When Becker Underwood's Sue Gibb moved to her new house in The Witterings, Sussex last September she discovered that
apples on two of the apple trees in her seaside garden were inedible they were so full of holes. She quickly decided to
practice what she preached and treat them with the new Nemasys Codling Moth Killer.
"I immediately treated with Nemasys Codling Moth Killer and this year they are untouched by the Codling Moth caterpillars.
Trees in a seaside garden struggle against the elements in any case so they certainly don't need the extra burden of
Codling Moths," says Sue. "I know the nematodes work but it is even more satisfying when you apply them in your own
garden and save your own produce."
Commercial growers have been successfully using the nematode Steinernema carpocapsae for some years on the Codling Moth
and now it is available to everyone.
To kill Codling Moths the nematodes are used to control the over wintering pupae on trees and ground from September till
the end of October. The nematodes are applied with a pump sprayer during the evenings or on dull days.
Nemasys Codling Moth and Caterpillar Killer is a natural product, is safe to use on food products and is harmless to children, pets and wildlife.
[top] Nematodes a Hit at Harrogate
Visitors to the Harrogate Spring Flower Show (24-27 April) flocked to the Nemaslug stand to see nematodes at work
attacking slugs. The bright and bold stand featured a central viewing area where visitors could see the nematodes through
the special magnifiers.
“It really helped people to understand how Nemaslug works in conjunction with nature to protect plants from slugs,” said
Sue Gibb, Becker Underwood’s customer services manager. “We could really show people the difference between plants
protected by Nemaslug and those not.”
A new free pest poster was also in great demand. To download a copy, click here.

Nematodes on Show
There's a new and very visual attraction on the show circuit this year - see slugs being attacked by nematodes! Becker
Underwood, the world's largest producer of beneficial nematodes and maker of Nemaslug slug killer, is exhibiting at
various shows this year. You can actually see the power of nematodes using the high powered magnifiers to view the tiny
creatures attacking slugs, crawling over them.
Home and garden Brassica and apple growers will be pleased to learn that the dreaded Cabbage White Caterpillar and Codling
Moths in fruit trees can be controlled by nematodes. Commercial growers have been successfully using the nematode
Steinernema carpocapse for some years on the two pests and now it is available to everyone.
The nematodes are applied directly to the cabbages and other brassicas as a wash. Three applications are used as soon as
you see the pest to kill caterpillars that will hatch over a period of time. Says allotment holder, Sue Hinton, "I was
amazed with the results when I used it. After the first application most of the caterpillars disappeared but you need to
use a further two applications five days or a week after each other to ensure all hatchings are killed. The solution
needs to be applied to all leaf surfaces and you need to make sure that you spray the pest. Pests not directly sprayed
will not be controlled so do make sure that you hit them."
Cabbage White Caterpillars are also responsible for eating ornamentals, especially nasturtiums.
For Codling Moths the nematodes are used to control the over wintering pupae on trees and ground from September. The
nematodes are applied with a pump sprayer during the evenings or on dull days.
Nemasys Codling Moth and Caterpillar Killer is a natural product, is safe to use on food products and is harmless to
children, pets and wildlife.

Nematodes and potatoes
Branston Ltd, one of the country's leading potato suppliers, is helping their growers discover just how good Nemaslug is
at controlling slugs. Based in Branston, Lincolnshire, with further production sites in Somerset and Scotland, the company
has an annual turnover of more than £100 million and is Tesco's largest fresh produce supplier, sourcing around 400,000
tonnes of potatoes a year.
Slugs are a serious and potentially very costly problem for potato growers, so Branston is keen to find an effective
solution. Following successful field trials in 2006, Branston encouraged a number of their growers to use Nemaslug during
2007. The initial target was to treat 100 hectares with Nemaslug, but due to the wet and humid season demand increased to
over 450 hectares.
"This year 30 of our growers tried Nemaslug and it was so successful that we are encouraging more of them use the product
in 2008," says Dr Andy Barker, R&D Manager at Branston.
Branston recommends Nemaslug to its growers and supports them to ensure its correct application. Keeled slugs (Milax &
Tandonia spp.) are particularly problematic in potatoes as they are more active underground and therefore harder to
control with conventional pesticide pellets. "Nemaslug works well in the places that pellets can't reach," says Andy.
Water is key to successful growth and also to enable nematodes to reach the slugs underground. When the weather is dry
the nematodes need to be watered in well. In the garden, the judicious use of a hose pipe or sprinkler is sufficient to
wash them in. Branston and Becker Underwood are collaborating to develop application through the standard raingun so that
growers will be less reliant on the weather.
"We're keen to encourage the use of Nemaslug, either as a continuous programme or in conjunction with other modes of
control as part of our Integrated Crop Management strategy (ICM)," continues Andy. "As Branston supplies Tesco and
follows the Nature's Choice guidelines, reducing the number of slug pellets used is very attractive. Using environmentally
friendly controls, such as Nemaslug, can help towards a greener environment and a more sustainable approach to slug
control."

Stonehenge siege lifted
English Heritage is winning its battle against invading forces at Stonehenge, Wiltshire thanks to native nematodes.
Hosting 800,000 human visitors a year is one thing, but when the famous landmark found chafer grubs plaguing its grass
pathways, the world-renowned visitor attraction needed help! It came in the form of Nemasys Chafer Grub Killer, produced
by Becker Underwood, the world's largest producer of nematodes, which was applied to 5000 sq m of grass to the south-east
of the stones.
Chafer grubs, one of the top ten garden pests according to the RHS, had caused problems for years by eating the grass
roots. This was exacerbated by jackdaws pulling up the grass to seek out the grubs, resulting in unsightly bald patches.
Add to that the constant flow of visitors and English Heritage had to keep moving visitor paths away from the damage that
encircled the famous stones. There was yet another problem too - when the chafer grubs hatched, the resulting swarm of
beetles would fly up at the visitors who found it extremely off putting to say the least.
Due to the large number of visitors including children and with local wildlife and sheep grazing in the neighbouring
fields, there was no way that English Heritage wanted to resort to chemicals so they had to come up with a natural
environmentally friendly solution - Nemasys Chafer Grub Killer. Within a week of the first application, back in September
2006, the secondary damage from wildlife reduced considerably. A review of the result in April 2007 has led English
Heritage to order more Nemasys Chafer Grub Killer - enough to treat an area twice the size of the original application.
Says English Heritage's Chris Bally, Landscape manager for Stonehenge and the south-west, "Nemasys Chafer Grub Killer has
cured the treated areas. We found it extremely effective and chafer grubs have not caused us a problem at all this year
on the treated areas. Now we are targeting other infected areas and hopefully we will not have a chafer grub problem at
all in a couple of years."
