Site-specific application of plant protection products in Precision Farming by direct injection

In agriculture, tank mixtures with several plant protection products (PPP) are frequently used, which makes it impossible to apply specific plant protection products to specific areas. Therefore a prototype of a field sprayer with a direct injection system was developed as part of a joint project between the company Herbert Dammann GmbH and the Julius Kühn- Institute. This framework enables a real-time site-specific dosing of plant protection products and water from separate containers with direct mixing before the application without residual amounts. Results show a high accuracy in the working range of the selected dosing pumps by means of test bench measurements and field tests Field tests for site-specific weed control in winter wheat demonstrate the applicability of the system under practical conditions and enable a precise application of various herbicides.
