(a) | Waived if the previous crop is grown and passes certification field standards of equal or higher certified class of seed of the same variety. |
(b) | Reduce to three feet from fields producing the same variety. In addition, each chickpea field for certification must be isolated by three feet from small grain fields. To prevent mechanical field mixing of swathed chickpea seed crop, the planting of small grain between fields, except for three feet of isolation, is recommended. |
(c) | Prohibited, restricted, and other weeds difficult to separate must be controlled. |
(d) | If an EPA-approved product for control of Ascochyta rabiei (ascochyta blight) was applied according to labeled rate during the growth cycle, and followed by additional application(s) if infection is found at field inspection, there is no standard to apply in certified class fields. |
