Description and Uses

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.

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.
