The Cost of Conifer Mite

Conifer mite costThere is nothing more worrying than seeing Conifer Mite damage on Leylandii or Conifers.  Not only is the ‘grey-browning’ of foliage unsightly but if untreated it will kill trees and hedges; resulting in rapid loss of screening and eventually a costly replanting.

Recent warm weather has already seen hatching of Conifer Mite, so monitoring for this pest should be happening now. Infestation is rapid and treatment must be carried out as soon as Mites are spotted, ensuring damage is reduced.

So what is the solution?

CertisOne recognised option for control is Certis Spraying Oil.   The Spraying Oil works in two ways.  Firstly it deals with the primary infestation, followed by the added benefit of making it difficult for migrating mites to re-attach to the foliage, further reducing the chance of re-infestation.  Mixed with water, the petroleum and surfactants in Certis Spraying Oil create a thick white emulsion, clearly identifying treated areas.

Other pests controlled include Cypress Aphids, Red Spider Mites, Mealy Bugs and difficult to treat scaled insects, which makes it an excellent all round product and not just a treatment for Conifer Mite.

The Unwanted Pillar of Society!

There’s a new pest on the block, increasing in numbers, defoliating trees and posing a serious threat to human health. Oak Processionary Moth

The larvae (caterpillars) of the “Oak Processionary Moth” (Thaumetopoea processionea) predominantly feed on oak, but also hornbeam, hazel, beech, chestnut and birch.

Although the leaf damage can be servere, Oak Processionary caterpillars pose a serious risk to human health. The caterpillars are covered in bristle-like hairs containing a chemical toxin. Human contact with the hairs can provoke allergic reactions manifested as skin rashes, conjunctivitis and respiratory problems such as pharyngitis and asthma. allergic reactionsHealth problems can occur even if the larvae are not handled as the hairs break off readily and are dispersed in air currents. Abandoned caterpillar nests contain shed caterpillar skins, pupal.

The likelihood of human contact is increased as OPM are most abundant on urban trees, along forest edges and in amenity woodlands.

Moth populations are well established and increasing in northern Europe in response to climate change. OPM is spreading in London and has been detected further afield and as far North as Sheffield.

So what is the solution? The biological insecticide “Dipel DF” contains naturally occurring bacteria which is highly effective at controlling caterpillars. Dipel DF is approved for use in 190 different crop types including vegetables, fruit, forestry, and amenity situations.

Although lethal to caterpillar, Dipel DF is non toxic, biodegradable and safe to other insects, fish, animals and humans and permissible in organic situations.  Once a caterpillar has ingested Dipel DF, it stops feeding in minutes Dipel DFand dies within 24-72 hours.

Dipel DF is available to purchase at www.progreen.co.uk

A 0.5kg packs is sufficient to treat 6666m2 (1.66 acres).  Full instructions and a safety data sheet are available to download at the above website.

Controlling moss on roofs

Moss is not only an issue on paths & surfaces but can also cause problems with roof tiling.Controlling Moss on Roofs

Damage can be caused when moss grows onto the top few millimetres of tiles causing them to lift & allow water to get between them.  Indirectly moss can also cause further damage in cooler weather when water in the moss expands, causing tiles to crack – again allowing water into the roofing void.

Treating moss on roofs can be done by using products such as MossGo. Click here to see our video
