Soil Pathogen Presence Testing (Phytophthora, Fusarium)
In agriculture and forestry testing, ensuring soil health is paramount for sustaining healthy plant growth. Soil pathogens such as Phytophthora and Fusarium can significantly impact crop productivity and tree health by causing root rot and other diseases that lead to yield losses.
The presence of these pathogens in agricultural or forest soils necessitates accurate detection methods. At our laboratory, we employ advanced molecular techniques like real-time PCR (polymerase chain reaction) for the precise identification and quantification of Phytophthora and Fusarium species within soil samples.
Our testing process begins with a thorough sample collection, which involves digging up soil from various points in the field or forest to ensure a representative sample. The collected soil is then carefully processed in our clean rooms to avoid contamination. DNA extraction is performed using standard protocols approved by international standards such as ISO 14683 and ASTM D7920.
The extracted DNA undergoes amplification through real-time PCR, which allows us to detect the specific genes associated with Phytophthora and Fusarium species. This technique provides a high level of specificity and sensitivity, enabling even trace amounts of pathogens to be detected.
Our testing methodology ensures compliance with international standards like ISO 17025 for our laboratory certification and IEC 62304 for medical device software requirements, which are critical in ensuring reliable results. The use of real-time PCR technology also allows us to monitor the effectiveness of any interventions aimed at controlling these soil pathogens.
The results from this testing are presented as detailed reports that include quantitative data on the presence and concentration levels of Phytophthora and Fusarium species in the tested soil samples. These reports serve as valuable tools for agricultural and forestry professionals to make informed decisions regarding crop health, disease management strategies, and potential remediation efforts.
Our approach not only helps in understanding the current state of soil health but also aids in tracking the effectiveness of interventions over time. This data is crucial for maintaining sustainable practices that ensure long-term productivity and resilience against environmental challenges.
