Provided are methods of using molecules as described herein in supporting crop viability and yield, such as by protecting crops from pests. In some cases, the methods inhibit apyrase enzymes by contacting such enzymes with a compound of the formula

##STR00001##

wherein G, Z, and R.sup.1 are as described herein.

In further embodiments, an apyrase inhibitor as described herein is used in combination with one or more pesticide to treat a crop at risk of disease.
