Why would you do a salvage spray? Also, is there anything that should/can be done for peanuts dug last week to help with yield? I am assuming there is not, but wanted to ask.
A salvage spray is for someone that has peanuts still in the field that are not dug. So farmers might begin to see leaf spot coming in even though they think they had everything controlled. I might not be using the word “salvage” very well. The point is, sometimes in the fall, especially under poor conditions when digging is delayed, disease epidemics can sneak up on us. Late leaf spot is the best example. So with an epidemic started, is there anything that can be done to hold leaves on the plant and prevent pod shed. Barbara and I have had some questions about leaf spot beginning to show up during the past few weeks. With poor digging conditions and concerns about when farmers will be able to dig, the question is will an application of fungicide now be helpful. Applying fungicide could help keep plants healthy enough to prevent pod shed in some cases. That’s what I meant by using that terminology. Some growers have 1,000 acres remaining in the field to dig. When it dries up should they spray some of those fields because it will take a while to dig them all. A sprayer can get through the field more quickly than a peanut digger and late spray (salvage in my terminology) might help. David
See Barbara Shew’s comments in previous Peanut Note.
Right now there is nothing anyone can do with peanuts already dug. Vines will often hold on for 2 weeks are longer depending on weather conditions. Hopefully we will dry out some late next week. Farmers will need to lift peanuts prior to harvesting in many fields and that almost always results in losing some pods. But it is necessary to do this to get vines out of the muddy soil to dry prior to harvesting. I have always heard “if you move them you will lose them.” But lifting will help more than it will hurt. Growers will experience substantially higher cleaning costs because pods that are dug after this weather event will be quite dirty. Those on top of the ground might actually have less dirt (it is no longer soil at this point) but the pods will become discolored the longer they stay in the field. But there is nothing labeled to keep fungi or bacteria from growing on pods at this point. So, there is nothing that can be done right now.
