Acetanilide
Toxicology and Mode of Action
The acetanilides (propachlor, butachlor, alachlor and metolachlor) are used
as preemergence herbicides against annual broad-leaved weeds and grasses. The
acetanilides owe their herbicidal activity to the inhibition of photosynthetic
electron transport and energy production. See
Table 5.10
.
Several formulations of Alachlor, namely Crop Star, Lasso, Micro-Tech
C, and Partner are RUP products due to their oncogenicity.
Dual is a product with the active ingredient metolachlor. It has a signal
word
caution
and is therefore a slightly toxic to relatively nontoxic product.
Figur e 5.8
Roundup is a contact herbi cide containing glyph osate. This
