Roundup Resistant Weeds

Well what were we thinking? That glyphosate (sold as Roundup) would keep on killing weeds forever? Nope – we now have glyphosate-resistant weeds in 20 states (they don’t mention Canada in this but…)

The weed folks say we have to stop using glyphosate regularly and mix up the herbicides being used so weeds can’t develop genetic resistance. Too bad – too late – horse out of barn alert here.

Organics Too

Resistance to any control – chemical or organic – can be expected from any insect or weed if the control products are used to often without a rotation. Note I included “organic” in this as well so organic gardeners that rely on a favourite control exclusively are reminded to switch up in an approved rotation.

I once created a herd of soap resistant aphids in my nursery propagation house because I wasn’t paying enough attention to my rotations. Took another year to eliminate that particular production problem by using a full rotation. Learn your own lesson from mine.
