Joi Choi Pac Choi

seeds

Brassica rapa (chinensis group)
(50 days) F-1 hybrid.

Joi’s leaves are much darker green than Prize Choy’s and its basal stem is almost double the thickness, making it so succulent the late Adam Tomash preferred it to all other varieties. Market growers appreciate its uniformity. Suitable both for summer and fall crops, though much less likely to bolt in the fall. Do not disturb the roots when transplanting and space 1' apart. Tested negative for BR and BL.

Additional Information

Pac Choi

About 10,000-14,000 seeds/oz; 350-490 seeds/g.

Also known as Bok Choy. Pac Choi is a good crop for microgreens.

Asian Greens

Days to maturity are from emergence after sowing; from transplant, subtract 20 days.

Culture: Wire hoops and row cover keep out flea beetles and are a must for pristine salad or braising mixes!

Diseases:

ALTS: Alternaria Leaf Spot
BL: Black Leg
Black Rot
BSR: Bacterial Soft Rot
DM: Downy Mildew

Major pests: Cabbage Looper, Diamondback Moth, Imported Cabbageworm
Cultural controls: control cabbage-family weeds near crop fields, till under crop debris of early-season brassicas after harvest.
Material controls: Spinosad, Bt.

Pest: Flea Beetle
Cultural controls: floating row covers, mulch with straw, time plantings for fall harvested crops only, crop rotation, perimeter trap cropping.
Material controls: Spinosad, Pyganic.

Pest: Cabbage Root Maggot
Cultural controls: time planting to avoid first hatching, use row covers, control weeds.

Major diseases: Black Rot, Alternaria Leaf Spot, Blackleg, Club Root, Downy Milldew, White Mold
Cultural controls: avoid transplanting plants with yellow leaves or v-shaped lesions, crop rotation, destroy crop debris after harvest, avoid overhead irrigation, control weeds, allow for good air movement.
Material controls: Copper.

Note: because of a rule issued by Oregon, we cannot ship brassica packets larger than ½ oz. (14 grams) into the Willamette Valley, except those that have tested negative for Black Leg and Black Rot. Check descriptions for information.

Brassicas

Days to maturity are from transplant date.

Culture: Start brassicas indoors March-May for setting out May-July, or direct-seed in May, or in June for fall crop. Minimum germination soil temperature 40°, optimal range 55–85°. Easier grown for the fall because many varieties perform poorly in hot summers. For better stands in dry conditions, sow in trenches and keep irrigated. Wire hoops and row cover should be used at early stages to keep out flea beetles and swede midge.

Diseases:

BL: Blackleg
BR: Black Rot
BS: Bacterial Speck
DM: Downy Mildew
FW: Fusarium Wilt
FY: Fusarium Yellows
TB: Tipburn
WR: White Rust

Pest and Disease Remedies for all Brassicas

Pest: Cabbage Root Maggot
Cultural controls: time planting to avoid first hatching, use row covers, control weeds.

Major diseases: Black Rot, Alternaria Leaf Spot, Blackleg, Club Root, Downy Mildew, White Mold
Cultural controls: avoid transplanting plants with yellow leaves or v-shaped lesions, crop rotation, destroy crop debris after harvest, avoid overhead irrigation, control weeds, allow for good air movement.
Material controls: Copper.

Disease: Head Rot
Cultural controls: use well-domed varieties, harvest heads when tight, cut stalks at an angle.
Material control: Copper.

Swede Midge—not as cute as it sounds!

Alert! Heading brassicas in the Northeast are seeing consistent damage from swede midge, a tiny gall midge. Its effects result in a non-heading plant. Wire hoops and row cover at early stages of heading brassica crops are becoming crucial for success. Some research also suggests garlic sprays as a possible organic repellent. Consult your Cooperative Extension resources for further information.
