    i work for a lawn care company and have noticed good results by using a split application with pre-em. my question is, how many times and at what intervals can i apply these to bermuda with out doing damage. i applied aqua-caps in mid Jan. and a fert.+pre-em mix in march. are these types good or are ther better pre-ems out there

    Check with your county extension service for timing. We have good ones here in TX.

    I applied Barricade (prodiamine) at 1/2 half of the max rate in Sept and then again in Dec of last year, and still have had very little breakthrough despite the heavy rains.

    thanks for the info..what about the spring time? can you use barricade then, or is it a fall pre-em? also, can you apply it ti st. augustine? do weeds or soil build up a "tolerance" if you use the same pre-ems year after year?
