It has been a cold spring these last few weeks for strawberries with slow growth, but we are starting to see buds and bloom. Fruit buds can be seen on June bearing varieties in early areas where row covers were used.
Planting has begun for day neutral strawberries. Overwintered day-neutrals are in bloom in early areas.
Two-spotted spider mite: Overwintering two-spotted spider mites (TSSM) can be found in some strawberry fields. Overwintering TSSM adults can be found on overwintering leaves, where they lay their eggs. Once new growth appears and the eggs hatch TSSM will spread throughout the plant to new growth. Scan the underside of leaves and use a hand lens to find TSSM.
Aphids: Prepare to apply an aphid spray once aphid eggs have hatched. Check for strawberry aphids on the underside of young, folded leaves (Figure 1 & 2). Cygon, Lagon, Beleaf and group 4s can be applied at this timing to control aphids.
Cyclamen mite: Keep an eye on your plants as they start to grow more quickly. Any cyclamen mite damage will become more apparent with variation in growth, as damaged plants will be stunted with crinkled, toughened leaves (Figure 3). Agri-mek and Vegol Crop Oil can be applied to control these mites. Agri-mek works best on cyclamen mite when plants are succulent and actively growing. Agri-mek needs to be applied with a non-ionic surfactant so be careful about using Captan, Maestro or Bravo in close timing to an Agri-mek spray. Beneficial mites may also provide some control. Avoid using group 3 products if you have a history of cyclamen mite problems, as group 3s are hard on natural predators.
Disease: Bravo or Echo can be applied at this time for botrytis control to reduce disease inoculum and help with disease management later in the season. Make sure to get these applications on before bloom with the 30-day PHI.
are looking good coming through the winter, and don’t seem to be delayed from the cooler weather.
Mummy berry: Blueberries can be infected with mummy berry shoot blight at the bud burst stage. Control for mummy berry beginning at bud swell through early bloom if there is a history of mummy berry on your farm. Mummy berry infections occur after 6 hours of rain or more depending on temperature. See the fungicide options in Publication 360B-Berries on page 34.
Use fungicides from different groups to control cane diseases such as phomopsis and anthracnose twig blight. Once bloom arrives, use fungicides that control both anthracnose and botrytis.
