Other claims from this paper (11)
- Intervention effect Petroleum oil sprays did not affect rind colour at either location.
- Intervention effect Sprays had significant but inconsistent effects on other fruit-quality traits.
- Association Higher oil distillation temperature and application rate tended to decrease Brix.
- Intervention effect Oil sprays did not significantly affect yield at Kulnura.
- Intervention effect At Griffith, 2% sprays of 238 oil reduced fruit number.
- Intervention effect April 2% oil sprays tended to yield less than November or February sprays at both locations.
- Intervention effect Effects of 3.2% total-concentration sprays varied.
- Observation Only 238 oil was considered potentially phytotoxic.
- Recommendation Authors advise against 238 oil above 2% from March to November or in consecutive years.
- Recommendation Authors consider consecutive-year use at 1.2% from late spring to early autumn acceptable.
- Association Location differences in oil phytotoxicity appear related to summer and early-autumn night temperatures affecting flower initiation.
