Dormancy Enhancers & Sprout Control

Minimize peeps, sprouts & bruising

1,4, DMN

About this treatment:

Pressure bruise, shrink and sprout control are quality issues that storage managers face every year. Incorporating a DMN into your storage treatment program can provide unprecedented results in managing these common challenges:

  • Peeps and Sprouts:
    Used alone or in a CIPC-based application program, DMN works internally to delay sprouting by prolonging dormancy.
  • Pressure Bruise and Shrink:
    DMN restores potato dormancy. This lowers the respiration rate, which in turn slows the loss of moisture and solids, diminishing susceptibility to pressure bruise and shrink.

Features:

  • Effective in turning peeps and sprouts black to freshen potatoes for market.
  • Maintains dormancy helps maintain potato firmness. A fresher product appearance results in fewer load rejections or downgrades.
  • Research shows that early application of DMN improves long-term sprout control.
  • Utilize in conjunction with CIPC and clove oil as part of an overall potato storage program.

Clove Oil

Clove Oil

Clove oil is a natural compound potato sprout inhibitor. It is an approved material under the Washington State Department of Agriculture Organic Food Program. In just a few days following its application, most visible sprouts and peeps turn black, dry up and ultimately drop away.

Features:

  • Ideally suited for potatoes that have started to sprout and need to be upgraded for shipping. It rapidly turns most peeps and sprouts brown and black. It is effective on any variety and is temporary in action. This enables growers to freshen the exterior of stored potatoes so that they look rejuvenated and ready for market.
  • Clove oil is a sprout eliminator for organic production and its effects are short term, lasting approximately two to three weeks. To prevent or delay sprouting longer term, apply a CIPC or DMN to the storage.
  • Applied in storage with regular thermo-fogging equipment.
  • Labeled for application as an EC formulation to fresh potatoes prior to packaging for market.

1-Octanol

1-Octanol

Safely and effectively eliminates emerging peeps and sprouts during post-harvest storage that need to be upgraded for premium shipping. It rapidly turns most peeps and sprouts brown and black. This enables growers to freshen the exterior of stored potatoes so that they look like freshly harvested potatoes.

Features:

  • Aggressive on sprouts that have rapidly extend-ed to 3-4 inches in length. The aggressive action uniquely burns down the sprout for complete dry down in a matter of weeks. This gives a grower options to deal with an undesirable situation that would have been economically devastating.
  • Applied in storage with regular thermo-fogging equipment.
  • Upgrades potatoes to reduce rejections.
  • Superior pile penetration for effective control.

CIPC

About this treatment:

In the potato industry, CIPC (Chlorpropham) applied by thermal fogging system in aerosol form is the standard for inhibiting sprouts. Since the 1950s, CIPC has been unmatched for inhibiting peeps and sprouts because of its effectiveness and affordability in the marketplace. IVI has been instrumental in the improvement of the application process, resulting in an enhanced performance of CIPC to inhibit sprouts on potatoes.

Sprout growth contributes significantly to the weight loss in harvested potatoes. Sprouts are responsible for increased respiration leading to more surface moisture affecting quality of the stored potatoes. Sprout suppression is a crucial part of the storage process. For years, the US potato industry has looked to chlorpropham (CIPC) as a reliable post-harvest sprout inhibitor.

Features:

  • Proven in the industry for seventy years as the most reliable, effective, and least costly product used for long term sprout control on stored potatoes.
  • Applied in storage with regular thermo-fogging equipment.
  • Labeled for application as an EC formulation to fresh potatoes prior to packaging for market.

Ethylene Gas

About this treatment:

Ethylene is a natural gas, produced by bacteria and fungi in the soil and by all plants or fruits like apples and tomatoes.

  • Use for onion storage:
    Ethylene gas treatments provide proven benefits for allium growers. The receptors in the onions will bind and release the ethylene molecules and signal a block to cell elongation, controlling sprout growth.

Features:

  • Ethylene gas is the only post-harvest application product available to use for controlling sprout growth on onions.
  • Does not leave a residue on onions which allows for an immediate, market-ready product.
  • There is no re-entry interval (REI), allowing growers and employees to be in and near the storage during treatment.
  • There is no remaining residue in the storage facility, eliminating the need for clean up or sanitizing.
  • It is economical.
  • It is EPA approved.
