“…Models to predict conditions for B. cinerea infection in grapes, which are based on environmental conditions (Broome et al, 1995;González-Domínguez et. al., 2015;Kim et al, 2007;Nair and Allen, 1993;Shtienberg, 2004;Shtienberg and Elad, 1997) and inoculum concentration and their dynamics (Carisse et al, 2014;Fernández-González et al, 2012), have been developed and proposed to predict the risk of GM infection. For example, Broome et al (1995) developed a predictive model to determine the risk of B. cinerea infection on grapes.…”

by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the main control strategy. These control measures can be used to reduce the initial inoculum or to lower the disease infection rate. However, control measures that reduce the infection rate are the most effective means of controlling GM. Important progress toward understanding the complexity of the biology and epidemiology of this pathogen has occurred in recent decades. This has allowed the improvement and development of more effective and sustainable control strategies against B. cinerea. This review article provides a recent update regarding grape GM, with special emphasis on Chilean production conditions.

“…2) To reduce fungicide usage, the biological control of B. cinerea is being evaluated in several crops. [3][4][5][6][7] A promising biocontrol agent is the fungus Clonostachys rosea (Link: Fr.) Schroers, Samuels, Siefert & Gams (Fungi, Ascomycota, Hypocreales, Bionectriaceae), which has suppressed B. cinerea sporulation in many plant species.…”

Sensitivity of four isolates of <i>Clonostachys rosea</i> to pesticides used in the strawberry crop in Brazil

et al. 2012

e sensitivity of four isolates of Clonostachys rosea, potential biocontrol agents of Botrytis cinerea, to fungicides, insecticides, and herbicides used in the strawberry crop was evaluated in vitro. All fungicides inhibited mycelial growth and conidia germination of all isolates. e insecticides decreased both as well, although less intensely than the fungicides did. e herbicides were the least toxic. Suitable spraying intervals of fungicides and usage of compounds less toxic to C. rosea are crucial to successfully manage strawberry gray mold.

The effect of temperature (15, 20, 25 and 28 °C), wetness period (0, 6, 12, 24, 48 and 72 hours) and conidia concentration (0, 1x10 2 , 1x10 3 , 1x10 4 , 1x10 5 and 1x10 6 conidia/mL -1 ) on the incidence and severity of gray mold caused by Amphobotrys ricini in castor bean (Ric inus communi s) b unch es were evaluated. The c onid ia concentration effect was evaluated fixing the temperature at 25°C and the wetness duration at 48 hour. The temperature and wetness duration were evaluated fixing the conidial concentration at 1x10 5 conidia mL -1 . The plants were evaluated as to the incidence of fruit wiht symptons and severity in each bunch. progress curve (AUIPC) and under severity progress curve (AUSPC) was calculated, and the results submitted to variance and regression an alys is. There wa s a signifi cant difference for the different concentrations of conidia, for the temperatures and for the wetness period. There was significant interaction between temperature and the wetness period. With the increased concentrations of conidia, both the incidence and the severity of the gray mold showed increases until the 10 5 conidia mL -1 concentration. There was an increase of AUIPC and AUS PC for the wetn ess period inc reas e a nd t he temperature. There were no symptoms in the absence of wetness.(AACPI) e da severidade (AACPS) e os dados submetidos à análise de variância e regressão. Houve diferença significativa quanto à influência de diferentes concentrações de conídios, temperaturas e períodos de molhamento no progresso do mofo-cinzento-da-mamoneira, além de ocorrer interação significativa entre a temperatura e o período de molhamento. A incidência e a severidade do mofo-cinzento-damamoneira apresentaram acréscimos com a elevação da concentração de conídios até 10 5 conídios mL -1 . A AACPI e a AACPS aumentaram com o incremento do perí odo de molh amento e eleva ção da temperatura. Não houve manifestação de sintomas na ausência do molhamento foliar.O cultivo da mamoneira (Ricinus communis L.) expandiu-se impulsionado pelo programa nacional de biocombustíveis. Contudo, em algumas regiões onde o período de chuvas prolongadas e temperaturas amenas coincidem com a época de florescimento da mamona e o início da frutificação, foram constatadas perdas severas causadas pelo mofo-cinzento (Amphobotrys ricini [Buchw.] Hennebert) (17). Esse patógeno infecta o racemo em qualquer fase de seu desenvolvimento, encobrindo-o totalmente com micélio e esporos, conferindo-lhe um aspecto pulverulento cinza.Inicialmente, o fungo foi descrito como Botrytis ricini Godfrey e seu teleomorfo foi denominado de Sclerotinia ricini Godfrey (10). O gênero foi modificado por Whetzel para Botryotinia e Hennebert estabeleceu o novo gênero Amphobotrys para acomodar a forma conidial semelhante à Botrytis de B. ricini (11). O gênero Amphobotrys possui uma única espécie típica, A. ricini (Buchw.) Hennebert.A doença caracteriza-se pelo apodrecimento dos frutos nos cachos da mamoneira, principalmente sob alta umidade relativa. Em patossistemas q...
