The tomato (var. sumberson) is highly susceptible to diseases caused by microorganisms as well as pest infestations; as a result serious loss is caused thereof in the production of those crops. On the background of these facts, the research was focused on controlling the diseases through the selected treatments with the objectives of evaluating the efficacy of Lantana camara extract, Balanites extract and their combinations to assess on controlling the pest/disease incidence and severity in tomato field conducted in Hamelmalo Agricultural College. The experiment was conducted in RCBD with the treatments: Lantana flowerextract, foliar fungicide (Mancozeb), soil fungicide (Sulphur dust), and Balanites seed kernel extract, combinations of fungicides with Lantana extract and Balanites extract and Control. The insect pests i.e. Leafminer, Whitefly and African boll worms; two bacterial diseases: Bacterial rot and Bacterial speck; one fungus: Early blight and a viral disease were recorded in the field during the study period. Aqueous extract of Balanites seed kernel and Mancozeb, after treatment, also showed good control on both early blight and soft rots. There was a significant difference among all the treatments in every disease recorded in comparison to control. In the case of disease severity, the treatments of T1, T2 and T4 showed drastic decrease in the early blight whereas T6, T5 and T1 showed drastic reduction in soft rots on tomato. A drastic control of Leafminer was noticed by T2 and T6 from 18.4% to 7.5% and from 19.3% to 11.3% before and after treatments, respectively.
