Abstract
A spraying system for the application of fertilizer, insecticides, fungicides, etc. to plants, vegetables, small trees and lawns. The spraying system presents several improvements over the original Lacy Sprayer (see U.S. Pat. No. 5,398,852) inclusive an improved bladder attachment and improved bladder design, and a new pressure-limiting flow restrictor to ensure safe operation, and a spray discharge fitting incorporating a porous filter to protect the bladder from excessive stresses. The spray hose is connected to this assembly. The improved system facilitates a method of use in which the tank containing the spray solution is placed stationery in an area to be sprayed. The operator attaches a long (30′+ or −) small diameter spray hose for remote spraying within a radius permitted by the spray hose. The spraying system avoids the need to pump or to carry a heavy tank while spraying. Moreover, the continuous, higher pressure of the spraying system provides a wide range of operation from a foggy mist to spraying the tops of good size trees, and saves more than half the spray solution normally wasted.
