Nova Scotians won't be allowed to use pesticides on their lawns starting next spring

The NDP government introduced a bill Tuesday to ban the sale and use of non-essential pesticides across the province. It applies to lawn care in 2011, and trees, ornamental shrubs and flowers the following year.

"It is an opportunity put forward by our government to bring greater protection to our families and to our environment," said Environment Minister Sterling Belliveau.

The ban does not apply to farmers, forestry companies, golf courses and backyard vegetable gardens.

With so many loopholes, said Liberal MLA Andrew Younger, people will exploit the law.

Belliveau said there was widespread support for a ban on cosmetic pesticides during public consultations. His bill mirrors laws in Quebec, Ontario, New Brunswick and P.E.I.

Dr. Robert Strang, Nova Scotia's chief medical officer of health, said there are safe alternatives to the pesticides that achieve the same result.

Lawn-care professionals told CBC News they also support the ban and are waiting to find out which products will be deemed acceptable.

The Halifax Regional Municipality banned the use of pesticides in 2003 but doesn't have the authority to prohibit their sale.
