Can Celsius be used to kill Virginia buttonweed when temperatures are above 90 degrees?

Answer:

Celsius can be used for Virginia buttonweed, but it is best to apply when temperatures are below 85 degress in order to avoid damaging your turf.  If your temperatures reach above 90 during the day, apply in the morning or evening when it is cooler.
