Summary The effect of several commercial disinfectants on the infectivity of infectious laryngotracheitis virus was studied. Benzalkonium chlorides did not cause any detectable inactivation of the virus when their concentration was less than 0.001%, but at concentrations greater than 0.01% no surviving virus was detected. At 0.00015% 2,4‐dichloro‐meta‐xylenol did not detectably inactivate virus, while no virus survived in the presence of 0.01% of the compound. In the presence of 1% skim milk, ten times as much disinfectant was needed to inactivate the same amount of virus. An anthelmintic and an anti‐histomonad had no detectable effect on virus infectivity at concentrations of 0.32% and 0.025% respectively. The significance of the findings in relation to vaccination of poultry against infectious laryngotracheitis via drinking water is discussed.
