Thrips on Laurustinus

At the recent meeting of the New Zealand Institute of Horticulture a letter was received from Mr. Charles Haines, Wellington, urging the elimination of the common Laurustinus (Viburnum Tinus) and tho substitution of the giant variety (Viburnum i.inus lucidum). After a good deal of discussion, ths following resolution (Mrs. Knox Gil mer-H. J. Boole) was carried unani inously:— “In view oi the ravages of thrips in sects, which have been specially severe in gardens during the past season, as indicated by tho number of representa tions made to the institute, this execu tivo resolves that all nurserymen be cir cularised, drawing attention to the fact that the principal source of infection is the common Laurustinus (Viburnum Tinus), thence passing on to more valuable plants; and recommending that, in tho circumstances, they discontinue raising and distributing this species, substituting therefor the giant variety (Viburnum Tinus lucidum), which is lelatively immune from attack.

‘ ‘ This recommendation is mado on the grounds that, if the common species is not further distributed and is eliminated where already planted, tho control of thrips in respect of the more valuable plants would bo materially simplified. ’ ’ It was resolved further (H. J. PooleMrs. Ivnox Gilmer); ‘ ‘ That a copy of the resolution and tho circular should be forwarded to tho Department of Agriculture and also to the New Zealand Horticultural Trades’ Association, requesting that this effort should, be supplemented as far as possible.”
