Chloropicrin and Chloropicrin blends are found to be some of the most effective in disease management and nematode suppression for sweet potato growers. Chloropicrin aids in the prevention of plant stunting in the field which are caused by multiple stress factors.
These factors include soil-borne diseases such as:
- Potato Scab
- Soil Rot
- Black Root Rot
Effects from soil borne pests combine to reduce yield and crop quality.

We specialize in a well-rounded and complete fertility program designed for sweetpotato production.
Dry Fertilizer: Ground Control Command
Ground Control Command is a poly-coated dry fertilizer, provided by Haifa, can be customized for any analysis and coated from 1-16 months. It offers a more uniform extended release and leaching protection.
The poly-coated fertilizers release plant nutrients slowly and continuously throughout the growth cycle. A single application of GC-Command controlled release fertilizer will supply optimal levels of nutrients for an extended period of time.
Liquid Fertilizer: Liberty Acres
Liberty Acres Fertilizer fertigation grade liquid fertilizer blends supply all key crop nutrients in a single blend that is compatible in a micro-irrigation system.
Foliar Nutrition: Metalosate Powered by Albion Technology
Balchem’s Metalosate Powered by Albion Technology uses natural amino acids to chelate the minerals. They are rapidly absorbed, translocated, and metabolized by plants upon application.
- Increased tuber set
- Improved quality grades through uniformity
- Increased skin firmness and quality
- Longer shelf life
Treated vs. Untreated:
Drip irrigation on sweet potatoes is considered a good practice for several reasons.
- It allows for direct watering during dry weather or on sandier soils
- Drip irrigation can uniformly apply water and minimize water usage and runoff
- Liquid fertilizer and water can be applied straight to the root zone
- Lastly, it allows the grower to inject fertilizer late in the season to push it further.
Let TriEst Ag guide you with choosing the right irrigation system for your sweet potato growing plans. We have decades of experience designing drip and fertigation systems that are completely manual to fully automated. We also offer mobile pump/filter trailers and skid options to accommodate field rotations.
