Cole Crop Seed

clomazone (Command 3ME)

Broccoli and cabbage seed

Rate 0.25 to 0.5 lb ai/a (0.67 to 1.3 pints/a Command 3ME)

Time Apply to soil before transplanting broccoli or cabbage, or direct-seeding cabbage. Place plant roots below the herbicide barrier when transplanting.

Remarks Use lower rate for coarse soils and higher rate for fine soils. See label for crop rotation restrictions and application requirements to avoid crop injury or vapor drift to sensitive plants. Cabbage may be chlorotic temporarily. Before using, ask seed company whether the cultivar has good tolerance to Command. Avoid overlaps while spraying.

Caution Do not mix or apply within 300 ft of landscapes, orchards, vegetable or berry plots, or property lines to prevent chemical trespass. Do not graze cover crops. Preharvest interval is 9 months for food or feed. Do not let livestock graze on treated pea vines or vine trash.

Site of action Group 13: inhibits DOXP synthase

Chemical family Isoxazolidinone

clopyralid (Stinger)

Washington: Broccoli, cauliflower, and cabbage seed

Oregon: Broccoli, broccoli raab, Brussels sprouts, cabbage, cauliflower, cavalo broccolo, Chinese (bok choy) cabbage, Chinese broccoli, Chinese mustard cabbage, Chinese (napa) cabbage, collards, kale, kohlrabi, mizuna, mustard greens, mustard spinach, rape greens seed

Rate 0.094 to 0.125 lb ae/a (0.25 to 0.33 pint/a) in Washington; maximum rate in Oregon is 0.188 lb ae/a (0.5 pints/a)

Time Apply in 10 gal or more total spray volume when seed crop has at least two true leaves. Spot applications up to 0.66 pint/a may be applied to Canada thistle. Apply after most thistle basal leaves emerge but before buds form.

Remarks SLN labels OR-090018 and WA-970033. Use for annual weeds 1 to 2 inches high. Re-treat as necessary up to eight-leaf stage of crop growth; do not exceed 0.66 pint/a Stinger per growing season. Crop safety data are limited; use only where crop injury is acceptable. Follow rotational crop restrictions on label. Avoid spray drift to sensitive crops. SLN labels OR-090018 and WA-970033.

Caution Do not apply with other herbicides that are emulsifiable concentrates, or oil-based adjuvants, particularly during heat-stressed periods. Extreme growing conditions such as drought or near freezing temperatures prior to, at, and following time of application may increase the risk of crop injury. See label for crops allowed. Do not use any part of treated field, including seed, seed screenings, hay forage, or stubble for human or animal consumption.

Site of action Group 4: synthetic auxin

Chemical family Pyridine

fluazifop (Fusilade DX)

Washington only-cabbage, kale, and Chinese cabbage seed

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 and adjust rates for susceptibility and stage of weed growth as label instructs. Control often is erratic on grasses stunted or stressed by drought, heat, 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. Do not plant rotational grass crops such as corn and cereals 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

oxyfluorfen (Goal 2XL, Goal Tender several trade names)

Transplanted broccoli, cauliflower, and cabbage seed

Rate 0.25 to 0.5 lb ai/a

Time Apply soon after final soil preparation and before transplanting through the treated layer with minimal soil disturbance.

Remarks Use lower rate for coarse soils with less than 1% organic matter. Leaves that contact treated soil may be injured temporarily. Injury may be severe if transplants are stressed by temperature, disease, fertilizer salts, nematodes, insects, pesticides, and storage conditions or if planting small transplants grown in 1-inch cells. After transplanting, apply at least 0.25 inch overhead moisture. Plant only crops listed on label within 10 months after treatment. Grazing crop residue or treated fields prohibited.

Site of action Group 14: protoporphyrinogen oxidase inhibitor

Chemical family Diphenylether

quizalofop (Assure II)

Chinese cabbage seed only

Rate 0.069 to 0.17 lb ai/a (5 to 12 oz/a Assure II)

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 apply within 14 days of flowering. 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 portion of crop for food or feed. Do not exceed 25 fl oz/a per season.

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 by drought, heat, or low fertility. Resistant grasses include annual bluegrass and all fine fescues, but quackgrass can be suppressed.

Caution Do not exceed 3 pints/a per season.
