With the help of targeted treatment of individual plants with the ARA crop protection sprayer, herbicides can be used where they are needed. According to the provider, the use of pesticides will be reduced by up to 90%. The selectively applying crop protection device ARA is intended to apply the crop protection products precisely to the crop or weed as required. This is done with the help of 156 nozzles, which are installed at a space of 4 cm over a working width of 6 m. The nozzles are controlled separately for individual plant treatment. The spray corridor of a nozzle is 6 x 6 cm. The surface is scanned during the crossing using six cameras. Depending on the previous work setting, the right nozzle is used at the right time. Depending on the work order, the plants are treated directly with insecticides and fungicides. When herbicides are used, weeds are treated directly. Weed control can be done using two methods: 1. In addition to the weeds, the cultivated plant can also be affected in places. 2. No crops may be infected, only weeds. A comparative application was carried out in the cultures of onion, lettuce and cabbage. The crops were treated with herbicides several times during emergence between mid-April and the end of May (four to five treatments). The experiment consisted of the following test variants: - Standard: widespread application of the crop protection product (common tank mixture) - Application of the standard tank mixture with the ARA sprayer; only the weeds are treated - In addition, Beloukha (pelargonic acid), a natural active ingredient that is less tolerated in onions, is tested in the same way. If successful, the ARA crop protection sprayer could enable the use of herbicides in sensitive crops of medium natural origin. The tests were carried out in two practical companies in Lower Bavaria.
