bearphant Posted January 3, 2013 Report Share Posted January 3, 2013 (edited) Hi guys, in the year just passed i've had a bad infestation of mealybug on my sarrs, and although i have treated them with an imidacloprid based insecticide (Provado Plus) and now i see no signs of living pests, I would like an opinion about an insecticide with the same active principle but to be mixed in the substrate during repottings. INTERCEPT - Suscon (Scotts) Composition: Imidacloprid 5.3%. Broad-spectrum systemic insecticide. Dose: against mealybug and whiteflies, 50gr/100lt of substrate. At the recommended dose the product remains active for 12 months. Has someone ever used it (or something similar) with sarrs and/or other CPs? Could it be dangerous? Does it give the desired results? Tips? Thank you all and Happy Holidays :) Edited January 3, 2013 by bearphant Quote Link to comment Share on other sites More sharing options...

ada Posted January 6, 2013 Report Share Posted January 6, 2013 I can see where your coming from with the insecticide lasting a full 12 months,but i think it would be very hard to get 50g mixed thoroughly in 100 litres of compost. I fear you would end up with some having no insecticide in and the first bit it touches with too much,which in a large concentration may be detrimental to your plants. It is much easier to use provado in the soil drench form,where you can get a more even application.Even if you do have to reapply during the season for full protection or the pests re-occur. ada Quote Link to comment Share on other sites More sharing options...
billynomates666 Posted January 7, 2013 Report Share Posted January 7, 2013 Hi Bearphant I'm with ada, you do run the risk of an incomplete or non uniform mix which may cause problems, I also find a Provado drench most effective and it is easy to apply in minutes, also with it being systemic it is absorbed by the leaves and is active for weeks. If you did mix it with the substrate you would have to repeat the operation eventually so I dont see too many advantages. I just spray everything early spring mid summer and early autumn if necessary as precautionary measures. I dont try to make it any more dificult for myself than necessary, being a bit on the lazy side. Cheers Steve Quote Link to comment Share on other sites More sharing options...
bearphant Posted January 7, 2013 Author Report Share Posted January 7, 2013 (edited) ok, thanks for your suggestions... so i'd better drop the idea :/ Edited January 7, 2013 by bearphant Quote Link to comment Share on other sites More sharing options...
bearphant Posted January 8, 2013 Author Report Share Posted January 8, 2013 wait a minute... but if i dilute the insecticide in the water i use for hydrating the substrate...? It should mix quite uniformly!?! Quote Link to comment Share on other sites More sharing options...
ada Posted January 8, 2013 Report Share Posted January 8, 2013 How much water do you need to hydrate 100 litres of compost? and isn't that just the same as using pravado as a soil drench? ada Quote Link to comment Share on other sites More sharing options...
bearphant Posted January 8, 2013 Author Report Share Posted January 8, 2013 I fear that i don't fully understand the meaning of "soil drench"... do you mean a full immersion of the plant in a provado plus solution? or what? sorry for my poor knowledge of the language!

gardenofeden Posted January 8, 2013 Report Share Posted January 8, 2013 Soil drench: you pour the solution onto the compost. Quote Link to comment Share on other sites More sharing options...
bearphant Posted January 8, 2013 Author Report Share Posted January 8, 2013 Thank you :) Yes, it's more or less the same thing, but my provado plus is a spray, and it doesn't seem to be openable, so it would be hard to pour it on the soil...

gardenofeden Posted January 8, 2013 Report Share Posted January 8, 2013 You can buy provado as a concentrate. It is also much cheaper than pre-mixed. Quote Link to comment Share on other sites More sharing options...
bearphant Posted January 8, 2013 Author Report Share Posted January 8, 2013 Oh, i didn't find it, and i don't know if it's sold here in Italy... Anyway i could pour the intercept onto the compost as you do with provado plus (doing some calculation on the concentration), couldn't i? It seems quite the same thing... How do you act?
