Solufeed managing director Dick Holden is concerned that many bedding plant growers may be unaware that the forthcoming temporary ban on the use of neonicotinoids will directly affect them.
The European Commission has confirmed that restrictions on the use of three neonicotinoid pesticides will come into force on December 1.
One of these, imidacloprid, marketed by Solufeed under the brand name Couraze, has been widely used in compost to combat common pests such as sciarid and aphid.
Holden said: "Under the new regulations, growers only have until November 30th to use existing stocks. After that date, they will have to comply with the new label text which stipulates that plants grown in media treated with this product may not be put outside until after they have finished flowering.
"The new regulation thereby effectively rules out the use of imidacloprid for flowering bedding plants for up to two years - after which the restrictions are due to be reviewed."
Solufeed are not able to offer an effective substitute at present.
Non flowering crops and those not put outside when in flower are exempt from the EU restrictions.
