Other claims from this paper (18)
- Intervention effect Soil drenches in sands and sandy soil produced greater insecticide residues than in other soils.
- Intervention effect Soil drenches in sands and sandy soil produced longer periods of insect kill than in other soils.
- Observation Phosdrin pea aphid control lasted 2 days in loam and muck.
- Observation Phosdrin pea aphid control lasted 19 days in sand.
- Intervention effect Demeton was most effective in sands and least effective in muck.
- Intervention effect Phorate was most effective in sands and least effective in muck.
- Intervention effect Schradan was more effective in treated sands and sandy soils.
- Observation Schradan yielded low insect mortality at the 24-hour count.
- Intervention effect Peas absorbed more Isolan from muck than from either loam soil.
- Method / resource Anticholinesterase and insect bioassay results for Isolan and Phosdrin treated peas were comparable.
- Observation Peat bound 127 micrograms of Phosdrin per 100 grams of soil.
- Observation Heavy loam soils bound 10 to 27 micrograms of Phosdrin per 100 grams of soil.
- Observation Sandy soils bound 3 to 8 micrograms of Phosdrin per 100 grams of soil.
- Association Phosdrin soil binding correlated positively with base exchange capacity.
- Association Phosdrin soil binding correlated positively with organic matter content.
- Association Phosdrin soil binding correlated positively with nitrogen content.
- Mechanism The authors attributed insecticide binding primarily to soil organic matter.
- Association Other soil chemical and physical properties did not correlate with Phosdrin binding.
