P-21 The Effect of Clay on the Inhibitory Effect of Mustrad Seed Meal on Velvetleaf Seedling Growth
Department

Abstract
Mustard seed meal has been studied as a biofumigant in suppressing weed growth in farming systems lacking herbicide usage. MSM contains glucosinolates that hydrolyzes into volatile isothiocyanates which have herbicidal properties. Previous studies have shown that MSM in elevated sand content was highly effective in suppressing the germination of velvetleaf weed seeds, and that it decreased in an increased clay/silt content. Based on this, it was postulated that clay may inhibit MSM efficacy by preventing isothiocyanateaction. Two different types of clay were tested at various concentrations to measure the reduced inhibition of seed germination by MSM. Low concentrations of both types of clay didn’t inhibit the weed suppressive properties of MSM.
