 Bean-2.0 Weevil Bored (Clean Cut)

Portion for Analysis: 1000 gram work sample & 1000 gram file sample, if applicable


Clean-cut weevil-bored beans shall be beans and pieces of beans from which weevils have emerged, leaving a clean-cut open cavity free from any webbing, refuse, excreta, dead insects, larvae, or eggs. It is necessary to split the bean to determine if the inside is also clean. Use of low power magnification may be used.




NOTE: In addition to functioning as damage, samples containing 2 or more clean-cut weevil bored beans are considered “weevily” and shall be graded U.S. Sample grade. Mung beans may not contain more than 0.1, 0.2 and 0.5 percent clean-cut weevil bored beans in grades U.S. No. 1, 2 and 3, respectively.
