Weed Management With Pro-Herbicides Benzobicylon And Florpyrauxifen-Benzyl In Louisiana Rice Production, William Bradley Greer
LSU Doctoral Dissertations
Field studies were conducted in 2020 and 2021 to evaluate benzobicyclon tolerance to 71 weedy rice accessions collected from Louisiana and southern Arkansas. Benzobicyclon was applied at 373 g ai ha-1 as a postflood application on 3- to 4-leaf rice. At 28 DAT, less than 15% control was observed on 70% of the accessions and 80% or better control was observed on 3% of accessions. Inconsistent weedy rice control can be attributed to the presence or absence of a functional HIS1 allele. The functional HIS1 allele was present in 96% of accessions when treated with benzobicyclon control was less …

A study was conducted at the LSU AgCenter H. Rouse Caffey Rice Research Station (RRS) to evaluate benzobicyclon herbicide application timing on water-seeded rice. Benzobicyclon was applied at seven different timings, at 246 g ai ha-1 in a water-seeded rice production system. Benzobicyclon controlled ducksalad above 90% when applied into the pinpoint flood. Barnyardgrass control was greater than 90% from applications made on pegging rice and immediately following pinpoint flood establishment. At 49 days after treatment (DAT), yellow nutsedge control exceeded 90% following benzobicyclon treatment with a pegging rice or pinpoint flood timing. Ducksalad control was greater than 90% following …
