>Prophylactic treatment of crops is the antithesis of IPM. 

The line is not as clear-cut in reality as it is in the minds of many.

Beekeepers know this since we often find that by the time we are 
able to get a clear idea of potential pest or disease damage, using 
monitoring, the opportunity for treatment has passed.  In some cases, 
like AFB, waiting for signs of a problem may mean having passed a tipping 
point, especially where distance and scarcity of inspection opportunities, 
accessibility or available labor is a problem, due to distance.  

In the case of mites, a survey for infestation may show a few hot spots, 
but not be able to point out individual hives or yards economically enough 
to counter-indicate a general treatment of all hives and yards.

This varies from operation to operation and area to area.  It seems in 
some cases that prophylactic treatment may be indicated, even to devoted 
IPM practitioners and may even be a part of IPM under some circumstances.  

After all, IPM stands for _Integrated_ Pest management,
