Control of the cabbage aphid (Brevicoryne brassicaeL.) with some systemic materials

Abstract

SummaryThe control of the cabbage aphid on cruciferous seed-crops offers a special field for the aerial application of systemic materials.In an experiment using Ekatin, Megatox and Metasystox at 4 oz active material per acre, and Lebaycid, Metasystox and Rogor at 8 oz, results were tested by Duncan's test. Megatox, Metasystox (8 oz), Ekatin and Metasystox (4 oz), all gave satisfactory control, in that order of merit. Megatox, however, is not available for commercial use at present in New Zealand.

Field Sprays for Control of Bean and Cabbage Aphids

“…After 14 days, however, fluoroacetamide (A), demeton-methyl and phosphamidon-treated plots were significantly less infested than those treated with dimethoate, which appeared to be less persistent than the other sprays, although no material was effective up to 21 days after spraying. These results agree with those of Lowe (1960) who found low volume sprays of fluoroacetamide (A) at 4 oz a.i. per acre, and demeton-methyl at 8 and 4 oz., gave satisfactory control of B. brassicae on kale in New Zealand; dimethoate at 5 oz a.i.…”

Trichosurus vulpecula (brushtail possum)

“…The compound has been tested on and used in the field for aphid control in several countries (Atzert 1971, Dunning andWinder 1960). Lowe (1960) used 1081 (similar properties to 1080) on cabbage…”
