Abstract

Peach trees treated with the herbicide mixture of 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) and 3-amino-1,2,4-triazole plus ammonium thiocyanate (amitrole-T) had higher leaf nitrogen and more growth than trees where the weeds were controlled by hand hoeing or a black plastic mulch. Apple trees had higher leaf nitrogen and more growth when treated with simazine and amitrole-T than with no weed control. In both peaches and apples more growth and higher leaf nitrogen resulted from the herbicide treatments than from supplemental nitrogen treatments, indicating that the herbicide influenced the nitrogen metabolism of these trees.
