Abstract: A kit is employed in the method for detecting droplet drift or deposition characteristics of spray. The detection kit includes detection membranes carrying immobilized probes, transition probes capable of specifically binding to the immobilized probes, and biotinylated chromogenic probes capable of specifically binding to the transition probes. The transition probes are added to the agricultural spray as tracers. After spraying, the sprayed transition probes specifically bind to the immobilized probes on the detection membranes. The biotinylated chromogenic probes are added to bind to the transition probes through hybridization. After the chromogenic treatment, the deposition volume of droplets is determined according to the color depth, and the droplet parameters are determined according to the position and size of chromogenic spots.

Abstract: A kit for simultaneously detecting the droplet drift or deposition of multiple sprays includes detection membranes fixed with immobilized probes, transition probes capable of specifically binding to the immobilized probes, and biotinylated chromogenic probes capable of specifically binding to the transition probes. The transition probes are added to the spray liquids as tracers. After spraying, the transition probes specifically bind to the immobilized probes on the detection membranes. The biotinylated chromogenic probes bind to the transition probes through hybridization. After the chromogenic treatment, the droplet volume is determined according to the color depth, and the spray deposition parameters of droplets are determined according to the location and size of colored spots.
