Abstract

This research aims to find out the effectiveness of the coconut shell liquid smoke grade c and the insecticide active ingredient broflanilide to decreased larvae eating activity, larvae mortality, the percentage of larvae transformation into pupae and imago Plutella xylostella L., as an approach that can be used in controlling P. xylostella. The research was conducted at the Laboratory of Plant Pests and Diseases Department, Faculty of Agriculture, Universitas Brawijaya. Treatment consists of controls, Liquid smoke grade c 6%, Liquid smoke grade c 9%, Liquid smoke grade c 6% + Broflanilide 0.025 ml, Brofranilide 0,025 ml and Brofnanilide 0.05 ml, with repeated 4 times and each treatment used 20 P. xyostella larvae. The data obtained were analyzed ANOVA and DMRT with a 5% error level. The data larvae mortality of 1 hour after treatment and transformation larvae into imago were analyzed using Kruskal Wallis. According to the results of the study, there are 3 compound with the highest percentage that potential in controlling P. xylostella namely phenol, guaiacol, and syringol. The treatment that showed the best results on larvae mortality was found in the treatment of the mixture of Liquid Smoke grade c 6% + Broflanilide 0.025ml (81.21%) and broflanilide 0.05 ml treatment (86.85%). The mixture treatment decrease in eating activity up to 78.51%, the mixed treatment had an 16.25% in the percentage of larva transformation into pupae and 13.75% in the percentage transformation of the larva into imago.

Abstract

Lime is popular in Indonesia as an alternative treatment for cough and sore throat. Global production declined by 316,000 ton in 2021-2023 due to Citrus Tristeza Virus (CTV) attack, which is detrimental to citrus farmers. Effective preventive controls to suppress CTV attack include planting resistant varieties, insect vector control, cross-protection, and the use of Plant Growth Promoting Rhizobacteria (PGPR) or other beneficial microbes. This study aims to determine the effect of PGPR on the incubation period, intensity of CTV attack, chlorophyll content, and growth of lime seedlings. This research was conducted using a completely randomized design (CRD) with 8 treatments and 5 replications. The methods used were PGPR application and CTV inoculation on lime seedlings. The results showed that the application of PGPR Bacillus subtilis, Pseudomonas fluorescens, Azotobacter sp., and their combination was able to slow down the incubation period of CTV, suppress the intensity of CTV attack, and maintain the chlorophyll content of plant leaves due to CTV attack. However, the use of PGPR in this study has not been able to increase the growth of lime seedlings. Single PGPR has the same level of efficiency as the combination in suppressing the intensity of CTV attack.

Abstract

The Integrated Pest Management (IPM) program was implemented by the government from 1989-1998 through Integrated Pest Management Farmer Field School (IPM-FFS) activities. However, not all regions received this socialization. The uneven socialization activities regarding IPM have resulted in not all farmers having good knowledge about IPM and not all attitudes and actions taken by farmers are in accordance with IPM. Therefore it is necessary to study the evaluation of the level of success of the IPM program that has been implemented. The research was conducted in Purwoasri Village and Langlang Village by interviewing 20 farmers from each village with a questionnaire containing farmer characteristics, farming characteristics, knowledge, attitudes and actions of farmers in IPM. The data obtained was analyzed descriptively by simplifying the data to make it easier to interpret. The results of the research show that the IPM program in Purwoasri Village has been quite successful because IPM farmers are better than nonIPM farmers in terms of farming characteristics, knowledge, attitudes and actions in IPM.

Abstract

Coleopteran has a remarkable degree of environmental adaptation, allowing it to survive and reproduce in a variety of habitats. Research was conducted to determine the distribution of Coleopteran insects and the influence of commodities on the composition of Coleopteran insects. The research was conducted in May-August 2021 in Pendem Village, Batu City. Sampling is accomplished visually and through the placement of yellow pan traps and pitfall traps on tomatoes, large chili peppers, onions and cucumbers for 9 weeks. The study revealed 15 morphospecies belonging to the families Anthicidae, Carabidae, Chrysomelidae, Coccinellidae, Scarabaeidae, Staphylinidae, and Tenebrionidae which have roles as herbivore, predator and detritivore. In tomato plants 862 individuals were found, in large chili plants 1444 individuals were found, in onions plants 519 individuals were found and in cucumber plants, 697 individuals were found.

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.
