In view of environmental protection, labor shortage, and competitive pressure, plant protection in viticulture is facing increasing challenges. Digital technologies can make a significant contribution to addressing these challenges. First digital products for plant protection in viticulture are available on the market, but are not yet widely used due to their high costs and limited practicality. This is where the DigiSpray project comes in. The objective is to develop and test innovative digital technologies for ecologically and economically optimized plant protection in viticulture. On the one hand, assistance systems for plant protection are created to support tasks such as the adjustment of plant protection equipment, the verification of spray deposition, the documentation of pesticide use, and other related activities. On the other hand, automation systems for plant protection equipment are developed to, among other things, improve leaf coverage and reduce spray drift. The focus is on low-threshold solutions that winegrowers can easily integrate into their usual workflows and existing equipment. The various technologies are integrated into a digital ecosystem, tested in demonstrators, and made available as open source together with guidelines. Experts from the field of viticulture are specifically involved in the project through workshops.
