The problem of tomato diseases and use of pesticieds on the floating island cultivation in inlay Lake, Nyaungshwe township, were sureyed in September 1995. Disease survey was conducted onthe farms of six sample village inInlay and infive storehouses inNyaungshwe. Use ofpesticides for tomato cultivation on floating islands, was surveyed by using a strucĀ¬ tured questionnaire to the growers.
Five fungal diseases and one bacterial disease were found infecting tomato plants. Among them altemaria leaf spot and fruit rot, locally named as "Mhetapaut", caused by Alternaria tenuis was found to be the most serious disease .Disease incidence, percentĀ¬ age of diseased plants, found was 100% in all the floating island s under obseruation. Disease incidence on fruits in storehouses was found to range from 19.42% to 57.73%. The longer the duration was in storehouse the higher the disease incidence occured.
The disease could not be differentiated from an insect damage by almost all the growers. Eight fungicides and 19 insecticides were used and dasages were found to be misused. The mixtures of 2 to 5 fungicides and I or insecticides were applied and suitable fungicides or insecticides.could not be used. During the epidemic outbreak of this disease, 20 to 30 sprayings were administered ina growing season. Use of glove, mask or other protective clothing were not used. The most serious pest on tomato plants was red spider mites which caused total loss of the crop insome areas in 1988and 1989.The most severe infection ofthe "Mhetapaut" disease occurred in 1995 resulting in 30 to 70 percent ofyeild loss.
