Weed Killer That Will Not Harm Beneficial Nematodes

Question From: M. Flippin - TEXAS
Q: I have been over run by weeds. I applied beneficial nematodes for insect control last year. Can I use mama on my weeds And not harm my little friends? Or what product do you suggest? Thanks

A: I am not familiar with mama.. Natria Lawn Weed Killer may be a good choice although you should contact the manufacturer regarding the effects of this pesticide on soil dwellers. I would also Google Reviews on the product. The following paragraph is part of a review on Amazon:
 
If you want to find out more about the active chemical, use Google to find "Iron HEDTA and weeds." The University of California Weed Science group and the Dept. of Horticulture at Cornell have published some results of their preliminary research
