in Combination with Other Products (Field Fumigant) Interim Recommended Permit Conditions 2016a.
"Or a compound known as methyl iodide can be applied with chloropicrin
, using drip irrigation," Ajwa adds.
Our earlier research developed dose-response data for InLine (61% 1,3-D and 33% chloropicrin
) (Klose et al.
In some cases, particularly chloropicrin
and MITC, the sampling intervals were greater than the RfD interval.
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.
Of the fumigants registered in the state, only 1,3-D (alone or in combination with chloropicrin
or an MITC generator) is an approved treatment in nurseries with medium- to coarse-textured soils (table 1).
MB:Pic: methyl bromide with chloropicrin
(98:2, 67:33 or 50:50)
The major alternatives to methyl bromide such as 1,3-D and chloropicrin
are heavily regulated due to the potential for adverse health effects to workers and nearby populations, which has complicated the transition away from methyl bromide.
has excellent fungicidal properties with some broad-spectrum activity, and it can be applied as the sole active ingredient for crops that are primarily under disease pressure.
Currently, metam sodium remains a viable component in alternative fumigant mixes with chloropicrin
; it is more easily incorporated uniformly as a liquid than the dazomet granular formulation.
To control soilborne diseases and weeds, California strawberry fields have long been fumigated with methyl bromide (MB) plus chloropicrin
Although all of these treatments are effective, one of the most effective treatments is chloropicrin
