Diazinon and carbaryl: effects on the vegetation of a soybean ecosystem
Two non-persistent insecticides, diazinon and carbaryl, were selected to assess their effect upon the vegetation component of a simplified agroecosystem located on the Piedmont Plateau of New Jersey. Vegetational analysis to determine the effect of the insecticide on the biomass of six species, including a miscellaneous grouping of small cover species, revealed the stimulation of three species (Raphanus raphanistrum, Agropyron repens, and Ambrosia artemisiifolia) and the inhibition of Convolvulus sepium. Vegetational differences between the insecticide treatments are attributed to diazinon's modifying effect of competition to the stimulated species. The changes attributed to diazinon treatment are viewed as neither beneficial or detrimental to the simplified ecosystem, but must be viewed as having potential to alter community structure, food web relationships, and mineral cycling within the experimental area.
