Preemergence weed control

cycloate (Ro-Neet)

Rate 3.0 to 4.0 lb ai/A (0.5 to 0.66 gal/A Ro-Neet 6EC)

Time Apply preplant, at-planting or immediately post-planting of the crop. A preplant application may be made in the fall. Use maximum of 0.66 gal/A if applying in the fall and do not reapply Ro-Neet in the spring.

Remarks Apply Ro-Neet to well-worked soil that is dry enough to permit thorough mixing with incorporation equipment. Mechanically incorporate all applications 2 to 3 inches deep or incorporate with sprinkler irrigation water or enough water to penetrate soil 3 to 4 inches within 36 hr after application. Use lower rate on sandy soils and higher dosage on heavier soil. For maximum weed control, plant immediately after application. When cultivating fields where cycloate has been banded in row, use shields to prevent moving untreated soil into treated row. Do not cultivate deeper than the depth of the herbicide incorporation. May be applied with fluid fertilizers or impregnated on dry bulk fertilizers. REI 48 hr.

Caution Injury may result on highly saline or alkaline soils. Avoid overlapping herbicide application or injury can result.

Site of action Group 8: lipid synthesis inhibitor but not an ACCase inhibition

Chemical family Thiocarbamate

ethofumesate (Nortron, Ethotron and other trade names)

Rate 0.125 to 3.75 lb ai/A (0.25 to 7.5 pints/A Nortron 4SC or Ethotron 4SC)

Time Apply preplant or preemergence followed with a light incorporation or sprinkler irrigation (0.5 to 0.75 inch of water). May also apply to bedded soil in the fall. Ethofumesate can be applied postemergence in a tank-mix with glyphosate or Betamix.

Remarks For preplant and preemergence applications, apply 2.25 to 7.5 pints/A (broadcast equivalent), depending on soil type and organic matter content. Effective on most broadleaf weeds, but only fair on nightshade. Good on most grasses, kochia, Russian thistle, and redroot pigweed. Use the higher rate within each soil texture category (see label) on the finer texture soils and/or where kochia or barnyardgrass are expected to be a problem. Refer to the product label to determine compatibility with liquid fertilizers. REI 12 hr.

Caution Temporary injury and/or carryover problems may occur at higher rates. Do not exceed a total of 1 gal/A (broadcast equivalent) in a single season. If soil-applied, do not plant any crop other than sugar beets or ryegrass within 12 months after applying. May rotate six months after low-rate postemergence applications of 12 oz/A or less. Do not apply more than 6 pints/A (broadcast equivalent) on soils with less than 3 percent organic matter. Do not mechanically incorporate under sprinkler irrigation. Moldboard-plow soil the next year before planting other crops.

Site of action Group 15: very long-chain fatty acid synthesis inhibitor

Chemical family Benzofuran
