Flint Fongicide Bayer CropScience

Flint

Overview

Flint® is a broad-spectrum systemic fungicide with long-lasting preventative protection against important diseases in pome fruit, grapes and cherries. It works by inhibiting spore germination and mycelial growth, and provides extended preventive protection by protecting the leaf surface, penetrating plant tissue and redistributing through vapour action. 

A recent sampling program of scab-infected apple leaves from orchards across Ontario has revealed the presence of QoI-resistant apple scab. Bayer is advising apple growers in Ontario not to use Flint for control of apple scab. Apple growers outside of Ontario should tank mix Flint with a compatible registered contact fungicide (EBDC) to provide two modes of action to control apple scab.
