The cyst nematodes of the genera Heterodera (HET) and Globodera (GLO) are among most damaging obligate plant parasitic (PPNs) that parasitize cereals, rice, potatoes soybean. In absence resistant crops, soil fumigation pesticides provides a good strategy for population control. However, synthetic nematicides can cause negative environmental public health impacts feared to lead development resis...

Sterols from free sterol and steryl ester fractions from Heterodera zeae and from total lipids of Zea mays roots were analyzed by gas-liquid chromatography (GLC) and by GLC-mass spectrometry. The major free sterols of H. zeae were 24-ethylcholesterol (54.4% of total free sterol), 24-ethylcholesta-5,22-dien-3beta-ol (13.3%), 24-methylcholesterol (12.5%), and cholesterol (7.2%). The same four ste...

Phylogenetic analysis of new ribosomal DNA (rDNA) data for Heterodera mediterranea, H. hordecalis, H. carotae, and H. fici from Italy and H. ciceri from Syria, along with published data for other species, showed high bootstrap support for the following relationships: (((((H. carotae H. cruciferae) H. goettingiana) (((H. trifolii H. ciceri) H. mediterranea) ((H. avenae H. latipons) H. fici))) (C...

An approach based on image analysis that enables rapid collection and analysis of nematode size and shape during growth is reported. This technique has been applied to assess Meloidogyne incognita and Globodera pallida during their development over 35 and 42 days, respectively, on transgenic tomato roots expressing the wild-type rice cystatin Oc-I or an engineered variant, Oc-IAD86. Morphometri...

Abstract Ethanedinitrile is a chemical soil fumigant with promising efficacy against several key pests including weeds, nematodes, and soil-borne pathogens. The of 12 concentrations ethanedinitrile, ranging from 8.7 to 1,751 mg kg − 1 soil, control seeds tubers five weed species ( Cyperus esculentus, C. rotundus, Malva parviflora, Portulaca oleracea , Stellaria media ), two nematode Globodera r...
