Abstract:

Heterodera schachtii is the most important nematode of sugar beet worldwide. Application of organic matter can reduce populations of plant-parasitic nematodes. In this study, the inhibitory effects of creeping thistle, tall sisymbrium, liquorice, narrow-leaf plantain, wild lettuce, castor bean, French marigold, cornflower, wild safflower and arugula on sugar beet cv. Sharif and H. schachtii were investigated in two microplot experiments. The first experiment was conducted in pasteurized mixed field soil and river sand, and the second in field soil, both with an initial population of 4200 eggs/plant. Also, the effects of the treatments on nematode egg hatching and root penetration were studied in a glasshouse experiment. The results showed that adding plant powders to pasteurized soil had no significant effect on the infected sugar beet growth indices. However, except marigold, the other treatments caused a relative increase in taproot weight of 5% to 241% compared to the control. Cornflower, wild lettuce and wild safflower increased taproot weight more than twofold compared to the control. Moreover, creeping thistle, castor bean and plantain caused a relative decrease in nematode final population and reproduction factor. In field soil, castor bean, marigold, wild lettuce, cornflower and sisymbrium increased taproot weight by at least twofold, and arugula increased sugar content by 1.2-fold. The treatments had no significant effect on the nematode indices. Plantain and wild lettuce caused a relative decrease in the nematode reproduction factor. In glasshouse experiment, wild lettuce caused the greatest reduction in egg hatching and safflower reduced nematode penetration into the roots.
