7% of total tomato production costs. Farmers tend to focus their cost-cutting efforts on the higher priced elements of the crop-production system, often labor and packing operations. The prevalent attitude among most farmers, as long as insecticides are available, effective and affordable, is that their use will minimize an element of risk at relatively low cost. However, if all the pest-related costs are aggregated, the total cost is greatly enhanced, and the true cost of ``crop insurance'' can be better appreciated.
When a particular vegetable is in relatively short supply, the price is high and very good pro®ts are made. Under such circumstances, the cost of pest management practices seem insigni®cant and maximization of yield pays handsome dividends. On the other hand, when a vegetable in in good supply relative to demand, the price received by the grower is low, perhaps barely covering costs of production. Under these circumstances, farmers who cut costs where they can, such as unnecessary insecticide use, make greater pro®t.
