How Important IsEarly Season Weed Competition?
Can one wait until 4-leaf stage of cotton to initiate weed control?
Depends upon: Weed species
Weed density
Growing conditions
![Page 30: 2001 Cotton Production Workshop](https://reader036.vdocument.in/reader036/viewer/2022062518/56814420550346895db0be17/html5/thumbnails/30.jpg)
How Important IsEarly Season Weed Competition?
About 33 to 66% of the time we can initiate
weed control at the 3 to 4 leaf stage of cotton.
If in doubt, apply DNA + Cotoran or Staple
The other 33 to 66% of the time we need a soil-
applied herbicide or 2 overtop RU applications.

Nutsedge Control Programs:
1) 2 applications of glyphosate prior to 5th leaf followed by conventional chemistry including 2 lb ai MSMA directed
2) 1 application of glyphosate or Staple Plus prior to 5th leaf followed by 2 lb ai MSMA directed or glyphosate
3) Zorial or Staple?????
