Fruit Spray Schedules for the Homeowner

Raspberries and blackberries

• Delayed dormant sprays
• Prebloom sprays
• Postbloom through harvest sprays

Raspberries and blackberries
Delayed dormant sprays

Apply when tips of buds show green.

Red-necked cane borers

A key pest
or pest complex

• Comments
  Characteristic injury is a swelling of the cane, about 3 inches long, with a splitting of the bark. Infested canes are weakened and often die. Remove and burn infested canes in early spring.

Anthracnose

A key pest
or pest complex

• Material
  liquid lime sulfur
• Comments
  Apply to canes when leaves are emerging from buds and before the blossoms open. This spray may damage the new leaves if they are longer than 0.75-inch long.

Raspberries and blackberries
Prebloom sprays

Apply when blossom buds first appear through when flowers show white.

Red-necked cane borer

A key pest
or pest complex

• Material
  pyrethrins and rotenone
• Comments
  See comments in "delayed dormant" section. Adult beetles typically appear when flowers show white. Newly formed swellings can be seen in July and August.
  Apply insecticide when bloom begins and again 7 to 14 days later. Direct spray to lower part of the primocane and avoid spraying the blossoms.

Raspberry crown borer

• Material
  pyrethrins and rotenone
• Comments
  Infested canes become spindly, lack vigor and often break off at ground level. Remove and destroy weakened or infested canes. Drench crown and lower 2 feet of cane with insecticide.

Raspberry fruitworm

• Material
  carbaryl
  or esfenvalerate
  or methoxychlor
  or neem
  or pyrethrins and rotenone
• Comments
  Grubs tunnel into the center of the fruit to feed, may cause premature fruit drop. Adult beetles feed on foliage resulting in the leaves being skeletonized. Early developing fruit is more at risk than later developing varieties. Apply insecticide when blossom buds first appear and then again before the blossoms open.
  Neem (azadirachtin) is a botanical insecticide.

Blackberry psylla

• Material
  esfenvalerate
• Comments
  Feeding damage causes tightly curled leaf clusters. Such leaf clusters should be removed and destroyed immediately. Apply insecticide when this damage first appears (or first notice of adults).

Tarnished plant bug

• Material
  malathion
  or esfenvalerate
  or permethrin
  or insecticidal soap
• Comments
  Damaged berries are malformed, and the whitening of a damaged druplet occurs when mature fruit are attacked. If needed, apply sprays just before the blossoms open and then again when the fruit start to color.
  Controlling weeds in and around the planting helps to reduce tarnished plant bug populations.

Raspberries and blackberries
Postbloom through harvest sprays

Tarnished plant bug

• Material
  malathion
  or esfenvalerate
  or permethrin
  or insecticidal soap
• Comments
  See comments in "pre-bloom spray" section.
  Apply every 14 days after petal-fall as needed.

Japanese beetle, green June beetle, rose chafer, sap beetles

• Material
  carbaryl
  or methoxychlor
  or malathion
