Abstract

A non-mechanical system of applying herbicides to weeds taller than crops by a simple rope wick device is described. The herbicide applicator requires no pumps or moving parts to deliver the herbicide, and it can be built by the farmer at a very low cost. Selective control of johnsongrass (Sorghum halepense (L.) Pers.) in soyabeans (Glycine max (L.) Merr.) with glyphosate was demonstrated in two experiments under field conditions.
