Emissions of chloropicrin
were lower than 1,3-D emissions (data not shown) because of the lower amount of chloropicrin
applied and its faster degradation; following an application of Telone C35, it's 1,3-D that is the major concern for worker safety in an emissions surge.
The experiment included 10 treatments with 1,3-D in a split plot design with surface treatments as the main plots and two application shank types as the subplots, as well as an unfumigated control and a methyl bromide plus chloropicrin
standard for comparison (table 2).
Pic-Clor 60: fumigant product containing 60% chloropicrin
and 39% 1,3-D
Currently about 68% of the California strawberry acreage is fumigated with alternatives to methyl bromide, primarily drip-applied mixtures of 1,3-D plus chloropicrin
(InLine, Pic-Clor 60) or chloropicrin
emulsified formulation (Pic-EC) (CADPR 2011).
use, since December 2012, is restricted by U.
is an effective soil disease control agent when used alone at 100 to 300 pounds per acre.
Alternative fumigants permitted for use in California strawberries are 1,3-dichloropropene (1,3-D), chloropicrin
and, as of December 2010, methyl iodide.
These chemicals can react with fumigants such as methyl bromide, 1,3-D, chloropicrin
and iodomethane (methyl iodide) to form nonvolatile compounds by dehalogenation (Gan, Yates, Becker, et al.
