Dinitro-analines (LIN) -Introduced in the 1960's
-Binds to tubulin during the formation of
micro-tubules and stops cell division
PPO Inhibitors (FEN)zias -Introduced in the 1960's
-Inhibits PROTOX used for chlorophyll
synthesis which leads to triplet PPIX and
singlet oxygen. Lipids and proteins are
destroyed
-Kills mostly broadleaf
, Glyphosate -Late 1970's
-RoundUp
-Inhibits EPSPS which is where pep
carboxylase would bind to the enxyme,
but Glyphosate is even better suited for
the protein so it binds and stops the
formation of EPSPS
Glyphosate Resistance -Happens with 2 possible mutations to
EPSPS in position 101 or 106
-First report: Ryegrass in Australia
-In America: 1998 (Ryegrass)
ACCase Inhibitors (Dims and -1970's
Fops)
-Inhibits acetyl-CoA to fatty acids
-Only in grasses
