Hooded Sprayer Use in Cotton

Posted by romeethredge on June 24, 2011

Lots of new Hooded Sprayers are around for use in cotton fields so we can do a better job controlling pigweeds. Here’s Clint Mims covering some ground with this hooded sprayer. He’s spraying under the hood with a good mix of herbicides and directing another set of chemistries at the base of the cotton plant for optimal weed control and residual. Here’s a link to a video of the hooded sprayer going through the field http://youtu.be/hd4pnIX_vug

Some reminders:  Go slow, keep hood tight on ground, keep pressure low under hood (under 25 psi) , turn spray off before raising hood (Don’t laugh, it’s been done), after turning off spray , keep hoods on ground for a little bit, just a little hesitation before raising hood helps.

See above where a hooded sprayer using paraquat sprayed end rows, and killed some cotton in the cross rows. Other cotton in the field was not affected and weed coverage looked good.

This chart is in the 2011 UGA Cotton Production Guide, here’s a link to it.
