PHYTOTOXICITY:

As with most chemicals, misuse of nematicides can result in development of phytotoxicity.

Vydate (oxamyl) produced these symptoms on the leaves of roses.

DBCP (no longer available for use in the US) produced these symptoms of phytotoxicity on Philodendron and on cotton.

In this somewhat unusual case, phytotoxicity was observed on wheat grown the year following the use of both Enzone (sodium tetrathiocarbonate) and Metam-sodium prior to planting potatoes. Wheat in the treated areas came up either sooner or later than wheat planted in nontreated areas and then died during a spring feeze. The differential timing of wheat emergence was not noted until after the freeze occurred.
