Abstract

In Iran, potato cyst nematode (Globodera rostochiensis) jeopardizes the traditionally high yields of potatoes in Hamadan Province in the west of Iran. Biofumigation is an eco-friendly method for integrated management of plant parasitic nematodes. In the laboratory, water extracts of water cress, fenugreek and dill similarly reduced viability of second stage juveniles after 3 h of exposure, and decreased hatching of encysted eggs to less than 1%. Pre-treatment and combined tests similarly decreased hatch. The nematicidal efficiency of top green manure of Lepidium sativum on the survival of nematode was tested on a susceptible cv in microplots. The weights of biofumigated plants increased. Anti-hatching properties of water cress applied as a biofumigant reduced hatch by average of 56%. Reproduction rates were lowered to below one, and final populations of cysts and their egg contents were reduced by nearly 60% in treated soil. Biofumigation at a 1% amendment rate was sufficient to bring about these results, which were comparable with those achieved with 2 and 3% rates. Nematicidal isothiocyanates released after incorporating glucosinolate-containing brassica plants are fully biodegradable and less toxic than their synthetic equivalents, and their use is considered a safer alternative to soil fumigants such as methyl bromide.
