Are disinfecting solutions monitored to ensure that effective concentration, pH and temperature are maintained?
How often? Chlorine is deactivated by organic matter, and its activity is affected by the pH of the solution. Clearly, maintaining the correct pH is critical for effective disinfection with acid. • Do you test samples from treated seed lots for bacterial pathogens? Testing procedures are expensive, as significant quantities of seed are needed, and the testing destroys the seed. However, if your supplier is able to provide negative test results for representative samples from their seed lots, it can give you more confidence in their commitment to the disinfection process. Keep in mind, though, that a negative test result does not guarantee that the seed you receive is free of bacterial pathogens. A negative test simply means that on those seeds contained in the test sample, the number of bacteria present was below the detection limit. • Other steps in a disinfection procedure may include seed defuzzing and neutralizing rinses. These steps are used with specific procedures and are not ne
