The one you linked to uses Imidacloprid as the active systemic ingredient. I use Bayer Advanced 3-in-1 as a liquid that is diluted; same systemic ingredient. There is also Lily Miller granular systemic, active ingredient "acephate" but it has fertilizer in it. I used the Bayer Advanced last year on my semp trays in the greenhouse, they were terribly infested with "something". The iris growers also use Imidacloprid for thrips in Japanese iris. It worked great for me. Do any of these products sound familiar to you? There are so many on the market it can be hard to choose until you find the one best for your needs.
