It is normal that Dieffenbachia plants produce liquid to some extend. 
This is called guttation. But guttation drops usually appear at the tips
of the leaves. Try to reduce watering a little bit. This might help. Be
careful when getting in contact with the sap. It may cause irritation of
the skin. If the liquid is sticky it may as well be caused by parasites. 
Check this up first. 

As Yuccha are inhabitants of dryer areas they are not used in getting
rid of surplus water like the rainforest-inhabiting Dieffenbachia. So this
seems to be a problem with parasites. 
Plants with ridgid leaves can be showered with an emulsion of paraffin 
oil in water to suffocate parasites. 
But get yourself informed before about how to this. Wrong handling 
might damage the plant as well.
