around here last year they where promoting a diff rent kin of threshold it was when they got to 250/plant or something like aphid plant days, if you have 10 on day one and 20 day two 40 day three it would add up to 70 and when you got to a level (it might have been 250 also I don't remember right now) then you should spray. so if you had 50 for 5 days you should spray also or 10 fro 25 and so on
