Good morning everyone, today Im talking to you about a new way farmers can take on disease-related issue on grapevine while taking care of the environment and invest in a technology that can help to save capital, namely Decision Support Systems.

1

European Community Directive 128/2009

Member States shall take all necessary measures to promote low pesticide-input pest management []so that professional users of pesticides switch to practices and products with the lowest risk to human health and the environmentArticle 142

This is a quote from article 14 of the European Community Directive 128 of 2009. It basically says that each member state should push farmers to switch to more environmentally friendly practices when it comes to apply pesticides. And, as we all know, a Directive is binding only as regards the objectives to be achieved.

2

EU Reg. 1305/2013 of Support for Rural Development3CAP Reform 2014-2020to promote knowledge transfer and innovation in agriculture [];to promote innovative agricultural technologies and support sustainable forest management;

This is another quote from a European Regulation, intended to support Rural Development, where some priorities are presented. It is clear to understand how Europe is insisting in promoting new technologies able to help farmers to be more sustainable and innovative driven.

Second Pillar of the CAP 2014-2020:4GREEN DIRECT PAYMENTS

Now, probably you are wondering why such a technology should be adopted by farmers. Well, the second pillar of the Common Agriculture Policy, with the projection 2014-2020, contemplates measures that rewards farmers for introducing practices beneficial for the environment and the climate. Specifically, 30% of the budget of Rural Development is given to those farmers who apply innovative technologies, such as DSS.

Here it is showed how a standard bulletin from a region, in this case Emilia Romagna, looks like. So, we have the number of the bulletin, the reference date, and the crop indication, grapevine in the example, of course.Then we have the indication about the phenological phase in which the grapevine is, and the diseases appearing during that phase. As we can see, indication is lacking of specific information. We have no indication about the dose and application of the Plant Protection Product, and just hypothesis about its spread.

The study was based upon reports and data coming from the Decision Support System called Vite.net. This software collect real time data about soil and air as well as detecting the phenological phase of the grapevine.A mathematical model later analyzes all the data and elaborates feedbacks estimating the incurrence of the disease. Moreover, relying on information added by the farmers, it suggests the best chemical product to apply to the crop to prevent or cure the disease. More important, it specifically indicates the least amount of plant protection product sufficient to protect the crop.

10THE STUDY

Data analysis process11

The study I have undertaken was based on 23 different farms implementing the DSS, spread in 6 different Italian regions. Thus, I compared the cost resulting from the implementation of the DSS with the one that would have bene resulted if the regional bulletins were applied. The cost are exemplified in the next tables.11

Benefits for farmers18

Vite.net consents to keep protected the crop as if the advices from the bulletins were adopted;

Vite.net is a realistic and viable technology helping farmers to be efficient, autonomous, and technically advanced;

Vite.net helps farmers facing grapevine diseases and to considerably save capital and comply proficiently to the European Directive 128/2009.Conclusion19/19
