Abstract

ABSTRACT Entomopathogenic fungi are classified as a fungus that infects insect pests. Hyphae color that comes out of the insect's body depends on the type of entomopathogenic fungus that attacks it. The purpose of this research is to explore, isolate and identify entomopathogenic fungi that attack insect pests. Samples of dead insects were taken from vegetable crops in the highlands of Pagaralam City and the lowlands of Ogan Komering Ilir Regency. In addition, exploration is also carried out using insect bait methods. This method is carried out on soils taken from the highlands of the fencealam area and Pekanbaru area. Based on the results of entomopathogenic expolation in vegetable plants that infect insects in the field there are 2 types of fungi that attack the insect. Two types of entomapatogenic fungi were found to have characteristics, namely the first hyphal color is rather green which covers the entire body of the insect and the second is white hyphae. The fungus that attacks the insect, then isolated to the GYA media found two entomopathogenic fungi namely, Metarhizium sp. and Beauveria bassiana. Meanwhile, through insect bait using soil T. molitor larvae, one species of entomopathogenic fungus was found, namely Metarhizium sp. The most infected T. molitor larvae in the soil of origin of Pekanbaru in the 2nd and 4th weeks, namely, 21.90 and 29.33 tails. . Keywords: Entomopathogenic Fungus, Insect Pest and Tenibrio molitor

Abstract

Green stink bug (Nezara viridula L.) is a pod-sucking pest that can cause losses of up to 80%. The use of resistant varieties is an initial control effort that can be reduced or prevent losses due to green stink bug attacks on soybean plants. This study aims to determine the resistance of some soybean varieties to the attack of green stink bug (N. viridula). This study used a completely randomized design (CRD) with 5 treatments and 5 replications. The treatment used 5 soybean varieties namely V1 = Dega 1, V2 = Devon 1, V3 = Dena 1, V4 = Deja 1, V5 =. Detap 1. Each experimental unit is covered and invested 5 stink bug nymphs third instar. Based on the results, showed that Deja 1 and Detap 1 varieties are the best varieties to suppress the percentage of attacks and are included in the category of plants resistant to N. viridula, and have a significant affect to productivity higher than other varieties. Trichome density, hardness and skin thickness of pods significantly affect to the percentage of N. viridula attack so that it is included in the mechanism of antixenosis resistance.

Abstract

The study was aimed to determine the diseases in papaya plantations and to evaluate the effect of various disease control techniques against the intensity of disease in papaya plants in Pekon Way Nipah, Pematang Sawa District, Lampung. This research was conducted in October 2018 to May 2019 in the Biotechnology Laboratory, Faculty of Agriculture, University of Lampung and in Pekon Way Nipah, Pematang Sawa, Tanggamus, Lampung. This study was randomized block designed (RBD) with eight treatments consisting of control (K), biological spray agent (AHSP), manure plus biological agents (PK + AH), soil biological treatment agent (AHSI), bactericide spray (BSP)), manure (PK), solarization (SL), and tillage (OT). The study showed that the diseases that occurred on papaya plantations were suspected as powdery mildew, brown spots 1, brown spots 2, curly cladosporium, leaf curly, root rot and stem base. The treatment of manure plus biological agents reduced the severity of brown spot 1, brown spot 2, powdery mildew, and cladospsorium curling while solarization treatment suppressed the occurrence of root rot and base stem disease.

Abstract

This study aims to determine the effect of soursop leaf flour, lemongrass flour, kenikir leaf flour, lime leaf flour, and kluwih leaf flour on: 1) mortality, 2) damage to seeds, 3) shrinkage of seed weight, 4) appearance of adult C. analysts on soybean seeds in deposits and 5) laying eggs of C. analis imago female eggs, 6) probit analysis LT50. The experiment was carried out using a Completely Randomized Design (CRD). As treatments are: A) controls; B) soursop leaf flour in doses of 1 g, 2 g, and 3 g; C) Serai leaf flour with doses of 1 g, 2 g, and 3 g; D) kenikir leaf flour with doses of 1 g, 2 g, and 3 g; E) lime leaf flour with doses of 1 g, 2 g, and 3 g; and F) kluwih leaf flour with doses of 1 g, 2 g, and 3 g. Each treatment uses five replications. The observed parameters were analyzed by "F" test variance then if it was significantly different to find out the difference in the effect of treatment, an Tukey HSD Test was conducted at a level of 5% distrust. The best mortality results using the treatment of soursop leaf flour dose 3 g on 5 days amounted to 1.80 tails; 1 month is 6.60; 2 months totaling 13.40; and 3 months totaling 11.20. The results of the observation of the number of eggs produced by C. analis the best analyst was the treatment of soursop leaf flour dose 3 g on 5 days amounting to 139 items, 1 month 119.20 items; 2 months 91.20 items; and 3 months 72.20 items. The best imago observation results were treatment of soursop leaf flour dose 3 g at 1 month amounting to 132.20 tails; while at 2 months there were 79 heads. The best observation of seed damage and shrinkage of seed weight was the treatment of soursop leaf flour with a dose of 3 g, in the damage of seeds of 67.40 grains of seed damage; while the seed weight is reduced by 17.94 g. The results of the best analysis of Probit LT50 were treatment of soursop leaf flour with a dose of 3 g because it could kill 50% of the population C. analis with a relatively short time were 9 days after treatment.

Abstract

Ginger (Zingiber officinale Rosc.) Is one type of rhizome plant commonly used as a medicinal plant or spice. The rhizome is aromatic and has a distinctive odor used by the community to be used as spices, cooking ingredients and medicinal sources. So far the results of ginger production have not been able to meet people's consumption needs due to a decrease in ginger production at the main ginger development center (West Java). One of the main constraints of ginger cultivation is the attack of bacterial wilt disease caused by the bacterium R. solanacearum. One effort that can be done in tackling bacterial wilt in ginger plants is by using clones that are resistant to bacterial wilt disease of R. solanacearum. The experimental design was carried out using factorial Completely Randomized Design, using ginger clones and the application of R. solanacearum bacteria. This design consists of 6 treatments and 4 replications. Each replication unit consists of 4 plants, so the total number of plants used is 96 plants. The experimental results were analyzed using regression correlation analysis on the parameters of disease progression, while on plant growth parameters using variance analysis and if there were significant differences then continued with Duncan Multiple Range Test (DMRT) with a confidence level of 95%. The results showed red ginger clones including rather resistant criteria with a severity value of 25% while ginger empirical clones and elephant ginger clones were critically vulnerable with 75% severity values and 85.42%. Red ginger clones are more responsive to the infection of R. solanacearum bacteria so that the highest phenol content increases compared to other clones of 0.297 mg/ml, the phenol compounds that play a role in increasing plant resistance. In the variable growth of ginger emprit clone plants have a higher plant height and number of leaves compared to other clones, namely 43.83 cm and 15.44.

Abstract

Field experiments on the effectiveness and selectivity of herbicides use several active ingredients there were Sulfentrazone, Ethyl Pirazosulfuron, and Oxifluorfen with 2 varieties there were Peleton and Kanton tavi. The purpose of the study was to discover the most effective and selective herbicide active ingredients. The study was conducted from February to May 2019. This study used a randomized block design with 7 treatments, namely A (Kontrol), B (Oksifluorfen, peleton), C (Etil pirazosulfuron, peleton), D (Sulfentrazon, peleton), E (Oksifluorfen, kanton tavi), F (Etil pirazosulfuron, kanton tavi), G (Sulfentrazon, kanton tavi). Each treatment was repeated 4 times. The data were analyzed used analysis of variance (ANOVA), further testing used the DMRT test with a 5 % level. The results showed that the application of herbicides made from sulfentrazone, ethyl pirazosulfuron, oxifluorfen in peleton varieties and kanton tavi can suppress weed growth in the research area. The best weed control results were shown by herbicide treatment with sulfentrazone as active ingredient in the kanton tavi variant. The best long bean production results were shown by herbicide treatment with sulfentrazone in peleton varieties. The application of herbicides with active oxifluorfen made no symptoms of phytotoxicity, but decreased the yield of kanton tavi varieties and peleton varieties.
