Abstract:

Pesticides are predominantly used to manage rice yellow stem borer (YSB), Scirpophaga incertulas Walker, killing both pests and natural enemies. Used as biofertilizers, phytostimulators, rhizoremediators and biopesticides in crop production, lactic acid bacteria (LAB) are likely to reduce the impact of pesticides on natural enemies, if compatible. In this study, an LAB formulation made from milk-powder, cane jaggery and egg was evaluated in combination with flubendiamide against S. incertulas and its egg parasitoids (Tetrastichus schoenobii Ferriere and Telenomus sp.) in replicated field trials and in laboratory. The results indicated that the LAB formulation significantly enhanced not only the efficacy of flubendiamide 20 WG @ 25 or 50 g a.i. ha-1, probably from its adjuvant action, but also the extent of parasitization by the parasitoids, which is discussed.
