In acid medium (pH <6) these are mainly molecular ([H.sub.3][BO.sub.3]) and associated ([H.sub.3][BO.sub.3]OH-) forms of orthoboric acid. In alkaline waters (pH > 7) there are slightly dissociated forms of tetra-, penta-, hexa- and other polyboric acids of the general formula nB2O3 x m[H.sub.2]O or H3m2nBm03m- n.
Capinera & Guedes Rodrigues (2015) reported that the leatherleaf slug Leidyula floridana (Leidy, 1851) (Gastropoda: Veronicellidae), although susceptible to the toxicant orthoboric acid when it was applied to foliage, was not affected when orthoboric acid was provided as a bait formulation (sold commercially as Niban[R]), seemingly because the slugs did not ingest the bait.
The peaks correspond to rhombohedral [B.sub.4]C for R4B-1 and R4B-2 and are consistent with JCPDS card number 35-798, although smaller peaks corresponding to unreacted orthoboric acid, [H.sub.3]B[O.sub.3], and a band of disordered carbon were detected.
