Effect of quizalofop and fenoxaprop on nutrient and antinutrient contents during seed development of mung bean (Vigna radiate L.)

Abstract

In an effort to examine the impact of two herbicides viz. Quizalofop, and Fenoxaprop on the changes in contents of total phenol, sugar, starch and protein including trypsin inhibitory activity during the period of seed development of mung bean, a field experiment was conducted with application of these herbicides at their recommended field dose (RFD) and double the recommended field dose (dRFD) on 20 and 40 days after sowing of mung bean along with untreated control. The chemical analyses indicated that the untreated control followed by quizalofop treatment at RFD registered higher sugar, starch, protein and phenol content. On the other hand, diminished TIA level and enhanced antioxidant activity under DPPH assay were observed with untreated control followed by quizalofop treatment at dRFD. The rank order of different herbicide treatments in terms of antioxidant activity measured under different system was not similar. Based on the result, application of quizalofop at RFD can safely be recommended in mung bean cultivation.
