Task: Summarization
Input (English): I have been plagued by white flies for over a year. Neither chemical nor natural treatment has gotten rid of them completely. I decided to try this as it's made by a respected international brand & I thought a systemic product might work. A week after the first application there was no reduction in infestation but by the second week I started to notice less & less of the little vermin. By the time I was ready to do a third application there was not even one white fly or any other insect on any of my roses or any other shrub. I had even used it on potted plants which were also infested & it worked on everything. Remember, the product is systemic and is absorbed gradually into the plant so you will not see an immediate improvement but it works wonderfully.  Also if like me, you don't always remember to spray regularly or get the underneaths of the leaves, then something which you can sprinkle at the base of the plant every 6-8 weeks is certainly a lot easier to use.
Output (English): Excellent Product
