Selectivity index of indaziflam to sugarcane cv. IACSP95-5000 in two soil textures

Selectivity index is a way of assessing the discrimination of herbicide to a given crop by observing its effects on the crop and the weeds. The aim was to obtain the selectivity index of indaziflam herbicide to sugarcane cultivar IACSP95-5000 as a function of five weed species in two soils textures. The experiment was carried out in a greenhouse at Piracicaba, São Paulo, Brazil. The treatments consisted of indaziflam doses (0; 12.5; 25; 50; 100; 200; 400; 800 and 1,600 g of the active ingredient (ai) ha-1), applied in pre-emergence of the sugarcane and of the weeds Urochloa decumbens, Urochloa plantaginea, Digitaria horizontalis, Panicum maximum and Rottboellia cochinchinensis. In sandy loam soil, a 100% control for all weeds was provided at 25 g ai ha-1. In clay soil, for D. horizontalis the 90% reduction in total dry mass (ED90) was obtained at 25 g ai ha-1, for R. cochinchinensis at 193 g ai ha-1, for U. plantaginea at 152 g ai ha-1, for P. maximum at 124 g ai ha-1, and for U. decumbens at 94 g ai ha-1. Indaziflam was selective to IACSP95-5000 in both soils, with 10% of reduction in dry mass (ED10) at 137 g ai ha-1 for soil with a sandy loam texture and 353 g ai ha-1 for clay soil. The selectivity index was higher than 1 for all weeds in clay soil. It was not possible to obtain the selectivity index for sandy loam soil due to species susceptibility to the herbicide.

The aim was to obtain the selectivity index of indaziflam herbicide to sugarcane cultivar IACSP95-5000 as a function of five weed species in two soils textures. The experiment was carried out in a greenhouse at Piracicaba, São Paulo, Brazil. The treatments consisted of indaziflam doses (0; 12.5; 25; 50; 100; 200; 400; 800 and 1,600 g of the active ingredient (ai) ha-1), applied in pre-emergence of the sugarcane and of the weeds Urochloa decumbens, Urochloa plantaginea, Digitaria horizontalis, Panicum maximum and Rottboellia cochinchinensis. In sandy loam soil, a 100% control for all weeds was provided at 25 g ai ha-1. In clay soil, for D. horizontalis the 90% reduction in total dry mass (ED90) was obtained at 25 g ai ha-1, for R. cochinchinensis at 193 g ai ha-1, for U. plantaginea at 152 g ai ha-1, for P. maximum at 124 g ai ha-1, and for U. decumbens at 94 g ai ha-1. Indaziflam was selective to IACSP95-5000 in both soils, with 10% of reduction in dry mass (ED10) at 137 g ai ha-1 for soil with a sandy loam texture and 353 g ai ha-1 for clay soil. The selectivity index was higher than 1 for all weeds in clay soil. It was not possible to obtain the selectivity index for sandy loam soil due to species susceptibility to the herbicide.

El índice de selectividad es una forma de evaluar el efecto selectivo de un herbicida para un cultivo determinado mediante la observación de sus efectos sobre el cultivo y las malezas. El objetivo fue obtener el índice de selectividad del herbicida indaziflam en el cultivo de caña de azúcar IACSP95-5000 en función de cinco malezas en dos texturas de suelo diferentes. El experimento se realizó en un invernadero en Piracicaba, São Paulo, Brasil. Los tratamientos consistieron en dosis de indaziflam (0; 12,5; 25; 50; 100; 200; 400; 800 y 1,600 g ai ha-1), aplicadas en pre-emergencia de la caña de azúcar y de las malezas Urochloa decumbens, Urochloa plantaginea, Digitaria horizontalis, Panicum maximum y Rottboellia cochinchinensis. En suelo franco arenoso, 25 g de ia ha-1 proporcionaron un control del 100% para todas las malezas. En suelo arcilloso, para D. horizontalis la reducción del 90% en la masa seca total (ED90) se obtuvo a 25 g ai ha-1, para R. cochinchinensis a 193 g ai ha-1, para U. plantaginea a 152 g ai ha-1, para P. maximum a 124 g ia ha-1, y para U. decumbens a 94 g ia ha-1. Indaziflam fue selectivo para IACSP95-5000 caña de azúcar en ambos suelos, con 10% de reducción de masa seca (ED10) a 137 g ia ha-1 para suelo con textura franco arenosa y 353 g ia ha-1 para suelo arcilloso. El índice de selectividad fue superior a 1 para todas las malezas en suelo arcilloso. No fue posible obtener el índice de selectividad para suelos franco arenosos debido a la susceptibilidad de las malezas al herbicida.
