The contact and translaminar acting acaricide Borneo has a Specific Off Label Approval (SOLA) for use on protected strawberries and is active against the two main species of spider mite - the Two-spotted Spider Mite (Tetranychus urticae) and the Fruit Tree Spider Mite (Panonychus ulmi).
Integrated crop management specialist for Fargro Neil Helyer said: "We are so impressed with Borneo that we are hoping to apply for a SOLA in raspberries, where spider mites can cause severe damage to canes."
He added: "In protected strawberries Borneo is applied just before first picking, keeping within its three-day harvest interval but benefiting from its four to six weeks protection.
"With a normal picking period of six to eight weeks, Borneo starts off the control programme, which can then be augmented by the introduction of predators, Phytoseiulus persimilis, which gives good curative activity of spider mites, or Amblyseius californicus, which can work with the higher temperatures.
Growers need a specific licence for the latter, but Borneo can be used quite safely with either predators."
Growers can also use the product, which contains etoxazole, on protected tomato, aubergine and ornamental crops.
