Silver scurf, black dot, and Fusarium are molds, and all molds spread through the air by sending mold spores airborne. Potato growers’ storages have ventilation systems designed to circulate lots of air, and circulating air spreads these mold diseases.

State-funded university research and more than eight years of success in storages across North America have proven that Humigation reliably removes mold spores from the air, and Humigators are the only air cleaners specifically optimized for potato storage. With no filters to change, Humigators run nearly maintenance-free for years. The spread of these diseases can be stopped by cleaning the mold spores out of the air as it is circulated.

IHT offers a complete line of Humigators for all storage sizes.

1,4GROUP, Inc.

Sprout and peep control, pressure bruising and shrink are quality issues that storage managers face every year. Incorporating 1,4SIGHT into your storage treatment plan can provide unprecedented success in managing these common storage challenges.

1,4SIGHT can be used as a standalone product or to supplement your CIPC sprout control regimen. It works internally to delay sprouting activity, whereas CIPC works externally to prevent peeps from sprouting. Together, they extend dormancy while controlling sprouts. 1,4SIGHT penetrates through the potato skin to restore its dormancy. Dormancy lowers the respiration rate, slowing the loss of moisture and solids, thereby diminishing shrink and susceptibility to pressure bruise. Restoring dormancy may also shorten the post-harvest “sweat period.” Maintaining dormancy helps retain potato firmness, resulting in fresher-appearing potatoes and fewer load downgrades.
