Books gave wrong pesticide advice

Gardening Which? highlights error

Some titles in an acclaimed series of gardening books have been giving out the wrong information on pesticides, Gardening Which? can reveal.

More than 45 million copies of the Expert series by Dr D.G. Hessayon have been sold to gardeners across the globe.

But it’s emerged that 13 titles in the popular 22-book series may contain out-of-date information about pesticides.

Gardening Which? was alerted to the problem by eagle-eyed member George Campbell, who spotted that the 2006 edition of The Fruit Expert recommended products that hadn’t been on the market for years.


Gardening Which? subsequently found that at least seven products in The Fruit Expert were either no longer available or approved for amateur use in the UK.

The magazine contacted Dr Hessayon who explained that 13 books in the series were reprints – rather than new editions – and therefore could contain out-of-date pesticide information.

Dr Hessayon said that revised editions of The Fruit Expert and The Vegetable & Herb Expert will be published this month.

Revised editions of the other 11 books will be published by February 2008.

Approved chemicals

In the meantime addendum sheets have been inserted into the existing stocks of those titles until the updated versions appear.

The sheets recommend approved chemicals instead of any out-of-date products which are mentioned in the books.
