Soil Nutrient Management and Cultural Practices
- Bog and ditch areas are properly managed to maximize drainage. All
areas of the
bog are capable of being flooded for proper winter protection. 20 pts - Trash is removed yearly from the bog by flooding. 10 pts
- Trash from border areas is removed to prevent spread of plant disease. 10 pts
- Bog is sanded at regular intervals. 10 pts
- Bog is periodically held under a late water flood as an alternative
strategy to
reduce fruit rot or infestations of mites, Gypsy moths, false armyworm or
cranberry fruitworm. 10 pts - Flumes are maintained to maximize tightness and minimize leakage. 10 pts
- Bog has been managed to reduce overgrowth and to promote air circulation. 10 pts
- Leaf tissue analysis, including nitrogen, is performed at least every two years. 5 pts
- Fertilizers are applied utilizing the previous year's leaf tissue
analysis as well as
other appropriate crop and weather related factors. 5 pts - Records of fertilizer applications are kept. Abnormalities and response applications are noted as needed. 10 pts
- Fertilizers are applied in a program using approved materials in accordance
to their
respective uptake and mobility properties. 10 pts

Pesticides Application and Records
Only pesticides approved and registered in the state are used. Sprinkler
systems must meet federal chemigation standards. Records of pesticide applications
including date, field identification, targeted pest, pesticide name, formulation,
rate and number of acres treated are maintained. Where bogs intersect rivers
or where there is no water holding capacity, diazinon, azinphosmethyl (GUTHION™),
chlorpyrifos (LORSBAN™) and chlorothalonil (BRAVO™) are not used
in the bog. Pesticide drift is minimized. Re-entry and pre-harvest intervals
are adhered to.
- If a scout or consultant is employed, a specific scout safety program is followed. 10 pts
- In cranberry farms where multiple management units exist, records of monitoring data and pesticide applications are kept separately for individual bogs or management units. 10 pts
- Records of dates of holding-water within the farm system after pesticide applications are maintained. 5 pts
- Chemigation system gives complete coverage of bog. 10 pts
- Spraying of sensitive areas is prevented by half-heads or spray guards where necessary. 10 pts
- Chemigation system includes gate valves to allow for partial treatment of system. 10 pts
- Chemigation system is operating at its optimal Coefficient of Uniformity. 10 pts

Disease Management
- Crop stages are recorded at least weekly from scattered bloom onward. 5 pts
- Percent bloom counts are used to time fungicide applications. 5 pts
- Fungicide applications are made according to Extension recommendations. 5 pts
- When a disease is suspected, vine samples are collected and brought
to an
appropriate laboratory for diagnosis. 10 pts - Irrigation is routinely scheduled to minimize the available infection
period for fruit
rot fungi. 10 pts

Insect Management
Insect monitoring conforms to those practices described by the state
IPM recommendations. Records of all monitoring information collected are
maintained.
- Sweep samples are taken weekly from early May through scattered bloom
to
monitor for presence and abundance of insect pests, as appropriate for any
individual management unit. 25 pts - Insecticide applications are applied only when supported by appropriate
monitoring
and when action thresholds are exceeded. 25 pts - Where the cranberry girdler is a frequent pest, treatments are timed
to
pheromone trap captures. *5 pts - Where the blackheaded fireworm is a frequent pest, treatments are
timed to
pheromone trap captures. *5 pts - Where the Sparganothis fruitworm is a frequent pest, treatments are
timed to
pheromone trap captures. *5 pts - Populations of susceptible lepidopteran pests that exceed recommended
action
thresholds are managed with application Bacillus thuringiensis products. 10 pts - Cranberry fruitworm management is based upon the phenology of the
cranberry
plant. Fruit are inspected at regular recommended intervals. Subsequent treatment
is made when the number of unhatched viable eggs exceeds the action threshold. 10 pts - Where cranberry girdler is a frequent pest, alternative management
techniques
such as sanding, September flooding or entomophagous nematodes are used. *10 pts - No insecticides are applied for cranberry tipworm. 10 pts

Weed Management
- A weed survey map is made before harvest. 10 pts
- Weed management, including herbicide selection and rates, is determined using the previous year's weed survey. 10 pts
- Non-chemical weed management techniques, such as hand-pulling woody perennials or clipping annual weeds, are utilized. 5 pts
- Where appropriate, spot treatment of weed area is used instead of broadcast treatment of bogs. *10 pts
- A mowing program is followed to reduce weed seed populations on ditch banks. 10 pts
- Where dodder is a frequent pest, pre-emergence herbicide applications are made in response to dodder seedling emergence. *10 pts
- If dodder is a frequent pest and fruit is harvested in water, booms are cleaned and rinsed between harvested units to minimize seed transport. *10 pts
- The UMass Extension weed priority system is utilized to assist in the formulation of a weed management program. 10 pts
