Effects of silicon and plant defence inducers on sugarcane yield parameters, Eldana saccharina Walker (Lepidoptera: Pyralidae) and Fulmekiola serrata Kobus (Thysanoptera: Thripidae) † [Full subscriber]

Substantial evidence now exists for the beneficial effects of silicon (Si) fertilisation on sugarcane yield and in suppressing stalk borer infestation. Pot trials were used to examine the interactive effects of soil supplied Si and foliar sprays of the plant defence inducers, cis-jasmone (JA) and Bion® (a synthetic analogue of salicylic acid) on plant resistance to the borer Eldana saccharina Walker (Lepidoptera: Pyralidae) and thrips, Fulmekiola serrata Kobus (Thysanoptera: Thripidae), as well as on yield and cane quality components. Silicon reduced borer survival and damage, but had no effect on thrips numbers. Jasmonic acid and Bion had no consistent effects…
