Abstract

The development of biopesticide formulas is carried out by optimizing the use of natural media materials. The formula is made easily, cheaply, and can still maintain the viability of bacteria. This study aims to determine the effect of various formulas and storage containers on the viability of Pseudomonad fluorescent Pf-122. Eight kinds of formulas include; 1) Non-hydrolyzed rice crab at a dose of 400 (K400), 2) at a dose of 200 (K200), 3) Hydrolyzed papaya rice crab at a dose of 400 (KP400), 4) at a dose of 200 (KP200), 5) Pineapple hydrolyzed rice crab with a dose of 400 (KN400), 6). at a dose of 200 (KN200), 7) Media King'S B at a dose of 400 (KB400), 8). at a dose of 200 (KB200). The formula is stored in a plastic and paper storage container. Population dynamics were observed at 1-week intervals. In the paper container, at week 1, the highest bacterial population was in the KP 400 and K400 formulas. At weeks 3 to 8, the population experienced a very rapid decline in all formulas, except for the KN400 formula. In the KN400 formula, at weeks 2 and 3, the population reached 107 CFU / ml and experienced a slow decrease until week 8 (population 101CFU / ml). In plastic containers, at week 1, the highest bacterial population was in the formula KB200, K200, and KP400. At the 3rd to 8th week of observation, the population experienced a rapid decline in all formulas, except for formula K400. In the K400 formula, starting from weeks 2 and 3, the population reached 106 CFU / ml and decreased until the 8th week (population 103CFU / ml). As for the KN400 formula, it can still last until the 7th week with a population of 102 CFU / ml. The longest survival rate of Pf-122 bacteria in the two storage containers was the KN400 formula. The best survival time of Pf-122 bacteria (long-lasting time and high population) is the formula of rice crab with a dose of 400 (K400) in a plastic container.

Abstract

One alternative for suppressing disease and promoting plant growth is to use the formula for biological agents. The research aims to determine the best formulation of Pseudomonad fluorescent Pf-122 and to determine the right application time in stimulating the growth of chili plants. The formula is made by mixing bacterial active ingredients with semi-natural media of rice crab by hydrolyzing using pineapple and papaya, as well as organic fertilizer. The study used 2 treatment factors. The first factor is the type of formula consisting of control using only Pf-122 (F0), Pf-122 + K (rice crab) (F1), Pf-122 + KN (rice crab by hydrolyzing using pineapple) (F2), Pf-122 + KP (rice crab by hydrolyzing using papaya) (F3). The second factor is application time; watering five days before planting and watering while planting. The results showed that plant growth, namely plant height, number of leaves, root length, and root weight did not differ statistically significantly from all treatment types of application. When viewed from the time of application of the formula, there is also no difference in the growth of chili plants. However, when viewed from the average value, the control without formula tends to show a lower growth value compared to that given the formula. In the generative growth phase, which is when the flowers appear, the chili plants are given a formula faster than without the formula. Application for all types of formulas, the time of occurrence of flowers is not significantly different. The number of Pf-122 populations in the rhizosphere decreases and increases are unstable in all formula applications. The high Pf-122 population in the rhizosphere does not show high chili growth either

Abstract

Fruit rot is one of the important diseases in cocoa fruit, which is caused by Phytophthora palmivora. Farmers often control these pathogen using chemical pesticides. However, this method has a detrimental impact on the environment and health. More environmentally friendly fruit rot disease control can use biocontrol agency. Bacillus sp. is one of the biocontrol agents that is able to produce antibiotics that can inhibit the growth of pathogens, especially soil-borne pathogens and have the ability to colonize plant roots. The purpose of this study is to determine the potential of Bacillus sp. in inhibiting the growth of the pathogenic fungus Phytophthora palmivora in vitro. This study used two experimental factors, type of isolates Bacillus sp. Ba-6 isolate, Ba-9 isolate, Ba-12 isolate, Ba-15 isolate, and Ba-17 isolate and the concentration of Bacillus sp. (106 cfu/ml and 109 cfu/ml). The parameters observed were the inhibitory power and the mechanism of inhibition of Bacillus sp. against Phytophthora palmivora. The results of the best in vitro inhibition test on Ba12K2 treatment with an inhibition of 61% with an inhibitory mechanism, namely antibiosis, as evidenced by the presence of zones of inhibition and swelling of the hyphae.

Abstract

Cavendis banana cultivation can use tissue culture as one of the developments of cultivation in the era of disruption. However, the results of tissue culture are very susceptible to attack by nuisance organisms during acclimatization to plant culture. The control carried out against the attack of plant-disturbing organisms in addition to using fungicides and insecticides, also applies preventive control. The purpose of this study was to determine an effective and smart way to control pests and diseases in tissue cultured Cavendish banana seedlings. Preventive control of pests and diseases using the method of thinning the seeds and soaking the seeds with fungicides. Data analysis was carried out using descriptive and parametric data. This study was conducted using a completely randomized design (CRD) with four control treatments. Each treatment was repeated 4 times. The control treatments carried out consist of: Control (A), preventive control (B), chemical control (C), and a combination of preventive and chemical control (D). The results of the control carried out showed that the combination of preventive and chemical control treatments gave significant results in inhibiting the attack of pests and diseases of Cavendish banana seedlings from tissue culture.

Abstract

Biological agent Bacillus sp. Based on the results of previous research, direct use of isolated microorganisms BCZ14, BCZ16, and BCZ20 was able to suppress Fusarium wilt disease. However, Bacillus sp. formulations in suspension form are less effective when applied in the field. This research focuses on analyzing the viability of three isolates of Bacillus sp. against several combinations of bioencapsulation coating materials. The experimental design used was a completely randomized design with a combination of treatment of three isolates and three types of coating materials, namely sodium alginate (B1), carrageenan (B2), and chitosan (B3) each 2%. Each treatment combination was repeated five times. Based on the experiments that have been carried out, the bioencapsulation formulation using 2% chitosan coating material was able to maintain the viability of the three isolates of Bacillus sp. BCZ14, BCZ16, and BCZ20. The population density of the three isolates of Bacillus sp. persisted consistently from the first week to the last week of observation. Therefore, the 2% chitosan coating material can be said to be able to maintain the viability of Bacillus sp. within six weeks.
