Background:

Photo ACTA                          

The contribution of apple and pear production to the total volume of pesticide consumption is disproportionate relative to the area they cover. On average, these crops receive a surprisingly high number of pesticide treatments: 20 to 30 for apple and pear. Moreover, pesticide emissions into the environment tend to be relatively high because of the horizontal orientation of spraying with air support. Consumer awareness of pesticide residues is high when it comes to these food products. The implementation of PURE IPM solutions will yield significant reductions in pesticide use in these crops. We estimate that our component methods - against apple scab, codling moth, brown spot and pear psylla - integrated into IPM solutions will reduce the number of treatments by 10 for both apple and pear. Using the SYNOPS model, these reductions in frequency correspond to a 25% reduction in risk. In addition, innovative spray technique combined with PURE envisioned IPM solutions will reduce drift by 75% and pesticides volumes by 40%. 

Objectives:

Design new innovative IPM solutions in pomefruit which will substantially and realistically contribute to a reduced risk to human health and environment. These new designed innovative IPM solutions are tested on efficacy, economic, health risk and environmental aspects under well controlled conditions and as total IPM systems in commercial orchards in close co-operation with stakeholders.

• Identification of key pests and diseases for the implementation of IPM in pomefruit, selection of innovative tools which can substantially contribute to reduce health risk for workers and environment, and reduce the dependence on pesticides. Design new IPM solutions using innovative tools including decision making indicators, prophylaxis and alternative control methods for different European regions.

• Ex-ante assessment in line with "IPM assessment and methodology" activity of innovative candidate IPM tools and IPM solutions on economic (labour, yield, product quality, product price) environmental and health risk for workers aspects.

• Development of novel innovative IPM tools and solutions assembled from IPM tools, in relation with "IPM assessment and methodology" for pomefruit, under well controlled, experimental conditions in different European regions.

• Test under commercial field conditions the most promising innovative IPM tools and solutions for pomefruit which have realistic opportunities to reduce health risk and risk for environment, and reduce the dependence on pesticides.

• Ex-post assessment of the most promising IPM tools and solutions on economic (labour, yield, product quality, product price) environmental and health risk for workers aspects.

• Description of benefits on newly developed IPM tools and solutions ready for dissemination into practice.

Approach:

This activity will implement a system and multipest approach, initially focusing on the key pests and diseases of pomefruit, and aiming to integrate the most promising innovative IPM tools into advanced fruit production strategies. Among these tools, available decision support systems and prophylactic methods will be improved and implemented for the keystone pests and diseases. Biological control through habitat conservation will be extended to lepidopteran pests and aphid communities. The evolution of hail nets towards pest exclusion netting will be evaluated on the whole system. New tools issued from "New knoledge and technologies" activities will be used.

A repetitive cycle will be used over the years, where an IPM strategy is designed, tested using multifactorial experimentation under controlled condition and on-farm experiments, assessed, improved and redesigned. By that, newest insights are incorporated. Key pests and diseases can be different for different European regions and consequently, developed innovative IPM solutions will be different for different regions. Harmonised methods will be used to ex-ante evaluate novel IPM tools and solutions and to ex-post assess improved promising IPM tools and solutions. Ex-post assessments will be done with emphasis on expected benefits in terms of health risks for workers, environmental aspects and reduced dependency on pesticide use on the one hand side and on possible economic and institutional hindrances to implement promising IPM tools and solutions in practice on the other hand side.
