Influence of Liquid Smoke Cinnamon Against Attacks Leaf Rot Disease (Phytophthora Infestans) on Potato (Solanum Tuberosum L.)

Abstract

Shaped research on the effect of using liquid smoke cinnamon against late blight (Phytophthora infestans) on potato (Solanum tuberasum L.) has been conducted in the village of Gunung Tujuh Pelompek District of Kerinci regency in Jambi Province. The purpose of this study was to determine the effect of the use of liquid smoke against late blight (Phytophthora infestans) on potato and other effects related to growth factors and production of potato (Solanum tuberasum L). The experiments were conducted in the field using a randomized block design with 8 treatments and 3 replications thus obtained 24 experimental unit. Each experimental unit consisted of 35 plants. As the plant sample under observation for variable growth is as much as 5 samples and disease variables is the entire plant for each plot. The treatments were the use of multiple doses of liquid smoke for spraying are: A = non-treated liquid smoke (WAPer only), B = fungicide interval of 7 days, C = treated liquid smoke 25 cc/liter of WAPer alternating with fungicides, D = treated liquid smoke 50 cc/liter of WAPer alternating with fungicides, E = treatment liquid smoke 75 cc/liter of WAPer hose alternating with fungicides, F = treatment liquid smoke 100 cc/liter of WAPer alternating with fungicides, G = liquid smoke treatment of 125 cc/liter of WAPer alternating with fungicides, and H = treatment liquid smoke 150 cc/liter of WAPer. The data were analyzed statistically by F test if the F-test has a significantly different effect and then continued with Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results show that the use of different doses of liquid smoke influence of highly significant observation parameters, namely: plant height, length, and width of leaves, leaf number, and weight of tubers per plant, number of tubers per plant, tuber weight per plot, intensity rot disease and the percentage of leaf blight attack. Plants treated with the liquid smoke with a rate of 125 cc punctuated alternately with fungicides showed intensity and percentage of the lowest disease. It is advisable to do further studies with different doses and with no fungicide treatment on the season and a different location.
