The city says the cankerworm control program was not completed over the weekend due to poor weather.
Weather permitting, spraying will continue Tuesday night starting at 9:30 p.m.
Crews will be in the Jefferson and Seven Oaks neighbourhoods and in Kildonan Park.
Spraying will not happen if there is significant rainfall or winds stronger than 20 kmph, says city officials.
Winnipeggers can register for a buffer zone by calling 311 or visiting the city's website.
