It's winter/spring in Texas with temps ranging from 20-80 in the same 48 hours. Winter time weeds are out and the soil is 55 degrees at 4" down.
In general, it is fine to mix a pre-emergent herbicide like Prodiamine 65 WDG and a post-emergent like Trimec as long as neither product label prohibits this mixture. Be sure you use the correct rates for each product. We also recommend a small jar test for compatability before mixing a larger tank. You also will need to activate the Prodiamine with irrigation or rainfall after at least 24 hours but within 14 days of the application, per the product label.
