Quarantine inspections are conducted to monitor quarantined pests that could be introducted into Texas from out-of-state agricultural shipments or transported from quarantined to pest-free areas of Texas. Nursery plants, fruits, vegetables, hay, sod or any other article that can harbor a quarantined pest are inspected to ensure that they are free of quarantine pests and meet import requirements of Texas. Road station inspections are conducted to ensure that the articles entering into pest-free areas from quarantined areas are free of pests. Plants imported from foreign countries for propagation are monitored through Federal Postentry quarantine inspections. Federal permits are issued for soil, plant pests, noxious weeds or biological control organisms brought into the state for experimental use.
