POSTERITY® Fungicide label expanded via Minor Use Program to help manage Fusarium internal rot on Greenhouse Peppers and Botrytis grey mould on Greenhouse Lettuce

Written by Josh Mosiondz, Minor Use Coordinator, OMAFRA

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for POSTERITY® Fungicide for suppression of Fusarium internal rot on greenhouse pepper and Botrytis grey mould on greenhouse lettuce in Canada. POSTERITY® Fungicide was already labeled for disease control on a wide range of crops in Canada. These minor use proposals were submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) as a joint project with the United States Department of Agriculture (USDA) IR-4 project 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 disease management decisions within a robust integrated disease management program and should consult the complete label before using POSTERITY® Fungicide.

Crop(s)TargetRate (L of product / ha)Application InformationPHI (days)
Greenhouse PeppersSuppression of Fusarium internal rot   (Fusarium spp.)0.625Apply no more than 2 foliar and no more than 2 drench applications for a maximum of 3 applications or total of 375 g ai/ha per crop cycle. Optimal control is achieved with a program of multiple applications. Apply in sufficient water volume to obtain thorough coverage.  For foliar application a minimum spray volume of 150 L/ha is recommended. Apply when plants are flowering or when conditions are favourable for infection. DO NOT apply to peppers intended for transplant out to fields.0
Greenhouse LettuceSuppression of Botrytis grey mould   (Botrytis cinerea)1.0Apply in sufficient water volume to obtain thorough coverage. For foliar application a minimum spray volume of 150 L/ha is recommended. Increase water volumes as the canopy density increases. Apply when conditions are favourable for infection. DO NOT apply to lettuce intended for transplant out to fields0

TOXIC to aquatic organisms and non-target terrestrial plants. Observe spray buffer zones specified under DIRECTIONS FOR USE. Pydiflumetofen is persistent and may carryover. It is recommended that this product not be used in areas treated with any products containing pydiflumetofen during the previous season. This product demonstrates the properties and characteristics associated with chemicals detected in ground water. The use of POSTERITY Fungicide in areas where soils are permeable, particularly where the water table is shallow, may result in ground water contamination. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative filter strip between the treated area and the edge of the water body

Follow all other precautions, restrictions, and directions for use on the POSTERITY® Fungicide label carefully.
