Destruction of weeds grown in pots using the hot foam method

Generally, weed control is conducted in the form of hoeing or chemical control. Hoeingis difficult and performed using manpower; on the other hand, chemical control has harmful effects on the environment. In this study, the hot foam application was employed as a method for weed control. For this method, first a hot foam machine with a digital indicator was produced. Wild oats (Avena fatua), English ryegrass (Lolium perenne), and wild clover (Medicago sativa) were separately planted in three control pots and in three hot foam application pots. For each plant, comparisons were made in terms of the average number of weeds (blades), weight per 15 weeds (gram), and length (mm). As a result of hot foam applications performed on English ryegrass, the number of plants decreased by 78%, the length decreased by 45%, and its weight decreased by 68%. In the wild oats, an 89% decrease was achieved in the number of weeds as a result of the hot foam application. In the wild clover, a 92% decrease was achieved in the number of weeds. As a result, the hot foam application proved to be successful in destroying weeds for all three plants.
