Velum Prime

Overview

Put nematodes where they belong: in the history books with NEW Velum™ Prime nematicide and make yield-robbing nematodes a worry of the past. It is the first and only non-fumigant nematicide registered to suppress nematodes in potatoes in Canada. To give your potato yield a chance at becoming one for the ages, integrate it into your nematode protection program today.

Velum Prime helps to sustain high plant vigour and maximize crop yield through suppression of nematodes with the added benefit of providing in-season early blight protection. It is easy to use and comes in a liquid formulation with low use rates that makes it ideal for use with existing in-furrow application equipment.

AUDPC - Area Under the Disease Progress Curve equals the sum of the amount of diseased leaf tissue over a set time period; a low AUDPC is ideal as it represents better control (in comparison to a high number).

Application Tips

What are Nematodes?

  • Nematodes are microscopic, whitish to transparent invertebrate worms; also known as roundworms or eelworms
  • Without treatment, many nematode species can cause extensive damage to potato crop roots – to the point where yields are reduced by up to 80 percent

Application Rates


Protection Against Rate Timing
POTATO AND OTHER TUBEROUS AND CORM VEGETABLES: Arracacha, arrowroot, artichoke (chinese and jerusalem), canna (edible, Queensland arrowroot), cassava (bitter & sweet), chayote (root), chufa, dasheen (taro), ginger, leren, potato, sweet potato, tanier (cocoyam), turmeric, yam bean (jicama, manoic pea), yam (true)

Application Tips

For soil applications (in-furrow) using ground equipment:
  • Spray specified rate in a 10 - 15 cm band in-furrow at planting and cover with soil. For best results uniformly spray the band over the seed-pieces and soil
  • Apply in 50 - 150 L of water per hectare

Packaging:

  • Formulated as 500 g/L suspension concentrate
  • 4.04 L jug, 2 X 4.04 L case
  • Each 4.04 L jug treats 20 ac.

Crop Restrictions:

Do not replant to alfalfa for 14 days after application. All other crops may be replanted immediately following the last application of Velum Prime.

Resistance Management

Do not apply more than the maximum seasonal rate for each specific crop from any combination of products containing fluopyram. Do not apply more than 500 g fluopyram/ha per year, regardless of formulation or method of application (soil or foliar).

Any nematode or fungal population may contain individuals naturally resistant to Velum Prime and other Group 7 nematicides/fungicides. A gradual or total loss of nematode control may occur over time if this product is used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed. To delay nematicide/fungicide resistance:

  • Where possible, rotate the use of Velum Prime or other Group 7 nematicides/fungicides with different Groups that control the same pests
  • Use tank mixtures with nematicides/fungicides from a different group when such use is permitted
  • When Velum Prime is applied as a soil application use another mode of action for the first foliar fungicide application
  • Avoid consecutive applications of Velum Prime or other Group 7 nematicides/fungicides in a season. Alternate applications with fungicides having a different mode of action
  • Nematicide/fungicide use should be based on an integrated disease management program that includes scouting, historical information related to pesticide use and crop rotation and considers host plant resistance, impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other chemical control practices
  • Early blight pressure should be monitored throughout the growing season. Heavy disease pressure may require additional systemic foliar fungicide applications
  • Monitor treated nematode populations for resistance development
  • Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area
