Summary
-
1.
The decyl alcohol gave effective sprout inhibition at a dosage of 1.9 ml per bushel. Lenticel pitting was observed when dosage was applied in less than three days. Application was by dripping onto a hot plate and recirculating vapors through the storage pile.
-
2.
The decyl alcohol compared favorably with CIPC in controlling shrinkage factors which lead to black spot in storage.
-
3.
The decyl alcohol had no effect on chipping color and tended to give less after-cooking darkening to potatoes.
-
4.
Tubers trated with the decyl alcohol and planted for seed purposes gave varying yearly results. Some years no effect was observed on potato yields and in other years, serious reductions were obtained.
-
5.
Alcohol odors on the potatoes dissipated readily in a five-day period after removal from storage.
