Chafer Grub Nematode season is starting!

July 2017

 

 
 
 

What do nematodes do?
These tiny, microscopic worm-like creatures are watered into the turf. They then move through the soil infecting and killing Chafer Grubs.

Once a nematode has found and penetrated a pest larva through a body opening, it begins its destructive work on the pest. In order to convert the larvae into food, the nematode releases symbiotic bacteria. These bacteria spread throughout the larvae, multiplying rapidly while feeding on the host tissue and converting it into a form easily taken up by nematodes. The infected larvae die within a few days but the beneficial nematodes continue to multiply and develop in the host larvae. As soon as the nematodes are in the infectious third stage, they leave the host and start searching for new targets. The nematode population will slowly decrease once there are no new hosts present.
The nematodes used for Chafer Grub control can only be used between July and October when the soil is warm enough for it to be active.Nematodes will seek out and kill all Chafer Grubs within 14 days of treatment.They are harmless to humans, pets and wildlife.
Nematodes are sensitive to high UV, so should be applied on dull days with plenty of irrigation. Turf should be watered prior to application and after.
Dragonfli has pack sizes to treat all sized lawns from 10m2 to 500m2.

 
 
 
 

Chafer Grub larvae are now feeding on the roots of lawns in the UK.

Adult Chafers are often seen in May/June, with small grubs hatching from July onwards. These grubs immediately start feeding and are fully grown by the autumn, causing extensive primary and secondary damage. The primary damage often shows as yellowing of turf, where the grubs are feeding on the roots. The secondary damage is often worse when badgers and birds are attracted to the grubs to feed on. They then pull back large areas of turf to feed on the grubs.

   .
 Lawn damage caused by badgers hunting Chafer Grubs

As soil temperatures drop, the grubs stop feeding and go deeper into the soil. During the spring , they crawl closer to the surface, pupate and emerge as adults in May/June.


There are very few controls available to gardeners for this damaging pest.However, there is one very effective natural one - the use of Chafer Killer Nematodes.
 

Apply nematodes once evidence of Chafer Grubs has been seen

Simply by watering the diluted nematode pack directly into the lawn, the nematodes will seek out and kill Chafer Grubs within 2 weeks. Ensure the lawn is kept moist during this time.

Time to control Carrot Root Fly Larvae
 

June is a month where there is a high probability of Carrot root larvae attacking carrot crops.
These larvae develop from eggs normally laid in May and burrow into carrots causing extensive damage to the carrots. An early sign of carrot root fly activity can be bronzing and discolouration of the green top growth on carrots.
Once the larvae are present, the carrots become dis formed and in extreme cases un-edible. Netting and fleeces can help protect crops from carrot root fly adults but if the defences are breached it may be required to try and kill the carrot root fly larvae.


Carrot Root Fly larvae

There are no chemical insecticides available to gardeners for the treatment of this pest. However help is at hand with Carrot Root Fly Killer nematodes. These tiny eelworm-like nematodes are watered into raised beds or open beds. They are harmless to pets and children and other wildlife but are deadly to Carrot root fly larvae.
Carrot Root Fly Killer provides a safe, biological control of carrot root fly larvae. Repeat applications can be required for severe infestations or new generations of carrot root fly killer. Carrot root fly insect traps can also help to trap and monitor carrot root fly adults.

New Ecofective Bug Killer
 
 
Ecofective Bug Killer combines fatty acids and natural pyrethrum for effective control of many insect pests including Box tree moth caterpillars.
Natural pyrethrum is derived from Chrysanthemum flowers and is approved for use in organic gardening. The combination of the pyrethrum with fatty acids increases the effectiveness of this natural insecticide.
Pyrethrum breaks down in sunlight, so after 24 hours there are no harmful residues left on the plant. This means beneficial insects like Ladybirds and Lacewings are not harmed.

Ecofective is useful when you are faced with large scale infestations of pests like aphids, which breed very quickly. An application of Ecofective will help bring numbers down, which will then allow natural predators or introduced predators the time to catch up and destroy the pest infestation.

Pests controlled by this new natural bug gun include; Greenfly, Blackfly, scale insects, mealybugs, caterpillars and sawfly larvae.
   
          Mealybugs                Sawfly larvae       Greenfly

Ecoefective Bug Killer also kills wax moth grubs, so can be used to kill the grubs when cleaning out an old colony of bumblebees, as part of your hygiene measures to protect future colonies from attack.
Ecofective is supplied in a litre RTU bottle.
 
 
Plum Fruit Moths Flying Now!
 
Plum Fruit Moth has a slightly later flying season than Codling moth, so will be flying now and into July. 
 This is a key time to have your Plum Fruit Moth pheromone traps out and ready to catch the male plum fruit moths.

One Plum Fruit Moth trap will cover an area of up to 12 trees. The Dragonfli Plum Fruit Moth trap is also supplied with a long life lure, which means only one lure is required each season. Replacement lures can be bought each year.

The Plum Fruit Moth is a common pest of plums, damsons and greengages. The female moth lays her eggs near the plum fruit and once the eggs hatch, the larvae burrow into the fruit. The caterpillar is pinkish-white and about 10-12mm long and eat the plums from within.This sometimes is not observed until the Plum is cut into.When the caterpillar is fully fed it may exit the plum leaving a small hole. Infected fruit often ripen first.
 
Julian's Journal
 
Each year we seem to get a new invasive pest or an insect pest infestation that seems worse than other years.
This year Box Tree Moth seems to have taken hold in the south east, especially in London. This is a devastating pest of box plants and has wreaked havoc in some areas of France.
We have pheromone traps for the adults and we can use products like Ecofective Bug Killer on the caterpillar stage but we could do with a biological control.
This is an area we are investigating and hope to have some solutions for you in the future.
For more native pests, a surge in their activity is often weather related and may be worse due to the reduction in use of many broad spectrum insecticides. This is a good thing, as it also means more beneficial insects survive, the trick is getting the balance right, which is where we hope Dragonfli can help.

Plum Fruit Moth Traps

The  Plum Fruit Moth trap from Dragonfli uses a pheromone lure to draw the male moths into the trap. They then enter the trap and drown in the water inside.
This system uses no glue, which means the traps can be easily re-used each year, if a new pheromone lure is added to the trap.
The pheromone lure is attracting male plum fruit moths, so reduces the amount of eggs laid by females who fail to mate. This in turn helps reduces the Plum Fruit Moth population.

Beepol Bumblebee season is here!
 

Spring is here again and we are close to sending out the first Beepol bumblebees of the season. Live deliveries start in May. As a general rule of thumb, deliveries start first in the South of England and then work northwards. This is done to reduce any possible problems caused by cold temperatures and resulting shortage of pollen in the local environment.

This year we have two great Bumblebee hives designs to choose from, the Queen Bee range, launched last year and the new Villa 2017.
The Villa 2017 is our new standard design of wooden bee hive, designed to provide a sturdy, safe environment for the bees, whilst looking great in your garden. They incorporate a weatherproof roof and removable lid for access and viewing of the bumblebee colony housed within.
The Queen Bee hives are made to order, so please check for availability. For customers with Queen Bee hives or previous Villa designs, don’t forget to order your new Beepol colony for the 2017 season. If you have Lodges or Cabins, we regret there are no longer colonies produced that fit in these designs. We are offering an upgrade deal to existing customers for the new Villas, so please contact Sian at Dragonfli for details.

All our colonies will be treated with the natural bacteria; B401, against wax moths before they leave Dragonfli. However, customers should be aware that repeat applications may be required to protect bumblebee colonies from this nasty natural bee predator. B401 and a spray bottle can be purchased from Dragonfli. We suggest repeat treatments applied monthly to keep the B401 active.
We hope everyone enjoys their Beepol bumblebees in 2017.
 

 
Big year for natural pest control using nematodes
 
 
2016 saw some major insecticides withdrawn from the hobby and amenity horticultural sectors, especially those commonly used against turf pests. There are now no insecticides available to treat lawn pests such as Chafer grubs and Leatherjackets.
This presents a huge potential problem to green keepers, parks, sports turf management and gardeners lawns. Lawn pests can cause serious damage to grassland by the feeding they do on grass roots. This quickly turns large areas of lawns yellow as the roots are consumed. However the worse damage is yet to come!
The larvae and grubs of these insects catch the attention of animals and birds, which see them as an ideal food source. They then proceed to rip up lawns to find the grubs. This damage is especially bad when badgers are involved, as they rip up large areas of turf.

There is a natural solution in the form of nematodes, tiny microscopic eel like worms, which can be watered into lawns during the summer. They then seek out and kill the larvae and grubs of these pests. More on these natural enemies in a summer newsletter.
 
 
New nematode treatment for Carrot Root Fly
 

 
Carrot root fly is another pest with no insecticide treatments available to gardeners.
Last year Dragonfli carried out trials at RHS Harlow Carr gardens using a nematode against the carrot root fly larvae. The results were very successful with no damage being recorded in the treated areas. The trials are being repeated this year.
Dragonfli customers can now buy Carrot Root Fly Killer nematodes for the control of carrot root fly larvae  
Simply water the nematodes into raised beds or open beds where carrots are growing. The nematodes will then search for and kill the larvae in the soil. Repeat applications may be required as there are more than one generation of carrot root fly in a year.
Use the code CARROT10 at the checkout to get 10% off your order for this nematode.
The timing of the applications can be improved with the use of carrot root fly traps. These will catch adult carrot root flies on specially angled orange sticky traps designed to catch carrot root flies and not other insects.
 
Julian's Journal
 
I predict this is the year of the nematode!
The use of beneficial nematodes for pest control has been increasing steadily over the last few years but now they stand to be used more than ever, due to the withdrawal of several commonly used insecticides. The choice of whether to use biological control or not is now more, what else can I use to control certain pests? Nematodes are safe to use, provide effective control [ if used correctly ] and have no negative effects on the environment.
Here at Dragonfli we have been busy preparing lots of new nematode pack sizes for all types of garden sizes and for lots of different pests.

20m2 nematode packs
 
 
Beepol Villa 2017

The Villa 2017 is our new look Villa for this year.
The bees can be easily observed by removing the roof and looking through the ventilated top.
The entrance ledge has direct access in to the hive, where your 'guard bees' will often be seen patrolling!
The Tree Villa for raising the bees up onto trees, walls and fences is now available to order.
Our van runs are filling up, so order your Villa and hive now, for delivery towards the end of May and into June.

B401


The Wax Moth begins to emerge during June.
Although we will spray the cardboard colony box with B401 before we send you the bees, it is important for the Villa or Queen beehive to be sprayed too.
It will not stop the moth from getting in to the hive, but should stop the spread of the larvae and webbing it likes to leave.
The concentrate lasts for 2 years once opened, if kept refrigerated.
We have a B401 spray bottle pack this year, so you can have a dedicated B401 spray bottle at hand when needed.

Last chance to treat Leatherjacket larvae

This short, fat leatherjacket  larvae does a lot of damage to lawns from August through to the end of October. The recent warm weather does enable later applications but should not be delayed to long now.

Once you have evidence of this grub under your grass, it is time to apply nematodes.

Available in many sizes -  100m2, 500m2 , these nematodes will seek out and destroy Leatherjacket larvae within 14 days of use. Can be applied by watering can or hose end nozzle.

This is a natural solution for leatherjackets in lawns. Leatherjackets are the larvae of crane flies, otherwise known as Daddy-long-Legs. The majority of the eggs are laid late summer and develop into Leatherjacket larvae in the late summer- early autumn.

Stop these horrible pests ruining your lawn by using a biological control.

 

 

Red Mite Season

The warmer temperatures are perfect for Red Mite ( Chicken Mite) to increase in numbers.

ANDROLIS is the name of the product for controlling red mite and northern fowl mite on all birds.

It contains predatory mites that feed on red mite. They kill all stages of the parasites from egg to adult.

Red bird mite [ Dermanyssus gallinae ] causes significant stress to infected birds and anemia, which  sometimes leads to death. Birds show signs of nervousness and even cannibalism.

Chickens/ hens  and other birds infected with Red Mite also see a drop in egg laying.

ANDROLIS is easy to use and is 100% safe to the birds, the environment and humans.

Androlis is available in 4 sizes     M, L, XLXXL
