The challenges of integrated production in strawberries 

Following the prohibition of certain plant protection products under Directive 91/414/EEC and in the light of market demands, producers of this crop now regard biological control as an essential tool for the future, with added value. In Huelva, where 94% of Spanish strawberries are grown, between 60% and 70% of production is now integrated and biological control is used on around 400 hectares, where sporadic release of beneficial organisms is an increasingly widespread practice. Caterpillars are a major pest of this crop due to incidence in the post-planting period, which is the most sensitive, and plant protection products can play a crucial role in the establishment of beneficial organisms. The incidence of each species varies according to region, season and year. The red spider is the most problematic pest, requiring on average 2-3 treatments per plot, and on some farms 6 or more. Although Phytoseiulus persimilis at 20 indiv/m2 affords a good solution, this mite can be difficult to establish. With new varieties and the use of more environmentally friendly pesticides, the incidence of aphids has increased. Identifying species is vital in biological control, which provides good control of the most common species. Thrips incidence is generally low, and 25-35% of plots can be treated with a single application. Therefore, the use of Orius laevigatus for biological control is questionable. In Huelva, where most of the production is in March, April and May, there has been no incidence of Drosophila suzukii to date, although high populations have been recorded in other crops.
