Abstract:

The surface tension of a series of dilution rate of chlorothalonil and mancozeb were measured. The feature of target plant leaves were observed. The pesticide wetting ability (PWAL)on leaves and the pesticide retentivity(PRL) of leaves were determined. The relationship between leaves feature and the behavior of pesticide were analysed.The results show that PRL and PWA are relevant on some degree. PRL is also affected by liquid adhesion on leaves . PWAL and PRL are affected by characteristics of the leaf surface.

Key words: bioengineering, non-smooth surface, surface tension, contact angle, pesticide retentivity
