Control of Monilinia spp. and Rhizopus spp. in stone fruit using new strategies during the harvest
Control de Monilinia spp. y Rhizopus spp. en fruta de hueso mediante nuevas estrategias que no dejen residuos en el momento de la cosecha
Context
Catalonia is a leading international producer of stone fruit (Prunus persica (L.) Batsch), with a total output of 406,279 tonnes. Brown rot due to Monilinia spp. is the main disease affecting stone fruit in our area of production. Rhizopus spp. is another of the major pathogens that affect stone fruit, causing soft rot, and its prevalence in our area of production has increased in recent years.
Despite the incidence of stone fruit affected by soft rot, no reliable information is currently available on the effectiveness of fungicides on stone fruit to control it, and no effective products for controlling this disease are included in the design of pest control strategies and diseases in the field. The situation as regards Monilinia spp. is completely different, as programmes for applying synthetic fungicide products throughout the crop's entire phenological cycle in order to bring the disease under control are designed.
Fruit production is currently facing a scenario in which it must comply with the applicable legislation and meet the requirements imposed by consumers, and as such it is necessary to innovate and redesign the disease control strategies which are applied so that they do not lead to residue on the end product. This situation led to the establishment of the Operational Group, with the primary objective of controlling Monilinia spp. and Rhizopus spp., the main diseases that affect stone fruit, using strategies for control that leave no residue on the surface of the fruit when they are harvested, in order to be able to access the most demanding markets.
Objectives
The primary objective is to control post-harvest diseases of peaches and nectarines caused by Monilinia spp. and Rhizopus spp., using strategies that leave no residue when the fruit is harvested. The specific objectives are:
1. Determine which products leave no residue on the fruit.
2. Ascertain the maximum period within which synthetic chemicals can be applied in the field without any residue appearing when they are harvested.
3. Determine possible preventive and cultivation measures. Biomarkers to predict the disease's occurrence will also be ascertained.
4. Develop and validate an integrated management strategy.
Objectives
El Objetivo principal es controlar las enfermedades de postcosecha de melocotones y nectarinas causadas por Monilinia spp. y Rhizopus spp. mediante estrategias que no impliquen residuos en la fruta en el momento de la cosecha. Los objetivos específicos son:
- Determinar los productos que no dejen residuos en la fruta.
- Determinar el período máximo a partir del que se pueden aplicar los productos químicos de síntesis para que no se detecten residuos en el momento de la cosecha.
- Determinar las posibles medidas profilácticas y culturales. Adicionalmente, también se determinarán los biomarcadores que permitan predecir las enfermedades.
- Desarrollar y validar una estrategia integrada de manejo.
Activities
-Alternative products to chemicals will be assessed, and the most effective one selected.
-Information will be collected on when to apply the chemicals so that they are not detected during the harvest. Further studies will be conducted if need be.
-The presence of Rhizopus spp. in the field will be ascertained.
-An in vitro and in vivo study of Rhizopus spp. will be carried out at various temperatures.
-Cultivation and prevention practices will be defined and applied in the field.
-The periods for determining the presence of volatile compounds in inoculated fruit will be defined.
-A control strategy that leaves no residue will be defined and validated at a commercial level and then be drafted as a document.
Activities
- Se avaluarán productos alternativos a los químicos y se seleccionarán los más efectivos para su aplicación en campo.
- Se recopilará la información sobre el momento en que se tienen que aplicar los químicos para que no se detecten en cosecha. En el caso necesario, se realizarán más estudios.
- Se determinará la presencia de Rhizopus spp. en campo.
- Se realizará un estudio in vitro e in vivo de Rhizopus spp. a diferentes temperaturas.
- Se definirán y evaluarán las prácticas culturales y de profilaxis.
- Se definirán los períodos para determinar los compuestos volátiles en fruta inoculada.
- Se diseñará y validará una estrategia de control que no deje residuos. A continuación se redactará en un documento.
