I've done a root drench and also sprayed the hedges at the 1.5oz to 100 gallon rate about 10 days ago and then another round a couple days ago and it seems that the whitefly numbers are actually increasing. There are clouds of whiteflies above the shrubs where previously there were not. The root drench was at a higher rate as recommended on the label. I'm concerned that this product does not work as indicated.
Please be advised that it can take 8 weeks a systemic product to be translocated throughout the plant. If you are trying to treat an active infestation, doing a foliar spray with a product like Talstar P is the better option because it will help to kill anything that you spray directly and will leave a residual of up to 30 days. Please be advised that the instructions on the product label should always be followed. Mixing a product stronger or applying more often than stated does not make it any stronger or help it to be absorbed quicker.
