I really can't tell from your pictures but it reminds me of caterpillar feces though more than I have ever seen. LOL . I would try using B.T. It is not a poison to people or other insects. If it isn't caterpillar damage, it won't hurt anything and you can then try a general systemic on it.

"What kills caterpillars?
B.t. to the Rescue Bacillus thuringiensis var. kurstaki is a naturally occurring bacterium that kills certain leaf-eating worms and caterpillars. Simply spray Caterpillar Killer onto trees, shrubs and vegetables so that worms and caterpillars eat the treated vegetation."

Amaranth leaves are very much edible and a good nutrition source in their own right.

I think plant bugs had caused serious damage to your amaranth leaves. You should apply a layer of mulch will help to prevent weeds and conserve soil moisture. Or you can also consult some professional exterminators like City Pest Control, http://www.eliminexpestcontrol.com , long island exterminators or any other local pest controller, who will do an inspection and early detection and they will make identification of the signs of pest presence at your amaranth leaves.

Vincent rose, it would be cheaper to toss the plant and buy 100 more rather than pay for pest control for a caterpillar.
