Potential Exposure
Organophosphate fungicide used on
fruits, vegetables and nut crops; also on ornamentals and
greenhouse products.
First aid
Speed in removing material from eyes and skin
is of extreme importance. Eyes: Eye contact can cause dan gerous amounts of these chemicals to be quickly absorbed
through the mucous membrane into the bloodstream.
Immediately and gently flush eyes with plenty of warm or
cold water (NO hot water) for at least 15 minutes, occa sionally lifting the upper and lower eyelids. Get medical
aid immediately. Skin: Get medical aid. Dermal contact can
cause dangerous amounts of these chemicals to be absorbed
into the bloodstream. Wearing the appropriate PPE equip ment and respirator for organophosphate pesticides, imme diately flush skin with plenty of soap and water for at least
15 minutes while removing contaminated clothing and
shoes. Shampoo hair promptly if contaminated. Ingestion:
Call poison control. Loosen all clothing. Never give any thing by mouth to an unconscious person. Get medical aid.
Do NOT induce vomiting. If conscious, alert, and able to
swallow, rinse mouth and have victim drink 4 to 8 oz of
water do NOT induce vomiting but immediately administer slurry of activated charcoal (2 oz in 8 oz of water). If vic tim is UNCONSCIOUnited States OR HAVING
CONVULSIONS, do nothing except keep victim warm. In
some cases you may be specifically instructed by poison
control to induce vomiting by way of 2 tablespoons of syrup
of ipecac (adult) washed down with a cup of water. Do
NOT give activated charcoal before or with ipecac syrup.
Inhalation: Get medical aid. Do not contaminate yourself.
Wearing the appropriate PPE equipment and respirator for
organophosphate pesticides, immediately remove the victim
from the contaminated area to fresh air. If the victim is not
breathing, administer artificial respiration. Do not use
mouth-to-mouth method if victim ingested or inhaled the
substance; give artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other
proper respiratory medical device. If breathing is difficult,
administer oxygen through bag/mask apparatus until medi cal help arrives. Do not leave victim unattended.
Shipping
UN2783 Organophosphorus pesticides, solid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN3018 Organophosphorus pesticides, liquid, toxic,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
In the presence of strong reducing agents
such as hydrides, organophosphates form highly toxic and
flammable phosphine gas. Contact with oxidizers can cause
the release of toxic oxides of phosphorus. Decomposes in
temperatures above 260℃.

Waste Disposal
Destruction by alkali hydroly sis or incineration. Containers must be disposed of properly
by following package label directions or by contacting your
local or federal environmental control agency, or by con tacting your regional EPA office.
Uses
Agricultural fungicide.
Uses
Fosetyl-aluminium (fosetyl-Al) is a systemic fungicide effective in
controlling various Phycomycete diseases, in particular the downy mildews,
Phyfophfhora and Pythium spp. It has also shown useful activity
against several bacterial plant pathogens (e.g. Erwinia amylovara). It is
widely used on a variety of crops including vines, fruit (bananas, citrus,
pineapples, avocados, stone fruit and pome fruit), berries, vegetables,
hops, ornamentals and turf.
Agricultural Uses
Fosetyl aluminum can be used as Fungicide: used on fruits, vegetables and nut crops; also on ornamentals and greenhouse products.

Environmental Fate
Plant. Felsot and Pedersen (1991) reported that fosetyl-aluminum degrades in plants forming phosphonic acid which ionizes to the dianion phosphonate, HPO3–2.
Metabolic pathway
Fosetyl-Al undergoes rapid and extensive degradation and metabolism
in soil, plants and animals. Cleavage of the P-O-ethyl linkage yielded
phosphorous acid, ethanol and naturally incorporated components as the
terminal products (Scheme 1).
Degradation
Aqueous solutions of fosetyl-Al undergo rapid degradation in strong
acidic and alkaline conditions (1) with observed DT50 values of 5 days
(pH 3) to 13 days (pH 13) but exhibit higher stability at pH values
closer to neutrality (Bertrand et al., 1981). However, the results of biodegradability
studies suggest that fosetyl-Al is readily biodegradable in
environmental water (Mead, 1996).
