PCT No. PCT/CA92/00427 Sec. 371 Date Mar. 30, 1994 Sec. 102(e) Date Mar. 30, 1994 PCT Filed Sep. 29, 1992 PCT Pub. No. WO93/06721 PCT Pub. Date Apr. 4, 1991.The present invention relates to a spraying apparatus and a method of using the same. The spraying apparatus can be used in the spraying of herbicides or insecticides from an aircraft or from the ground. The apparatus provides a separation chamber to remove the small drop component of the spray so that the component leaving the apparatus is essentially free of small drops. Small drops have slight fallspeeds and are subject to wind drift, causing off-target deposits and potential biological impact outside the treatment areas. |
