IPM Practices by Carrot Growers

Growers were asked to indicate the IPM or alternative control practices they used on their carrot acreage. There were no preset choices, because we did not want growers to be biased towards a particular definition of IPM. Thus, these results indicate which practices growers consider to be alternative.

Table 3 shows the pests which the IPM practices were intended to control.

Growers were asked to indicate if they were experiencing a pest or pest complex that was not responding to any of the available controls, chemical or otherwise. Table 4 summarizes the growers' responses. Please note these are the grower 's own words.

Table 4: Difficult to Control Pests
Concern regarding white mold - can't use Benlate
Deer damage
Rhizoctinia crown rot (with lots of hilling to avoid green shoulder)
Foliar mite infestations - 93-95, hot, dusty conditions
Powdery mildew all year
Rhizoctinia crown/crater rot
Nematodes
Weeds - Mare's tail and Nutsedge
