Abstract

ABSTRACT Utilization of Trichoderma sp. and Grafting to Controlthe Mayor Diseases of Tomato (Licopersicum esculentum Mill.) in Bangli Village, Baturiti, Tabanan Control of plant diseases is one of the constraints in the cultivation of tomatoes. Control method performed by farmers generally use synthetic pesticides, however that cause environmental pollution. The use of Trichoderma sp. and grafting is an environmentally friendly technology in controlling plant diseases. The purpose of this study was in order to determine the ability of Trichoderma sp. and the grafting between the eggplant EG203 strain as rootstock and scions tomatoes as to control major diseases and improve tomato production. This study used a factorial randomized block design with six treatments and four replications.Diseases were found in field tomatoes are late blight (Phytophthora infestans) and yellow curly leaf disease (Tomato Yellow Leaf Curl Virus). Statistical analysis showed that Trichoderma sp. and grafting can reduce the disease severity of leaf blight and increase the production of tomato plants, but was unable to control the disease yellow leaf curl. Average of disease severity of leaf blight on grafting with screen and Trichoderma sp. was lower (61.11 and 62.03%) when compared to treatment without grafting and without Trichoderma sp. (82.99 and 75.47%). Average of yields on treatment grafting with screen and Trichoderma sp. was higher (3912.50 and 3822.22 g/plant) compared to treatment without grafting and without Trichoderma sp.

Abstract

ABSTRACT Study of Resistance of Tomato Lines to Late Blight Disease (Phytophthora Infestans) Indonesia is one of the tropical countries with high potential of horticulture, especially tomato. To produce high quality and quantity of tomato the one problem is plant diseases. The most cereus disease was reported as late blight, it is caused by Phytophthora infestans. P. infestans is commonly out break in high land area, with more than 1000 m acl.  The late blight can reduce the production of tomato or in some case make the loss of yield. To control the disease the farmers have been used the chemical fungicide. However the chemical fungicides have many negative impacts. Therefore to control the disease the one of possible way is using resistant plant. On the other hand the tomato has been planted in Indonesia has not resistance by the late blight. Base on that, the experiment to select some resistant plant was conducted. The experiment was done in high land area in Bukitcatu and Pancasari (Bedugul area 1200 m acl).  The experiment was conducted used 16 lines and 4 varieties. The15 lines were imported from AVRDC and 1 line and 3 varieties were come from IVEGRI and 1 variety is local used by farmer. The result shown the most resistance lines are AVTO 0922, AVTO 1122, and AVTO 1143 base on the disease incidence and severity observation. The AVTO 0922, AVTO 1122, and AVTO 1143 were significant difference with another lines and varieties. Keywords: Tomato lines, Phytophthora infestans, resistant plant
