Fungicidal carboxamides
View Patent ↗Compounds of Formula I are disclosed which are useful as fungicides wherein X is —O—, —CH(R 11 )—or ═C(R 11 )—; R 1 is H or C 1 –C 2 alkyl; R 2 is H; C 1 –C 6 alkyl; C 3 –C 6 cycloalkyl; or phenyl optionally substituted with halogen, cyano, C 1 –C 2 alkyl or C 1 –C 2 alkoxy; and R 3 –R 11 are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula I and a method for controlling plant diseases caused by fungal plant pathogens which involves applying an effective amount of a compound of Formula I.
1. A compound selected from the formula I,
wherein
X is —CH(R 11 );
R 1 is H;
R 2 is H;
R 6 is C 2 –C 6 allyl, C 2 –C 6 alkenyl, C 2 –C 6 alkynyl or C 3 –C 6 cycloalkyl each optionally substituted with halogen or CN;
R 7 is H or halogen;
R 8 is H, R 9 is H or halogen; and
R 11 is H.
2. A fungicidal composition comprising a fungicidally effective amount of a compound of claim 1 and at least one of a surfactant, a solid diluent or a liquid diluent.
3. A method for controlling plant diseases caused by fungal plant pathogens comprising adding to the plant or a portion thereof, or to the plant seed or seedling, a fungicidally effective amount of a compound of claim 1 .
4. A composition comprising a compound having the formula,
wherein
R 1 is H;
R 2 is H;
R 6 is C 2 –C 6 alkyl, C 2 –C 6 alkenyl, C 2 –C 6 , alkynyl or C 3 –C 6 cycloalkyl each optionally substituted with halogen or CN;
R 7 is H or halogen;
R 8 is H, R 9 is H or halogen; and
R 11 is H;
and at least one of a surfactant, a solid diluent or a liquid diluent.
5. The composition of claim 4 wherein the composition is in a form selected from the group consisting of liquid, powder, emollient, aerosol, and granules.
6. A method of treating a plant wherein the method comprises contacting at least a portion of a plant with an effective amount of the composition of claim 5 .
