The Herbicide Resistance Diagnostic Lab conducts herbicide resistance diagnostic testing on a weed population per one herbicide basis.  The chart below outlines the how herbicides are grouped for a given price depending on the diagnostic test that will be conducted.  It is important to note that the cost to diagnose resistances is far lower than the cost to re-treat and continue to use ineffective herbicides.  Herbicide resistance diagnosis will save you time and money.

Diagnostic Assay Herbicides Commonly Tested Price per herbicide or sequenced gene section$ Time to complete#
Group I Rapid Diagnostic Assay foramsulfuron, trifloxysulfuron, metsulfuron, halosulfuron, imazaquin, imazethapyr, penoxsulam, florasulam, chloransulam, bispyribac, pyrithiobac, imazapicm fluazifop, fenoxaprop, diclofop, cyhalofop, and similar modes of action $650 2 to 4 weeks
Group II Rapid Diagnostic Assay prodiamine, pendimethalin, trifluralin, oryzalin, oxadiazon, indaziflam $630 2 to 4 weeks
Group III Rapid Diagnostic Assay atrazine, simazine, diuron, amicarbazone, and similar modes of action $605 1 to 3 weeks
Traditional Diagnostic Assay All other herbicides such as carfentrazone, sulfentrazone, 2,4-D, dicamba, triclopyr, S-metolachlor, and others $1,040 4 to 8 weeks (whole plants) or 4 to 6 months (derivied from seed)
Genes Sequenced to Confirm Exact Mutations
Gene sequencing ALS Gene, CT-domain of ACCase Gene, regions of alpha and beta tubulin, region of psbA gene, region surrounding Pro-106 mutation conferring glyphosate resistance* $1,415 1 to 6weeks
*Genes are sequenced based on herbicide of interest.
#Time to complete each is dependent on the herbicide and weed desired tested.  Times may vary from the period listed.  Contact the lab for exact time periods.
$Prices listed are for a single weed population (see sampling guidelines) and a single herbicide.  Assay results will be released following payment.
