Testing for pesticides/herbicides in soil, solid matrices & biota

ALS offers a variety of methods and applications for pesticide, herbicide and fungicide analysis. These contaminants are a concern for both human health and for their negative effects on soil microbial communities, which can lead to soil quality degradation. The harm to these microbes can effect local ecology as well as the productivity of agricultural fields. ALS provides comprehensive pesticide/herbicide testing in soils and plant tissues to assess the level of contamination.

Accredited pesticides/ herbicides testing in soil/solids & biota

ALS has experienced chemists who specialise in pesticide residue analysis. We provide timely, quality results to many people in the agriculture sector including farmers, crop input dealers, research organizations and numerous other companies. The information we supply is used to enhance crop production, maximize economic returns and minimize the environmental impact on soil and water.

Pesticide residue analysis:


  • Organophosphorus pesticides 
  • Organochlorine pesticides 
  • Pyrethroid 
  • Triazole fungicides 
  • Organonitrogen pesticides 
  • Dithiocarbamates (e.g., maneb and mancozeb) 
  • Acid herbicides (e.g., 2,4-D, dicamba) 
  • Carbamates 


  • Nitro- and chlorinated phenols (e.g., trichlorophenol, pentachlorophenol, dinoseb) 
  • Benzoic acid herbicides   
  • phenoxyacetic acid and related herbicides and their esters (e.g., 2,4-D, 2,4-DB, 2,4,5-T, dichlorprop, MCPA, mecoprop, Silvex, etc.)   
  • triazenes (atrazine, propazine, simazine),    
  • Bromacil,   
  • N-arylcarbamates   
  • Glyphosate (Roundup™)   
  • Quaternary amines (paraquat and diquat)   
  • Sulfonylureas,   
  • Substituted urea's.    

Trace level organochlorine pesticides in sediments & soils

Restricted organochlorine pesticides are still harming our environment

Organochlorine pesticides (OCPs) are synthetic chemicals that have had worldwide historical use for pest control, primarily as agricultural insecticides. Although restrictions against their use have been in place for decades in most industrialized nations, OCPs are highly persistent, and remain prevalent in sediments. These compounds are hydrophobic, strongly associated with carbon and fine sediment, and bio-accumulate. Their deleterious effects occur primarily through ecotoxicological impacts, even at trace levels. ALS is able to confidently test for OCPs with accuracy and precision, to low detection limits.
