I have heard that Glyphosate is the key chemical and in all wee killers, but in small amounts. Therefore making the weed killer no very affective. Can Glyphosate be purchased undiluted? If so where ca I purchase some? as the conventional weed killers don't have muc effect

1) This doesn't belong in rec.gardens.orchids... but since traffic has been so heavy... 2) Read the effing label. Many broad spectrum weed killers are dilute glyphosate. Many are diluted 2,4-d for broadleaf control. And there are many more fun things for crabgrass control. 3) Where you purchase some depends on where you are. I tend to go to local ag supply stores and buy a large jug of concentrate.
All the farmers are using genetically engineered roundup tolerant crops and regularly spraying roundup on the fields to keep the weeds at bay. Over the past decade or two the genetically engineered crops have changed the way farmers grow crops. Thing is super weeds are starting to show up which are also roundup tolerant. This time of year the super weeds really show up and I have enjoyed checking out fields as I drive around. Looks like we have at least 3 or 4 different types of super weeds around here. Some fields have real problems while other fields are showing no weeds. This is going to be a real problem soon if a Roundup II does not show up soon.

I like to think that if I was a farmer, and had a batch of those resistant weeds, I would do what ever it took to keep them from going to seed. If necessary, using a flame thrower and sacrificing part of the crop to kill them. Cheaper to do that rather than have them infest the whole field.
