Quality Control and Quality Assurance Quality control (QC) can be defined as a procedure (or set of procedures) intended to ensure that a manufactured product adheres to a defined set of quality criteria – and ultimately meets the requirements of the client or customer. Quality assurance (QA) attempts to improve and stabilize production (and associated processes) to avoid, or at least minimize, issues which led to the defect(s) in the first place. Known for its outstanding quality throughout the market, Viridaxis is constantly checking the quality of its parasitoids. But Viridaxis is not stopping here: we focus equally on QA in order to be able to supply year round millions of parasitoids when more traditional production processes break down. Our quality standards comply with International Organisation of Biological Control (IOBC) rules, but we ultimately strive to meet the requirements of the grower and to fulfill his expectations to the upmost possible. An aliquot of every shipment leaving our production facility is kept for several weeks and all testing results are logged. QC and QA are not only the base of good business, but are fundamental for the expansion of biological and integrated pest control in the agricultural sector. Low-quality products are not only of low efficiency for the grower who applies them, but can harm the global efforts to render agriculture more sustainable. Key concepts in our daily quality care include Standard Operating Procedures, climate control during production and transport, calibration, process control, product control, yield, emergence rate and traceability.
