I ordered a set of 25 of the Agdia CymMV+ORSV test strip kits directly from Agdia, $120 for the set of 25 kits plus about $10 shipping so about $5.20 per test.
While $5 per plant is not cheap, I spent many times that amount to purchase each plant. I have about 80 plants, soon to be about 100. I will try to test them all in the next several months and then continue testing as I acquire additional plants.
