Breaking the Ergot Cycle

What Is it?

  • Ergone is a low salt index liquid fertilizer that delivers the right amount of Copper to cereals prior to flowering.
  • The product is formulated with fully water soluble ingredients and OMEX’s proprietary technology that enhances uptake and translocation.
  • The product is available in 10L jugs, 450L and 1000L IBC’s.

When & Why Use It?

  • Ergone is recommended on all cereal crops.
  • Ergone is intended to be sprayed alone or in conjunction with commonly used fungicides.
  • Copper is important for many plant processes including chlorophyll production, photosynthesis, straw lignification, pollen fertility, the pollination process and seed quality.
  • Prairies soils are known for their copper deficiency that ranges from moderate to severe depending on the cropped area.
  • Soil applied copper is mainly intercepted by the root to be beneficial to the crop. Any condition that leads to a poor root growth and development impacts copper uptake.
  • Copper hence needs to be supplied throughout the season through soil application, coating the fertilizer or the seed and foliar.
  • Cereals are very sensitive to copper deficiency especially rye, barley and spring wheat.
  • A correlation has been established between copper deficiency and the prevalence of ergot in cereals.

What To Expect?

  • Ergone improves copper levels in the plant prior to flowering, leading to an improvement of pollen fertility.
  • High pollen fertility guarantees a better and quicker pollination leading to lower chances of contamination by ergot spores. The mechanism of action is called avoidance.
  • Field trials with spring wheat across the prairies showed a reduction of the flowering period by 2-3 days, resulting in a decrease in ergot incidence provided a proper seeding rate is observed.
  • The product contains copper and improves lignification and straw strength and helps prevent lodging.

Application Guidelines

  • Apply Ergone at 1L /ac with a minimum of 10 USgal of water (15 USgal is preferred) at early flowering stage.
  • Recommended alone or tank-mixed with most commonly used fungicide (see compatibility chart). Some combination may be physically compatible but may cause bronzing effect on the leaves.
  • Ergone is a copper containing product and as such should be sprayed with a high water volume, especially if tank-mixed with fungicides that require higher rates of surfactant.
  • Avoid spraying Ergone under hot and dry conditions. Spray preferably late during the day going to the evening. Bronzing from Ergone does not lead to yield losses.
