Other claims from this paper (9)
- Intervention effect Azoxystrobin with mancozeb and mineral oil at 0.10 g a.i./liter controlled citrus black spot by more than 98 to 99% relative to an untreated control.
- Intervention effect Azoxystrobin with mancozeb and mineral oil at 0.15 g a.i./liter controlled citrus black spot by 99 to 100% relative to an untreated control.
- Intervention effect Azoxystrobin and mancozeb without mineral oil resulted in only 73 to 95%, 74 to 93% and 92.2 to 92.3% control of citrus black spot.
- Intervention effect Benomyl, mancozeb and mineral oil tank mixtures reduced citrus black spot by only 29%, possibly because of benomyl-resistant pathogen isolates.
- Intervention effect Azoxystrobin at 0.05, 0.075 and 0.10 g a.i./liter in tank mixtures with mancozeb was equally effective against citrus black spot, reducing it by more than 99%.
- Intervention effect Mineral oil was the only adjuvant that gave 100% clean exportable fruit when mixed with azoxystrobin and mancozeb.
- Intervention effect Sunspray 6E and Bac oil gave no difference in the degree of citrus black spot control when mixed with azoxystrobin and mancozeb.
- Intervention effect Mineral oil concentration can be lowered from 0.5% to 0.3% (vol/vol)/liter of water without loss of efficacy against citrus black spot.
- Recommendation Azoxystrobin at 0.075 g a.i./liter must be applied in tank mixtures with mancozeb and mineral oil for citrus black spot control.
