Zusammenfassung:The persistence of granulosis virus infectivity in soil has been investigated. Virus applied to soil was extracted at different time up to 1 year after the original application and the amount of virus was determined using bioassays. In this way the content of infective capsules remained was determined. It was shown that about 99% of the original virus infectivity was lost during 1 year. Together with other investigations this result indicates that leaching, passive lateral movements and degradation accounts for the main part of the loss.
