PCT No. PCT/DK97/00325 Sec. 371 Date Jan. 29, 1999 Sec. 102(e) Date Jan. 29, 1999 PCT Filed Aug. 1, 1997 PCT Pub. No. WO98/06257 PCT Pub. Date Feb. 19, 1998A method serving the purpose of spraying a crop with a plant protective liquid. The liquid is sent out in the shape of a number of clouds (10) of atomized liquid in the direction of the crop (11) via a number of liquid nozzles (9) placed on a sprayer boom (8) which, at the same time, is driven across the crop (11). The nozzles (9) are adjusted to put each atomized liquid cloud (10) into whirling movement. The whirls (10) created thereby are stiff and stable against drifting. The liquid whirls (10) can be supported by a curtain of air whirls (14). By means of the method and the sprayer boom according to the invention, a crop can be sprayed efficiently with a minimum use of crop spray. |
