The Liaison User Guide is available through the Horticultural Development Company (HDC) website and has been developed with the Food & Environment Research Agency to help growers keep track of the rules for pesticide use.
HDC nursery stock panel chairman Nick Dunn said it was vital that growers offer feedback on the service in order for it to be as good as it can be.
He explained: "We are using it here on our growing side (at Frank P Matthews) and we are quite confident it should prove very useful. It's a complex area but I'm confident this will be a lot better for growers. Although it's up to date, we are very keen to hear from growers if it's not useable."
Fargro also consulted on the tool's development and managing director Dr Paul Sopp said it would be "extremely useful".
"It gives growers a real-time way of checking current approvals," he added. "Until now it had been a bit of a minefield with the changes to the long-term approvals, so this will be really useful.
"We have been going through a lot of changes on long-term approvals for ornamental growers. The situation was uncertain and this gives growers access to real-time changes so they can check whether products are legal or not."
The tool allows users to select a crop and, knowing the pesticide type they need, to search all products currently approved for use on-label or off-label through SOLAs and also see all those products that can still legally be used under the long-term arrangements.
Clicking on links in the list provides details on application rates, intervals, handling, disposal, safety precautions, environmental warnings and tank mix compatibility.
Additional features include the ability to sort pesticides by modes of action using the Fungicide, Herbicide & Insecticide Resistance Action Committee's activity codes.
The system can also display products no longer approved, as well as information on control agents not requiring registration.
