Vertical and horizontal distribution of pesticide microcapsules applied on the porous surface
The aim of this study was to compare the aggregative behaviour of pesticide microcapsules (Detmolmic, a.i. fenitrothion) applied by a pipette on porous and non-porous surfaces (paper vs. glass). We compared the dispersion pattern of microcapsules in wet (WD-G) and dry droplets (DD-G), both applied o...

| description | The aim of this study was to compare the aggregative behaviour of pesticide microcapsules (Detmolmic, a.i. fenitrothion) applied by a pipette on porous and non-porous surfaces (paper vs. glass). We compared the dispersion pattern of microcapsules in wet (WD-G) and dry droplets (DD-G), both applied on a glass surface, and in dry droplet (DD-R) applied on a paper. In both types of dry droplets, the microcapsules tended to aggregate. However, the aggregation was much higher on the glass surface than on the rough paper surface. The fraction of the smallest microcapsules tended to submerge into the internal structure of the porous material. The surface bioavailability of microcapsules was lower on the paper (25 %) than on the glass (100 %). We can conclude that while testing and modelling the activity of encapsulated pesticides, the effects of vertical and horizontal arrangement of microcapsules inside of droplet deposits should be taken into account. |
