چکیده
Ethoprop, oxamyl, PP 156, fenamiphos, carbofuran , AC 64,475, Bunema M, CG 12223, aldicarb, aldicarbsulfoxide, and aldicarbsulfone were tested for their effects on hatching and emergence of larvae from cysts of Heterodera schachtii. The oxime carbamates and carbofuran inhibited hatching , but this response was reversed by removing the chemical treatment . Inhibition of hatching by Bunema M and all organophosphates tested was irreversible .

Effects of Selected Nematicides on Hatching of Heterodera schachtii.
Aldicarb, carbofuran, fensulfothion, and phenamiphos were tested in concentrations of 1-100 mug/ml for their effects on hatching of Heterodera schachtii. Exposure of cysts to 1 mug aldicarb or carbofuran/ml stimulated hatch whereas phenamiphos and, to a lesser degree, fensulfothion inhibited hatch. Addition of aldicarb to sugarbeet root diffusate or 4 mM zinc chloride suppressed activities of t...
متن کاملA Comparison of the Hatching of Juveniles from Cysts of Heterodera schachtii and H. trifolii.
The effects of root diffusates of selected plants within the families Chenopodiaceae and Cruciferae and the hatching agent zinc chloride were tested for their effects on hatching and emergence of juveniles from cysts of Heterodera schachtii and a race of H. trifolii parasitic on Chenopodaceae and Cruciferae in The Netherlands. Although all diffusates strongly stimulated hatching of juveniles of...
متن کاملPlant-parasitic Nematode Acetylcholinesterase Inhibition by Carbamate and Organophosphate Nematicides.
The sensitivity of acetylcholinesterases (ACHE) isolated from the plant-parasitic nematodes Meloidogyne arenaria, M. incognita, and Heterodera glycines and the free-living nematode Caenorhabditis elegans to carbamate and organophosphate nematicides was examined. The AChE from plant-parasitic nematode species were more sensitive to carbamate inhibitors than was AChE from C. elegans, but response...

متن کاملEvaluation of Biocontrol Activity of Rhizobacteria from Beta vulgaris against Heterodera schachtii.
One hundred fifty rhizobacteria isolated from roots of Swiss chard grown in a soil suppressive to the sugar beet cyst nematode, Heterodera schachtii, were tested for their influence on the nematode's ability to hatch and infect roots. Two screening systems were used that focused on the ability of bacteria to inhibit either nematode hatching or root infection. Most of the bacterial strains reduc...
