Other claims from this paper (11)
- Observation Teak leaf rust incidence was highest (85 %) at Badarpur, Faridpur sadar Thana, Faridpur District.
- Observation Teak leaf rust incidence was lowest (65 %) at Fatikchari Thana, Chattogram district.
- Observation Olivea tectonae infection caused severe to complete defoliation of young teak trees within 20-30 days of symptom onset.
- Observation This is the first record of leaf rust on teak in Bangladesh under natural field infection.
- Intervention effect Uredospore germination of teak leaf rust was better in the dark at 22 – 26 °C.
- Intervention effect Maximum uredospore germination of teak leaf rust (65.53 %) was observed at 95 percent RH compared with 65 percent RH.
- Observation No uredospore germination of teak leaf rust occurred at 65 percent RH.
- Intervention effect Diathene-M 45 showed the highest conidial inhibition of Olivea tectonae.
- Intervention effect Thiovit showed the lowest conidial inhibition percentage (21.38 %).
- Intervention effect Some chemicals inhibited uredospore germination of teak leaf rust in some cases.
- Recommendation Field trials should be undertaken using chemicals that are effective and economical against teak leaf rust.
