La. Admin. Code tit. 7 § XIII-515

Current through Register Vol. 50, No. 11, November 20, 2024

Section XIII-515 - Seed Sampling (Formerly Section 137)

A. Seed sampling will be performed at the request of the grower.

B. Except as provided by §515. D 2, official samples to determine eligibility for certification shall be drawn only after the seed is conditioned.

C. Sampling of Bagged Seed

1. Each lot of seed must be stacked so as to facilitate sampling.

2. A LDAF inspector will sample at random, by probing, a specific number of bags from each lot. The number of bags to be sampled from each lot is as follows: five bags, plus 10 percent of the total number, not to exceed 30 bags per lot. In lots containing six bags or less, every bag will be sampled.

D. Sampling of Bulk Seed

1. Cleaned Seed in Bulk

a. A LDAF inspector will collect a minimum of four samples, at intervals of 4 feet, by probing the entire depth of the bin or storage area.

b. All samples will be blended into one representative sample for each bin or storage area.

2. Uncleaned Seed in Bulk

a. A LDAF inspector will collect a minimum of four samples, at intervals of 4 feet, by probing the entire depth of the bin or storage area. All samples will be blended into one representative sample for each bin or storage area.

b. A second representative sample will be drawn within 60 days after the first sample, after conditioning, for determining purity.

E. Analysis of samples shall be performed according to the current rules of the Association of Official Seed Analysts.

F. Resampling Policy

1. Except in special instances, as described below, only one sample shall be obtained from each certified lot.

a. When a certified seed lot fails certification requirements due to physical or mechanical purity factors, such as excess inert matter or weed seed, the seed may be reconditioned if the contaminants are separable. A complete purity analysis and germination test will be required on the reconditioned lot of seed. Certified seed rice which fails certification due to the presence of red rice seed in the sample shall be subject to the terms of Subparagraph e below.

b. Should a seed lot fail certified seed germination standards on the first laboratory test, a re-sample for germination test only for that seed lot will be permitted. Only one re-sample per seed lot will be permitted.

c. Whenever a certified seed lot is divided into sub-lots, both a purity and a germination test will be required for all sub-lots.

d. The last and most recent laboratory test report for a seed lot shall be the final analysis used to establish the eligibility for certification and will determine the information to be placed on the tag.

e. When a certified seed rice lot fails certification requirements due to the presence of one red rice seed in the original four pound sample, then a second 8 pound sample may be drawn from the lot. If one or more red rice seeds are found in the second sample, the lot will be disqualified on the basis of red rice content. If no red rice seed is found in the second sample, the lot would meet certification requirements. Certified seed rice whose original sample contains the presence of more than one red rice seed may not be re-sampled.
