Agrothrin Dusting Powder Another fantastic product to harness the insect controlling qualities of Pyrethrins, Agrothrin is an extremely effective dusting powder that we have found to particularly effective against Thrip larvae, Fungus Gnats, Fungus Gnat larvae, Root aphid, Silverbacks and Springtails. It's unique application method (dusting rather than spray) means that it lasts longer in a grow room situation and can be used to dust the tops of growing media to provide an effective barrier against many pests. Highly recommended and excellent value. IMPORTANT NOTE: We cannot send/supply Agrothrin to any UK offshore destination including Isle of Wight, Isle of Man, Scilly Isles, Scottish Islands (Western Isles, Orkney, Shetland, etc) Northern Ireland, Republic of Ireland and Channel Isles. This is due to the International Maritime Dangerous Goods (IMDG) code.
