| Popis: | Crack and crevice treatment was affected by nozzle type and nozzle height. Highest mortality of the German cockroach resulted when using crack and crevice nozzles inserted 4 mm inside the crack. As nozzle height increased, cockroach mortality decreased. There was no significant difference (5% level) between crack width and cockroach mortality. The fan nozzle was the least effective treatment. |
