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 کاملImproved methods of hatching Heterodera schachtii larvae for screening chemicals.
The rate of hatching of Heterodera schachtii larvae was greatly increased by placing cysts in sieves enclosed by small disposable cups. An apparatus that permitted rapid storage of second-stage larvae at 10 C prolonged the viability of the larvae.
متن کاملThe Potato Eelworm Hatching Factor 4. SOLANUM NIGRUM AS A SOURCE OF THE POTATO EELWORM HATCHING FACTOR BY P. B. RUSSELL, A. R. TODD AND W. S. WARING
It has been known for some time that the root excretion of several species of Solanum stimulates the hatching of larvae from the cysts of the potato eelworm, Heterodera ro8tochien8i8 (Franklin, 1940). The isolation ofthe active principle in root excretion and the investigation of its chemical nature was first attempted, using the leachings from potato plants (Hurst, 1935, 1937), but the method ...

متن کاملEffects of selected carbamate and organophosphate nematicides on hatching and emergence of Heterodera schachtii.
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 ...
