Abstract

Fungicides have been shown to cause long term changes in the growth and metabolism of treated plants leading to higher biomass and yield, apart from inducing stress tolerance. Fungicidal compounds belong to strobilurins and triazoles namely trifloxistrobin and tebuconazole as combinations were applied in groundnut to understand mechanism by which it alters the plant metabolism leading to higher productivity. Foliar application of Nativo 75WP, a formulation consisting of trifloxistrobin and tebuconazole @ 250 g ha-1, 300 g ha-1, 350 g ha-1 and Carbendazim @ 500 g ha-1 at 35 and 50 days after sowing was attempted in a field experiment on groundnut. The result indicated that Nativo 75WP significantly improved the root length and total dry matter accumulation at different stages of growth. Among the different concentrations, application of Nativo 75WP @ 300g ha-1 increased the number of pod and pegs, peg to pod ratio, 100 kernel weight and shelling percent.
