As elementary as it sounds, the key to economical and efficient pesticide use is to apply ratenals only at the rate needed. No farmers violate this intentionally, but defective spray equipment may apply more or less pesticide than needed. For example, applying too little herbicide usually leads to poor weed control and yield reductions. On the other hand, applymg too much herbicide may in crease potential for crop injury, m addition to wasting herbicide dollars. Roller and centrifugal pumps are most commonly used with herbicide sprayers, but both have advantages and drawbacks. Roller pumps produce moderate flow rates at high pressures, are fairly easy to maintain, and they will operate efficiently at tractor PTO speeds. However, the rollers of the pump can wear and must be replaced after continuous use. Abrasive materials like wettable powders and limestone can cause ex tensive wear and should be avoided in roller, gear, in dustrial vane or other rotary-type pumps.

Centrifugal pumps also deliver high volumes of liquid at relatively low pressures Centrifugal pumps require a high speed power source, however, and usually will not operate efficiently at tractor PTO speeds. Some type of speed-up mechanism, such as belts and pulleys or gears, is needed to mcrease PTO speed and pump speed. Constant agitation in the spray tank is essential to insure an evenly mixed herbicide. Without sufficient agitation herbicides can settle to the bottom of the tank causing uneven ap plication; the spray mixture coming from the top of the tank will not contain enough herbicide to control weeds, while the bottom part of the tank will contain a higher concentration of herbicide that may cause crop injury. Thorough, yet moderate, agitation is needed to mix herbicides properly. Ex cessive agitation when tank mixing, however, may cause one of the chemicals to settle m the spray tank. Proper agitation m the spray tank insures even herbicide application con tinuity. A faulty pressure regulator may cause in consistent weed control in |. \iC up to 50% on . . energy costs!

By increasing or decreasing pressure, volume of herbicide applied will be increased or decreased. A pressure regulator is essential for maintaining consistent delivery of the spray mixture. Growers can choose from three types of nozzle tips, all of which deliver various spray patterns: flat spray, cone spray and flood spray nozzles. There are two basic types of flat spray nozzles: flat fan and even spray. The first is designed for broadcast applications and may have an “F” designation. The spray of the adjacent flat fan nozzles must overlap for even distribution. An “E’’ designation ap plies to even spray nozzles designed for ban' spraying. It delivers an e i il amount of herbicide acr the spray pattern. Both types of :Ijs work best at a press above 20 psi. Pressure a! eve 40 psi should be avoidt 1 to reduce spray drift. Cone spray nozzles are usually designed to operate at higher pressures than flat spray nozzles to produce fine spray droplets. There are two general classes of cone nozzles: hollow cone and solid cone, both of which have large orifices to reduce cloggmg.

Cit: I Phone operates at extremely high pressures and is best suited for insecticide applications. Operating efficiently at a pressure range of 30 to 50 psi, the hollow cone nozzle delivers a small volume of spray well suited to post emergence applications. The swirl chamber - a popular type of hollow cone nozzle - can operate at pressures below that of flat spray nozzles and still deliver an even coverage of pesticide. For broadcast ap plications of preplant in corporated and preemergence herbicides, a small volume of liquid is sufficient to give adequate coverage of the soil and good weed control results. Therefore, flat fan and swirl chamber nozzles are usually preferred. Flood type nozzles are useful for high volume coverage at low pressures; capacity is measured at 10 psi. These nozzles deliver a spray of large droplets in relation to flat spray and cone nozzles. This is an advantage where spray drift could be a problem. The flood type nozzle’s spray pattern must overlap the adjacent nozzle’s pattern by 50 percent for even herbicide distribution. Zip G 4-19
