<![CDATA[Red chili (Capsicum annuum L.) is a commodity that has high economic value, but the potential loss experienced in chili cultivation is also quite high, because chili is quite vulnerable to fruit fly pests. This study aims to determine the response of fruit flies to the use of pheromones derived from various kinds of fruit peels and flesh added with yeast (organic pheromones). This research took place on chili farmers' land located in the village of Tambak Langsat, West Ulin Platform, Banjarbaru City. This study used a randomized block design (RBD) with 11 treatments including the control. The results showed that the treatment given organic pheromones was able to trap fruit flies. Of all the pheromones that were most effective at getting lots of fruit flies was the chili pheromone (0.2 ml) with a catch of 25 individuals and for organic pheromones that were less effective was the mango pheromone (0.2 ml) with a catch of 4 individuals. The type of fruit fly B. dorsalis dominates of the four species with the Diversity Index (H´) of fruit flies being classified as moderate, namely 1.1082, the Dominance Index (D) being high 1 and for fruit flies dominating B. dorsalis.]]>

<![CDATA[Spodoptera frugiperda is the main pest that attacks corn plants, so it is necessary to control it. One of the control alternatives is using the biological agent Bacillus thuringiensis (Bt). In this study the use of biological agents B. thuringiensis bacteria against S. frugiperda larvae. This study aims to determine the ability of B. thuringiensis bacteria to control S. frugiperda on a laboratory scale. This study used a completely randomized design (CRD) with 4 treatments and 6 replications. The treatment used doses of 2 ml, 2.5 ml and 3 ml of B. thuringiensis bacteria and as a comparison, namely sterile water which acted as a control in this study. Mortality observations were made every 12 hours for 96 hours. Each replicate was infested with 10 S. frugiperda larvae so that 240 S. frugiperda larvae were obtained in each experimental unit. The results of this study indicate that the biological agent of B. thuringiensis at a dose of 3 ml has the pathogenicity ability to S. frugiperda mortality with a percentage of 23.3% and has the best lethal time value of 9.3 days to kill 50% of S. frugiperda.]]>

<![CDATA[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.]]>

<![CDATA[C. kyllingia is an annual weed that can cause problems because it can reduce the quantity and quality of cultivated plant production, so this weed needs to be controlled. Weed control with synthetic herbicides is currently more popular because its effectiveness can be seen more quickly. However, if synthetic herbicides are used for a long period of time, they will affect soil conditions. Therefore, an alternative weed control using liquid smoke from empty oil palm fruit bunches (TKKS) is needed. The research aims to determine the potential of TKKS liquid smoke in controlling the growth of sedge weed (C. kyllingia). The design used a 1 factor Completely Randomized Design consisting of 5 treatments and 5 replications with liquid smoke concentrations of 0%, 8.3%, 16.6%, 25% and 33.3%. Research shows that TKKS liquid smoke has the potential to be used as a natural herbicide because it has an effect on suppressing the growth of the C. kyllingia weed. The best concentration that can suppress weed growth is 33.3% liquid smoke.]]>

<![CDATA[Fall Armyworm (Spodoptera frugiperda) is an invasive insect pest that has a high appetite, causing damage and reduced yields in corn plants. One way to control these larvae is to use the biological agent Metarhizium anisopliae. The aim of this research was to determine the influence of several spore densities of the entomopathogenic fungus M. anisopliae on S. frugiperda. The design used in this research was a Completely Randomized Design (CRD) which consisted of 4 treatment levels of spore suspension density 107,108, 109 and a water control treatment as a comparison with 6 replications. Application was carried out on 3-4 instar larvae with an observation period of 12 hours for 4 days. The results of this study showed that the application of the biological agent M. anisopliae with a spore density treatment of 109caused the highest larval mortality of 76.7%. Lethal time (LT_50) for larval mortality caused by M. anisopliae is 2.80 days. From probit analysis, the Lethal Concentration (LC_50) value was 2.44 x 109 spores/ml.]]>

<![CDATA[Research has been conducted with the title Exploration and Identification of Fungus Causing Disease Sawi Pakcoy Plant (Brassica rapa L). This study aims to find out the types of diseases and symptoms that attack in pakcoy plants (Brassica rapa L). This research was conducted in Guntung Payung, Landasan Ulin District, Banjarbaru City, South Kalimantan (Field) and Agroecotechnology Production Laboratory of The Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. For field research conducted by visual observation of disease attack symptoms or by looking at the symptoms seen in plants in the field, followed by identifying disease-causing pathogens in the laboratory. Field sampling was randomly taken in four crop plots. Samples taken in the form of parts of plants affected by the disease. The results showed there are three types of mushrooms that attack the plant of mustard pakcoy, fungus found to be pathogenic and also parasites that cause mustard pakcoy to grow not optimally and also cause death. Fungus who attacked in each map is Fusarium sp., Phytophthora sp. and Curvularia sp.]]>

<![CDATA[One environmentally friendly alternative for weed control is to utilize cocoa plant waste (Theobroma cacao L). Can be used as a biological herbicide. The aim of this research is the effectiveness of the long fermentation time of bioherbicides from cocoa shells and beans in controlling weeds. This research used a non-factorial Randomized Block Design (RAK), consisting of 4 treatments (K (Control), M1 (7 days), M2 (14 days), M3 (21 days) and M4 (28 days)) with as many repetitions as possible. 3 times. The results of this research show that weed growth can be suppressed with cocoa bioherbicide from observation week 1 to week 3, with the highest poisoning score being 4 (Very severe poisoning; young leaves have an abnormal shape and color until they dry out and fall off until the plant dies). Symptoms of poison caused by biorherbicides include changes in leaf color from green to pale and eventually death.]]>
