Extension Rods 



No spraying outfit is complete without an extension rod. It is an 

 indispensable adjunct in reaching to all parts of the trees, expediting 

 the work and improving the quality of the spraying. Besides these 

 advantages, it is a protection to the operator, enabling him to evade 

 a wetting from the spray mist as it is blown or drifted about. Rods 

 are usually made of 1-4-inch piping and are cut to any desired length 

 based upon the requirements. Bamboo rods are also used for the same 

 purpose. Piping may be cut in short lengths and lengthened or short- 

 ened at will to suit the occasion by means of couplings. 



Stop Cocks 



Stop cocks are very serviceable and almost imperatively necessary 

 in large spraying operations. By cutting off the flow they prevent 

 waste in moving from tree to tree and are invaluable to successful 

 and economical spraying. There are only a few types, the best of which 

 is the brass stop cock with stuffing box that may be tightened so as to 

 prevent all leakage. This type has a cut-off handle two inches long 

 extending on just one side of the stuffing box and readily cut on or off 

 by the thumb. 



Nozzles 



There are nozzles of all kinds and sizes and one must be governed 

 by the requirements in each case. In spraying for scale insects it is 

 of prime importance to use only nozzles throwing a finely divided 

 spray. Maximum good results are obtained from nozzles insuring 

 this important feature. 



The best types of nozzles used in Georgia are the Vermorel, Bean, 

 Friend, and Mistry, Jr. These may be attached to the rod singly, in 

 couples, or sets of three or more. In the writer's opinion the best 

 nozzle now on the market is what is called the Mistry, Jr. The Bean 

 Manufacturing Company also make similar nozzles. In this type 

 the construction is exceedingly simple; they do not easily become 

 clogged and are readily cleaned when the flow becomes obstructed. 

 They are without the degorger common to the Vermorel type and the 

 objectionable features occasioned by the catching of these prongs on 

 the limbs, pulling off the fruit, etc., are eliminated. Their extreme 

 simplicity, the ease with which they are cleaned and the rapid and 

 thorough work they insure puts them well at the head of the list in 

 the world of nozzles.
