Plant NutritionCrown®
Scotts introduces breakthrough technology in systemic insecticides for the professional grower. Crown is a systemic insecticide that works both on contact with target pests and systemically through root and leaf uptake. Crown features new chemistry designed for faster, more effective control of sucking pests and fungus gnat. In fungus gnat trials, Crown stood head and shoulders above the rest, outperforming other formulations.
Key features and benefits
- Crown is totally systemic through root and leaf uptake, also acting on contact with target pests
- 100% knockdown of many target pests within 50 minutes, outperforming competitor products1. Crown is fast and long lasting
- Crown provides effective control at low rates of application
- Crown is relatively soft on many benificial insects2 e.g. 300 x less toxic via contact and 2000 x less toxic via oral than its closer competitor on honey bees3.

Case Study
Taking care of business
As Australia's largest grower dealing exclusively with pelargoniums, Gary Dale of Geranium Cottage has spent twenty-five years refining his
growing techniques to simultaneously improve plant quality and lift volume of production – without increasing costs. The key? "Better science, more advanced chemicals," says Gary.
Pelargonium is a genus comprising around two hundred species of plants that, in various parts of the world, are commonly known as geraniums. The extensive range of pelargoniums at Geranium Cottage is continuously being updated as new varieties are brought in from Europe.
Geranium Cottage pelargoniums are sold mainly through Bunnings as well as wholesalers in New South Wales and Gary's own retail outlet. A such, the need to balance volume and margin is an ever-present challenge. “To mass produce successfully it’s no longer acceptable to see a third of your plants get chucked out,” says Gary. “Ninety-nine percent have got to be saleable.”
