Grains and field crops
Field trials done in 1974 showed that phenamiphos could be used to control Anguina sp. and suggested that low rates may be effective with critical timing of applications. These possibilities were investigated in 1975. Locality - Katanning - F. Quartermaine and c. Butterworth. Gnowangerup - J. Griffith. Tables 1 and 2 show the absolute levels of nematodes in ryegrass seed and the density of nematodes per unit area of pasture after treatment with phenamiphos. All rates of nematicide reduced the level and density of nematodes; the highest rate being slightly more effective. The spray schedule including sprays in July and August was superior to the schedule excluding the August spray. A single spray in June did not control Anguina sp.
