Chemical and Non-chemical Control Options for Hylobius

Pine Weevil (Hylobius abietis) are a major problem on forestry restock sites and a particularly heavy outbreak can destroy up to 80% of plants.

Historically, plants were sprayed with insecticides either on the nursery or in the field in order to prevent or limit attack, however, there are increasing calls for the use of chemicals in the natural environment to be restricted meaning that alternative options need to be explored.

At Alba, we provide chemical treatment options when requested by the customer under controlled conditions on the nursery, however, we believe that other methods can be just as effective with far reduced environmental impacts.

 

Chemical Control Options for Hylobius – Alba is one of the only nurseries in the UK to have a mechanical spray race for the application of insecticide.

Race

We can offer a full plant spray or a reduced top-spray in conjunction with the use of WEENETS.

The accuracy allowed by the use of a mechanical spray machine means that the chemical remains effective for an extended period in the field, providing the following benefits:

  • Applied with maximum operator safety precautions
  • Every tree is treated
  • No need to carry out first season field inspections
  • Reduced need for top-up field sprays
  • Reduced health & safety risk associated with field spraying
  • Minimal environmental impact

Weevil

Alba has recently partnered with ICL to provide MERIT to the forestry sector.

MERIT FOREST is the only systemic pesticide for the control of Hylobius – it acts by both contact and systemic action.

The active ingredient – Imidacloprid – disrupts the nervous system of insects, but not mammals. Treated trees will not affect non-target insects.

Considerable testing of the product has taken place, with impressive results. A pre-planting application helps to reduce the gnawing damage caused by Hylobius to conifers during the year of application and significantly reduces severe tree damage and death versus untreated plants or even Alpha Cypermethrin.

Trials

MERIT FOREST is very gentle to the treated plant and does not damage new growth. It is also comfortable to use and handle when planting, with no allergic reaction to the user.

 

Non-Chemical Control Options – we believe that a number of non-chemical options can be explored in order to reduce the impact of Hylobius.

GOOD SILVICULTURAL PRACTICE including the use of containerised plants that lend themselves to excellent early establishment can be beneficial in the fight against Hylobius. This allows plants to get above the invading weeds and to become strong and girthy enough to withstand weevil attack. The application of controlled release fertilisers at the time of planting also boosts early development. Alba provides a range of fertiliser products that cost 3.1p per plant and the benefits of containerised trees are discussed below.

Extended Planting Season

Planting can be carried out throughout the year, provided there is sufficient moisture in the ground.

Ease of Planting

Hand planting is speeded up as the planters do not have to contend with different sized root systems. The uniform nature of the root plugs also lend themselves to mechanical planting.

Excellent Early Establishment

Rapid early growth also enables the plant to get above the invading weeds – saving time and money on early crop care. This can be supplemented by the application of our specially developed fertiliser.

Cell

ALBACOTE is a controlled release tree fertiliser specifically developed and tested for UK forestry. It is a blend of NPK suitable for all types of trees and sites which will release slowly ensuring excellent establishment and growth and does not leach out under excessively waterlogged conditions.

10g is applied to each tree at planting and one 1.5kg bag will cover one full tray or bag of Alba stock.

WP_20160608_11_05_40_Pro

WEENETS have been developed by Alba as a step towards reducing the amount of chemical used in the forest and to protect newly planted trees against  Pine Weevil.

The lightweight net is fitted to the tree at the nursery – each net is individually positioned around the root plug and lower part of the stem. Once planted out, the roots and side shoots can easily grow through the net and develop normally.

Planters have found the netted trees even easier to plant than regular stock.

WeeBar

WEEBARS can be used in conjunction with the WeeNet, the WeeBar plastic collar patented by Alba acts as a physical barrier to prevent weevil climbing the stem of the plant. Still in the trial phase, the collar is fitted at the nursery and incurs minimal additional costs per plant to the customer.

Controlled Release and Top-Dress Fertilisers

Over the years at Alba Trees we have spent time and resource researching the most suitable formulation of fertiliser for UK forestry application. AlbaCote has been a huge success when applied at the time of planting and results continue to be impressive.
We have recently launched a controlled release fertiliser for acidic soils and also an instant top-dress solution for application in the field.

ALBACOTE – Controlled Release Fertiliser
15-25-6
AlbaCote is a uniquely formulated controlled-release fertiliser containing Nitrogen, Phosphorus and Potassium as well as vital trace elements for use in woodland planting — both new planting and restock sites.
Each granule of AlbaCote has a uniform composition for a more even nutrient release pattern.
AlbaCote consists of a strictly controlled blend of nutrients surrounded by an elastic resin coat. The rate of nutrient release is directly affected by soil temperature.
Trace elements: 0.01% Boron; 0.05% Copper; 0.27% Iron; 0.06% Manganese; 0.015% Molybdenum; 0.015% Zinc.
In UK forestry conditions, AlbaCote will provide a gradual release over a period of two growing seasons. The application of AlbaCote at the time of planting provides an early boost to top and root growth.
AlbaCote is safe to use and environmentally friendly.
Rate of Application: 10g per tree
Cost per Plant: 3.1p

ALBACOTE ‘B’ – Controlled Release Fertiliser for Acidic Soils
9-20-8 + 3Mg0 + 0.1B
Like the original AlbaCote, we have developed a uniquely formulated controlled-release fertiliser that is specially developed for use on acidic soils to alleviate problems including Boron deficiency.
AlbaCote ‘B’ contains ten times the Boron of the original AlbaCote.
Low Boron availability is particularly common in acidic soils and AlbaCote ‘B’ looks to counter against the deficiencies this may cause including reduced root development and environmental stress that will affect the growing tips leading to multiple leaders and dieback of the growing buds. AlbaCote ‘B’ is safe, reliable and easy to use and is environmentally friendly.
Rate of Application: 10g per tree
Cost per Plant: 3.1p

ALBATOP – Instant Top-Dress Fertiliser
13-15-13 + CaO + SO3
AlbaTop is a top-dressing mini homogenous granule with advanced technology that encourages healthy and vigorous root growth and hardy top growth.
The long-lasting nutrients produce healthy plants with good colour and is safe and easy to use at high application rates. The fine, homogenous granule allows for an even distribution.
AlbaTop utilises a proven advanced technology for best results that minimises the risk of Nitrogen being lost through natural processes and Phosphorus being locked up in the soil.
The advanced coating is a water soluble polymer technology that is unique to this product. This ‘shield’ protects Nitrogen and Phosphorus from excessive gasification and leaching, allowing the nutrients to be more readily available to the plant precisely when needed.
AlbaTop has a positive environmental impact and protects water courses from leached nitrates and phosphates.
Rate of Application: 25g per tree
Cost per Plant: 3.1p

AlbaCote Fertiliser

Woodland nutrition is complex. Different sites will have different requirements and it is often too expensive or impractical to address individual site requirements. A more general approach is often used, usually involving broadcast applications of rock phosphate on to sites.

This approach, however, has significant drawbacks:

  • It is not targeted and weed species benefit too
  • It is an expensive and dirty operation
  • The potential for run-off and pollution of water courses is high, this also leads to economic loss

The application of a granular, coated fertiliser direct into the planting hole at the time of planting overcomes these problems in a simple and cost-effective way.

 Harvesting

Figure 1: Typical harvesting site.

AlbaCote

AlbaCote (15-25-6) is a uniquely formulated controlled-release fertiliser (CRF) containing Nitrogen (N), Phosphorus (P) and Potassium (K) as well as vital trace elements for use in woodland planting – both new planting sites and restock sites.

N – involved in the production of new tissue. Good levels of nitrogen in the plant over winter provide a good start in spring.

P – vital for energy transfer processes in plant tissues and important for root development.

K – essential for growth processes including photosynthesis as well as being vital for plant hardiness.

How Does AlbaCote Work?

In contrast to other CRF products, each granule of AlbaCote has a uniform composition – it is NOT made up of individual straight fertiliser components. This provides a more even nutrient release pattern.

AlbaCote consists of a strictly controlled blend of nutrients surrounded by an elastic resin coat. The rate of nutrient release is directly affected by soil temperature.

In UK forestry conditions, AlbaCote will generally provide a gradual release over a period of two growing seasons. This is considered sufficient to get young roots growing healthily and in search of naturally occurring nutrients.

Diagram

Figure 2: Diagram showing the nutrients contained within AlbaCote and how it works.

AlbaCote (15-25-6)

15% Nitrogen (3% as nitrate, 12% as ammonium)

25% Phosphate (P2O5)

6% Potash (K2O)

(16% Sulphur (SO3))

Trace elements:

0.01% Boron; 0.05% Copper; 0.27% Iron; 0.06% Manganese; 0.015% Molybdenum; 0.015% Zinc

Environmental Considerations

Guidelines on the application of fertiliser, produced by Scottish Environmental and Rural Services recommend that:

Fertiliser must be applied on land in such a way and at such times that the risk of pollution to the water environment is minimised.”

The use of AlbaCote CRF directly addresses this requirement by the accurate placement of nutrients and the fact that it does not leach out under excessive waterlogged conditions.

Ergonomic Considerations

The quantity of AlbaCote required per plant is much less than traditional ‘powdered’ fertilisers. In addition, AlbaCote is dry and clean to handle. Together, these make the application more cost-effective and less hazardous for planters.

AlbaCote is supplied in 1.2kg or 1.5kg bags, with only 10g per plant required at the time of planting.

Fert

Figure 3: 1.5kg bag of AlbaCote, with a 10g sample.

New Planting Sites

For a number of years Alba has been supplying CRF products to native pine schemes in the Scottish Highlands to aid establishment on what are often poor nutrient sites.

These sites are subject to strict controls to ensure minimal environmental impact. The application of our CRF products enables these objectives to be met whilst providing an excellent start for the young trees.

“The use of Alba’s CRF has made a significant difference to the success of establishing trees on poor nutrient status sites. Application of CRF has meant the difference between getting broadleaves established or not.”

Restock Sites

Historically, little regard has been given to the potential benefits of CRF on restock sites where it is assumed residues from the previous crop will provide adequate nutrients for the replacement trees.

However, with an increase in residue harvesting, the widespread practice of burying residues and planting mounds becoming more commonplace this is no longer a safe assumption to make.

Slow early growth extends the period of risk for young plants – making them susceptible to vermin, weevils and weed competition. Ideally, plants should have sufficient vigour to overcome such threats in the first two years otherwise an extended maintenance period is likely with considerable additional costs.

The application of AlbaCote at the time of planting provides an early boost to both top and root growth – the latter leading to improved access to composting residues and naturally occurring nutrients.

AlbaCote trials have taken place on restock sites across the country, with encouraging results.

Chemical and Non-chemical Control Options for Hylobius

Alba’s cell grown stock and a range of additional options – including controlled release fertiliser and protection against weevil damage – mean that we are the ideal choice when planting restock sites.

Flood Packs

In addition to a range of native and productive species already available, we are now offering ready-mixed riverside packs to provide an initial step towards flood prevention planting.

Erratic and unseasonal weather is becoming increasingly common in the UK, with damage and disruption to thousands of homes and businesses becoming almost commonplace.

Yet again, the winter of 2015-16 saw severe adverse weather across the UK and with climate change becoming ever-apparent – more natural and effective solutions at water management are being explored, including the planting of trees to reduce flood flows and improve infiltration rates of woodland soils.

Each mix includes a range of species specifically suited to watercourse and surrounding areas and can be supplemented by other species to suit local soils and landscape – please visit our retail site for more details:

http://www.buy-trees-online.co.uk/shop/flood-prevention-packs

In addition to the use of specific species in the immediate vicinity of water courses, larger-scale plantations in the surrounding area will further emphasise the role of woodlands in water management – please contact our Sales Office for any enquiries.

 

Conifers for Colleges

Everyone involved in our industry over the past few years has seen many of our beloved conifers hit by successive rounds of disease and there have been increasing calls to consider our long term options.  At Alba, we began to grow ‘alternative conifers’ so that we could provide plants for trials, but also find out more about how these species can be best grown on the nursery.  Whilst foresters are looking at silviculture and sawmillers are looking at timber values, the nursery trade must look at growing these trees to an acceptably high quality standard at the lowest price, so Alba has been trialling many different growing methods to reduce the cost to the minimum possible which will allow industry to make an informed decision about the viability of each species.

In 2014, we were approached by the Royal Forestry Society to partner them in an exciting project concerning alternative conifers in an educational and research context.  They presented the ‘Conifers for Colleges’ Project:

Aim: Improve the level of understanding around conifers while also providing a valuable forestry Conifers_Collegeslearning resource to improve the knowledge and skills of the forestry sector as a whole.

 Objectives:

  • Raise awareness for the value both commercially and socially of conifers in the UK.
  • Provide forestry/arboriculture students with the opportunity to gain practical forestry learning opportunities.
  • Provide colleges with a forestry based onsite learning and research facility.
  • Research the potential of a range of new (novel) species for their value within the timber

Alba offered to donate alternative conifers to 5 Colleges, who would plant the trees within an agreed layout and monitor progress.  Tubex also kindly agreed to donate tree shelters.  The 5 Colleges were:

On 5 November 2014, the project was launched with the first planting at Moulton College and we wish it all the very best and hope that it contributes to the learning of our young foresters.
