Herbicides Analysis

More and more, the question of herbicide residue and its potential for crop damage requires an accurate assessment of residue presence. A&L Canada, recognizing this as an important concern, offers plant bioassays to screen for the presence of crop damaging chemicals. Bioassays are recognized as a useful means for determining the presence or absence of herbicide chemicals that may inhibit normal development of sensitive plants. Bioassays use herbicide susceptible plants, which are exposed to the suspect soil and grown alongside a control sample for comparison. The degree of plant growth and its physiological characteristics are compared to the control plant to assess whether or not the soil-seed combination will produce a healthy plant stand. Bioassays can identify known residues as well as potential residues in soils with an unknown history of herbicide use.

Pesticides Analysis

A&L Canada has complete pesticide analysis capabilities for water and soil. More than 100 pesticides are analyzed for prevention and diagnosis of crop damage. Cropping rotations or renting land may require specific pesticide analysis to ensure the residue levels are not such that they restrict the growth of succeeding crops.
