W latach 2017–2018 prowadzono badania dotyczące wy-stępowania chorób powodowanych przez grzyby na czterech plantacjach borówki wysokiej zlo-kalizowanych w centralnej Polsce. Celem badańbyła izolacja i identyfikacja patogenów z pora-żonych organów krzewów borówki wysokiej. W badanym materiale roślinnym zidentyfikowano cztery gatunki grzybów. Na wszystkich lustrowa-nych plantacjach obserwowano Botrytis cinerea, Godronia cassandrae i Phomopsis vaccinii, a tyl-ko na jednej plantacji zidentyfikowano Valdensia heterodoxa. Grzyby identyfikowano na podstawie oznak etiologicznych obecnych na porażonych organach roślin, przy użyciu klasycznych metod. W ramach badań oceniono skuteczność siedmiu fungicydów w zwalczaniu choroby szara pleśńborówki wysokiej. Do badań wykorzystano za-równo preparaty powszechnie polecane w ochro-nie borówki wysokiej przed szarą pleśnią, jak i fungicydy dopuszczone do ochrony przed tą cho-robą upraw innych roślin jagodowych (truskawka i malina). Fungicydy Luna Experience 400 SC i Prolectus 50 WG mogą być rozważane jako uzu-pełnienie listy środków zalecanych do zwalczania choroby szara pleśń na plantacjach borówki wy-sokiej.

<i>Fusicoccum</i> canker of highbush blueberry was first detected in 1973 in Poland. The diseases appeared on the shoots of variety Jersey in the collection of the Department of Pomology, Agricultural University, Warsaw-Ursyn6w. The disease was caused by the fungus <i>Godronia cassandrae</i> f. <i>vaccinii</i> {Peck.) Groves. The conidial stage is known as <i>Topospora myrtilli</i> (Felfch.) Boermema syn. <i>Fusicoccum putrefaciens</i> Shear.

Godronia Cassandrae

Some histological changes were observed in blueberry stems infected by the fungus <i>G.cassandrae</i>. Dead cells of subepidermal collenchyma and cortical parenchyma filled with brown flocculent deposits were seen in the lesion areas. Pycnidia characteristic for the conidial stage of the fungus (<i>Topospora myrtilli</i>) were found in the collenchyma layer. The diseased tissues were found to be separated from the healthy ones by a layer of cork cells which was initiated under the epidermis and ended under the pericycle. Beneath this cork layer lamellar collenchyma and collenchyma-like phelloderma formed. Similar histopathological changes were observed in blueberry stems infected by seven other fungi.

Samples of ripe fruit were taken at harvest from all eight commercial cranberry farms in Michigan over a 3-year period to determine the distribution and incidence of fruit rot diseases and the fungal pathogens associated with rotted fruit. Totals of 23, 33, and 28 beds were sampled in 1999, 2000, and 2001, respectively. Fruit rot incidence varied widely among beds and farms and ranged from 5 to 97% (mean 33.4%) in 1999, 1 to 91% (mean 26.3%) in 2000, and 1 to 67% (mean 12.8%) in 2001. Differences in fruit rot incidence were observed among cultivars, but rankings differed among farms. In general, cultivars Ben Lear, Bergman, and Pilgrim tended to have lower and Beckwith and WSU61 higher fruit rot incidence than other cultivars grown in the same location. Colletotrichum acutatum, Pestalotia vaccinii, and Phyllosticta vaccinii were the fungi most frequently recovered from rotted fruit. Fusicoccum putrefaciens, Phomopsis vaccinii, Physalospora vaccinii, Allantophomopsis lycopodina, Coleophoma empetri, and Botrytis cinerea were isolated occasionally in 1999. The isolation frequency of Physalospora vaccinii, Phomopsis vaccinii, and C. empetri increased markedly in 2000. Glomerella cingulata was first detected in 2001. Fusicoccum putrefaciens was most common in the northern and Glomerella cingulata in the southern growing areas. A comparison of sound and rotted fruit from selected beds showed that Phyllosticta elongata predominated in sound fruit, whereas G. cingulata predominated in rotted fruit.

One-year-old rooted microshoots and 2-year-old rooted hardwood blueberry cuttings (Vaccinium corymbosum L.) were inoculated with Phomopsis vaccinii Shear using stem flap, stem freeze, needle pierce, and leaf tear wounding techniques. The needle pierce was the simplest method that produced high infection rates. Nine northern-adapted cultivars were placed in a factorial experiment to measure their infection resistance. Microshoots and hardwood cuttings of `Elliott' and `Bluetta' survived the longest and had the lowest mortality rate. Phomopsis vaccinii was reisolated successfully from inoculated shoots of all cultivars.

Infestations of Botrytis blossom blight (Botrytis cinerea) can reduce yields in commercial blueberry fields in the Pacific Northwest. In 1993, environmental conditions during blueberry flowering were ideal for the development of Botrytis. Individual plants were evaluated in a replicated highbush blueberry culture/advanced selection trial (42 clones, 5 reps, 3 plants) in Aurora, Ore. Each plant was evaluated for damage due to Botrytis using a subjective scoring system (1= all flower clusters on plant appear blighted, 5= many blossoms blighted, 9= no blossoms blighted). Many clones showed very little injury. The following clones showed the greatest injury, in decreasing order of severity, NC 2678, `Bluechip', `Bounty', G-805, `Nelson', G-224, `Berkeley', `Sierra', and `Bluegold'. In addition, Botrytis damage was scored on the field collection of Vaccinium at the National Clonal Germplasm Repository. Data from this nonreplicated study will also be presented.
