Bayer Systemic Working on Aphids—Use Sparingly

Ted reports success with Bayer systemic on aphids: new growth on 'Red Dragon' VFT, S. flava, and S. leucophylla is normal. Asks if he should continue per label.

Use Judiciously

Jacob Farin: "Since the product is systemic, you'll should use it judiciously. At our nursery, we use it once or twice a year on the same batch of plants. It's very rare that a batch of plants will need a third application in a 12-month period. If you see new growth developing the tell-tale signs of aphid damage, definitely spray again according to the manufacturer's instruction."
