除草剂可能会破坏湖泊中某些稀有植物的种群。
Soybeans and corn are not sown together in the same filed; nevertheless, most farmers are reluctant to use the herbicide on their corn.大豆和玉米不是在同一块地里播种的;然而,大多数农民不愿意在他们的玉米上使用除草剂。
One very effective herbicide is safe for corn, but soybeans are damaged even by the herbicide's residue, which remains in the soil more than a year after the herbicide is applied.某种非常有效的除草剂对玉米来说是安全的,但即使是除草剂的残留物也会对大豆造成损害,该残留物在施用除草剂一年多后仍残留在土壤中。
