“…Dichlobenil and isoxaben, two other CBI herbicides, are labeled at approximately 10 and 40 times greater herbicide concentrations than indaziflam (73 and 102 g AI ha −1 ) . In addition, indaziflam has several other chemical properties that result in enhanced residual weed control: lipophilicity (log K ow = 2.8), low water solubility (2.8 mg L −1 ), no photodegredation and a moderate positive correlation between sorption and soil organic matter . Therefore, lethal indaziflam concentrations are biologically available at the soil surface with sufficient moisture for plant uptake, resulting in extended weed control.…”

“…Indaziflam provides broad‐spectrum pre‐emergence control of several annual grasses and broadleaf weeds . Indaziflam is lipophilic (log K ow = 2.8) and has low water solubility (2.8 mg L −1 ), which could partially explain its increased residual soil activity compared with other commonly recommended herbicides . Indaziflam is applied at low use rates and recommended at 73 and 102 g AI ha −1 for residual winter annual grass control in open spaces and natural areas.…”

INDAZIFLAM: A NEW CELLULOSE BIOSYNTHESIS INHIBITING HERBICIDE PROVIDES LONG-TERM CONTROL OF INVASIVE WINTER ANNUAL GRASSESInvasive winter annual grasses such as downy brome (Bromus tectorum L.) are a threat to native ecosystems throughout the US. These invasive grasses exploit moisture and nutrients throughout the fall and early spring before native plants break dormancy. This results in decreased native species abundance and development of monotypic stands. Short-term downy brome management has been shown to be effective; however, the soil seed reserve has often been overlooked although it's the mechanism responsible for rapid re-establishment. While glyphosate, imazapic, and rimsulfuron are herbicides commonly recommended to control invasive, annual grasses, their performance is inconsistent, and they can injure desirable perennial grasses. Indaziflam is a recently registered cellulose-biosynthesis inhibiting herbicide, providing broad spectrum control of annual grass and broadleaf weeds. Indaziflam (Esplanade ® , Bayer CropScience) is a cellulose biosynthesis inhibiting (CBI) herbicide that is a unique mode of action for resistance management and has broad spectrum activity at low application rates.

“…Zorner et al (1984) observed that initially nondormant For soil-applied herbicides to be effective, fall or very early spring pre-planting applications are required. Kochia can germinate and emerge under very low temperature and low-moisture requirements and, therefore, identifying herbicides that can be activated and effective with low-moisture conditions are critical (Sebastian et al 2017). The first flush of kochia is usually very dense and can appear rapidly in late February and very early March in the central Great Plains.…”

Timing of weed emergence and seed persistence in the soil influence the ability to implement timely and effective control practices. Emergence patterns and seed persistence of kochia populations were monitored in 2010 and 2011 at sites in Kansas, Colorado, Wyoming, Nebraska, and South Dakota. Weekly observations of emergence were initiated in March and continued until no new emergence occurred. Seed was harvested from each site, placed into 100-seed mesh packets, and buried at depths of 0, 2.5, and 10 cm in fall of 2010 and 2011. Packets were exhumed at 6-mo intervals over 2 yr. Viability of exhumed seeds was evaluated. Nonlinear mixed-effects Weibull models were fit to cumulative emergence (%) across growing degree days (GDD) and to viable seed (%) across burial time to describe their fixed and random effects across site-years. Final emergence densities varied among site-years and ranged from as few as 4 to almost 380,000 seedlings m − 2 . Across 11 site-years in Kansas, cumulative GDD needed for 10% emergence were 168, while across 6 site-years in Wyoming and Nebraska, only 90 GDD were needed; on the calendar, this date shifted from early to late March. The majority (>95%) of kochia seed did not persist for more than 2 yr. Remaining seed viability was generally >80% when seeds were exhumed within 6 mo after burial in March, and declined to <5% by October of the first year after burial. Burial did not appear to increase or decrease seed viability over time but placed seed in a position from which seedling emergence would not be possible. High seedling emergence that occurs very early in the spring emphasizes the need for fall or early spring PRE weed control such as tillage, herbicides, and cover crops, while continued emergence into midsummer emphasizes the need for extended periods of kochia management. Nomenclature: Kochia, Kochia scoparia (L.) Schrad. KCHSC.

“…5 IND is lipophilic and has low water solubility (2.8 mg•L -1 ), which could explain its increased residual soil activity compared to other herbicides. 6,7 Moreover, its positive correlation between sorption and organic matter contents indicates that its long persistence of residual activity in soil requires that it be used with caution, because of its carryover potential. 3 IND dissipates in the environment primarily through degradation and leaching.…”

In the present work, the chemical reactivity of indaziflam N-[(1R,2S)-2,3-dihydro-2,6-dimethyl-1H-inden-1-yl]-6-[(1R)-1-16 fluoroethyl]-1,3,5-triazine-2,4-diamine so called indaziflam (IND) and its metabolites: triazine indanone (ITI), indaziflam carboxylic acid (ICA) and fluoroethyldiaminotriazine (FDAT) was analyzed. The calculations were performed at the X/6-311++G(2d,2p) (where X=B3LYP, M06, M06L and wB97XD) level of theory, in the aqueous phase. The results indicate that ITI is the more reactive followed by ICA, IND and FDAT. The distribution of the active sites was determined evaluating the Fukui function employing the frozen core and finite difference approximations. For electrophilic attacks, IND shows the more reactive zone on the benzene ring, ITI and ICA on the nitrogen atom in the central section and FDAT on its nitrogen atoms. The more nucleophilic sites for IND are observed on the carbon atoms of triazine, on the carbonyl group for ITI, on the carboxylic group for ICA, and on the nitrogen atoms of triazine for FDAT. For free radical attacks case, the more reactive sites for IND are on the benzene and triazine rings, on the carbonyl group, nitrogen of the central section, and nitrogen atoms of triazine, for ITI, carboxylic group for ICA, and on the nitrogen atoms of triazine ring for FDAT.
