2593-15-9 Usage
Description
Etridiazole (20) was first described in 1969 and is a
contact fungicide for control of soilborne diseases caused
by Pythium and Phytophthora. Formulated as a WP
(Terrazole), etridiazole may be used in a preventive
program for control of Pythium blight in turf and of
damping-off in ornamentals. It is also formulated in
mixture with pentachloronitrobenzene (quintozene) as
Terraclor Super X, which is applied in-furrow to cotton
for control of seedling diseases (Rhizoctonia, Pythium,
Fusarium). Application rates in cotton are equivalent to 1
to 1.5 and 0.26 to 0.39 kg ai ha?1 for PCNB and etridiazole,
respectively.
Uses
Different sources of media describe the Uses of 2593-15-9 differently. You can refer to the following data:
1. Etridiazole is a contact fungicide with protective and curative
action that is used to control Phytophthora and Pythium spp. in ornamentals,
cotton, peanuts, vegetables and turf.
2. 5-Ethoxy-3-(trichloromethyl)-1,2,4-thiadiazole is a fungicide that can be incorporated into the soil or compost to control Phytophthora spp. and Pythium spp. Useful in cannabis testing kits as a component of pesticide mixes (P698235).
Definition
ChEBI: A member of the class of thiadiazoles that is 1,2,4-thiadiazole which is substituted at positions 3 and 5 by trichloromethyl and ethoxy groups, respectively. A fungicide, it has been used particularly for the control of Phytophthora and
Agricultural Uses
Fungicide: Etridiazole is a fungicide used in some countries
as a seed treatment on barley, beans, corn, cotton, peanuts,
peas, sorghum, soybeans, safflower, and wheat. It is
also used on cotton for in-furrow application at planting,
on ornamental plants and shrubs by horticultural nurseries,
on non-bearing citrus and non-bearing coffee, and
for golf course fairways, tees and greens. Some states
hold Special Local Need registrations for use on tobacco
transplants.

Metabolic pathway
The main metabolic pathways of etridiazole in mammals are dechlorination
of the 3-trichloromethyl moiety followed by oxidation yielding
the carboxylic acid derivative or glutathione-mediated dechlorination.
Catabolism of the glutathione conjugate via the mercapturic acid pathway
affords the cysteine conjugate that is in turn N-acetylated to give the
mercapturic acid.
Shipping
UN2810 Toxic liquids, organic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required. Military driver shall be given full and
complete information regarding shipment and conditions in
case of emergency. AR 50-6 deals specifically with the
shipment of chemical agents. Shipments of agent will be
escorted in accordance with AR 740-32.
Degradation
The DT50 for hydrolysis of etridiazole is 103 days (25 °C, pH 6). The compound
was hardly decomposed at 20 °C by sunlight over 7 days (PM).
The rate of hydrolysis of etridiazole increased with pH and temperature
and the only product was 3-carboxy-5-ethoxy-1,2,4-thiadiazole (2) (EPA,
1980).
Toxicity evaluation
Etridiazole has low acute toxicity toward mammals
(rat: oral LD50 1,100 mg/kg; rabbit: dermal LD50 >
5,000 mg/kg; rat: inhalation LC50 (4 h) 5.7 mg/L), and
birds (mallard duck: LC50 1,650 mg/kg; bobwhite quail:
LC50 > 5,000 mg/kg). It is also nonteratogenic. However,
chronic administration to rats was associated with an
increased incidence of thyroid follicular cell tumors, and
etridiazole (Terrazole) is included by the EPA in its list of
Group B2 carcinogens.The only noteworthy ecotoxicological effect concerns
the aquatic toxicity of the combination product, Terraclor
Super X, which is highly toxic towards both fish and
Daphnia. However, this can be attributed more to the
PCNB component (bluegill sunfish: LC50 0.1 mg/L, EPA
designation “highly toxic”) than to etridiazole (LC50
3.27 mg/L, “moderately toxic”). Risk in practice would be mitigated by the use pattern of the product involving
in-furrow soil application.
Waste Disposal
Incineration would be an
effective disposal procedure where permitted. If an efficient
incinerator is not available, the product should be mixed
with large amounts of combustible material and contact
with the smoke should be avoided. In accordance with
40CFR165, follow recommendations for the disposal of
pesticides and pesticide containers
Check Digit Verification of cas no
The CAS Registry Mumber 2593-15-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,9 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2593-15:
(6*2)+(5*5)+(4*9)+(3*3)+(2*1)+(1*5)=89
89 % 10 = 9
So 2593-15-9 is a valid CAS Registry Number.
