Excellent 
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.

Hi there. Is the Agrothrin effective for root aphids that hides within roots under the ground? Since it is dusted onto the soil, the root aphids might not get in contact to it? Do you have other recommended product to kill root aphids?
Hi
For root aphids inparticular we recommend using live predators such as nematodes which you can find here.
Hope this helps

We would recommend using the Pyrethrum 5 EC spray on your plants, & the Agrothrin Thrip Dust on the top of your growing media.
