  • Reduces sugarbeet cyst nematode (Heterodera schachtii) up to 90%
  • Acts as a general bio-fumigant when incorporated into the soil
  • Extremely rapid early growth — ideal for later planting
  • Medium maturity with excellent standability
  • Captures and recycles nutrients
  • Improves soil organic matter and aeration

Sugarbeet cyst nematodes (SBCN) are a recognized problem in sugarbeet production. SBCN populations increase when sugarbeets or other host plants are actively growing. CONCORDE oil radish effectively reduces sugarbeet cyst nematode populations up to 90% when used as a cover crop. Often referred to as a nematode trap crop, CONCORDE oil radish stimulates SBCN cysts containing hundreds of eggs to develop but prevents the nematodes from completing their life cycle. The result is a dramatic decrease in the nematode population because the reproductive cycle is effectively stopped. Rapid and vigorous early plant development is an important component in effective SBCN nematode control. CONCORDE oil radish is the fastest developing oil radish variety available.

Additionally, CONCORDE oil radish has excellent standability and expresses resistance to Columbia Root Knot nematode (Meloidogyne chitwoodi) as oil radishes generally do. CONCORDE oil radish has all the benefits of a conventional cover crop radish: nutrients are captured and recycled as the radish decomposes; natural soil aeration occurs as the radish develops; and soil organic matter is increased when the green material is incorporated into the soil.

CONCORDE oil radish is the choice when SBCN is the primary target and rapid establishment is essential.
MANAGEMENT

  • Planting Date: Late July to September
  • Planting Rate: 25 lbs./acre
  • Planting Depth: ¼” to ¾” (up to 1” if soil is dry)
  • Fertilizer: 30 to 40 pounds N per acre

KEYS to SUCCESS

  • Plant early.
  • Control weeds and volunteer plants. They could be nematode hosts.
  • Be sure to plant at least 25 lbs./acre. Effective control occurs with more plants per square foot as opposed to large root diameter.

  • Multiple nematode control reduces both sugarbeet cyst nematode (Heterodera schachtii) and Columbia Root Knot nematode (Meloidogyne chitwoodi) populations
  • Acts as a general bio-fumigant when incorporated into the soil
  • Rapid early growth
  • Medium maturity
  • Excellent standability
  • Captures and recycles nutrients
  • Improves soil organic matter and aeration

Sugarbeet cyst nematodes (SBCN) are a recognized problem in sugarbeet production. SBCN populations increase when sugarbeets or other host plants are actively growing. CONTROL oil radish effectively reduces sugarbeet cyst nematode populations up to 90% when used as a cover crop. Often referred to as a nematode trap crop, CONTROL oil radish stimulates SBCN cysts containing hundreds of eggs to develop but prevents the nematodes from completing their life cycle. The result is a dramatic decrease in the nematode population because the reproductive cycle is effectively stopped. Rapid and vigorous early plant development is an important component in effective SBCN nematode control. The improved development of CONTROL oil radish is a key advancement over previous radish varieties. CONTROL also has improved standability over other varieties.

Oil radish is generally a poor host for Columbia Root Knot nematode (CRKN) which is a problem in potatoes and many other crops. Reducing CRKN nematode populations over 95% separates CONTROL oil radish from other oil radish varieties. Disruption of the CRKN nematode reproductive cycle results in a dramatic population drop.

Additionally, CONTROL oil radish has all the benefits of a conventional cover crop radish: nutrients are captured and recycled as the radish decomposes; natural soil aeration occurs as the radish develops; and soil organic matter is increased when the green material is incorporated into the soil.

CONTROL oil radish is the best choice for multi-nematode resistance with outstanding plant characteristics and cover crop benefits.

  • Reduces sugarbeet cyst nematode (Heterodera schachtii) up to 80%
  • Acts as a general bio-fumigant when incorporated into the soil
  • Faster initial growth and root development than radish
  • Excellent standability
  • Best use for later planting, where water is limited or where soil conditions are poor
  • Captures and recycles nutrients
  • Improves soil organic matter and aeration

Sugarbeet cyst nematodes (SBCN) are a recognized problem in sugarbeet production. SBCN populations increase when sugarbeets or other host plants are actively growing. MASTER white mustard effectively reduces sugarbeet cyst nematode populations up to 80% when used as a cover crop. Often referred to as a nematode trap crop, MASTER white mustard stimulates SBCN cysts containing hundreds of eggs to develop but prevents the nematodes from completing their life cycle. The result is a dramatic decrease in the nematode population because the reproductive cycle is effectively stopped. MASTER white mustard develops more quickly with deeper and faster root development than radish. This fast initial growth is important when planting is delayed or water may be limited.

MASTER white mustard contains high glucosinolate levels which is important if MASTER is incorporated into the soil to take advantage of its bio-fumigant properties. During the breakdown of the green material a gas is released that acts as a fumigant which kills free living nematodes and can also kill fungal pathogens.

Additionally, MASTER white mustard has all the benefits of a conventional cover crop brassica: nutrients are captured and recycled as the plant decomposes; natural soil aeration occurs as the mustard root develops; and soil organic matter is increased when the green material is incorporated into the soil.

MASTER white mustard is the best choice for for SBCN control when planting is delayed or planting conditions are less than ideal.
MANAGEMENT

  • Planting Date: Late July to September
  • Planting Rate: 20 lbs./acre
  • Planting Depth: ¼” to ¾”
  • Fertilizer: 30 to 40 pounds N per acre

KEYS to SUCCESS

  • Plant as soon as possible
  • Control weeds and volunteer plants. They could be nematode hosts.
  • Be sure to plant at least 20 lbs./acre. Effective control occurs with more plants per square foot.

  • Reduces Stubby Root Knot nematode (Trichodorus sp. & Paratrichodorus sp.) which is important in potatoes
  • Reduces Root Lesion nematodes (Pratylenchus penetrans) which is important in many agricultural crops
  • Rapid early growth (faster than ryegrass)
  • Can be used for quality forage
  • Soil protection from wind and water erosion
  • Extensive fibrous root system
  • Improves soil organic matter and aeration

PRATEX black oats combine the benefits of a grass cover crop with nematode control. Nematode control is not a usual consideration for determining which cover crop to use, but it should be. Where potatoes are grown, using a cover crop that controls Stubby Root Knot nematodes is an added benefit. Root Lesion nematodes affect most crops by pruning roots, which ultimately leads to yield loss. PRATEX black oats effectively reduce populations of both these nematodes by creating a root environment that is not favorable for reproduction. With no reproduction, nematode levels collapse.

The nematode controlling attributes of PRATEX black oats do not require the crop be plowed down to be effective. This emans that PRATEX black oats can also be utilized for valuable forage. Additionally, PRATEX black oats establish extremely quickly and have an extensive, fibrous root system which helps control weed development while reducing water and wind erosion.

PRATEX black oats are a great choice either alone or in mixtures when nematode control combined with forage production, soil improvement and protection from wind or water erosion are desired.

MANAGEMENT

  • Planting Date: Late July to September
  • Planting Rate: 70-90 lbs./acre
  • Planting Depth: ¾” – 1 ½”
  • Fertilizer: 30 to 70 pounds N per acre

KEYS to SUCCESS

  • Plant as early as possible.
  • Control weeds and volunteer plants. They could be nematode hosts.
  • Be sure to plant at least 70 lbs./acre. Effective control occurs with more plants per square foot.
