Abstract
The staple food of the Indonesian population is rice, and the increasing demand for rice follows the increase in population, and one of the obstacles to increasing production is crop failure caused by rice leaf blight. Leaf blight is one of the important diseases that cause yield loss of almost 70%. The purpose of this study was to determine the effect of concentration and interval of application of tobacco leaf biopesticides on the development of leaf blight in Ciherang rice varieties. This study was designed using a factorial completely randomized design, the first factor was the concentration of tobacco leaf biopesticides which consisted of 4 levels, namely 0 ml/l, 1 ml/l, 2 ml/l, and 3 ml/l, the second factor was interval Giving consists of 3 levels. i.e. every 5 days, 10 days, and 15 days. The parameters of the development of rice leaf blight observed were the number of grains per plant, the percentage of attacks and the intensity of leaf blight attacks. The results showed that the highest number of grains per plant, the lowest attack percentage, and the lowest attack intensity were in the T3D1 treatment.
