Proline, Lift and Orthene IFS

— Written By

The following data are from 6 trials conducted during 2009 and 2010 with combinations of Orthene, Proline, and Optimize Lift at recommended rates applied in the seed furrow at planting in 5 gallons of water per acre. I’m not going into detail on this, but I have been getting questions about compatibility of these products. While there are some rather strange things going on in the data set with thrips control, I did not see any interactions with Proline and other treatment factors for peanut yield. Two experiments were in new peanut fields, and there appeared to be no problem with inoculant performance with Proline. I will probably conduct these trials one more time, at these three locations, to make sure I’m not missing something. Although there are a number of interactions I’m not showing, Proline did not seem to negatively affect anything in the trial. Generally there was slight increase in yield, irrespective of other treatment factors. When Lift or Proline was applied, there did seem to be less thrips damage (in absence of Orthene.) This is a visual assessment (done by a weed scientist.) I do need to sort through this in more detail. I hope this helps as you make recommendations. David
