Will Farmers Pay to Enlist Pimps?

Low rates allow for a larger percentage of the
population to be resistant. Free wheat is correct.
Low rates (below label rate) increase the rate of
resistance..

In my opinion; anyone who thinks the can kill 100% of any weed poulation with any chemical (or combination) is fooling themselves. As sawfly correctly observed; there is always the one in a million (or billion or whatever) resistant oddball.

And by definition that oddball will escape and in all likelihood never, ever be possible to eradicate. And it will get to even the farms where someone even has fooled themselves into believing they are immune to any or every chemically resistant threat.
All one can do is slow the spread of the inevitable.
At a seminar on this very topic, more than a decade ago ( or maybe closer to two decades); I well remember the analogy to firing a gun. If you have 10 bullets you can fire them in a burst; or spread them over a much longer period of time, by alternating with different groups of chemicals with different modes of action. But you're still only going to get about ten shots with that particular chemical group before there is a noticable lack of control.

And your neighbors chemical use and your seed supply contamination, and cropping patterns suscepable to certain weed growth problems will all impact if you even get your ten shots off without the resistance coming prematurely.

You can't kill every weed; and the resistant ones will develop further resistance in about the same time period ( or maybe less).
Accept that fact.

oneoff,

Except... we can kill weeds through mechanical means as well. The combination IS deadly. The combination is effective and efficient.

There is no such thing as a super weed.
There are only super slick media campaigns
with a super promotion purpose.

"Why would R-up be banned soon? "

I would assume what hedgehog was eluding to when
he also mentioned DDT is once a proper assessment
of the side effects is undertaken.

[dave4441]

That makes even less sense.

[furrowtickler]

Retards = weed resistance. Agree with some of above, it's not rocket science it's called common sense, that's it in a nut shell.... end of story. Use the same under arm deoderant for 30 years and see what happens - circus clowns caused the problem not producers who can actualy think out side the retailers office. We have no issues on our dirt yet but may b/c of other's stupidity.

[hedgehog]

farmers who own their dirt will look after it, as always. its the corporates who cause the probs.

[oneoff]

Populations of anything grow to fill their niches that they are adapted and suited too. Example; a wild oat plant (whether chemically resistant to one orm ore or all chemical groups) could give a rats ass as long as its environment allows wild oats to grow and prosper. Once you're dealing with resistance; it does not go away; and no one should think that in the next 10 applications of a different chemical group you will not have lost another effective control for yet a another similar mode of action chemicals.
Read the "book" that is attached to every chemical container. They talk about CONTROL; and not nearly 100% either. You can't eradicate weeds without much more drastic harm to living plants and animals.


And while tillage doesn't select for resistance to the extent of chemicals; it too only can control weeds.

[dave4441]

Any gentics, with selection pressure applied to them, can evolve in a very short period of time. Survival of the fittest. Early seeding selects for earlier weed germination. Tillage also selects. Chemical weed control will cause resistance. It is why i find it impossible to believe in religion's stories of the origin of man.
