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

For any crop-protection agent, an efficient formulation is a necessity to translate laboratory activity into adequate field performance. There are particular challenges to be faced in formulation of biological control agents, because the active ingredient is a living organism that must be kept relatively immobile and inactive while in storage, but quickly resume its  normal metabolic processes once applied to the target site. The objective of the research was  to study survival of Pseudomonas putida strain Pf-20 in various formulations at the storage  time and germination. The twelve formulations include carriers, additives and concentration  of Pf-20. The efficacy of various formulation in maintaining the population of Pf-20 in storage was assessed. The research result showed that population of Pf 20  in the formulation  number seven was the highest, with the combination peat+talc, CMC+arginin and  concentration of Pf[20 10^10 CFU/ml. In peat+talc, CMC+arginin, Pf-20 10^10  CFU/ml based formulation the bacteria survived even up to 84 days of storage although the population declined. In all formulations, population of Pf-20 increased at the time of seed germination. At the time of seed germination, formulation number seven was the highest too.

Abstract

Formula with active ingridient of fluorescent pseudomonads and its influence on wilt disease development of pepper. The purpose of this study was to synergize organic fertilizer with biopesticides of fluorescent pseudomonads 122 to be the best formula to increase the resistance of pepper plants to wilt disease. The study used a completely randomized design (CRD), which consisted of four treatments. The treatments were forms of active ingredient formula of fluorescent pseudomonads (powder, pellet, granule, and liquid). The effectiveness of the formula in suppressing development of the disease was measured by observing the incubation period, index of the disease and discoloration of vascular tissue of pepper. The results showed that the disease incubation period of plant treated with liquid and powder formula was longer than formula with granule and pellet. Plants treated with powder formula showed the lowest disease index compared to control, liquid, pellet and granule formula. Disease index and discoloration in vascular tissue was also of the lowest value when the plants were treated with powder formula. This result indicate that active ingredient of fluorescent pseudomonads formulated in powder was the most effective to inhibit the development of wilt disease on pepper caused by Fusarium sp. and Ralstonia solanacearum.

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
