Spray targets 80,000 hectares of N.B. forest as spruce budworm makes inroads

New Brunswick has just finished spraying more than 80,000 hectares of forest against the spruce budworm, the dreaded insect that infests the province every 30 years or so.

In recent weeks, the spray program focused on the north, where the spruce budworm continues to make its way from Quebec.

Last summer, images from Campbellton, where a colony of spruce budwormmoths took over a car dealership, caught the attention of people all over New Brunswick.

Since then, scientists agree, the insect has gained ground in the province, with hot spots showing up aroundCampbellton, Dalhousie, Balmoral, Charloand just west ofBathurst.

It wasfrom the Charlo airport in the past month that a dozen planes took off every day atthe crack of dawn to fly over forests with loads of insecticide.

Each plane carriedbetween 1,500 and 2,000 litres of BTK,a biological insecticide that targets the spruce budworm.

A controversial spray program during the infestations ofthe 1970s and 80s was aimed at New Brunswick forests at large and endedup spraying chemicals on more than half of them.

But now, with GPS technology and surveys of forests done beforehand,the spraying is more targeted.

A team of 30 people worked at the base in Charlo, including pilots, controllers and engineers.
