The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Lalstop G64 WG Biological Fungicide on select greenhouse crops.

This fungicide (previously known as Prestop WG) is approved for suppression of soil-borne and foliar diseases on greenhouse-grown eggplant, Asian water spinach, strawberries and indoor-grown cannabis in Canada.

Containing Gliocladium catenulatum strain J1446, Lalstop G64 WG Biological Fungicide was already labeled for use on several greenhouse-grown vegetables, herbs and ornamentals in Canada for management of these diseases.

These minor use projects were submitted by Ontario as a result of minor use priorities established by growers and extension personnel.

The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated pest management program and should consult the complete label before using Lalstop G64 WG Biological Fungicide.

Growers are encouraged to follow precautions, restrictions and directions for use on the Lalstop G64 WG Biological Fungicide label carefully.
