Text on screen: New Pest Management Practices for the Control of Wireworm
[The video opens with a panning image of a tractor in a potato farm.]
[Cut to close up of potato farmers riding tractor.]
Narrator: Wireworms have become a major pest for Canadian farmers.
[Close up of wireworms in soil.]
They're the larva of the click beetle.
[Cut to high angle shot of a wireworm being dropped into the bottom of a plant pot.]
At the larva stage they live in the soil and eat the roots of plants.
[Cut to medium close up of rollers.]
Wireworms affect a wide variety of crops…
[Cut to medium close up of farmer in tractor.]
…such as root vegetables and grains.
[Cut to very wide shot of tractor in grain field.]
[Cut to close up of potatoes.]
However potatoes are the most affected.
[Close up of sliced open potato close up with wireworms on it.]
[Medium shot of wireworms on potato.]
In Prince Edward Island alone the potato board estimates…
[Close up of potatoes being processed.]
[Close up of processors picking through potatoes on a conveyor belt.]
…it costs farmers 6 million dollars a year in pest management measures and crop losses.

Traditionally, organochloride and organophosphate insecticides have been used to control wireworms.
[Cut to close up of potato shavings on scale.]
In Canada many of these broad spectrum products…
[Cut to wide shot of scientist in greenhouse.]
[Close up of scientist dissecting a flower.]
…are no longer available…
[Cut to very wide shot of potato harvester and farmer in field.]
…or are being phased out.
[Close up of potato harvester.]
With limited insecticide control available…
[Cut to wide shot of farmers riding tractor inspecting potatoes.]
…the wireworm population is growing and spreading.
[Cut to tilting close up of Dr. Christine Noronha inspecting potatoes in milk crate.]
Thanks to some pioneering research by Agriculture and Agri-Food Canada scientist Christine Noronha there is positive news.
[Cut to oncoming wide shot of tractor in field.]
She's working with Prince Edward Island potato farmers…
[Panning close up of potatoes.]
[Cut to wide shot of two tractors in mustard field.]
…using brown mustard as a rotational crop to fight the pest.

Dr. Christine Noronha: It has a specific glucosinolate in its roots which is actually toxic to insects when they chew on it.
[Cut to very wide shot of mustard field.]
Narrator: With mustard, the infestations of wireworm…
[Close up of mustard crops.]
…have been reduced to manageable levels but not eradicated.
[Cut to very wide shot of tractor and farmer on cultivated soil.]
Noronha is now exploring buckwheat…
[Close up of buckwheat crop.]
…grown at a crop rotation with mustard…
[Cut to wide shot of farmers in potato farm.]
[Medium shot of farmer tending to potato farm.]
… and potatoes as a control for wireworms.
[Close up of farmer splitting potato to show lack of pest interference.]
Participating farms have seen further and significant reduction…
[Cut to medium close up of Dr. Noronha examining potatoes in a milk crate.]
…of wireworm population.
[Cut back to medium close up of Dr. Christine Noronha discussing pest management in her lab.]
Dr. Christine Noronha: It is a green solution it doesn't use insecticides so you are doing it in a sustainable way.
[Cut to tilting close up of buckwheat seeds in petri dish.]
Narrator: Chemists are checking physical properties of buckwheat…
[Cut to very wide shot field of buckwheat.]
[Close up of buckwheat crop.]
…hydrologists will check on how growing buckwheat benefits the water table…
[Cut to tilt shot of Dr. Noronha examining a specimen through a microscope in her lab.]
…nutrient management experts will examine buckwheats' ability to soak up excess nutrients in the soil…
[Cut to wireworms on top of soil.]
[Extreme close up of wireworms on potato.]
…and an engineer will study soil properties.
[Cut to wide shot of Dr. Noronha walking with an assistant in her lab.]
The research by Noronha is part of a 1.8 million…
[Cut to wide shot of potato farmers loading crates on a tractor.]
…dollar project involving 17…
[Wide side angle shot of tractor moving across potato field.]
…scientists at Agriculture and Agri-food Canada research centers…
[Extreme close up of a potato sample being collected by a researcher.]
…across the country.
[Cut to wide shot of Dr. Noronha and assistant examining potatoes in milk crates.]
The research is a great example…
[Cut to wide shot of researcher in lab walking towards camera holding test tubes.]
…of how agricultural science…
[Over the shoulder shot of researcher holding a potato and weighing potato shavings.]
[Close up of researcher collecting plant samples.]
… in recent decades…
[Cut to wide shot of farmer working soil.]
…to become much more multidisciplinary…
[Close up of mustard crops with tractor emerging from left side across the screen.]
…and protective of the environment.
