Considerations for blending seed.
(1) Size of seed blend permitted is dependent on factors such as quality of seed lots to be blended and the conditioning plant facilities.
(2) A blend data sheet is filed with the certifying agency and must be maintained by the seed conditioner. Laboratory analysis must be completed before tags are issued.
(3) Seed must be blended by a seed conditioner approved by the department under WAC 16-302-125.
(4) A representative of the certifying agency may supervise the blending operation.
(5) A tetrazolium test may be used in lieu of a germination test.
(6) Field run lots of seed may be commingled to facilitate conditioning. The blend fee shall not apply.
(7) Remill lots of seed may be blended prior to testing to facilitate processing.
(8) Individual lots of grass seed shall not contain more than one hundred eighty per pound and alfalfa and clover shall not contain more than ninety per pound of objectionable weed seeds.
(9) Individual lots must be free of prohibited noxious weed seeds.
(10) Two or more sod quality lots may be blended and tagged as a "sod quality mixture or blend." Appropriate tags will be issued and blend fee shall be applicable.
(11) Seed lots resulting from a blend of different certified classes may only be labeled at the lower class.
