Beet Seed, red or table

clopyralid (Stinger)

Rate 0.094 to 0.125 lb ae/a (0.25 to 0.33 pints/a Stinger)

Time Apply in 10 gal or more total spray volume when seed crop has at least two true leaves.

Remarks SLN label WA-970033. Use above rates for annual weeds 1 to 2 inches high. Make spot applications up to 0.66 pints/a to Canada thistle.

Caution Apply after most thistle basal leaves emerge but before buds form. Re-treat as necessary up to eight-leaf stage of crop growth, but do not exceed 0.66 pints /a Stinger per growing season. Crop safety data are limited; use only when crop injury is acceptable. Follow rotational crop restrictions on label. Avoid spray drift to sensitive crops. Do not use any part of the treated field, including seed, seed screenings, hay forage, and stubble, for human or animal consumption.

Site of action Group 4: synthetic auxin

Chemical family Pyridine

cycloate (Ro-Neet 6-E)

Rate 3 to 4 lb ai/a (4 to 5.4 pints/a Ro-Neet 6-E)

Time Apply preplant to soil dry enough to thoroughly mix; immediately incorporate 2 to 3 inches deep by cross-disking or using a rotary tiller.

Remarks Use on mineral soil only; seed may be planted immediately.

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

Chemical family Thiocarbamate

EPTC (Eptam 7E)

Oregon and Washington only

Rate 2.0 to 3.0 lb ai/a (2.25 to 3.5 pints/a Eptam 7E)

Time Apply postemergence after transplant leaves emerge or as a layby application at time of last cultivation.

Remarks SLN labels OR-160009 and WA-140001. Product must be incorporated either by rainfall/irrigation or by mechanical means. Eptam has little to no postemergence activity, so emerged weeds must be controlled by incorporation equipment, other herbicide, or hand-weeding near the time of application.

Caution Do not feed or graze table beet forage or fodder. No portion of the treated field, including seed, seed screening, hay forage, and stubble, may be used for human or animal consumption. Do not exceed 3.5 pints EPTAM 7E per acre per crop (except for irrigation applications in the Pacific Northwest Region where two applications of 3.5 pints may be made).

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

Chemical family Thiocarbamate

ethofumesate (Nortron SC)

Western Oregon and Washington only

Rate Consult label.

Time Apply preplant incorporated, preemergence, or postemergence tank mixed with phenmedipham (Spin-Aid). Postemergence treatment may be repeated 4 weeks after first application.

Remarks SLN labels OR-160002 and WA-010002. Crop may be injured under unfavorable environmental conditions or when higher rates are used.

Caution Do not feed or graze table beet forage or fodder. No portion of the treated field, including seed, seed screening, hay forage, and stubble, may be used for human or animal consumption.

Site of action Group 16: unknown

Chemical family Benzofuran

fluazifop (Fusilade DX)

Washington only

Rate 0.063 to 0.25 lb ai/a (4 to 16 fl oz/a Fusilade DX)

Time Apply to actively growing grasses.

Remarks SLN label WA-040006. Identify grasses; adjust rates for susceptibility and stage of weed growth as label instructs. Results often are erratic on grasses stressed from lack of vigor, drought, high temperature, or low fertility. More mature grasses and quackgrass can be controlled but may require two applications. Annual bluegrass and all fine fescues resist treatment.

Caution Do not exceed 32 oz/a per season. Do not apply if rain is expected within 1 hour. Rotational grass crops such as corn and cereals may not be planted within 60 days of the last application. Grazing any plant product or residue is prohibited.

Site of action Group 1: acetyl CoA carboxylase (ACCase) inhibitor

Chemical family Aryloxyphenoxypropionate

phenmedipham (Spin-Aid)

Rate 0.5 to 1 lb ai/a (3 to 6 pints/a Spin-Aid)

Time Apply any time red beets have four to six true leaves and before weeds have two leaves.

Remarks Avoid applying when daytime weather changes rapidly from cool and cloudy to warm and sunny, or if beets are stressed from insect, disease, or cultivation injury. Tip burn or temporary growth retardation and chlorosis may occur, although plants usually recover within 10 days.

Caution Restricted use. Preharvest interval is 60 days. Avoid using more than 7 gal water per quart of herbicide in spray tank; this can cause the herbicide to precipitate.

Site of action Group 5: photosystem II inhibitor

Chemical family Phenylcarbamate

quizalofop (Assure II)

Rate 0.035 to 0.083 lb ai/a (5 to 12 fl oz/a)

Time Apply at optimum growth stage listed on label.

Remarks Identify susceptible grasses and add 4 quarts crop oil concentrate or 1 quart nonionic surfactant/100 gal spray mix. Grass control may be reduced if applied immediately before or after applying a broadleaf herbicide.

Caution Do not mix with or apply with any other pesticide except as specified on label. Do not apply to plants stressed from lack of moisture, cold, or injury from herbicides, insects, or disease. Do not use any treated part of crop for food or feed. Do not exceed 25 fl oz/a per season.

Site of action Group 1: acetyl CoA carboxylase (ACCase) inhibitor

Chemical family Aryloxyphenoxypropionate

sethoxydim (Poast)

Rate 0.28 to 0.47 lb ai/a (1.5 to 2.5 pints/a Poast)

Time Apply at optimum growth stage listed on label.

Remarks Identify susceptible grasses and add 2 pints/a nonphytotoxic crop oil concentrate to improve leaf absorption. Control often is erratic on grasses stunted or stressed from drought, high temperatures, or low fertility. Resistant grasses include annual bluegrass and all fine fescues, but quackgrass can be suppressed.

Site of action Group 1: acetyl CoA carboxylase (ACCase) inhibitor

Chemical family Cyclohexanedione

S-metolachlor (Dual Magnum)

Rate Consult label
