Its time to burn down those herbicide strips in pecan orchards in preparation for the growing season. There are many combinations of herbicide applications you could use. Here are a few for trees of different ages:<\/p>\n

If you have more grassy weeds glyphosate will be the best option for the burndown material. If broadleaf weeds are more of an issue, go with paraquat or glufosinate. Regarding the pre-emerge materials, Prowl is safer to use during the budbreak application than Flumioxazen, which has enough post emergence activity to damage the tender foliage if you get a little wind, which can occur this time of year and Prowl is good on both grasses and broadleaves. Flumioxazen tends to last longer than Prowl. Pindar is a new product for us and offers two modes of action. Like Flumioxazen, Pindar does provide some burndown of existing weeds that Alion does not, but we still suggest you put glyphosate or glufosinate out with it as you usually have some larger weeds that Pindar will not totally kill.\u00a0Pindar does provide broadleaf and grass control but\u00a0over time it did dissipate and weeds started to emerge after about 3-5 months in Dr. Timothy Grey\u2019s trials compared to season long control with Alion.\u00a0 But if you have new trees, it would be a good consideration to rotate with Flumioxazen as your pre-emerge material.<\/p>\n

Regardless of tree age, if you have less than 70-75% bare ground at application, apply your burndown material first and come back with the pre-emerge after the weeds have died down. Otherwise, you can tank mix the two. Pre-emerge materials generally need contact with bare ground to work properly. Most need rainfall with 7-10 days to activate as well.<\/p>\n

There are other weed control options besides those listed above. This is simply one option that seems to work well. Consult the\u00a0UGA Pecan Spray Guide<\/a>\u00a0for more options.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
