Other claims from this paper (16)
- Intervention effect Dimethomorph was effective in controlling late blight in potato and tomato caused by metalaxyl-sensitive or metalaxyl-resistant isolates of Phytophthora infestans.
- Intervention effect Dimethomorph was effective in controlling downy mildew in cucumbers and melons caused by metalaxyl-sensitive or metalaxyl-resistant isolates of Pseudoperonospora cubensis.
- Intervention effect The fungicide did not affect zoospore discharge from sporangia of P. infestans.
- Intervention effect The fungicide strongly inhibited zoospore encystment, cystospore germination and mycelial growth of P. infestans in vitro.
- Observation Dimethomorph showed translaminar and local systemic activity in intact plants.
- Observation Dimethomorph failed to translocate from one leaf to another in either acropetal or basipetal direction.
- Intervention effect Dimethomorph applied as a soil drench failed to protect cucumbers against downy mildew.
- Intervention effect Dimethomorph applied in lanolin paste to the stem surface, but not to the hypocotyl, gave excellent control of both diseases in the foliage.
- Intervention effect Dimethomorph applied 1 day after inoculation partially protected potato against late blight.
- Intervention effect Dimethomorph applied 1 day after inoculation partially protected cucumber against downy mildew.
- Intervention effect Dimethomorph applied 1 day after inoculation reduced sporulation of the pathogen in both systems.
- Intervention effect Dimethomorph diminished sporulation of P. infestans and P. cubensis when applied to normally developed infected tissue.
- Observation Dimethomorph induced enhanced callose-encasement of haustoria of P. cubensis.
- Observation Dimethomorph showed remarkable persistence on foliage after excessive washing with water.
- Observation Dimethomorph showed high residual activity lasting for 9 days.
- Recommendation Dimethomorph seems to be a good candidate for controlling oomycete diseases in the field, especially where phenylamide-resistant fungal populations prevail.
