Production and Management Hutchinson, Chad M. [1]. Chloropicrin Soil Fumigation in Potato (Solanum tuberosum L.) Production. SOIL fumigation products were evaluated for potato production (Solanum tuberosum L. var. ‘Vivaldi’) at the Plant Science Research and Education Unit in Hastings, FL. All treatments were arranged in an 8 x 2 x 2 factorial design with four replications. Fumigants were applied 6-7 January, 2004. Fumigation factor treatments were no fumigation, Telone II (56 L ha-1, conventional treatment), chloropicrin (45 kg a.i. ha-1); chloropicrin (67 kg a.i. ha-1); chloropicrin (90 kg a.i. ha-1); Pic-Plus (45 kg a.i. ha-1); Pic-Plus (67 kg a.i. ha-1); and Pic-Plus (90 kg a.i. ha-1). Application method factor treatments were single shank (conventional treatment) and double sweep. Bed preparation factor treatments were non-pressed (conventional treatment) and pressed. Potatoes were planted on 10 February and harvested 26-27 May, 2004. All Pic-Plus rates produced significantly more total and marketable production compared to the Telone II treatment (current standard, 40.5 MT ha-1 total yield). There was no rate of chloropicrin that produced significantly more total or marketable yield than the Telone II treatment. There was no significant difference in total or marketable yield between the Telone II and no fumigant treatment or between the chloropicrin and Pic-Plus treatments at equal rates. Application method had no significant effect on tuber yield or size distribution of tubers. However, pressing the bed significantly improved both total and marketable tuber yield, improved tuber size, and reduced the percent culls. None of the factor interactions was significant. Percent of tuber surface covered with scab in the no fumigant, Telone II, and Pic-Plus (67 kg a.i. ha-1) treatments was 36, 27%, and 1.7% respectively. Pic-Plus treatments improved overall appearance of the tubers at lower rates than chloropicrin treatments.
