Other claims from this paper (14)
- Association Coffee rust control rose linearly with log fungicide concentration.
- Association Rust control increased with spray volume per acre.
- Intervention effect Adjusting spray residue through concentration was more effective and used less fungicide than adjusting volume.
- Intervention effect Upper-surface application matched lower-surface application in one trial at all concentrations and in another at higher concentrations.
- Association Differences in rust control among spraying machines correlated with leaf spray residue.
- Observation At equal rust control, the swirl-plate mist-blower used most fungicide per acre.
- Observation At equal rust control, the pneumatic hand-sprayer used least fungicide per acre.
- Observation The spinning-cage mist-blower nearly matched the low fungicide use of the hand-sprayer.
- Intervention effect Higher concentrations were needed to match the hand-sprayer’s heavy residues and rust control.
- Intervention effect Captan did not increase foliage density.
- Intervention effect Copper sprays directly influenced foliage density.
- Intervention effect March and April sprays most effectively reduced the amount of rust attack.
- Intervention effect Earlier sprays reduced the effect of later sprays.
- Intervention effect Reducing inoculum in January–March did not reduce the July–August rust peak.
