Abstract

Research has been carried out on the use of botanical pesticides from yam seed extract against Spodoptera litura larvae. The aim was to determine the effect of yam bean seed extract as a natural pesticide on the mortality of armyworm pests and reduce the intensity of attacks on mustard greens. This study used one factor RAL with 6 treatments and 4 replications, as a control with two ingredients, namely chemical pesticides and water. Observation of mortality was observed every 6 hours for 3 days in the laboratory and observation of attack intensity for 7 days in the greenhouse. In each treatment, 10 S. litura larvae were invested so that in the experimental unit there were 240 larvae tested both for mortality and attack intensity. The results of the research on Jicama seed extract showed the highest percentage of mortality at a concentration of 15% of 37.5%, while the lowest percentage of attack intensity was at a concentration of 15% of 87.9%.

Abstract

Testing the effect of the extract of the plant Tegari (Dianella sp.) on non-target animals was carried out with the aim of knowing the dose that is effective in controlling rats but is still safe if consumed by nontarget animals. This research was conducted from March to April 2022 in Sawang Village, South Tapin Regency, South Kalimantan. The test used four doses, namely 120 grams/liter, 170 grams/liter, 220 grams/liter, and 270 grams/liter with four repetitions and three chickens in one repetition. The results of this study showed that there were still deaths with a percentage of 8.33% and the results of the ANOVA test showed that the effect of using the plant extract at the dose used did not significantly affect the mortality of chickens

Abstract

Bacterial wilt disease caused by Ralstonia solanacearum on tomato plants can reduce the quantity and quality, so it is necessary to control this disease. One of the controls that can be used is control using antagonistic agents. Bacteria Bacillus sp. and Pseudomanas fluorescens is an antagonist agent contained in PGPR which has the ability to suppress disease growth, increase plant root uptake of several nutrients and increase plant growth. This study aims to determine the effect of Bacillus sp. and P. fluorescens from bamboo roots in suppressing bacterial wilt disease of R. solanacearus in tomatoes. Using a Completely Randomized Design Method (CRD) consisting of 3 treatments, each treatment consisted of 6 replications so that 18 experimental units were obtained in vivo. Observations were made by measuring plant height, number of fruit, fruit weight and intensity of disease attack. The results obtained in this study indicate that the administration of Bacillus sp. and P. fluorescens were able to control bacterial wilt disease caused by Ralstonia solanacearum bacteria in tomato plants.

Abstract

This study aims to determine the ability of guava leaf powder (P. guajava L.) in controlling anthracnose disease caused by the fungus Colletotrichum sp. on eggplant (S. melongena L.). This research was conducted in March – July 2022. This study used a Completely Randomized Design (CRD) which consisted of 6 treatments, each treatment was repeated 4 times so that there were 24 treatment units and each replicate consisted of 5 plants, so a total of 120 plants . The treatments used were 0, 20, 25, 30, 35 and 40 g of guava leaf powder + 100 ml of distilled water. Based on the observed concentration of 25 g of guava leaf powder + 100 ml of distilled water (T2) it has the longest incubation period of 11.74 days with disease incidence and disease intensity of 18.49% and 3.66%, respectively

Abstract

The purpose of this study was to identify the types of arthropods and diseases in rice plants, especially those in Kusambi Hilir Village, Lampihong District. The method used is a survey method by taking arthropod samples, using insect nets and light traps, observing symptoms of rice plant diseases. The results of the study found that the number of arthropods in paddy fields near the rubber plantations was 219 consisting of 162 individuals (73.97%) pests, 43 individuals (19.63%) predators, 6 individuals (2.73%) parasitoids and 8 individuals ( 3.65%) other arthropods. The number of arthropods in paddy fields near the main road was 159 individuals consisting of 100 individuals (62.89%) pests, 45 individuals (28.30%) predators and 14 individuals (8.81%) parasitoids. The dominant arthropods and diseases in rice are Scirpophaga incertulas Walker and bacterial leaf blight. The diversity index of arthropods is categorized as low because a diversity index of 2.577 is obtained in paddy fields near the main road and (H') is 2.348 in paddy fields near rubber plantations.

Abstract

Anthracnose disease is caused by the pathogen Colletotrichum spp. which attacks cayenne pepper plants. This disease can reduce the quantity and quality of cayenne pepper fruit, causing losses. One of the existing sound technologies is Sonic Bloom. Sonic bloom is a sound wave technology with a certain frequency to determine the development of plant growth. There is very little research on plant diseases. This study aims to determine whether sonic bloom has an effect on anthracnose disease caused by Colletotrichum spp. The method used was Completely Randomized Design (CRD) consisting of 4 treatments, each treatment consisting of 6 replications so that 24 experimental units were obtained with 1 plant in each experiment carried out in-vivo. Observations were made by measuring disease incidence, plant height, number of fruit and fruit weight. The results obtained in this study showed that the sonic bloom treatment was able to reduce the percentage of anthracnose disease caused by the fungus Colletotrichum spp. on cayenne pepper plants. Sonic bloom has not been able to affect the height of cayenne pepper plants and inhibit the incubation period, but sonic bloom has been able to increase the weight of cayenne pepper fruit.

Abstract

Color traps are one way to control insects around plants. This research aims to determine the type of color and height of the trap on insect attraction to chili plants in 2 generative phases and vegetative phase. This research took place in Bentok Darat Village, Bati-Bati District, Tanah Laut Regency, South Kalimantan Province from May to July 2022. The method used was (RAL) with 2 factors and 3 repetitions. The first color factor is W1: Yellow, W2: Green, W3: Red and the second factor is the height of T1: 30 cm, T2: 60 cm and T3: 90 cm. The results of this research were that yellow traps had the highest number of insect catches, namely 1,634, and at a height of 30 cm, yellow traps had the highest number of catches, 362. From this research, the total number of insect catches obtained was 3,676 individuals. In the vegetative phase there were 1,629 insects and in the generative phase there were 2,047 insects.

Abstract

This research aims to determine the impact of eco enzyme application on microbial diversity in the rhizosphere of shallot plantations on peatlands. This research used descriptive techniques with a purposive sampling method, consisting of 4 treatments, namely control (without eco enzyme treatment) and 3 treatments of eco enzyme solution with doses (0.2 ml, 0.6 ml, and 1 ml/200 ml water) with 5 repetitions. The identification results showed that there were 65 microbial isolates, of which 28 fungus isolates consisted of 9 fungal genera, namely Trichoderma spp., Penicillium sp., Acremonium sp., Mortierella spp., Humicola sp., Fusarium spp., Aspergillus sp., Culvularia sp. , Pythium spp. and 37 bacterial isolates consisting of 29 gram-positive bacterial isolates and 8 gram-negative bacterial isolates. The results of the research show that the application of eco enzyme has an impact on microbial diversity in the rhizosphere of shallot plantings on peatlands. The diversity of microbial types ranges from 0.9 – 1.4, including in the low – medium category. The richness of microbial species ranges from 0.9 – 1.7, which is included in the low category. The evenness of microbial types ranges between 0.8 – 1.0, including the low category, and the dominance index ranges between 0.3 – 0.5, including the none dominate category.
