Abstract
Official abstract text for this publication.
At present, a large number of herbicidal compositions have been developed and used. However, weeds to be controlled include a lot of kinds, and the emergence thereof extends over a long period of time. Therefore, the appearance of a herbicidal composition having a broad weed spectrum and having a high activity and a long residual effect is desired. The present invention relates to a synergistic herbicidal composition comprising (A) at least one member selected from the group consisting of flazasulfuron, nicosulfuron, and their salts and (B) pyroxasulfone or its salt. According to the synergistic herbicidal composition of the present invention, a herbicidal composition having a broad weed spectrum and having a high activity and a long residual effect can be provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling an undesirable plant or inhibiting the growth thereof, comprising applying a synergistic herbicidal composition comprising (A) flazasulfuron or its salt and (B) pyroxasulfone or its salt, wherein a mixing ratio of (A) to (B) is from 8:1 to 1:1 in terms of a (A):(B) weight ratio, wherein the undesirable plant is black nightshade or wild oat. 2. The method according to claim 1 , wherein a mixing ratio of (A) to (B) is from 4:1 to 2:1 in terms of a (A):(B) weight ratio. 3. A method of controlling an undesirable plant or inhibiting the growth thereof, comprising applying synergistic herbicidally effective amounts of (A) flazasulfuron or its salt and (B) pyroxasulfone or its salt to an undesirable plant or a place where an undesirable plant grows, wherein (A) is applied in an amount of from 100 to 150 g/ha, and (B) is applied in an amount of from 12.5 to 150 g/ha, wherein the undesirable plant is black nightshade or wild oat. 4. The method according to claim 3 , wherein (A) is applied in an amount of 100 g/ha; and (B) is applied in an amount of from 25 to 50 g/ha.
