ABSTRACT
This chapter focuses on the known nature of nematicidal agents and their application requirements with respect to their continued and modified use, compared to and integrated with other nematode control strategies. It emphasizes the beneficial and deleterious effects of nematicides on crops and on other biological components of the agroecosystems to which they are applied. Modifications to the timing of application relative to planting could be made and that more research is needed on efficacy and phytotoxicity associated with low dosage treatments. Direct plant growth stimulation by nematicides has been suggested or implied in interpretations of numerous experiments on control of nematodes, insects, plant pathogens, and weeds, in which the target organism was not abundant enough to produce improved plant growth or yield when controlled. Decisions on nematode control are always economically motivated, whether short-term, single-growing season, or long-term, multiple season in nature.
