It depends upon the vegetable, and the pest. For example, the wait's just a day after Sevin's used against beetles and grasshoppers, on aspragus. It's 3 days after Sevin's used against Mexican bean beetles, on lima and snap beans. But it's 14 days after Sevin's used against flea beetles and harlequin bugs on collards, kale, spinach, and turnips. So it's important to check the label.
