“…The fungicides evaluated in this study represent a broad range of chemistries and modes of actions. Two of the nine fungicides tested are in the QoI class (azoxystrobin and famoxadone), and these compounds are known to be highly active against several species of Colletotrichum, including C. acutatum (Wedge et al 2007). In other studies, fungicides (chlorothalonil, pyraclostrobin + boscalid) reduced anthracnose disease severity and incidence, and azoxystrobin in rotation with maneb (no longer labeled) was not as effective compared with some of the other treatments but the application regimes used were more consistent with resistance management guidelines (Lewis-Ivey et al 2004) .…”

“…Copper compounds such as copper hydroxide are often tank-mixed with mancozeb for control of bacterial spot on pepper and when applied separately, copper or mancozeb formulations can be used for control of anthracnose. The fungicide mix fludioxonil plus cyprodinil (Switch 62.5WG, Syngenta Crop Protection, LLC, Greensboro, NC, USA) was effective against anthracnose caused by C. acutatum on strawberry (Wedge et al 2007) but it is not currently labeled on pepper. Difenoconazole premixed with cyprodinil (Inspire Super 67.5WP, Syngenta Crop Protection) and famoxadone plus cymoxanil (Tanos 50DF, E.I.…”

Management and cross-infectivity potential of Colletotrichum acutatum causing anthracnose on bell pepper in Florida

et al. 2013

Early anthracnose caused by Colletotrichum acutatum has become an increasingly serious disease on green, unripe bell pepper fruit in Florida. This contrasts with earlier reports of anthracnose occurring on bell pepper primarily as a ripe-rot disease of mature, colored pepper fruit caused by Colletotrichum gloeosporioides. Management of anthracnose on green bell pepper fruit using fungicides and a commercial inducer of systemic acquired resistance, acibenzolar-S-methyl (ASM), was evaluated during three seasons. In two of the three trials, all the fungicides tested including azoxystrobin, fludioxonil + cyprodinil, mancozeb, famoxadone + cymoxanil, copper hydroxide, and ASM significantly increased the number of marketable fruit compared with control plants. These trials identified fungicides that could contribute to a successful pest management program on pepper for controlling anthracnose caused by C. acutatum. The cross-infectivity potential of C. acutatum was investigated on tomato and strawberry by in vitro and field inoculation. Anthracnose lesions formed readily on wound-inoculated detached fruits of all hosts in in vitro assays. Under field conditions, after inoculation, anthracnose lesions occurred on pepper fruit but no lesions of anthracnose were found on either ripe or unripe tomato or strawberry fruit in adjacent plots.

Aunque entre los fungicidas usados con frecuencia se encuentran los de efecto preventivo como captan, thiram y diferentes formulaciones a base de cobre, aquellos de modo de acción específi-ca se aplican con frecuencia para el manejo de esta enfermedad, entre ellos el ciprodinil+fludioxonil, pyraclostrobin, azoxystrobin y metil tiofanato (Turechek et al, 2006;Wedge et al, 2007). El modo de acción específica y el uso frecuente de estos fungicida implican riesgo para el desarrollo de resistencia en los hongos por lo que deben ser utilizados bajo ciertos principios para un manejo efectivo de la resistencia como son la dosis correcta, número de aplicaciones, mezclas del modo de acción, alternaciones y los tiempos o momentos de aplicación (van den Bosh et al, 2014).…”

<p>El objetivo de este estudio fue determinar la sensibilidad de Colletotrichum acutatum a los fungicidas metil tiofanato y azoxystrobin, basada en el crecimiento de micelio y germinación de conidios. Se evaluaron 60 aislados monoconidiales de dos regiones productoras de fresa del estado de Michoacán, en medio de cultivo enmendado con 0.001, 0.01, 0.1, 1 y 10, 100 y 2000 µg mL-1 de fungicidas. La dosis efectiva que redujo en un 50% el crecimiento micelial (DE50) del metil tiofanato varió de 0.28 a 9.72 µg mL-1 en el valle de Maravatío y de 1.39 a 2.99 µg mL-1 en el valle de Zamora. En conidios la DE50 varió entre 0.9 a 396.4 µg mL-1 en el valle de Maravatío y de 0.43 a 63.32 µg mL-1 en el valle de Zamora. Para el azoxystrobin las DE50 en micelio variaron de 0.04 a 0.36 µg mL-1 en Maravatío y de 0.07 a 0.99 µg mL-1 en Zamora. En conidios las DE50 variaron de 0.01 a 0.56 µg mL-1 para Maravatío y 0.006 a 0.15 µg mL-1 en Zamora. Las distribuciones de las DE50 indicaron que los aislados de C. acutatum fueron sensibles al azoxystrobin y moderadamente resistentes al metil tiofanato.</p>

Progress in Food Preservation

View full text Add to dashboard Cite

The safety and management of food during its processing, transport and storage are prerequisites for modern food processing. Despite the worldwide development of new ranges of preservation techniques, the microbiological safety of meat, fruits and vegetables, as well as dairy products, continues to be of major concern to both consumers and the food industry. Several outbreaks of foodborne pathogens during the last two decades have focused public attention on food safety. Environmental and human health concerns with regard to current practices involving synthetic compounds have further compelled the food industry to develop improved strategies. Natural products have been investigated as alternative biocides and antioxidants in an effort to rule out the use of synthetic preservatives, which are regarded as detrimental to health and the environment. Various applications of essential oils and plant extracts as natural antioxidants and antimicrobial agents have been reported and the use of such extracts have been validated by many researchers in several countries. This chapter describes the use of essential oils and other plant extracts as food preservatives, with emphasis on the fruit and vegetable post-harvest environment. The antifungal effects of these extracts on the control of fruit and vegetable pathogens are covered in detail. In addition, the application of plant extracts in the control of bacterial biofilms, which are more resistant than their planktonic counterparts to therapeutic intervention such as antibiotics, is also summarized. Finally, an overview regarding the importance of medicinal indigenous plants from developing countries as natural biocides and antioxidants is provided.
