Effects of selected herbicides on perennial grasses and water pollution under tropical high rainfall conditions
The following herbicides were evaluated for their effect on perennial grasses and water pollution in El Salvador, Central America: MSMA (monosodium methanearsonate), DSMA (disodium methanearsonate), cacodylic acid (hydroxdimethylarsine oxide), paraquat (1,1" dimethyl-4,4"- bipyridinium), dalapon (2,2-dichloropropionic acid), amitrole (3-amino-s- triazole), atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine), diuron (3(3,4-dichlorophenyl)-1,1-dimethylurea), and karbutilate (m-(3,3-dimethyluereido) phenyl-t-butylcarbamate).

Abstract
The herbicides were sprayed on drainage channels at different dosage levels. Some plots received one application, others received two, and still others received three applications. All herbicides except atrazine effectively controlled perennial grasses. Cacodylic acid was the most effective contact chemical, with dosage levels of 7 and 10kg/ha achieving 77 percent control of the grasses after two applications.
