It is the combination of autonomous tractor and automatic spray that make it a win-win situation. First of all the unmanned tractor means a 30% lower labour cost. Secondly a precision spray means 25% less spraying liquid is needed. This results not only in less costs, but also in a healthier plant and environment.
The prototype of the tractor and spray were developed in a public-private collaboration between KWH Holland, Probotig, Abemec and Wageningen UR. The project was financed by Productschap Tuinbouw and the EU through the project PURE.
Fertilisation and pear leaf flea
The results of various other running tests were also handled at this Open Day. It turns out that there is a link between nitrogen fertiliser and pear leaf fleas. Growers can limit the damage caused by these fleas through fertilisation. It was also shown that a higher level of phosphate in trees is important for the storage quality and colour of pears. Other items on the agenda were developments in the area of new varieties, new diluents, mechanical trimming and various Elstar mutations.
