|(a) A field to be eligible for the production of foundation or registered turfgrass sprigs, must have been inspected by a representative of the Texas Department of Agriculture the year preceding the year it is to be planted, and it must have been found free of all other perennial grasses and objectionable weeds. This requirement does not apply to pasture grasses. (b) A field, to be eligible for production of the certified class of stock, must be inspected by a representative of the department during the growing season. At least two inspections approximately six weeks apart must be made. The field must be found free of all other perennial grasses and objectionable weeds. The second inspection must be made within 15 days of planting. During the interval between the two inspections, the soil must not be mechanically disturbed. (c) In lieu of the preceding requirements, a field, to be eligible for production of foundation,
registration, or certified class stock, may be thoroughly treated with a recommended soil fumigant or chemical treatment and left undisturbed for four weeks, at which time an official inspection must be made to determine if the land is free of perennial grasses and objectionable weeds. After fumigation or chemical treatment, soil conditions must be favorable for seed germination and active plant growth in order to determine if the soil fumigation was effective and will qualify the land for acceptance.
