Abstract
The invention relates to a composition comprising (a) 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione, or an agriculturally acceptable salt or metal complex thereof; and (b) N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-( 4′-fluoro-oxycetanilide); and their use as herbicides.
Claims18
A method for controlling the growth of weeds at a locus which comprises applying to said locus a herbicidally effective amount of:
- (a) 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione or an agriculturally acceptable salt or metal complex thereof, and
- (b) N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide) having the formula (II):
- 3
The method according to any one of the preceding claims using an application rate of from 5 g to 512 g per hectare of 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione and from 50 g to 5000 g per hectare of N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide).
The method according to any one of the preceding claims using an application rate from 20 g to 200 g per hectare of 2-(2′-nitro-methylsulfonylbenzoyl)1,3—1,3-cyclohexanedione and from 80 to 875 g per hectare of N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide).
The method according to any one of the preceding claims using an application rate of from 25 to 150 g per hectare of 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione and from 300 to 500 g per hectare of N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide).
The method according to any one of the preceding claims by pre-emergence application.
A herbicidal composition comprising:
- (a) 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione or an agriculturally acceptable salt or metal complex thereof;
- and
- (b) N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide);
- in association with a herbicidally acceptable diluent or carrier and/or surface active agent.
A product comprising a herbicidally effective amount of:
- (a) 2-(2′-nitro-4′-methylsulfonylbenzoyl)-1,3-cyclohexanedione or an agriculturally acceptable salt or metal complex thereof, and
- (b) N-isopropyl-(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-4-(4′-fluoro-oxyacetanilide);
- as a combined preparation for simultaneous, separate or sequential use in controlling the growth of weeds at a locus.
