Indaziflam
(Beyond Pesticides, May 23, 2022) 'The climate change-induced increase in wildfire frequency and intensity has lent new urgency to efforts to manage so-called “invasive” plants. Unfortunately, the herbicide-based approach favored by many is both counterproductive and hazardous.
Use of the herbicide indaziflam is an example of the ineffectiveness of management based on herbicides. While indaziflam is considered a “selective” herbicide, it actually kills and prevents germination of a wide range of broad-leaved plants and grasses and comes close to being a soil sterilant. The action on seedlings is long-lasting, thus inhibiting the growth and establishment of a resilient plant community that is resistant to invasion. Given its persistence and nonselective action and the extent of the damage it causes to native soil seed banks and plant biodiversity, indaziflam could contribute to the eventual ecological collapse of ecosystems where it’s applied, similar to the cascading impacts of the systemic insecticides, fipronil and the neonicotinoids on animals.'
'Indaziflam’s health effects are also significant. The nervous system is the major target for toxicity in mammals.'
SNAP Comment: As of 11 June 2022, there are 7 indaziflam labels registered by the PMRA. Indaziflam was promoted and used for 10 years with an incomplete (“conditional”) registration in the US. It was likely the same in Canada as we still allowed conditional registrations at that time. Several labels are registered for use in orchards and containers.
