The rust pathogens (Puccinia spp.) affect many cereals, pulses and sugar crops causing a major threat to crop production
and productivity throughout the world. The sugarcane crop is being affected by Puccinia melanocephala and P. kuehnii
causing brown and orange rust respectively. Sugarcane rust is an important constraint in popularizing the new and high
potential varieties due to its appearance on the foliage. Under the changing climatic conditions many popular cultivars are
showing rust infection from mild to severe form depending on the weather conditions during the crop seasons. Being an
obligate pathogen, the rust is present on sugarcane throughout the year but the appearance and severity is highly influenced
by the weather parameters such as temperature, relative humidity and the physiological maturity of the crop. Trapping the
uredospores using Vaseline coated microscopic glass slides helped to determine the inoculum load at various time intervals
in the air. The uredospores can be observed with the help of Foldscope, which broadens the scope of detection of uredospores
without depending on the compound microscope in remote areas. By connecting with the mobile phone, the spores can be
photographed and digital pictures can be shared for further confirmation. The frequency and quantity of the uredospores
trapped will help in quantifying the spores in the field for management of sugarcane rust well in advance before the appearance of the symptoms in hot spot areas. This simple tool will be a boon for detection of rust spores in the field during the
latent period before the appearance of the symptoms thus enabling management of rust in time.
