In vitro activity of some glucosinolates and their reaction products toward a population of the nematode Heterodera schachtii

Abstract

An in vitro study has conducted of the nematocidal effect of some glucosinolates and the products of their myrosinase-mediated enzymatic hydrolysis on second-stage juveniles of the sugar beet cyst nematode Heterodera schachtii. The glucosinolates tested were purified from the seeds or from plant organs of some crucifers cited as hosts of the nematode: Brassica napus, Lepidium sativum, Brassica rapa, Brassica carinata, Raphanus sativus, and Sinapis alba. The glucosinolates were dissolved concentrations in both the absence and presence of the enzyme myrosinase, and their nematocidal effect in time on second-stage juveniles was then determined
