Nematicidal compounds penetrans

Fungal metabolites represent a vast repository of materials and compounds with evolved biological activity, including nematicidal effect. Some of these compounds can be used directly or as templates for nematicides. Plants such as a burdok Arctium lappa L), a carrot Daucus carota L), a radish Rapharm sativus L.) and so on are parasitized by dte nematode, Pratylenckus penetrans, and show necrosis and successively breakdown of root cortex cells. 

Table 2. Nematicidal activities of compounds 1-4 and aspyrone against Prafylenchus penetrans.

Nematicidal activities of 1-4 against the root-lesion nematode Pratylenchm penetrans were shown Table 3. Compounds 1-4 promoted nematicidal activity proportional to its concentration from 1 mg/L to 1000 mg/L and nematicidal activities by 83%, 100%, 67%, and 99% at concentrations of 1000 mg/L, respectively. In addition, 1, 2 md 4 have more effective nematicidal activities than that of aspyrone.
