Abstract
Compounds are prepared which correspond to the formula ##STR1## wherein Y represents trichloromethyl, dichloromethyl or dichlorofluoromethyl; X represents chloro, bromo or fluoro and n represents an integer of 1 or 2. These compounds and compositions containing them have been found to be useful as agronomic fungicides, especially useful and valuable for the control of soil-borne plant disease organisms which attack the roots of plants.
Claims32
A compound corresponding to the formula:
- ##STR15## wherein Y represents trichloromethyl, dichloromethyl or dichlorofluoromethyl;
- X represents chloro, bromo, or fluoro and n represents an integer of 1 or 2.
A fungicidal composition comprising a fungicidally effective amount of a compound corresponding to the formula:
- ##STR16## wherein Y represents trichloromethyl, dichloromethyl or dichlorofluoromethyl;
- X represents chloro, bromo or fluoro and n represents an integer of 1 or 2, in intimate admixture with an inert adjuvant therefor.
A method for protecting plants from plant fungal disease organisms which attack the plant root system which comprises contacting plants, plant parts or their habitat with a non-phytotoxic, plant protecting amount of a plant protectant corresponding to the formula:
- ##STR17## wherein Y represents trichloromethyl, dichloromethyl or dichlorofluoromethyl;
- x represents chloro, bromo or fluoro and n represents an integer of 1 or 2, in intimate admixture with an inert adjuvant therefor.
The method as defined in claim 20 wherein the plants, plant parts or habitat are contacted with the plant protector prior to the plants being attacked by plant root disease organisms.
