Systemic insecticides: spray or pour?
Posted: Sat Aug 06, 2022 10:31 pm
I have access to a few systemic insectides where I am at (Belgium, Europe) such as:
Sanium concentrate (Protect Garden) - 25 g/l flupiradifurone - up to 8 weeks of protection
Multisect (KB) - 5g/l acetamiprid - up to 3/4 weeks of protection
Perfekthion (BASF) - 400 g/l Dimethoat
All of these insecticides prescribe a foliar application and there are no instructions for a soil drench. Only on the website of Uhlig Kakteen do they make mention of a soil drench for KB Multisect: 60ml of Multisect per liter of water instead of 10ml per liter of water for a foliar application.
Is there a reason they only prescribe a foliar application? From a consumer point of view, pouring potted plants can happen in a more controlled (and safer) way. The reason I'm also asking is, can I repurpose the above insectides for soil drenches?
I'm not a big fan of systemic insecticides, but don't always have the time or the means to apply 'alternative' measures. I've never had a major outbreak of any kind, due to good plant hygiene. Over the years I've also learned good cultivation practices (thanks to the forum!) and feel my plants are healthier and happier than when I first started.
Any feedback is welcome and I suppose contacting the aforementioned companies would also help.
