Disinfectants and potato ring rot control

American Journal of Potato Research (impact factor: 1.23). 01/1960; 37(10):325-337. DOI:10.1007/BF02855148 pp.325-337

ABSTRACT 1.

Mercuric chloride (1:500) and Semesan Bel (1 lb./4 gal.) were superior to the other materials tested as cutting-knife disinfectants.

2.

The quaternary ammonium compounds of the general formulation alkyl tolyl methyl trimethyl ammonium chloride were very efficient
in the disinfestation of jute, wood, and metal surfaces when instantaneous killing action was not required.

3.

When cut sets of a susceptible potato variety were placed in a contaminated potato bag. a high percentage of ring rot appeared
in the succeeding crop.

4.

Contaminated potato bags soaked in tap water transmitted bacterial ring rot to fewer cut sets than did unsoaked bags.

5.

Under the conditions of these experiments, approximately 250 bags could be safely treated in 40 gal. Hyamine 2389 (300 ppm).

6.

Although some of the materials which were treated as seed-piece disinfectants considerably reduced the amount of ring rot
in the succeeding crop, they were quite phytotoxic and cannot yet be recommended for commercial use.
