Indaziflam is a preemergent herbicide especially for grass control in tree and bush crops.

History

In 1991, the Japanese company Idemitsu Kosan filed a patent to 2-amino 6-fluoroalkyl triazine derivatives as herbicides.[3] One of these compounds was subsequently given the ISO common name triaziflam but had limited success as a commercial herbicide.[4][5] Bayer scientists subsequently investigated this area of chemistry and identified indaziflam as having superior properties, which they patented and developed under the code number BCS-AA10717.[6][7] The compound was first registered for use in the USA in 2010.[8][9]

Mechanism of action

Indaziflam is an inhibitor of cellulose biosynthesis. This mechanism of action was theorized to be responsible for indaziflam's effect in 2009[7] and proven in 2014.[10] The cellulose biosynthesis inhibitors (CBIs) are identified as Class 29 by the Weed Science Society of America/Herbicide Resistance Action Committee.[11][12]

Resistance

(As of March 2021) there are no resistant populations known[13] and none for the broader CBI class (discounting quinclorac).[11][14][15][16][17]

Brand names

Indaziflam composes all or part of the a.i. of several herbicides from Bayer Environmental Science (now owned by Cinven, aka Envu, per Bayer's and Envu's websites), [18] [19] including Rejuvra,[20] the Esplanade[21] line (sometimes mixed with diquat dibromide and glyphosate isopropylamine),[22] Marengo,[23][24] Specticle,[25][24] and Bayer CropScience (the inventor of the ingredient), like Alion.[26]

Uses

Indaziflam is approved in the United States for hops, Rubus spp., Coffea spp., bushberries, tropical crops, drupes/stone fruit, and tree nuts.[27] It is used as a preemergent.[28][27]
