Grapevine is the number one user of pesticides in terms of tons of active ingredients consumed; it alone accounts for 38% of the total volume. IPM methods developed by PURE have the potential to drastically reduce pesticide use in terms of number of applications, frequency index and environmental impact. Our estimated impact is based on data collected in Northern Italy. Our worst case data show that farmers treat 22 times (with TFI=43) per season against powdery and downy mildews, grey mould, dead arm, berry moth, Scaphoideus titanus, mites, and thrips. Our best case data yield 18 applications (TFI=29). To these baseline data, we need to add 2 to 3 herbicide applications on the rows. PURE’s IPM solutions to control berry moth and S. titanus with pheromone and vibrational mating disruption in combination with microbial control agents, adapted agronomic practices and mechanical weed control will reduce the number of applications down to 6 (TFI=8), reducing emissions by a factor of 3. A recent French study also calculates that IPM solutions could reduce TFI from above 20 to below 10. Finding alternatives to copper against downy mildew will stop copper accumulation in the soil and will benefit soil micro and macro-fauna and flora.

Objectives:

The overall objective on grapevine is to provide indications on how to reduce the use chemical pesticides of 10-30 % compared to the current situation by integrating microbial biocontrol agents, low impact substances, agronomic practices and innovative technologies (IPM solutions). Sub-objectives are:

• Produce IPM solutions that address the most critical pest problems in grapevine systems;

• Test candidate IPM solutions on-station and on-farm;

• Assess and compare field-tested candidate IPM solutions using multiple after criteria and endorse viable solutions for mainstream dissemination.

Approach:

This activity will establish a database (DB) of alternatives to pesticides, expert models and vineyard management procedures. As a first step, the DB will include existing commercial and experimental solutions and it will be updated during the project with innovations developed in "New kinoledge and technologies" activities and particulary biocontrol agents against grey mould, powdery and downy mildew and vibrational mating disruption against S. titanus). IPM solutions combining existing techniques (for advanced systems) and including new techniques (for innovative systems) will be designed and assessed ex-ante in terms of cost, benefit, risk, feasibility and adoptability.

Farming system types will be identified based on environmental conditions (climate and relative risk of pest and diseases) and also on such characteristics as farm size, labour organization, farm revenue, etc. These farming types will be located in four geographic areas, which represent the most relevant grape growing conditions in Europe (Atlantic, Continental North of the Alps, Continental-like South of the Alps, Mediterranean). With the contribution of stakeholders (farmers, advisors, policy makers, representatives of industries), the design of IPM solutions will be adapted to the specificities of these farming types, giving particular emphasis to the most relevant problems in each one.

After ex-ante assessment, these candidate solutions will be tested in experimental stations, taking advantage of the facilities brought by the participants in all four geographic areas. Tests in stations will provide the opportunity to analyse some major problems specific to each location more in deep.

Once tested in experimental stations, the IPM solutions will be transferred to a selected group of farms and evaluated under commercial conditions. Positive experience of innovations already implemented in other grape growing areas will be included at this step.

Meetings and/or e-conference among task leaders will be conducted twice a year, before and after vegetative season) to share and update information. Based on these interactions and the fact that new IPM solutions will become available, a new design-assessment-adjustment cycle will be considered.

The IPM solutions will be evaluated ex-post together with stakeholders (farmers, advisors, policy makers, representatives of industries and consumers associations) in order to select the most suitable solutions to be further disseminated to farms.
