That is your baseline: They have to be absolutely free of diseases and pests. That is the only acceptable metric. There isn't any kind of variance allowed. Thank you for that.
I'll turn to the PMRA.
It has been reported that, with some of the chemicals used to control mites, some of those mites are now showing resistance. When that begins to happen with a well-known chemical that has been successful, it's kind of like an evolutionary arms race. That's just simply what happens. When a pest such as a mite begins to exhibit those kinds of traits, where it is steadily becoming more resistant to a long-accepted type of chemical treatment.... When the PMRA is doing its assessments of approved treatments, is it looking at the safe rate of application and whether it has to reassess whether more has to be used?
Do you ever consider that if you continue using a certain chemical, you're going to start doing more harm than good? How does this factor into your long-term thinking?
