The Jurnal Proteksi Tanaman Tropis (Journal of Tropical Crops Protection = J. Trop. Crop Prot.) (ISSN: 2716-1234) is a peer-reviewed and open-access journal devoted to publishing research papers in all fields of Tropical Crop Protection, including basic phytopathology, entomology, weed, economy, epidemiology, and other design-related fields. It aims to provide an international forum for the exchange of ideas and findings from researchers across different cultures and encourages research on the impact of cultural factors on design theory and practice. It also seeks to promote the transfer of knowledge between professionals in academia and industry by emphasizing research in which results are of interest or applicable to design practices.

Abstract

Sugarcane (Sacharum officinarum L.) is a sugar-producing plant and is a food commodity that is needed by the people of Indonesia. National sugar demands are increasing every year. The low productivity of sugarcane is due to the competition of weeds which can reduce sugarcane production. To achieve high productivity, it is necessary to pay attention to the varieties used because they require certain conditions in their management. The purpose of this study was to determine the effect of varieties and types of weeds on the initial growth of sugarcane. The study was conducted from September 2018 to December 2018. The study used factorial Randomized Block Design (RBD) with two factors and four replications. The first factor consists of 4 sugarcane varieties, namely: Bululawang (V1), Red HW (V2), VMC (V3) and PS 862 (V4). The second factor type of weed consists of 2 types, namely Cyperus rotundus (N1) and Amaranthus spinosus L. (N2). The results showed that (1) There was interaction between the varieties (V) and the weed types (N) in stem diameter parameters and number of tillers, the treatment V4N1 gives the best response to stem diameter 1,31 cm and 4,25 number of tillers; (2) The treatment of varieties (V) gives affects to stem diameter and number of leaves, the treatment V4 gives the best response 5,38 to number of leaves; (3) Types of thorn spinach weeds can reduce the initial growth of sugarcane.

Abstract

Rowopulo is one of the swamps in Gumukmas, Jember Regency with its unique soil in the form of peat soil that floats on water and by the community used for rice cultivation, whose production is influenced by the presence of Plant Pests, which is dominated by the Herbivod Arthropods. The presence of herbivorous Arthropods in the swampland rice ecosystem can be suppressed by the presence of useful Arthropod populations such as predators, parasitoids, and pollinators. Related to this, a study was conducted to find out the diversity of Arthropods found in swampy rice plantations. The study began with a land survey, then the determination and marking of observation plots on the map and matching these locations using GPS (Global Positioning System). Observations were made on plots that were made based on the extent of rice plants that were still in one stretch and the same irrigation flow. Each plot was observed ten times at 7-day intervals from rice plants aged 14 days after 77 days after planting. Arthropod sampling using sweep net method. Catching arthropods are put into vials of 5 ml size and then identified up to family level, and the diversity, evenness, and wealth index of the species is calculated. The results of research on swamp rice plants contained 37 families. Ten families act as herbivorous Arthropods, 15 families as predators, six families as parasitoids, one family as pollinators, and five families as detritivores. The highest diversity index in plot 1 was 2.95, while the lowest in plot 2 was 2.70, with the medium category for all observation plots. The magnitude of the diversity index is due to the dominance of only a few orders, such as Orthoptera and Diptera; the highest species wealth index in plot 3 with a value of more than 4 in the high category; Evenness index of all observation plots has a value of less than 1 with uneven categories.

Abstract

An important disease in eggplant is bacterial wilting caused by Ralstonia solanacearum. The aim of this research is to characterize the biochemical endophytic bacteria isolated from eggplant root (BEAT) and as an agent for promoting plant growth and controlling bacterial wilt disease in planta. This research was conducted at the Plant Protection Laboratory and screen house of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto. This research was conducted descriptively to test the biochemical character of BEAT and used a Complete Randomized Block Design (RCBD) in the in planta test with 4 treatments, 6 replications and 3 plants each treatment, so that 72 plants were tested. The treatment consisted of control (without endophytic bacteria) and 3 BEAT isolates. The results showed that the endophytic bacterium AKc isolate had the ability as a bacterium to promote plant growth by producing IAA phytohormones, phosphate solvents, enzymes producing proteases, cellulase, amylase, chitinase, and HCN, as well as increasing the root volume and fresh weight of plants respectively by 40, 42% and 31%, suppressing the disease intensity by 33.33% and able to suppress bacterial wilting the best on the AUDPC value that is 47.32% -day.

Abstract

The golden Apple Snail is one of the rice pest that damaging by shredding the leaves of young plant. The common control has some negative impacts on the environment, so that the application of phyto-moluscides becomes a solution forming environmentally friendly agriculture. Neem and areca nut are one of the raw materials that can be used to control golden apple snails. This study aims to determine the effect of the concentration of neem and areca leaf extracts so the result of the study can be information and recomendations for controlling golden apple snail. This study uses a factorial Completely Randomized Design method, the first factor is extract raw material consisting of neem leaf, areca nut, and combination, while the second factor is consentration 0.25 g/L, 0.50 g/L, 0.75 g/L and control, each treatment gets 3 replications. Extract was applied by direct aplication method. Observations are carried out every 12 hours for 96 hours after aplication. The observed variable is behavior change, inhibition of eating activity and golden snail mortality. Data was analyzed by ANOVA then continued whit Duncan’s advanced test. Based on the result on the parameters that have been tested, raw materials and concentration have the effect of changing behavior from the start of the aplication, inhibition of eating activity, even an increase in mortality of up to 100% in the treatment of areca extract and combination application.

Abstract

Bacterial grain rot disease in rice plant is a new disease in Indonesia. The disease can reduce rice production up to 40% in severe disease attack. Morphological and physiological identification of these pathogens can be useful as a strategy of disease control. Control of this disease using Agent Biological Control is a right step and eco-friendly. The research was conducted in July until November 2018 at Plant Quarantine Laboratory of Agricultural Quarantine Center Surabaya. Design of experiment used on pathogenic identification is descriptively and analytically while in strategy of diseases control used are Randomized Complete Design method of single factor as many as 5 treatment of Bacillus spp. such as; Ba1: Bacillus spp. isolate 1, Ba2: Bacillus spp. isolate 2, Ba3: Bacillus spp. isolate 3, Ba4: Bacillus spp. isolate 4, and Ba5: Bacillus isolate spp. 5. Research result showed that the pathogen causing bacterial grain rot in Rice is Burkholderia glumae with bacterial characteristic are Gram negative, aerobic, not fluorescent on Kings B medium, mesophyll, isotonic, can hydrolysis arginine and can produce enzyme of gelatinase and (2) Bacillus spp. Isolate which consistent to inhibiting B. glumae in vitro is Ba-1 with a mean inhibition of 17.88 mm and a variety of resistance mechanisms, namely bacteriostatic and bactericidal Isolate of Bacillus spp Keywords: Bacterial grain rot rice; Bacillus spp; Burkholderia glumae
