2.1.7 Water Sources for Pesticide Applications

 

When sourcing water for pesticides applications wild blueberry producers should always do the following:
-Test water for quality and pH before use
-Adjust pH of water in tank with a buffering agent when water is above a pH of 7.
-Use pumps that have safety systems that prevent spray water backflow
-Mix pesticides away from the water source
-Use nurse tanks where possible

      back to top
 

2.1.8 Pesticide Safety and Handling

 

Wild Blueberry producers will follow all pesticide labels instructions with regard to pesticide safety and handling. In addition wild blueberry producers will have on hand during application:
-all applicable safety equipment for the product being applied (ie. Nitrile gloves, rubber boots, respirator, goggles, spray suit etc.)
-spare safety equipment
-pesticide spill kit
-poison control centre number
-pesticide label including PCP number

      back to top
 

2.1.9 Pesticide Applications

 

Wild blueberry producers will strictly follow all pesticide labels as well as local provincial and municipal regulations. Growers should consider using GPS and other technologies for increased precision of pesticide applications, including the following.
- GPS tracking and Self steer technology
- Variable rate flow monitors
- Multiple GPS controlled zones on spray booms

Wild blueberry producers will only apply pesticides allowable by the markets to which those berries are being shipped to. All growers follow broker and processor guidelines with regard to products allowable for their markets.

Growers must follow PMRA guidelines regarding tank mixes

  2.2.1.2 Identification
  Weed identification is critical to proper management.  Growers have quick access to available weed id sources. The Wild Blueberry Information Network through Dalhousie University, Agriculture Campus has many weed id factsheets.
 
http://www.dal.ca/sites/wild-blueberry/publications/fact_sheets/weeds.html
      back to top
  2.2.1.3 Physical Controls
 

Growers should physically remove certain weed species when they first appear or just prior to harvest.  Vetch, goatsbeard, braken fern, goldenrod are examples of weeds that are pulled or clipped when densities are low to prevent weed spread and improve harvest efficiency.

      back to top
  2.2.1.4 Cultural Controls
 
2.2.1.4.1 Equipment Sanitation

Harvesters, mowers and other equipment should be cleaned of weed seed prior to leaving a weedy field.  This is done to prevent the spread of weeds from one field to another.

 
2.2.1.4.2 Fertilty Optimization

-Growers should adjust fertility applications on weedy fields to reduce weed growth
-Soil pH should be lowered, when possible, to reduce weed viability

 
  2.2.1.5 Biological Controls
 

Biological organisms that feed on weeds are encouraged. (ie. Chrysolinia beetle for St. John’s Wort)

3.2 Application of Fertilizers

       
 

3.2.1 Application

 

Applications rates are made based on nutrient levels from leaf tissue analysis, field health, plant height, disease pressure and weed pressure.

Perennia has link to an Agriculture and Agri-Food Canada factsheet on nutrient levels for blueberry leaves.

Click here for factsheet

Applications are made to optimize yield without causing excessive vegetative growth.

      back to top
 

3.2.2 Granular Fertilizers

 

Applications should be made when conditions are dry when vegetative growth has begun. Split applications can be beneficial.
-Growers must regularly calibrate fertilizer spreaders

      back to top
 

3.2.3 Liquid Fertilizers

 

There are many types of liquid fertilizers and these can be applied to the plants at many times of the year.
-Growers should ensure that the timing of application makes physiological sense for the plant to enhance production and allow for crop safety
-Growers must ensure that any liquid fertilizer and any other tank mix partner is compatible

      back to top
 

3.2.4 Alternative Amendments

 

There are many natural and alternative sources of nutrient amendments. Growers should ensure they know the nutrient content of those sources and that it is allowable as a nutrient amendment through the CFIA.
-Amendments in the crop year of production should not be animal based.
-Compost teas should be from plant based composts

      back to top
4.0 Field Management
   
 

4.1 Crop Monitoring

 

Growers regularly visit fields to observe crop development, pest levels and general plant vigour. 

Perennia has a fruit bud number counting video on it's You Tube channel.

4.2 Pruning

 

Pruning is a critical process, typically done in the mid to late fall after the harvest, or early spring the following year.  Pruning can be delayed by one year in fields that have good second crop potential.

The New Brunswick Department of Agriculture, Aquaculture and Fisheries has a useful factsheet on burning.
http://www2.gnb.ca/content/dam/gnb/Departments/10/pdf/Agriculture/WildBlueberries-BleuetsSauvages/A50E.pdf

      back to top
 

4.2.1 Mowing

 

Mowing is the least expensive way to prune a blueberry field.  Growers must maintain the mowers so that they operate optimally.  Flail mowers are the preferred mowing device.

The University of Maine, Cooperative Extension has a useful factsheet on pruning.
Click here for factsheet

Perennia has a mowing video on it's You Tube channel.

Mowing Methods in Wild Blueberries

      back to top
 

4.2.2. Burning

 

Pruning by burning is an expensive yet valuable process that is done selectively by the grower.  Burn pruning will prune stems to the ground encouraging new shoots from the rhizome, release nutrients for the plant, and reduce certain pest pressures.  Excessive burning will result in the reduction of soil organic matter and the decrease of plant health in certain soils.  Burning also has liability concerns that must be realized by the grower.

Burning permits are obtained from Nova Scotia Department of Natural Resources when required.
http://www.gov.ns.ca/natr/forestprotection/wildfire/burning-permits.asp
- Firebreaks are used when burning, including a controlled burn break done in early morning or late evening. Perimeter roadways should also be used.
-Mobile water tanks need to be at the ready when burning.
-Burning is not done in excessive winds.

      back to top
 
4.2.1.1 Oil/Propane Burning

This method uses a pull behind burner that uses either propane or home heating fuel to generate the flame and maintain heat.  This is often needed when conditions don’t allow the fire to spread on its own.

The University of Maine, Cooperative Extension has a useful factsheet on burning.
Click here for factsheet

back to top
4.2.2.2 Straw Burning

Straw is used as the fuel in this method, and placed on the field in late fall or early spring.  When conditions are right in the spring, the field is lit.  Typically the field is not mowed prior to laying down the straw.
Click here for factsheet

 
4.2.2.3 Sickle Bar/Burning

This method of burning is only done effectively on flat fields with good stem density and plant height.

Perennia has a useful factsheet on sickle bar mowing/burning.
Click here for factsheet

back to top
 

4.3 Soil Management

 

The soil is the medium in which the blueberry plants are grown.  Maintaining soil stability and soil structure is critical for long-term viability.  Since wild blueberries are a long-term perennial crop, there are few options to repair soil damage once it has occurred, therefore conservation is critical.

    back to top
 

4.3.1 Erosion Prevention

 

Soil conservation is a high priority in wild blueberry production
-Ground cover is maintained on slopes and soils with low levels of organic matter
-Broad spectrum herbicides are used sparingly on steep slopes or slopes that are prone to erosion.
-Mulches like sawdust, bark mulch and wood chips are used to stabilize bare areas

The New Brunswick Department of Agriculture, Aquaculture and Fisheries has a useful factsheet on the use of mulches.
http://www2.gnb.ca/content/dam/gnb/Departments/10/pdf/Agriculture/WildBlueberries-BleuetsSauvages/A80E.pdf

      back to top
 

4.3.2. Soil Compaction Prevention

 

Minimizing soil compaction is a major focus for blueberry growers
-Traffic across fields is limited to essential treatments
- Tramlines are used where practical (travelling on the same wheel tracks each pass)
- On fine textured soils that have high levels of clay and silt, driving tractors when soils are wet should be avoided.
- Driving should be avoided on saturated soils

      back to top
 

4.4 Waterway Protection

       
 

4.4.1 Buffer Zones

 

Buffer zones are maintained around waterways
-All pesticide labels are followed with respect to set-backs from waterways
-Drift reduction technology is used when spraying around waterways
- Vegetated strips are maintained between all fields and permanent waterways.

      back to top
 

4.5 Sensitive Area Protection (residential properties, other crops, etc.)

 

Great care is taken around sensitive areas
- All pesticide labels are followed with respect to set-backs from sensitive areas.
- Drift reduction technology is used when spraying around sensitive areas
- A good neighbor policy regarding communication and consultation is encouraged when dealing with sensitive areas.

      back to top
 

4.6 Refuge Areas

 

Areas are left around field edges and in non-productive to grow naturally and encourage native pollinators and other beneficial insects.
-Old rock fences and piles, old slash piles and native plants can encourage native pollinators.
-Hedge-rows will allow for a wind reduction and snow build-up on fields which will help with winter protection.  This is critical in some locations.  Hedge row height needs to be kept relatively low in order to keep shading impacts limited.

      back to top
5.0 Pollination

Pollination is critical to forming the fruit, therefore adequate pollinating units and how they are managed is critical to ensuring adequate yields.

The University of Maine, Cooperative Extension has a useful factsheet on Pollination
http://umaine.edu/blueberries/factsheets/bees/629-honey-bees-and-blueberry-pollination/

      back to top
 

5.1 Management During Bloom

 

Many disease and insect problems can occur near or during bloom.  Pesticide applications should always be treated as a last resort, but this is critically true before and during bloom.
-Insecticide applications during bloom should be avoided unless crop loss is expected.
-Fungicide applications during bloom are not ideal and should be avoided if possible. This is not always possible in fields that are prone to botrytis
- If making any pesticide applications during bloom, they should be made in the evening or when pollinators are not active.

      back to top
 

5.2 Managed Pollinators

 

Dalhousie University, Agriculture Campus through the Wild Blueberry Information Network and the University of Maine, Cooperative Extension have factsheets related to using managed pollinators.

      back to top
 

5.3 Attracting, Maintaining Wild Pollinator Populations

 

Native pollinators are encouraged in wild blueberry fields
-Native plants and a diverse habitat around a blueberry field will allow for more native pollinators. 
-Fields with large treeline perimeters tend to have more native pollinators.
-Larger fields can have a reduced diversity and number of native pollinators.

Dalhousie University, Agriculture Campus through the Wild Blueberry Information Network has factsheets related to managing native pollinators.

6.1 General Operation and Maintenance

       
 

6.1.1 Tractor-mounted

 
6.1.1.1 General Maintenance

Harvester are kept in good working order
-Harvesters are overhauled every season, with worn and damaged parts replaced
-During Harvest, machines are checked for damage and wear at the start of every day, with appropriate adjustments made
-Bent teeth, loose bolts, hydraulic leaks, skipping belts and worn brushes etc. are fixed or replaced immediately when they are noticed during harvest.

back to top
6.1.1.2 Harvesting

Great care is taken when driving a mechanical harvester
-The driver should constantly monitor the head and the pick line to make sure berries are not missed or lost out the front or back of the head.  Adjustments should be made in real time.
-Drivers should not take sharp corners while harvesting without lifting the head.

back to top
 

6.1.2 Alternative Harvesting Machines (ie. walk behind, sit on harvesters, etc.)

 

Great care is taken when operating harvesting machines
-Harvesters are overhauled every season, with worn and damaged parts replaced
-During Harvest, machines are checked for damage and wear at the start of every day, with appropriate adjustments made
http://perennia.ca/Fact%20Sheets/Horticulture/Fruit/Blueberry/Harvester_Demo_Comparison.pdf

      back to top
 

6.2 Hand Harvesting

 

Hand harvesting is typically used on hilly lands or for fresh fruit production, using a traditional hand rake.

-When raking, it is important the rake is slid into the plants below the lowest fruit and pulled up at an angle through the plant.
-Multiple sweeps through plants without dumping should be avoided.
-Buckets or pails should not be overfilled.
-Fields should be divided by rows when harvesting to ensure the whole area is picked.

      back to top
 

6.3 Berry Quality

 

6.3.1 Harvesting Conditions

 

Harvesting conditions greatly affect fruit quality.  Harvesting is done when conditions are close to optimal, whenever possible.
-Harvesting during rain should be avoided, especially when fields are wet
-Harvesting in extreme heat and humidity reduces berry quality and should be avoided if at all possible.
-Dry conditions below 20 degrees celcius are ideal for blueberry harvest.

      back to top
 

6.3.2. Limiting Foreign Material in Harvested Crop

 

Foreign material in harvested crop is avoided wherever possible
-Harvester heads are not run too low in developing fields or fields with course soils.

Berries are harvested and shipped in a way to minimize damage to the fruit.
-Berries should be shipped to the receiver or processors as soon after harvest as possible. (This becomes more critical as temperature and humidity increases)
-Shaking and vibration of full boxes or bins should be minimized during harvest and transport
-Bins and boxes should be inspected so they are free of debris and fully intact before being filled. (Damaged boxes lead to damaged fruit)
-Boxes or bins should be strapped, wrapped or contained during transport so they do not slide or shift
