The latest provincial crop report says some crops are showing signs of serious heat stress in southern Saskatchewan.
Provincial crops analyst Shannon Friesen says a few areas received rain this week, but many parts of the south need rain for parched fields.
Friesen says many southern and central areas have had less than 100 millimeters since the start of April.
Other sources of crop damage this week include hail, local flooding, wind and insects like alfalfa weevils, painted lady caterpillars and wheat midge.
Haying is at 24 percent with yields down as much as 50 percent because of dry weather.
