Abstract:
Methyl bromide (MB) at rates of 500, 1000 and 1500 kg/ha, Terraclor 75 WP (PCNB) at 150 and 300 kg/ha, and combinations of the two, were studied for control of Sclerotium rolfsii prior to iris cultivation. Sclerotia buried 10 cm deep in soil were all killed by MB at 500 kg/ha; at greater depths higher doses were required. Bulbs harvested from PCNB- and PCNB + MB-treated plots were healthy; 75% of the bulbs in control plots were infected at harvest. When MB was used alone, the soil became re-infested (2-6% diseased plants). Bromide toxicity, correlated with the MB dose applied, appeared 41/2 months after planting; leaves yellowed and senesced prematurely. MB treatments also reduced bulb size, and residual phytotoxicity was found when the bulbs from treated plots were planted in the following year. © 1976 Springer Science + Business Media B.V.
