I need to KILL this!

Looks like some type of ryegrass, it's scattered over my yard. My lawn is tall fescue, had I known that tall fescue grew in patches that itself looks like crabgrass I would have chosen a better grass but alas I am stuck with it for now, How do I kill this weed/ryegrass off? from the information I have gathered it is a perennial so it will only live once but the seeds will fall off and regrow next year, If I were to pick all of these tops off would it die off next year? also read that it is very intolerant to heat and being in central California we can hit 110F pretty easily in summer so maybe a combo of picking all the seed tops and the heat will kill it off? I can tell you ortho weed-b-gon max didn't do anything but fertilize it.

It's a grass. Weed-b-gone doesn't kill grass.
Maybe someone here could suggest something that selectively kills rye and doesn't hurt fescue, but I don't know of anything other than heat.
Rather than picking the seed tops, you could let it grow tall, and then mow it very low as it gets really hot. That will stress it the most. Especially if you cut it with a dull blade (maybe a string trimmer. . . )

Perennial means that it stays year after year. Annuals die each year, and the seeds grow new plants. Ryegrass comes in both annual and perennial varieties, BUT if you have a warm enough winter, some annual varieties may not die.

Took it to a nursery and they said it was some type of fescue that went to seed, in case anyone comes across this and wonders what it is.

You could just mow it with the rest of the grass.

You may also want to check out the definition of perennial.
