Ash dieback mortality and damage at the Botanic Garden Meise, Belgium

Four 10m × 10m plots were laid out in the naturally regenerating woodland at the Botanic Garden Meise (WGS84: 50° 55ʹ 37ʺ N, 4° 19ʹ 18ʺ E; 50° 55ʹ 37ʺ N, 4° 19ʹ 17ʺ E; 50° 55' 38.6" N 4° 19ʹ 21ʺ E; 50° 55ʹ 39ʺ N, 4° 19ʹ 29ʺ E). They were selected because the areas contained a large number of ash saplings. Within these plots all ash seedlings greater than 40 cm tall were labelled with a small (2 cm × 4 cm) plastic tag attached with stretchable plant tie. Each tag was engraved with a unique number so that the tree could be identified. These plots were not intended to be replicates but just a convenient method of refinding the tagged trees. In the first year either the height or the girth of the tree was measured with a tape measure, depending upon whether the tree was small enough to measure the height. In the first year and each subsequent year each tree was scored for the apparent damage caused by ash dieback (Hymenoscyphus pseudoalbidus). The same scoring scheme was used as that by Pliūra et al. (2011). This is a 5 point system where 1 is a dead tree; 5 is an undamaged tree and 2–4 are progressively less damaged trees. The plots were laid out on 14 April 2013. In 2014 plots 1 and 2 were scored on 14th April  and plots 3 and 4 on 21st April. In 2015 plots 1 and 2 were scored on 6th May and plots 3 and 4 on 30th April.

Can the botanical azadirachtin replace phased-out soil insecticides in suppressing the soil insect pest Diabrotica virgifera virgifera ?

Can the botanical  azadirachtin replace phased-out soil insecticides in suppressing the soil insect pest Diabrotica virgifera virgifera ? Background Due to recent bans on the use of several soil insecticides and insecticidal seed coatings, soil-dwelling insect pests are increasingly difficult to manage. One example is the western corn rootworm (Diabrotica virgifera virgifera, Coleoptera: Chrysomelidae), a serious root-feeder of maize (Zea mays). We investigated whether the less problematic botanical azadirachtin, widely used against above-ground insects, could become an option for the control of this soil insect pest. Methods Artificial diet-based bioassays were implemented under standard laboratory conditions to establish lethal dose curves for the pest larvae. Then, potted-plant experiments were implemented in greenhouse to assess feasibility and efficacy of a novel granular formulation of azadirachtin under more natural conditions and in relation to standard insecticides. Results Bioassays in three repetitions revealed a 3-day LD50 of 22.3 µg azadirachtin per ml which corresponded to 0.45 µg per neonate of D. v. virgifera and a 5-day LD50 of 19.3 µg per ml or 0.39 µg per first to second instar larva. No sublethal effects were observed. The three greenhouse experiments revealed that the currently proposed standard dose of a granular formulation of 38 g azadirachtin per hectare for in-furrow application at sowing is not enough to control D. v. virgifera or to prevent root damage.  At 10x standard-dose total pest control was achieved as well as the prevention of most root damage. This was better than the efficacy achieved by cypermethrin-based granules and comparable to tefluthrin- granules, or thiamethoxam seed coatings. The ED50 for suppressing larval populations were estimated at 92 g azadirachtin per ha, for preventing heavy root damage 52 g /ha and for preventing general root damage 220 g /ha. Conclusions There seems clear potential for the development of neem-based botanical soil insecticides for arable crops such as maize. They might become, if doses are increased and more soil insecticides phased out, a promising, safer solution as part of the integrated pest management toolkit against soil insects.

Catalogue of Plants 2021. Royal Botanic Garden Edinburgh (data)

This is a static snapshot of the Royal Botanic Garden Edinburgh (RBGE) Living Collection Catalogue held in the Living Collections Management System (CMS) it is produced as a record of what was being grown at the RBGE on 10/09/2021.  The data includes the specialist gardens of Benmore Botanic Garden (BBG), Dawyck Botanic Garden (DBG), Logan Botanic Garden (LBG), Sites of the  International Conifer Conservation Programme (ICCP) and the Scottish Native Plants Project. The dynamic (up to date) data available at <a href="https://data.rbge.org.uk/search/livingcollection/">https://data.rbge.org.uk/search/livingcollection/</a>   How to Use the Catalogue Spreadsheet By Benedict Lyte The catalogue is divided into nine sections: <ol> <li>Bryophytes</li> <li>Fern allies</li> <li>Ferns</li> <li>Gnetophytes</li> <li>Conifers</li> <li>Ginkgophytes</li> <li>Cycads</li> <li>Dicotyledons</li> <li>Monocotyledons</li> </ol>   The listing is organised alphabetically by family following APGIV (<a href="http://www.mobot.org/MOBOT/research/APweb">http://www.mobot.org/MOBOT/research/APweb</a>) and then accession number. The taxon data uses World Flora Online (<a href="http://www.worldfloraonline.org">http://www.worldfloraonline.org</a>) for verification.   Accession number RBGE accession numbers are eight digits long: the first four digits represent the year of the accession and are followed by the sequential number of that accession in that year.   The location where the accession is alive BBG = Benmore Botanic Garden DBG = Dawyck Botanic Garden InvI = Inverleith, under glass InvO = Inverleith, outdoors LBG = Logan Botanic Garden Ext = External site that is part of the International Conifer Conservation Programme or the Scottish Native Plants Project   Country of origin Names of the countries follow those given by the International Organization for Standardization standard 3166 (ISO, 2011).   Collection info Collection ID is a code allocated by RBGE. Collector is the name(s) of the individual(s) on the collection trip with that ID. Collection number is the number assigned to the accession when it was collected.

FloraNER: a Named Entity Recognition Dataset for Botanical French Text

FloraNER is a Named-Entity Recognition (NER) dataset for botanical french literature. The dataset covers plant species names and plant morphological terms for both plant organs/characteristics and their descriptors. the descriptors are annotated both in a coarse-grained manner as the named entity type "DESCRIPTOR" and in a fine-grained manner, categorized into the following named-entity types: Form, Measure, Surface, Color, Position, Disposition, Structure, and Development. FloraNER is distantly annotated using a specialized botanical corpus. Consequently, it's important to note that not all named entities within the text are captured and annotated for the coarse-grained and fine-grained datasets.
