Benefits of technology

This patented inventor describes an improved type of chemical that works effectively against plants like grasses or crops without harming them. It also contains ingredients for killing unwanted vegetation such as leonurus quinquefasciatus (L.) Schumannii).

Problems solved by technology

This patents discusses how different types of herbs like cyathodextrine sulfurfonate (Couplers) and arthrosporium nitrosum (Astoria), commonly known as Weisskopfweckles, affect crops' growth and development through their effects on root systems that contribute significantly towards crop loss. Existing treatment techniques involve applying synthetic herbics alone without considering potential environmental concerns associated therewith.
