Other claims from this paper (7)
- Observation Some unsprayed old apple orchards bore good or fair crops practically free of scale.
- Association Vigorous, sappy growth was more infested and injured than slow, hardy growth.
- Association Trees in well cultivated, highly fertilized orchards were more likely to suffer scale attack.
- Association Slow-growing trees or trees in sod without much care were more resistant to scale attack.
- Association Trees infested while young and vigorous suffered more than trees first infested at bearing age.
- Observation Some previously treated and then abandoned infested trees later became practically free from scale.
- Mechanism The authors suggested nitrogenous fertilizers used for rapid growth may lessen resistance to insect attack.
