Use traps baited with apple cider vinegar plus ethanol alcohol (90% apple cider vinegar plus 10% ethanol) and/or fermenting yeast, grape juice, or yellow sticky cards with a commercial lure; or purchase commercially available traps and lures to monitor populations.
Keep planting clean of over-ripe fruit.

Spray once SWD adults are captured and fruit begins to turn color, or when 1st larva found in fruit.
For resistance management do not make more than 2 sequential applications of insecticides in the same IRAC group. Success is labeled for Maine, New Hampshire only
Venerate XC is suppression only

Keep planting free of weeds.
Action threshold for nymphs or adults is when 10-20% of canes are infested. Adults migrate to fruit when adjacent fields are mowed. |
Apply pre-bloom if adults found in planting, but avoid insecticide spays during bloom.
Apply sprays in evening. |

Space rows at least 8 feet apart, prune canes to a density of 3 to 4 canes per sq. ft. to improve air circulation.
|
Apply at 5% bloom and again at full bloom. Repeat application only if weather is wet.
Overuse of any single materials may result in the development of resistance in the fungus. EcoSwing is labeled for raspberry and blackberry. When applying EcoSwing use a minimum of 10gal water/A for ground applications. See label for additional application methods. 4hr REI.
BotryStop: Do not use a stomatal flooding or penetrant adjuvant.

Predatory mites may help.
Avoid use of pesticides which will kill natural enemies of mites such as carbaryl or bifenthrin. Avoid excess Nitrogen which can lead to higher mite populations. |
Sulfur (80% WP) applied at 5-10 lb/100 gal for powdery mildew will provide some suppression.
Do not use M-Pede within 3 days of a sulfur application. Magister SC, Onager OPTEK and Zeal may only be applied once per year. Acramite is limited to 2 applications per season. Add adjuvant to Grandevo

Plant only in well-drained soils.
Planting on raised beds also significantly reduces Phytophthora incidence. Black raspberry cultivars are generally least susceptible to this disease.
Red raspberries ‘Prelude’, ‘Anne’ ‘Latham’, ‘Nova’, ‘Boyne’, ‘Josephine’, ‘Caroline’, ‘Jaclyn’. ‘Moutere’ and ‘Killarney’ appear to be the most resistant red cultivars.
|
Apply Ridomil in 3 ft wide band over the row in early fall; repeat in early spring before growth begins.
Apply Aliette and Phostrol in sufficient water to thoroughly wet the foliage. Begin foliar sprays in the spring when new growth is 1-3" and continue spraying on a 45-60 day schedule up to a maximum of 4 sprays during the growing season.
Note long PHI (60 days) for Aliette .
Apply Actinovate as a soil drench. Since Actinovate contains live spores of a microbe, best results will be obtained if used prior to disease onset.
RootShield PLUS - cutting or barerooted transplant dip use 6 oz/20 gal water
