David McCallum said: The product works William but not quite in the class of MB.........the key is proper application. Have seen it work in the sod industry and on golf fairways both with mixed results. Again a good applicator (or application) is key.
I think David hit the nail on the head here. Basamid is pretty darn good, but it is not as good as methyl bromide. With Basamid the application at the highest rate and proper follow-up irrigation is crucial. I do not think either one claims to completely eradicate everything. I do not know if Basamid controls sting nematodes. That might be a question for the manufacturer's rep.
I used both Basamid and methyl bromide, but it was not a fair comparison. We have an 18-hole par 71 and a 9-hole par 30. We used methyl bromide on the par 71, but we also removed the top 3" and rototilled in 4" of sand. We used Basamid on the par 30 and did a no-till.
My recommendation is to use methy bromide if you have the money. If you don't, Basamid is a fair alternative, but pay close attention to the application instructions.
