See Cucurbita spp Stable protection mechanisms

Any mechanism that protects a host from a parasite can be divided into one of two classes. A stable mechanism is one that does not break down to new strains of the parasite, which are unaffected by that mechanism. This is because the mechanism is beyond the capacity for micro-evolutionary change of the parasite. Stable mechanisms include horizontal resistance, natural pyrethins, nicotine sulphate, rotenones, mineral oil, Bordeaux mixture and other copper fungicides, dithiocarbamates.

The male organ of a flower. When mature, the anthers release pollen for the fertilisation of a female ovule. Staple
