PHI


The Pest Management Regulatory Agency (PMRA) sets and monitors the Maximum Residue Levels (MRLs) of pesticides registered in Canada for application to food crops. Dosages and practices recommended in the Guide should not result in residues on fruit at harvest exceeding these MRLs. Similar spray-residue laws are in effect in other countries which import our fruit. In some countries the MRL values differ from Canadian tolerances.

Growers are warned that fruit having residue levels in excess of allowable limits may be seized under the federal Food and Drug Act. Furthermore, fruit with too high a pesticide residue indicates excessive  dosages were used or that the minimum days between last spray and harvest (pre-harvest Interval or PHI) for pesticides as recommended in this guide. Application of unregistered pesticides can lead to prosecution under the Pest Control Products Act.

Visible spray residue will prevent the marketing of fruit even if the pesticide residue is below the MRL.

The following tables list the minimum number of days between the last spray and harvest for pesticides recommended in the Guide.

NOTE: Pre-harvest intervals are subject to change. Always follow the crop PHI values shown on the label.
