The pesticide used for aerial
applications in 2014 is is an organophosphate under the brand
name "Trumpet." The main component of Trumpet is
Naled, which is a cholinesterase inhibitor containing DDVP
(Dichlorvos). Naled is toxic to fish, birds, and other wildlife.
DDVP is classified by the State of California under Prop 65 as a
chemical that causes cancer (class 2B carcinogen).
The UC Davis MIND Institute's recently published CHARGE Study shows association
between maternal exposure to agricultural pesticides, specifically
organophosphates, and autism in offspring. According to the study,
pregnant women who lived in close proximity to fields and farms
where organophosphates were applied experienced a two-thirds
increased risk of having a child with autism spectrum disorder or
other developmental delay. According to principal
investigator, researcher, professor, and Vice Chair of the
Department of Public Health Sciences at UC Davis, Irva
Hertz-Picciotto, we need to find ways to reduce exposures to
chemical pesticides, particularly for the very young and
especially during gestation.
The District Manager has indicated that for 2006
"Pyrethrin/PBO is similar to that used in 2005, with potentially
different concentrations. (6% py-60% pbo or 5% py-25% pbo or other
formulations depending on the label)." Also, Suspend SC is being used as a
perimeter/ residual treatment. The active ingredient is
Deltamethrin, a pyrethroid. It consists of:
The pesticide used for ground applications in 2005 was Pyrenone 25-5, which consists of:
5% pyrethrins
25% piperonyl butoxide (PBO)
70% unknown.
According to the EPA pyrethrins cause more instecticide
poisenings than any other class of pesticides except one.
PBO is classified as a possible human carcinogen because it caused
tumors in laboratory tests.
Pyrethrins disrupt the normal functioning of sex hormones while
PBO affect the functioning of hormone related organs.
The pesticide used for aerial
applications in 2005 was Evergreen 60-6, which consists of:
The original label provided by the company and over the Internet did not have the information regarding "Use in Mosquito Control"and the information regarding ground application and aerial application. The company has two labels, one for the general use or general public which omits reference to mosquito control and one label that contains the information regarding mosquito abatement for distribution to mosquito abatement districts. The company's rationale is that they do not want non-mosquito folks using EC 60-6 for mosquito control unless it is their profession.
