Pecan Herbicide Strip Applications – Lenny Wells<\/h2>\n

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

Trees 1-2 Yrs:<\/em><\/strong>
\nAt\u00a0<\/b><\/u>budbreak<\/b><\/u>:<\/b><\/u>
\nGlufosinate + Prowl
\nMay\/June:<\/b><\/u>
\nGlufosinate\u00a0or<\/b>\u00a0Glyphosate\u00a0or<\/b>\u00a0Paraquat +
\nFlumioxazen (Tuscany, Chateau)
\nAugust\/September<\/b><\/u>
\nGlufosinate\u00a0or\u00a0<\/b>Glyphosate\u00a0or<\/b>\u00a0Paraquat +
\nFlumioxazen (Tuscany, Chateau)<\/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.<\/p>\n

Trees 3 Yrs and Up:<\/strong><\/em>
\nAt\u00a0<\/b><\/u>budbreak<\/b><\/u>:<\/b><\/u>
\nGlyphosate\u00a0\u00a0or<\/b>\u00a0Glufosinate\u00a0or<\/i><\/b>\u00a0Paraquat + Alion (5 oz)*
\nJuly\/August<\/b><\/u>
\nGlyphosate\u00a0or<\/b>\u00a0Glufosinate\u00a0or<\/b>\u00a0Paraquat +Alion (5 oz)
\n*After 1<\/i>st<\/i>\u00a0season using\u00a0<\/i>Alion<\/i>\u00a0drop down to 3.5\u00a0<\/i>oz<\/i>\u00a0rate<\/i><\/p>\n

Trees 3 Yrs and Up Rotate in Alternate Years With:<\/em><\/strong>
\nAt\u00a0<\/b><\/u>budbreak<\/b><\/u>:<\/b><\/u>
\nGlyphosate\u00a0or<\/b>\u00a0Glufosinate\u00a0or<\/i><\/b>\u00a0Paraquat + Flumioxazen
\nJuly\/August<\/b>
\nGlyphosate\u00a0or<\/b>\u00a0Glufosinate\u00a0or\u00a0<\/b>Paraquat + Flumioxazen
\nSeptember (if needed)<\/b><\/u>
\nGlyphosate\u00a0or<\/b>\u00a0Glufosinate\u00a0or\u00a0<\/b>Paraquat + Flumioxazen<\/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. Pindar would be a good material to rotate in when weed control in herbicide strips is desired in the dormant season. Pindar is a combination of oxyflurofen, a PPO MoA, and pinoxsulam, a ALS MoA, with both having PRE and POST activity. Pindar\u2019s residual may not last as long as indaziflam\u2019s but\u00a0Pindar will still provide 3-5 months residual control<\/strong><\/em>,\u00a0 which is quite good. The only real problem I see with Pindar is that the label states\u00a0it can only be applied after harvest and up until the emergence of green leaf tissue<\/em><\/strong>, which provides a short window for its use. Since bud-break has arrived we are about out of that window. However, Pindar is a good option for growers who want to keep their strips clean over the dormant season.<\/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
