Abstract

Herbicides are a substance or chemical compound used to inhibit growth or kill plants. Herbicides are toxic to weeds or pests as well as cultivated plants. The impact of using the herbicide paraquat causes some microbes to become more resistant and has the potential to be used as a paraquat biodegradation agent. Indigenous yeast is one of the microbes that can be used as a biodegradation agent because it is resistant to the environment. For this reason, This research aimed to investigate the indigenous yeast isolated from the potato field in Sumberbrantas village, Batu City as a bioremediation agent for paraquat herbicide residues.The sampling was carried out in the potato field of Sumberbrantas, Batu City, which in routine maintenance uses a herbicide with active paraquat (1,1 dimethyl -4, 4-bipyridinium dichloride).The isolation results obtained 6 isolates of indigenous yeast which had the potential as biodegradation agents for paraquat. Treatment of yeast isolates MB 1, MB 3, MB 4, MB 6, MB 7, MB 8 at concentrations of 250, 500, 1,000 and 2,000 paraquat were able to survive with a growth percentage of 75-100%. At a concentration of 5,000 Isolated yeast decreased with a growth percentage of 50-75% and MB 1 isolate with 10,000 ppm concentration still survive with a growth percentage of 1-25%. The highest biodegradability ability of yeast was in MB 1. The identification of MB 1 isolates based on molecular characters have similarities in the basic structure of 98.89% with Geotrichum silvicola UFMG 354-228S isolates with accession number NG_0606221.1.

Abstract

Rice, as a staple food, is widely produced across Indonesia. However, bacterial leaf blight (BLB) in rice is caused by Xanthomonas oryzae pv. oryzae (Xoo) has been reported to cause significant crop yield losses. The continuous use of chemical bactericides to control BLB is not environmentally sustainable. This study investigated the potential of the Binahong plant as a botanical pesticide to suppress the growth of Xoo bacteria. Binahong is readily available in Indonesia and can be propagated generatively and vegetatively. The research employed a Completely Randomized Design (CRD) experimental method to evaluate the effectiveness of Binahong leaf extract against Xoo pathogens in vitro at various concentrations (0.5%, 1%, 1.5%, 2%) alongside positive and negative controls. In-vivo observations were made on several parameters: seed germination percentage, disease incidence, incubation period, and plant length. Data analysis revealed that Binahong leaf extract inhibited the growth of Xoo bacterial colonies in vitro at all tested concentrations (0.5% to 2%). Furthermore, soaking rice seeds in Binahong leaf extract was effective in vivo at all concentrations, demonstrating significant differences compared to the negative control and no significant differences compared to the positive control.

Abstract

Anthracnose disease (Colletotrichum gloeosporioides) is one of the important diseases in shallots. Generally, farmers use synthetic fungicides. Thus, Siam weed (Chromolaena odorata) leaf extract can be used to reduce it because it has antifungal compounds. This study aimed to examine the effect of siam weed leaf extract on the growth of C. gloeosporioides and its antifungal compounds. This research used a completely randomized design (CRD). It would be continued with the SRD test at the 5% level if the result was significantly different. Treatment consisted of 0, 2, 4, 6, 8, and 10% Siam weed leaf extract with four replications. Bioactive compounds in siam weed leaves were tested by the UPT Herbal Materia Medica Batu Laboratory and Chem-Mix Pratama Laboratory, Yogyakarta. Probit analysis was also used to obtain the LC50 value. The results showed that 10% concentration was the most effective treatment because it produced a fungicidal effect on C. gloeosporioides. However, a 2.09% concentration of siam weed leaf extract was able to cause 50% of C. gloeosporioides' mortality. In addition, siam weed leaf extract contains antifungal compounds, such as tannins, phenols, flavonoids, alkaloids, and saponins.

Abstract

This study investigated the potential of the fungi Trichoderma viridae and Trichoderma harzianum in degrading the fungicide mancozeb. The research was conducted from May to October 2021 at the Plant Diseases Laboratory and Toxicology Laboratory, Department of Pests and Plant Diseases, Faculty of Agriculture, Universitas Brawijaya. The study comprised three stages. The first stage involved a preliminary test to assess the ability of T. viridae and T. harzianum to grow in media containing mancozeb-based fungicides. The second stage focused on evaluating the degradation of mancozeb using a bioassay, with the primary observation parameter being the biomass of T. viridae and T. harzianum. In the third stage, the mancozeb degradation process was assessed in vitro, with the observation parameters including the diameter of the pathogenic fungus Fusarium sp. and the percentage change in its diameter. Results demonstrated that T. viridae and T. harzianum could grow in media contaminated with mancozeb up to a concentration of 2 grams per liter. Furthermore, both fungi showed potential in degrading mancozeb, as evidenced by the increased growth of Fusarium sp. in treated media. It indicates that the application of T. viridae and T. harzianum reduces the toxicity of mancozeb. A t-test revealed that while there were differences between T. viridae and T. harzianum in their ability to degrade mancozeb, these differences were not statistically significant.

Abstract

Rice is one of the food crops that is a basic need for the people of Indonesia, but rice production in Indonesia is unstable every year because of various factors, one of which is plant diseases, such as Bacterial Leaf Blight (BLB) caused by Xanthomonas oryzae pv. oryzae bacteria. Active ingredients that can be used to control bacteria are copper-based active ingredients. In addition, increasing the concentration or adding surfactant in pesticide formulations can increase the effectiveness of active ingredients. This research was conducted at the Plant Disease Laboratory, Plant Pests and Diseases Department, Faculty of Agriculture, Universitas Brawijaya and Ketangi Hamlet, Tegalgondo Village, Karangploso District, Malang Regency. The In Vitro research design used a complete randomized design (CRD) and the In Vivo used a randomized complete block design (RCBD)consisting of 7 treatments and 4 replications. The parameters observed were inhibition, intensity of BLB, phytotoxicity, yield, and efficacy level. The results showed that treating copper oxide 60 WP+Surfactant, copper oxide 60 WP, copper hydroxide 80 WP+Surfactant, and copper hydroxide 80 WP effectively controlled bacterial leaf blight. While the treatment of copper oxide Zn 60 WP and copper oxy sulfate 345 SC was ineffective in controlling BLB. Each treatment of copper-based active ingredients at a dose of 2 grams and 2 mL did not show symptoms of phytotoxicity.

Abstract

Early Blight disease is an important disease of tomato plants caused by the fungus Alternaria solani. This disease attack can cause a decrease in production yields up to 78%. Control efforts using synthetic fungicides continuously can cause new problems for the environment. This research was conducted to determine the effect of fungicide applications with active ingredients Pyraclostrobin+Fluxapyroxad and the addition of biological agent Pseudomonas fluorescens on early blight disease and growth of tomato plants. This study consisted of in vivo and in vitro studies with observation parameters in the form of compatibility of bacteria with fungicides, fungicide inhibition, disease intensity, level of efficacy, and growth of tomato plants. The results showed that the combination of synthetic fungicide and Pseudomonas fluorescens was classified as compatible and effective in controlling Alternaria solani and able to support the growth of tomato plants. Combination treatment can reduce the use of synthetic fungicide by 25% of the recommended dose and is able to give results that are not significantly different from the recommended dose of synthetic fungicide treatment.
