1) Generally, there should be no major problems mixing Orthene (acephate) with paraquat cracking treatments (Peanut Science 2014 41:58-64).
2) UPI is in a sold out position for Storm 4SL herbicide. However, Storm is in UPI's production schedule for next year. No worries though since growers can make their own Storm if need be. 1.5 pt/A of Storm would be equivalent to 1 pt/A of Ultra Blazer 2SL + 1 pt/A of Basagran 4SL. FYI, when making your own Storm cocktail for mixing with paraquat, I prefer 1 pt/A of Ultra Blazer + 0.5 pt/A of Basagran. 0.5 pt/A of Basagran still helps "safen" the peanuts but this new ratio will be slightly more active on the weeds.
3) Helena has been actively promoting a product called ENC (Ele-Max Nutrient Concentrate) to be used in combination with paraquat cracking sprays. According to Helena, the use of ENC will help the peanuts recover faster from paraquat injury. As far as I can tell, ENC is a fertilizer solution (11-8-5 + various micros). We are currently evaluating this product and its potential benefits. Preliminary results from 1 trial in Attapulgus this year would suggest that the use of ENC resulted in less peanut injury (leaf burn) at 3 DAT (Figure 1) but no differences were detected at 7 DAT (Figure 2). Way too early for a yea or nay recommendation at this point!!! More to follow as additional data is collected.

4) Guess what? When it rains on peanuts that were treated with Valor, especially at cracking, you get crop injury. It happens all the time, regardless if they were irrigated immediately after application or not. Unless something funky has happened (i.e. sprayer problems, excessive rates, misapplication, etc.), research results and on-farm experiences since 2001 would suggest that is very likely that the peanut plants will recover from Valor injury with no yield loss. For more info and injury pictures, refer to my June 3, 2013 blog on this very same issue.
