Ano: 2013 URL: http://orgprints.org/28633/1/Muljar%20etal%202013.pdf Entomovektortehnoloogiast tuleneva lisatolmeldamise ja hahkhallituse tõrjumise efektiivsus aedmaasika sortidel ’Polka’ ja ’Sonata’ Organic Eprints Karise, Reet; Muljar, Riin; Mänd, Marika. Aedmaasikas on maailmas üks enam kasvatatavaid marjakultuure. Kuigi enamik aedmaasika Fragaria x ananassa sortidest on isetolmlemisvõimelised, aitab risttolmlemine kaasa suuremate ja kõrgema kvaliteediga viljade moodustumisele (Klatt jt., 2014). Puudulikult tolmeldatud õitest arenenud viljad on sageli ebakorrapärase kujuga ja väiksemad. Lisaks on hästi tolmeldatud viljad ka paremini värvunud, tugevama viljalihaga ning säilivad korjamisjärgselt kauem (Klatt jt., 2014). Aedmaasika põhiliseks kahjustajaks on hahkhallitus, Botrytis cinerea (Legard jt., 2000), mille tõrjumisel on sünteetiliste preparaatide kõrval osutunud efektiivseks ka mullaseen Gliocladium catenulatum. Selle seene eoseid ja hüüfitükke sisaldavat preparaati PrestopMix võib pritsida... Tipo: Conference paper, poster, etc. Palavras-chave: Crop health; Quality; Protection. Ano: 2014 URL: http://orgprints.org/28621/1/Karise%20etal%202014.pdf Sublethal effects of kaolin and the biopesticides Prestop-Mix and BotaniGard on metabolic rate, water loss and longevity in bumble bees (Bombus terrestris) Organic Eprints Karise, Reet; Muljar, Riin; Smagghe, Guy; Kaart, Tanel; Kuusik, Aare; Dreyersdorff, Gerit; Williams, Ingrid; Mänd, Marika. Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to the field in the context of entomovectoring are exposed to elevated risks because of sideeffects of those products. Here, we investigated with use of bumble bee workers of Bombus terrestris L. the lethal and sublethal effects of (i) pure kaolin, (ii) the biofungicide Prestop-Mix containing the parasitic fungus Gliocladium catenulatum and kaolin and (iii) the bioinsecticide BotaniGard containing the entomopathogenic fungus Beauveria bassiana and compared with wheat flour powder that we considered safe for bumble bees. As the most important result, treatment with... Tipo: Journal paper Palavras-chave: Crop health; Quality; Protection.

Ano: 2010 URL: http://orgprints.org/28625/1/Muljar%202010.pdf Bombus terrestris as an entomovector for suppressing Botrytis cinerea in open field strawberry Organic Eprints Mänd, Marika; Karise, Reet; Muljar, Riin. Strawberry (Fragaria x ananassa) is a fruit crop grown worldwide, but diseases such as the grey mould Botrytis cinerea frequently limit its yield. Most of grey mould infection on the fruits is initiated during the flowering period. Use of foraging bees as disseminators of microbial control agents (MCAs) to flowers is known as entomovector technology. Many researchers have shown that bumble bees can efficiently vector MCAs; however, most studies have been conducted in greenhouse conditions.

Ano: 2013 URL: http://orgprints.org/28649/1/M%C3%A4nd%20ja%20Karise%20Behaviour2013.pdf Meemesilase ja biofungitsiidi Prestop Mix kasutamine aedmaasika hahkhallituse tõrjes Organic Eprints Muljar, Riin; Mänd, Marika. The study was conducted in 2010 in five experimental areas of Tartu County. Honey bee hives were placed at the edge of strawberry fields at first bloom; each hive had a special dispenser attached containing the biofungicide Prestop Mix, which is a preparation of the parasitic fungus Gliocladium catenulatum. As the bees exited the hive through the dispenser, they were dusted with the Prestop Mix preparation and carried it to the strawberry field. Two treatments were established: 1) a bee-excluded untreated check (covered with exclusion cages), and 2) a bee-delivered Prestop Mix treatment. We compared the bee-disseminated treatment with the untreated check by counting the healthy and Botrytis-infected berries; we also compared strawberry varieties. Our...

Ano: 2014 URL: http://orgprints.org/28639/1/Karise%20et%20al_Eurbee%206_2014.pdf Bees as entomovectors and the biological control agent Gliocladium catenulatum J1446 Organic Eprints Muljar, Riin; Mänd, Marika. There is a need for more environmentally friendly plant protection methods, since the increasing use of agrochemicals has led to pesticide residues and resistance problems in the control of Botryrtis cinerea. An alternative to chemical spraying is to use bees as entomovectors to disperse biological control agents. Prestop Mix is a biofungicide that contains spores of the parasitic fungus Gliocladium catenulatum J1446, which has been successfully used in the control of B. cinerea. In 2010 we conducted a field experiment to study the efficiency of using bees in dispersing G. catenulatum in Estonian conditions. The study was carried out in two strawberry plantations of Tartu County, strawberry varieties were `Sonata` and `Polka`. Honey bee hives were placed...

Ano: 2011 URL: http://orgprints.org/28645/1/Muljar%20ja%20M%C3%A4nd%202011a.pdf The effect of biofungicide Prestop Mix on metabolic rate, water loss and longevity of bumblebee Bombus terrestris L. Organic Eprints Muljar, Riin; Karise, Reet; Veromann, Eve; Mänd, Marika. Prestop Mix is based on a natural soil fungus Gliocladium catenulatum J1446, which is applied to control fungal plant diseases. Bees can be used as vectors in carrying the biofungicide powder onto crop flowers; this has two benefits: pollination and plant protection from fungal pathogens. An important precondition is for the biopreparation to be safe for bees, therefore lethal and sublethal effects have to be tested. One way to assess sublethal effects of pesticides is to measure the metabolic rate (MR) and water loss rate (WLR) of an insect.

Mahepõllumajanduses on lubatud kasutada bakteritest, seentest ja viirustest valmistatud preparaate. Putukatõrjevahendina on laiemas kasutuses mullabakter Bacillus thuringiensis preparaat ning mullaseen Beauveria bassiana. Aedmaasika kasvatajatele on välja töötatud preparaat Prestop Mix, mis sisaldab mullaseene Gliocladium catenulatum Strain J1446 spoore ja mütseeli. See preparaat võitleb edukalt hahkhallituse vastu aedmaasikal ja aedvaarikal, samuti ka mitmetel köö- giviljadel ja isegi ilutaimedel. Taimedele või nende õitele kantavate preparaatidega puutuvad kokku ka paljud kasulikud organismid, näiteks tolmeldajad. Prestop Mix´i kandmiseks aedmaasika ja -vaarika õitele kasutatakse pulbri levitajatena just mesilasi: kimalasi või meemesilasi. Tarude...

Bumble bees can be used as vectors to distribute different powdery bioprepartions to control plant pest and diseases. The aim of the study was to test the safety of four powdery substances: wheat flour (used as negative control), bioinsecticide Botanigard 22 WP (based on entomopathogenic fungus Beauveria bassiana), biofungicide Prestop Mix (based on soil fungus Gliocladium catenulatum) and kaolin, which is an inert clay mineral used as carrier in Prestop Mix. The effect of those substances on the metabolic rate and water loss of bumble bee foragers after topical treatment was measured using flow-through respirometry.

Organic Eprints Muljar, Riin; Karise, Reet; Mänd, Marika. Hahkhallitus on aedmaasikal suuri saagikadusid põhjustav seenhaigus (Døving ja Mage, 2001; Williamson jt., 2007), mille tõrjumine keemiliste taimekaitsevahenditega on mahetootjale keelatud. Seetõttu on tekkinud vajadus alternatiivsete taimekaitsemeetodite järele, mis oleks loodust säästvamad ning sobiks ka kasutamiseks mahepõllumajanduses. Üheks selliseks alternatiiviks on entomovektortehnoloogia – biotõrje meetod, kus pulbrilisi biopreparaate viivad taimeõitele mesilaselaadsed putukad. Antud meetod sobib kasutamiseks õisi kahjustavate taimehaiguste ja -kahjurite tõrjel, kuna toitu (õietolmu, nektarit) otsides kannavad mesilased biopreparaadi täpselt aedmaasika õitele – see võimaldab vähendada preparaadikulu ning säästa keskkonda.

Hahkhallitus (Botrytis cinerea Pers.) on aedmaasikal (Fragaria × ananassa Duch.) suuri saagikadusid põhjustav seenhaigus, mille tõrjel sünteetiliste taimekaitsevahenditega ilmneb mitmeid negatiivseid kõrvalnähte nagu kiire resistentsuse kujunemine ning pestitsiidijääkide kogunemine viljadesse ja keskkonda, mistõttu on üha enam hakatud eelistama bioloogilisi tõrjemeetodeid. Üheks võimaluseks on viia biopestitsiid maasikaõiteni kasutades meemesilasi (Apis mellifera L.), nimelt lisatakse vastav pulbriline preparaat mesilastaru küljes olevasse dispenserisse, mida läbides jääb preparaat mesilase kehakarvade külge ja viiakse toidukorje käigus aedmaasika õitele.
