We have been looking at recently sprigged pastures this past month to determine weed control needs. We can use Diuron immediately after sprigging, but for most everything else, the pasture needs to be established. So, when is it established?<\/p>\n

Sprigging Bermuda<\/strong><\/p>\n

There are a few ways to look at this. One way to look at it is, if you can pull on the plant and it snaps off \u2013\u00a0rather than pulling up roots and all \u2013 then it is \u201cestablished.\u201d There are other definitions of establishment based on runner length. Many of our herbicide labels answer this question.\u00a0The label may say it is considered established when runners reach 8 \u2013 10 inches. Sometimes labels\u00a0describe\u00a0establishment with days after sprigging and\u00a0say,\u00a0\u201cuse only on bermudagrass established\u00a0for 60 days.\u201d<\/p>\n

The pasture pictured above has 8-10 inch\u00a0runners in 40% of the pasture and the rest was 3 \u2013 4 inch runners. In terms of safest postemergent application, UGA Extension Weed Scientist Dr. Patrick McCullough says, the 2,4-D and Weedmaster products will be the safest to use on immature bermudagrass during establishment. However, we are too risky to apply these products now, so mowing will be our only option here until we can buy some time on establishment.<\/p>\n

Sometimes the label will indicate how long after sprigging we can use a herbicide. Generally, when Bermuda sprigs reach 8 – 10 inches or you can pull the sprig and it snaps (without putting up the root) it is considered established.<\/figcaption><\/figure>\n

Seeding Bahia<\/strong><\/p>\n

Here is some TifQuik Bahia that was drilled in mid April. It\u2019s only at 3\/10 of an inch of rain since then, but coming up good. We have a more variety of weeds here, and automatically lose any option with mesulfuron since it\u2019s Bahia. Some seedlings are still emerging, but most of it is 3 -4 inches. The rule of thumb here is when grass is 8 \u2013 10 inches tall, it is considered established and safer to apply herbicides<\/strong>. In this situation, we would mow throughout the growing season, then come in the fall with a phenoxy herbicide\u00a0to start control.<\/p>\n

Bahia reaching 8 – 10″ in height is generally established. It is recommended to mow throughout the season then use herbicide toward the end.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"
