Other claims from this paper (9)
- Intervention effect Schradan was the most effective insecticide tested against the walnut aphid.
- Intervention effect 0.5 pound of schradan per acre effectively controlled the walnut aphid for an entire year, except where the aphid resists phosphate insecticides.
- Intervention effect Dosages of 0.75 and 1.0 pound of schradan gave better control than 0.5 pound per acre.
- Recommendation Treatments must be made before the foliage hardens for satisfactory results.
- Association Vigor and thoroughness of application influence the effectiveness of treatment against walnut pests.
- Intervention effect Schradan exerts a suppressing action on other sucking pests of walnut.
- Intervention effect Schradan tends to increase the population of the calico scale.
- Intervention effect Schradan tends to increase the population of the European red mite.
- Mechanism Vigor of the trees and the fine quality of foliage on schradan-treated trees may partly result from a stimulus beyond aphid and pest control.
