Extract

A number of portable spray systems have been designed for application of herbicides to experimental small plots. Several have been designed for special purposes or conditions which confronted the experimenter. Buchholtz, Robinson and Dunham, and Davis described portable small plot sprayers for use where the experimental areas were small or no gain in precision was found by using more than rod-row plots. In general these and other spray systems have some deficiencies, which are accentuated when the equipment is to be used in small plot experiments requiring a high degree of precision. The equipment described here (Fig. 1) was designed to spray plots 3′ × 18′ and smaller. If the plot size is greatly increased the utility of this unit in its present design is materially reduced. Other factors desirable for larger size plots have necessarily been sacrificed in order to enhance qualities deemed more essential for the precision small plot work.
