Molecular strcuture

 

PRINCIPAL USES:  Glean Weed Killer is recommended for selectivecontrol of weeds in wheat (pre- and/or postemergent to crop) and barley (postemergent to crop) as well as reduced tillage fallow preceding wheat.  Controls most broadleaf and some grass weeds at 1/6 and 1/2 ounce product/acre. Glean is intended for use on land having a soil pH of 7.5 or lower, and dedicated primarily to the production of wheat and barley.

 

APPLICATION METHOD(S):  Preemergence or early postemergence treatments show the most activity on annual grass weeds and broadleaf weeds. Later postemergence treatments are effective on most broadleaf weeds but less effective on grasses.  Treatments may be made with aerial or ground equipment.

 

EFFICACY:

Important Weeds Controlled:  Velvetleaf, pigweed, mustards, shepard's purse, lambsquarters, Canada thistle, sunflower, henbit, plantain, smartweed, curly dock, Russian thistle, chickweed, cocklebur and many others. It has activity on most broadleaf weeds and some annual grass weeds. Certain perennials like Cirsium arvense are sensitive.

Wild oats, cheat and nightshade are tolerant of this material. Broadleaves are more susceptible than grasses.  Shallow incorporation may improve grass control but may also reduce broadleaf control.  Plant death is often slow.
