Other claims from this paper (9)
- Intervention effect Phorate granules placed with seed reduced carrot seedling emergence in mineral and peat soil.
- Intervention effect At 4.48 kg a.i./ha below the seed, carrot emergence was adversely affected in mineral soil.
- Intervention effect Phorate placed with seed in peat soil produced lower carrot plant density than placement below seed.
- Intervention effect Subsequent carrot yields were unaffected by the placement difference.
- Observation Larger carrot roots compensated for reduced plant density.
- Intervention effect All phorate treatments reduced carrot fly larval damage to carrot roots.
- Association Increasing phorate rate placed with carrot seed increased total residues in mature carrots on peat soil.
- Intervention effect Residues from 1.12 kg a.i./ha with seed were not significantly greater than untreated carrots.
- Intervention effect Residues from 2.24 kg a.i./ha below seed were not significantly greater than untreated carrots.
