A wooden sled with an attached sponge was developed and used to successfully apply glyphosate [N(phosphonomethyl)glycine] to alleyways between small grain plots. The objective for constructing this device was to improve the procedure for killing vegetation in alleyways of small grain experiments. The sponge was attached to the bottom of a hinged platform. The platform allowed the glyphosate- treated sponge to follow the contour of the soil surface as the sled was pulled through the alleys. The sponge was wetted with a solution containing 150 mL L−1 of a glyphosate formulation with 356 g (acid equivalent) L−1 of glyphosate. Excellent vegetation control was accomplished with this device. Advantages over other procedures are (i) glyphosate can be applied when small grain is quite tall (20 cm), (ii) dead vegetation remains on the soil to reduce erosion, (iii) the method prevents spray drift, and (iv) construction costs are minimal.
