There have been conditions to cause an infection period detected at all weather stations currently deployed. Growers have reported their plants are at a susceptible stage and mature spore-producing cups are still be present in fields at this time. Most fields with mummy berry inoculum will have experienced an infection period overnight. If you have […]

There have been no infection periods in the last few days reported at the weather stations. While there has been fog reported in some fields over the last few nights, temperatures have been too low and the fog was not long enough for an infection period to occur. Mummy berry cups and pinheads are still […]

There were a few cups reported in Liberty and Appleton on Tuesday so I suspect there are cups present in this area too. You will need to check to see if your field […]

These will continue to develop with the rain we have been getting and I expect we will have […]

Growers in Liberty and Ellsworth have reported seeing pinheads in their mummy berry plots. The fungus is getting started before the plants this year. The plants are still not open or just getting started with only the very earliest clones being reported at F2 so far. With the warmer weather, flower buds will be getting […]

Infestation of fruit was found to be 6.4% in the Blue Hill Peninsula and only 0.5% in the Jonesboro area. If the weather warms […]

Average male trap captures ranged from nine to eleven per trap and total SWD ranged from 19 to 31 per trap. We also STARTED to find infested fruit. The percent infestation, where […]

Last week (August 19) SWD trap captures in both the Blue Hill and Jonesboro area remained stable with little change in adult captures compared to the previous week (Blue Hill = 10-20 flies/trap; Jonesboro = four to six flies/trap). As of last week, we have not detected any SWD in fruit samples. We will be […]

As of last week, there was still NO detectable SWD larval infestations in the fruit. We will be sampling the traps and […]

SWD adults are still being trapped in single numbers. This suggests that the population has not started to build yet, although it is anticipated that this might occur in the next seven-ten days. As of yet, we have NOT yet found any wild blueberry fields that have SWD infested berries, although blueberry maggots have been […]
