Is this the following sentence correct? use

"I would rather she were writing about this topic now."

Note my corrections above. To start with "Is this the correct use ...", you'd need to follow it with "of", then the word, phrase, or grammar point you're hoping to demonstrate. The actual sentence would follow.

The sentence you've written is grammatically possible. Whether it's the "correct" sentence for the context you have in mind is impossible to say because you've given us no context.
