+Means followed by the same letter are not significantly different according to Fisher’s Protected LSD test at P<= 0.05. Data are pooled over experiments and cultivars.

You have seen these data before, but it is always good to be reminded of some of the interactions. In the majority of settings whatever you apply in the seed furrow will most likely give you enough thrips suppression that you don’t have to worry about the negative impact of paraquat on yield. The exception might be using a seed treatment only, but few growers are going to use this approach and few growers are going to leave off some in-furrow product. There was a lot of thrips damage in these trials when aldicarb (Temik) was not used.
