 I just have to say that I am so impressed with Nemaslug.
On Wednesday night, and again on Thursday morning,  my back and front lawns looked like the injun's were massing for attack at The Little Bighorn !  Slugs everywhere,  there were armies of the infernal things.  Then my order of Nemaslug arrived ..... on Friday evening it drizzled, ideal for waging war.  My neighbors must have thought, "The old fool has gone gagga" as I watered the lawns with my 2 gallon watering can.  But on Saturday morning, as the sun broke over The Little Bighorn, there was not an injun in sight.

Nemaslug

Nemaslug protection for Potatoes
To give potatoes maximum protection apply Nemaslug when the plants first start to show.  A second drench can be applied when you see the flowers setting on the plants.  This is when the tubers are starting to form and are at their most vulnerable.  One application of Nemaslug will protect potatoes for at least 6 weeks.

 Safe for children, pets and wildlife, Nemaslug is so easy to apply.  Just dampen the soil and then drench the nematodes into the ground using a watering can or through a garden feeder (see over for instructions).  Make sure that you apply the solution to the soil and take care to apply it to the sides of paths and anywhere else that slugs might hide. 

Nemaslug is a unique natural product, containing microscopic worms (nematodes) which seek out slugs, stop them feeding on your plants within 3 days and then kill them. Nemaslug controls all common species of small to medium sized slugs (up to aprox 8cm - 2.5-3 inches). Use all year round under glass/indoors, outdoors early spring (Late February early March dependant on area & temperature) up to late November. At the time of application soil temperatures should be a minimum of 5⁰C (40⁰F) Nemaslug stays active in the soil for up to 6 weeks from time of application.

Nemaslug effectively controls slugs with no risks to children, pets and wildlife. It provides long lasting protection right through the susceptible growing period of young plants (up to six weeks), it is also unaffected by wet weather. To buy Nemaslug click here
Nemaslug contains concentrated doses of nematodes, which are specific natural enemies of slugs. These microscopic creatures do occur naturally in the soil, but the increase in slug numbers during the Spring and Autumn leaves them outnumbered. Therefore, each pack of Nemaslug contains millions of reinforcements. These reinforcements both kill and deter slugs, giving young plants the protection they need to develop and grow.

Once applied by watering can, the nematodes move through the soil, seeking slugs. They penetrate the pest and stop it feeding.
This occurs after a few days, thus quickly protecting your plants, and the slug dies several days later, underground. The nematodes then reproduce inside the dead slug, releasing a new generation of hungry nematodes that quickly disperse to find more pests.

 Start your control regime early and you will be able to target the young slugs growing under the ground feeding on humus.
Nemaslug uses the nematode Phasmarhabditis hermaphrodita, which was discovered by scientists at the government research institute at Bristol, England.
One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving at least six weeks control of slugs. This is generally enough time for seedlings and bedding plants to get well established.
Nemaslug is easy to apply and does not leave any unsightly residues.
The majority of the slugs will die underground, so don't expect to see dead slugs lying around.

Applying Nemaslug 
Since Nematodes (Nemaslug & Nemasys products) are living organisms, you should order product as required and must be used in one go it cannot be stored once it is made up. When you receive your pack, place it in the refrigerator immediately and use within the use by date (which can be up to four weeks)
Apply to moist soil. The soil temperature should be 5ºC (40ºF) or over (this is when plants start to grow). Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls temporarily after you have applied Nemaslug. 
Unlike some controls, Nemaslug continues to work well during wet weather - exactly when you need protection against slugs!
Nemaslug might affect water snails. To avoid harming them keep the treatment 15 cm (6") away from ponds.
If you have a heavy clay area, ensure you apply Nemaslug to well worked soil. Nemaslug is less effective on cloggy clay soil, which has not been worked and/or has become waterlogged.
Nemaslug comes in pack sizes to treat 40 sq.m (50 sq.yds) and 100 sq.m (125 sq.yds).

A regular regime of using Nemaslug every six weeks is the best way to keep slugs at bay throughout the growing season.

Nemasys Vine Weevil Killer

Nemasys H effectively controls vine weevils with no risks to children, pets and wildlife. It controls vine weevil larvae in the soil – where these pests are most destructive. Unlike chemical alternatives, Nemasys H is effective against all larval stages.

Apply anywhere, indoors or outside, onto soil or compost that contains the larvae.

Nemasys Vine Weevil Killer is the simple solution to control vine weevil.
This already successful product has now been substantially improved. Over many years we have been working with HRI, the leading UK based horticulture research group, to bring forward this exciting development.
Nemasys Vine Weevil Killer contains a newly found nematode, Steinernema kraussei. This new nematode has some very impressive benefits including;
• Consistently greater effectiveness over and above the previous     nematode (Heterorhabditis megidis)
• Ability to work at cold temperatures. This new nematode will work at temperatures down to 5ºC (40ºF) (Heterorhabditis required a minimum of 12ºC (54ºF)), so that you can protect your plants earlier in the year.
• Most gardeners notice that they have a problem with vine weevil in February/March (this is when they notice their plants are sick), previously they had to wait until April/May to apply Nemasys Vine Weevil Killer, now they can use the product straight away from March onwards.
• Prevention is better than cure, so it is better to apply the product in autumn, before the problem develops. Again the new Nemasys Vine Weevil Killer nematode will provide much improved performance here. In particular, gardeners can apply it well into November, providing a much longer application window.

To keep a minor problem at bay, one autumn treatment (September - November) should be adequate.
For a serious infestation, treat in the spring and again in the autumn
Nemasys Vine Weevil Killer will kill larvae present in the area and protect against further larvae damage for up to four weeks.
Apply when the soil temperature is at a minimum of 5ºC (40ºF) and the vine weevil larvae are present. Outdoors, this is usually from March to November.
Indoors, vine weevil can be controlled year round.
Apply directly to the soil around the roots.

Nemasys Vine Weevil Killer is available in pack sizes of 160 pot or 12 sq.m/14 sq.yds or 100 sq.m/125 sq.yds

Nemasys Leather Jacket Killer

Leatherjackets are the larval stage of the crane fly or daddy-long-legs. Leather jacket larvae are about 2.5cm (1" long), greyish black in colour, legless and with no distinct head.
In summer leatherjackets pupate. In August they start to lay eggs re-infesting lawns. Within two weeks eggs hatch. The young start to feed, continuing throughout winter, ready to gorge on grass roots in spring. Grass growth slows and yellow patches appear. Grass is easily pulled up, with little or no root growth.
In August gardeners may see clouds of daddy-long-legs emerging from lawns in the early morning and this, as well as the listed damage, are sure signs of leatherjacket infestation.
Starlings peck at the grass in an attempt to eat the grubs.
Wildlife, such as foxes and badgers, can also create a lot of damage as they dig up your lawn in search of grubs for food.
There is no chemical control for leatherjackets.
Use Nemasys Leather Jacket Killer to deal with a leatherjacket infestation.

Apply when the young leatherjackets are active in the soil, this is typically late August through to the end of October.
When you start to see the adult daddy-long-legs in your garden (towards the end of August) you will know that in a few days they will be laying eggs. These will hatch quickly, therefore, aim to apply about a week to two weeks after you see the adults.
Apply to moist lawns when the soil temperature is above 12ºC (54ºF) and water them in well. The nematode needs to be washed well in so that they reach the roots where the leatherjackets will be. Make sure the lawn does not dry out after applying nematodes.
Immediately after applying the nematodes, water the grass well so the nematodes are washed into the soil to reach the roots where the leatherjackets will be. Make sure the lawn does not dry out after applying nematodes. Keep the lawn well watered for at least two weeks.
The nematodes (Steinernema feltiae), seek out the leatherjackets and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey.
Each pack of Nemasys Leather Jacket Killer will treat 100 sq. m/125 sq yds.

Nemasys Chafer Grub Killer

Apply to moist lawns during August and early September. This is when the young grub larvae are active and the temperature is above 12ºC (54ºF). Despatched when available direct from the Laboratory during late July to early August.
Immediately after applying the nematodes, water the grass well so the nematodes are washed into the soil to reach the roots where the chafer grubs will be. Make sure the lawn does not dry out after applying nematodes. Keep the lawn well watered for at least two weeks.
Do not apply later than September, since the grubs start to move down deeper in the soil and become inactive until the following spring.
The nematodes (Heterorhabditis megidis) seek out the chafer grubs and attack the pest by entering natural body openings. Once inside, they release bacteria that stops the pest from feeding, quickly killing the pest. They do not stop there. The nematodes reproduce inside the dead pest and release a new generation of hungry infective nematodes, which disperse and search for further prey.
There are two pack sizes. One treats 20m2 whilst the larger pack will treat 100 m2 / 120 sq.yds.

Caterpillar and Codling Moth

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.

 

• The caterpillar stage of the butterfly and moth's lifecycle comes in a vast range of sizes, shapes and colours. Fortunately very few of these are of any problem to the gardener that need controlling.
• The most common of the troublesome ones are the distinctive Large and Small Cabbage White Caterpillars, up to 40mm and 25mm long respectively. The Large Cabbage White has distinctive yellow and black markings and a hairy body. The Small Cabbage White Caterpillar is pale green with a velvety appearance. They both have two generations a year with caterpillars occurring from spring to early autumn.
• The Gooseberry Sawfly is a pest that attacks gooseberries and red and white currants and can strip them of all leaves. All three species of Gooseberry Sawfly Caterpillars are up to 20mm long, pale green and with two of the species being heavily marked with black spots. Damage starts mid to late spring, but there can be several generations in a season.
• The Codling Moth Caterpillar is small and white with a brown head. It burrows into the fruit of apples and pears in mid to late summer. By the time the fruit is ripe they have finished feeding and drop on to the bark of the tree and the soil immediately underneath to overwinter ready for the moths to emerge in the late spring.
• Indoors, caterpillar damage can occur outside the usual times. 1

 What damage do they do and how do I recognise it?:

• Cabbage White Caterpillars can decimate a vegetable plot, especially brassicas or ornamental beds, especially nasturtiums. The Large Cabbage White feeds mainly on the outer leaves leaving holes and sometimes completely stripping leaves. The Small Cabbage White feeds mainly on the hearts of cabbages and other brassicas.
• By the time that the fruit is ready for picking the Gooseberry Sawfly can completely strip the leaves of the fruit bushes leaving them severely weakened and producing a poor crop the following year.
• The Codling Moth feeds on the core of the fruit of apples and pear and to a lesser extent walnut and quince. When they have eaten the fruit they exit leaving a small reddish brown hole in the skin with brown droppings know as frass. Upon cutting the fruit open you may find that there is very little left that can be eaten.

 Nemasys Caterpillar and Codling Moth Killer:
 

• Nemasys Caterpillar and Codling Moth Killer is the simple solution to control caterpillars.
• To control caterpillars apply as soon as the caterpillars are first seen applying to all leaf surfaces where the pest is present. Make sure to spray pests with a solution as caterpillars not directly sprayed will not be controlled.
• To control Codling Moths apply September to October to the trunk of the tree/main branches and to an area of soil equal to the tree cover above.
• Wet the area before applying the nematodes and apply with a pump sprayer so that all areas are treated. The pack contains sufficient for two further applications at 5 to 7 day intervals, this ensures that all hatchings are targeted.
• The nematodes (Steinernema carpocapsae), attack the pest by entering natural body openings. Once inside, they release bacteria that stops the larvae from feeding, quickly killing it and breaking the pest's lifecycle.
• Nemasys Caterpillar and Codling Moth Killer is available in a pack to treat 3 x 40m2 of open ground or up to 20 trees.
