Dodder is a parasitic and twisting plant that, due to the lack of chlorophyll, twists on the host plants as a guest and takes all or some of its nutritional needs from the host crop such as alfalfa. The acceptable amount of sos seeds inside the seeds of agricultural plants is 0.1%. Prevention, agronomic control, chemical control and mechanical control are among the most important things used to reduce the dodder population in alfalfa fields. In order to make a device for removing seeds of sauce in alfalfa with microwaves, the second and third characteristics of microwaves have been inspired.
