David from Santa Rosa, Ca writes

Mixing ratio and best time to apply Bensumec 4LF Herbicide for Poa Annua in Northern CA tall Fescue grass?

Answer:

Bensumec 4LF Herbicide should be applied in the spring and in the fall right before soil temperatures drop below 70 degrees. If the germination of poa annual, crabgrass and other annual weeds extends into late summer and early fall, a 2nd application of Bensumec 4LF at the specified rates should be applied 4-5 months after the initial application. 

Refer to page 2 of the product label for single and split application rates.
