High Performance Liquid Chromatography (HPLC) Method for Analysis of Metalaxyl (UV) , Propoxur , Paclobutrazol , Abamectin , Propanil , Iprodione , Chlorpyrifos-methyl (Dursban) , Pentachlorophenol , Fenvalerate .

Metalaxyl , also known as methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate, is a systemic fungicide with the chemical formula C15H21NO4 . It is used to control Pythium and Phytophthora in vegetables. It has suffered a resistance problem going back to the 1980s.

Propoxur is a non-systemic insecticide produced from catechol with the chemical formula C11H15NO3 . It has a variety of uses from turf, forestry, and agricultural pests to household pests and fleas.

Paclobutrazol ( PBZ ) is a synthetic triazole compound with the chemical formula C15H20ClN3O . It is used to control plant growth as an antagonist of the plant hormone gibberellin. Through reducing reducing internodal growth, it causes stronger stems, greater root growth, and earlier fruitset. It can also reduce frost sensitivity in plants.

Abamectin is a insecticide with the chemical formulas C48H72O14and C47H70O14 . It is also used to control fire ant populations. In veterinary cases, it is used to deworm horses as well as an antihelmintic.

Propanil is a contact herbicide with the chemical formula C9H9Cl2NO . It is one of the most widely used herbicides in America. It works as an inhibitor of photosynthesis and CO2 fixation in weeds.
