See your seed dealer for the most recent variety recommendations.

Use seed treated with Thiram or captan seed protectants.

For control of Pythium damping off, use seed treated with Apron XL LS seed protectant.  For control of damping off and seedling blight caused by Pythium spp., Fusarium spp. and Rhizoctonia spp., use seed treated with Apron MAXX RTA.   
Good germination is obtained when soil temperatures are at 10 to 29°C.

Sow seed 1.5 to 2.0 cm deep in rows 30 to 38 cm apart. Precision seed or thin to leave 5 to 7.5 cm between plants. This results in a plant population of 400,000 plants/ha (160,000/acre) and requires about 7 kg/ha (2.8 kg/acre) of seed.

A soil test is necessary to determine phosphate and potash requirements. Use the Vegetable Production Guide: Nutrient Management (PDF) for fertilizer recommendations based on soil test results. At time of seeding, broadcast and disc in 55 kg/ha (22 kg/acre) nitrogen, all of the phosphate and potash and 4.5 kg/ha (1.8 kg/acre) boron.

A deficiency of boron causes black pitting, surface cankers, heart-rot and dry rot.

Beet Disease Management

Raised warty or scab-like growths on the beet root with cracking between the scabs.

Control

  • Avoid soils with a history of potato scab.
  • Rotate with grass or cereals.
  • The disease occurs most commonly in dry soils. Frequent, light irrigation will reduce infection but care must be taken not to encourage excessive growth which can result in oversized and cracked roots, causing serious damage to the crop.

This fungal disease, which is closely related to the one causing black root of radish, may cause an early seedling blight resembling post-emergence damping-off. Later in the season, if wet conditions occur, a black decay may develop on mature roots.

Control

  • Avoid growing beets in poorly-drained fields.
  • Rotate with other crops such as corn, cereals or unrelated vegetables.
  • Use fungicide-treated seed.
  • Delay seeding until soil has warmed up in the spring.
  • Use tolerant beet varieties.

Beets have a high boron requirement. A deficiency causes black cankers in roots.

Control

Consult the Vegetable Production Guide: Nutrient Management (PDF). Do not plant cucumbers on soil that has been treated with boron.
