Other claims from this paper (12)
- Intervention effect Uncontrolled P. citri populations reduced orange yield by 9, 6.6, and 11.4%.
- Intervention effect Fruit size increased by 2.3 and 2.1% at the first site under mite exposure.
- Observation The effects did not persist into later seasons.
- Intervention effect Higher fertilization increased total yield in years three and four.
- Intervention effect Higher fertilization decreased average fruit size in year three but not year four.
- Intervention effect Fungicide-nematicide treatments increased total yield and fruit size in years three and four.
- Intervention effect Growth regulators did not significantly affect total yield.
- Intervention effect Growth regulators reduced fruit size by 1.0% in year four.
- Intervention effect Differential irrigation had no consistent significant effect on yield.
- Intervention effect Increasing irrigation significantly increased fruit size at both sites.
- Association Mite-related yield losses were greater on nitrogen-stressed than conventionally or excessively fertilized trees.
- Observation Larger fruit under unsuppressed mite populations at least compensated for yield losses under the stated marketing conditions.
