Carbohydrate Model for May 5, 2015
May 5, 2015Full bloom came on extremely rapidly across the state over the past few days. Prior to this weekend most areas of the state were a little behind the normal timing of flower development. However, the warm temperatures of the weekend across the entire state pushed flower development.
Disease Update: Scab Infection Period Predicted for May 5 - 6
May 4, 2015A weather system moving East will be bringing rain Tuesday into Wednesday. At the same time we are experiencing the peak period for dispersal of mature scab spores. The predictive models indicate May 5 - 6, 2015 will be a scab infection period. Growers need to protect trees to prevent scab infection during this critical period.
Weekly Insect Bytes - Install Pheromone Dispensers this Week
May 4, 2015Brown marmorated stink bug adults are slowly emerging from their overwintering shelters. The five percent egg hatch of Oriental fruit moth (and the optimal timing to start controlling OFM) is expected around May 7th in the Biglerville area. All pheromone traps for monitoring fruit pests except traps for obliquebanded leafroller (OBLR) and peach tree borer (PTB) should already be placed in orchards.
Disease Update: Fire Blight Alert This Week
May 3, 2015All predictive models indicate a high risk for fire blight infection this week due to the high temperature, humidity, and chance of rain showers in the forecast. Growers should begin protecting blossoms with streptomycin on Monday. More strep applications will be needed as infection conditions persist.
