germination rates of the two propagules. In natural non-sterilized soil, the germination of more than 95% conidia and 60% chlamydospores was inhibited, while a high soil moisture content and sterilization were beneficial to spore germination. The inhibitory effect of soil with 80% moisture content on the germination of chlamydospores was almost completely eliminated after sterilization. Twelve months after the conidia inoculated to the natural soil, the Tr58 propagules decreased continuously, which was hastened in soils with lower moisture content and almost near zero 24 months later, in all soils. In chlamydospore-amended soils, the Tr58 propagules generally showed a dynamic process of decreasing in the first month, increasing in the 2nd month, and then decreasing gradually. The average Tr58 content in chlamydospore-amended soils with 5, 10, 20, 40, and 80% moisture content was 19.2 times that of conidia-amended soils at 12 months. At 24 months, the Tr58 content was about 2.2% of the initial Tr58 content and 114 times that of conidia in soils with 20% moisture content. However, for 80% moisture content, the Tr58 content in soil was 0.0038% of the initial content of Tr58. According to the results of this study, 10–20% soil moisture content was the most favorable for the long-term survival of Tr58, and the survival ability of chlamydospores was stronger than that of conidia and had greater application potential in disease control.

Abstract

Root-knot nematode disease seriously threatens the production of Rui yams, making it important to explore effective management strategies, including the optimal time for disease control and efficient application techniques. In this study, we monitored the dynamics of a root-knot nematode J2 population in the soil using field sampling; moreover, we investigated the dynamics of root-knot nematode disease using a field sampling and visual in situ device based on identifying species of root-knot nematodes in Rui yams. Additionally, experiments pertaining to optimal application time and techniques were conducted in Ruichang and Nanchang. This is the first study to propose that chemical control should be optimally timed, with one application administered at the time of yam seedling flush, and another given approximately 60 days later. Applications of a 41.7% fluopyram suspension (1426 g.a.i./hm²) and a 30% fosthiazate microencapsulated suspension (2925 g.a.i./hm²) achieved disease control effects of 81.56–83.15% and 75.95–78.42%, respectively. Additionally, the comparative analysis demonstrated that using uniform root layer application technology at the optimal time produces a control effect exceeding 80%, which is significantly higher than conventional techniques such as drip irrigation and root irrigation. These results provide theoretical and technical support for the efficient control of root-knot nematode disease in Rui yams. Full article

Abstract

Dazomet (DZ) is a soil fumigant that has been used for decades at many countries, however it was reported to have caused phytotoxicity and reduced crop yield in many countries. In this experiment, in order to clarify whether the diameter of DZ is related to phytotoxicity, this research investigated the degradation rate of DZ with different diameter ranges under three soil types held at 15, 20 or 30% soil water content at 4, 15, 25 or 37 °C, and monitored concentrations of methyl isothiocyanate (MITC) produced when Shunyi soil was fumigated with DZ using the different particle sizes ranges. When the soil water content and temperature increased, the degradation rate of DZ with different particle sizes accelerated. However, the degradation rate of DZ with large particle sizes was still lower than small particle sizes. NO₃⁻-N, available phosphorus (AP), available potassium (AK), pH and silt content in the soil were all significantly positively correlated with <100 μm DZ, and significantly negatively correlated with 300–400 μm and >400 μm DZ. However, organic matter (OM) and sand content produced the opposite result. The maximum concentration of MITC produced by 100–300 μm of DZ in 25 °C Shunyi soil at 30% water content were 102.2 mg/kg at 24 h. DZ produced peaks significantly higher and earlier at 30% than at 20% soil water content. We recommend selecting DZ manufactured with particle in the range of 100 to 300 μm, fumigating at about 25 °C and ensuring that about 30% soil water content is present in the soil immediately after fumigation.

Abstract

Pesticides are considered the most effective way to protect crops. However, irrational use has caused resources waste and environmental pollution. Dazomet (DZ) is a soil fumigant that has been used in many countries for decades, although it has caused occasional crop damage or insufficient control efficacy in some circumstances. In this study, the effects of DZ’s granule size and exposure to various environmental conditions on DZ degradation when used as a fumigant were demonstrated. The degradation rate of DZ was closely related to granule size. The half-life of larger DZ granules was longer than smaller granules with all studied environmental factors. The degradation rate decreased as the DZ usage (90–360 mg/kg) increased and different granule sizes showed the same variation trend. The half-life in each of the five granule size ranges tested decreased significantly as the temperature increased. DZ half-life decreased by 4.67–6.59 times as the temperature increased from 4 to 35 °C. Moreover, DZ usage and temperature affected the half-life of granules >400 and 300–400 μm in diameter significantly more than <100 μm granules. The half-life of all DZ granule sizes was reduced by 13.9–47.4% in alkaline compared to acidic conditions (pH from 9 to 5). Moreover, elevated temperatures could not only promote the production of methyl isothiocyanate (MITC) but accelerate its dissipation. The interactions between DZ granule size, dosage, temperature, and pH provide practical guidance on methods to improve DZ’s efficacy against pests and reduce the risk of phytotoxicity. Full article
