I have asked several farmers in the midwest how much they spend for
*seed and herbicides*. Here is what they told me.
RR program = $43.97
Conventional Program = $47.04
Seed $17.00/ bag x 1.5 = 25.50
Tech feee $6.50/bag x 1.5 = 9.75
1 qt Roundup burndown @$32/gal = $8.00
1 qt roundup in season = $8.00
Total cost = $51.25
Non roundup ready
Seed (bin run) $6.50/bu x 75 lb = $8.13
1 qt roundup burndown = $8.00
1.5 qt Squadron @ $37.00/ gal = $13.88
Possible 2nd treatment of Squadron= $13.88
Total cost = $30.01 - $43.89
Seed: $21.00/unit & 1.2-1.5 unit/acre rate =$31.50
Tech Fee: $6.50/unit & 1.2-1.5 unit/acre = $9.75
Roundup Burndown: 1 quart =$8.00
Roundup Ultra In-Crop: 1 quart =$8.00
Other farmer comments:
* '97 I had some RR beans that I got by with a total of 1.5 pints of RU!
There were NO weeds early to burn down, so I put
the "burndown" on at about the 3rd trifoliate, then no more was needed.
*I wouldn't say that "anybody" can get by with 3pints total RU, in a
season. "Some" might get by "some" of the time, maybe.
First rule of farming, Things never work exactly the same, consistantly!
*chemical cost would depend on whether you are no till or not...working
the ground would let you get by with a quart in mid
season followed by a pint or one and half pint in late season for
*we are no till, and spray half rate Canopy-Command mix in March,
followed by one and half pints to one quart of RU
depending on what is there in mid season...this gives 100 per cent weed
control...something we never accomplished with any
So there you have it. Nothing more then a random sampling of bean
farmers on the internet. I think the the average costs for seed and
herbicides of a RR program is nearly the same as a conventional program.
And the costs are more likely in the $50 range then $68.77
