map depicting the percent of average precipitation received across Ontario in June 2021

Regrowth rates of hay fields following a cut and pastures following a grazing event is dependent on rainfall. Areas that received below-average rainfall may experience slower regrowth.

Producers looking to buy or sell hay are encouraged to check out the new and improved Ontario Hay Listings website

Southwest

  • According to AAFC, most of the area south of Highway 7 received average rainfall for June, while north of the highway was below average. Parts of Essex and Chatham-Kent had over 150% of average precipitation for the month. Niagara was drier than average, and the Bruce Peninsula received less than 40% of normal rainfall for June.
  • Alfalfa weevil pressure was high on second cut. The hot, dry weather allowed the weevils to get ahead of the pathogenic fungus that usually controls the weevil population.
  • Potato leafhopper populations were building, and alfalfa growers were encouraged to scout. “Hopperburn” is often confused with insufficient water.
  • Second cut began on dairy farms the last week of June.

Central and East

  • According to AAFC, the central and eastern regions of the province received below average precipitation for June. Rainfall across the region was patchy.
  • Alfalfa weevil pressure was high on second cut. The hot, dry weather allowed the weevils to get ahead of the pathogenic fungus that usually controls the weevil population.
  • Potato leafhopper populations were building, and alfalfa growers were encouraged to scout. “Hopperburn” is often confused with insufficient water.
  • A frost in early June caused some superficial damage to established alfalfa.
  • Second cut began on dairy farms the last week of June.

Northeast

  • According to AAFC, the northeast had below average rainfall for June, ranging from 40-85% of normal.
  • Frost in early June is not unheard of, but additional frost events later in the month reduced grass yields in Cochrane and Temiskaming Districts.

Northwest

  • According to AAFC, Thunder Bay District had average rainfall for June, while the rest of the region received below-average precipitation.
