Soil-borne diseases represent an impediment to the sustainable development of agriculture. A soil-borne disease caused by severely impacts species, and soil disinfestation has proven to be an effective management approach. Here, diallyl trisulfide (DATS), derived from garlic, exhibited pronounced inhibitory effects on the growth of tests and contributed to the alleviation of soil-borne diseases in the field. A comprehensive analysis demonstrated that DATS inhibits the growth of by activating detoxifying enzymes, such as GSTs, disrupting the equilibrium of redox reactions. A series of antioxidant amino acids were suppressed by DATS. Particularly noteworthy is the substantial depletion of glutathione by DATS, resulting in the accumulation of ROS, ultimately culminating in the inhibition of growth. Briefly, DATS could effectively suppress soil-borne diseases by inhibiting pathogen growth through the activation of ROS, and it holds promise as a potential environmentally friendly soil disinfestation.

Reductive soil disinfestation (RSD) represents an environmentally eco-friendly approach for controlling Fusarium wilt, a prevalent soil-borne disease. This method not only has the potential to suppress disease occurrence but also to enhance the activity of soil microorganisms and nutrients levels. Soil metabolites play a critical role in shaping microbial community composition and regulating pathogen abundance.

The invasive pathogen persists within nurseries, potentially within buried, infested leaf debris. To determine how the environment-notably soil temperature and moisture levels-affects the epidemiological risk of soil inoculum reserves, we performed laboratory assays assessing how variable conditions impact pathogen survival and its capacity to sporulate. We first established that incubating the inoculum at 4°C increases the number of sporangia produced from infested rhododendron leaf disks.

Less hazardous alternatives to soil fumigants for suppressing soilborne pathogens, such as pathogenic isolates within the () species complex that cause black root rot of strawberry, are urgently needed. A promising alternative is anaerobic soil disinfestation (ASD), in which anaerobic fermentation is induced in soil, leading to production of pathogen-suppressing reduced metal cations (Fe, Mn) and volatile fatty acids (VFAs) before planting. However, little is known about how interactions between amendment composition, soil texture, and neutral to alkaline soil pH influences suppression via soil biogeochemistry.

Background: Soil disinfestation by steaming was evaluated due to its efficacy in controlling or potentially eradicating weed seeds. We exposed two soil types containing aggressive weeds to steam using a soil vacuum steaming method. The aim was to examine whether the method could be used to avoid the spreading of viable seeds to new regions when soil is reused.

Increasing attention has been given to the role of reductive soil disinfestation (RSD) on antibiotic resistance genes (ARGs) in soil. The selection of organic materials in RSD is crucial to the effectiveness of the RSD method. However, the effects of distinct organic materials on ARGs remains unclear.
