Abstract

Indaziflam is an alkylazine herbicide that controls annual grasses by inhibiting cellulose biosynthesis. Compared with other PRE herbicides like prodiamine, indaziflam has a longer half-life in soil (> 150 d), which may allow for greater flexibility with application timing. Research was conducted in 2010 in Tennessee and Georgia evaluating smooth crabgrass control efficacy with indaziflam applied at early PRE, PRE, and early POST timings on the basis of soil temperature. Regardless of application timing, all rates of indaziflam (35, 52.5, and 70 g ai ha−1) controlled smooth crabgrass 89 to 100%. Prodiamine at 840 g ai ha−1 applied PRE provided ≥ 99% smooth crabgrass control on all rating dates. Smooth crabgrass plant counts were significantly correlated (r = −0.961; p < 0.0001) with visual ratings of smooth crabgrass control at the end of the study. Application flexibility with indaziflam may benefit turf managers in scheduling herbicide applications for smooth crabgrass control in Tennessee and Georgia.

El indaziflam es un herbicida del grupo químico alkilazine, que controla gramíneas anuales inhibiendo la biosíntesis de la celulosa. Comparado con otros herbicidas preemergentes (PRE) como prodiamina, indaziflam tiene una vida media más larga en el suelo (>150 días), lo cual quizás permita una mayor flexibilidad con el tiempo de aplicación. Una investigación se realizó en 2010 en Tennessee (TN) y Georgia (GA) para evaluar la eficacia de control de Digitaria ischaemum con indaziflam aplicado en preemergencia temprana (EPRE), PRE y postemergencia temprana (EPOST), basados en la temperatura del suelo. Indistintamente del tiempo de aplicación, todas las dosis de indaziflam (35, 52.5 y 70 g ia ha−1) controlaron Digitaria ischaemum de 89 a 100%. Prodiamina a 840 g ia ha−1 en etapa PRE proporcionó ≥99% de control en dicha maleza, en todas las fechas de evaluación. El conteo de plantas de Digitaria ischaemum estuvo significativamente correlacionado (r = −0.961; p < 0.0001) con dosis visuales de control de maleza, al final del estudio. La flexibilidad de aplicación con indaziflam, podría beneficiar a manejadores de céspedes a calendarizar las aplicaciones del herbicida para controlar Digitaria ischaemum en TN y GA.
