Abstract

Soybean pod damage caused by N. viridula reached 61.37% of the total pods and 61.67% of the total seeds attacked. Efforts were made, namely the application of chemical insecticides made from active chlorpyrifos which can reduce the population of N. viridula to reach 57.4% and the insecticides made from deltamerin which are reducing the population by 51.6%. Control is needed that can reduce the negative effects caused by chemical insecticides, one of which is mechanical control. Mechanical control can be done one of them with augmentation and conservation tools. the research is by taking the eggs of N. viridula in the field and laying the eggs in an augmentation and conservation tool with several treatments of different filter cloth diameters, 0.1 mm; 0.3 mm; 0.2 mm; and 0.6 mm. Observations were made by looking at and counting the number of parasitoids that were able to pass through the filter cloth and those that did not pass through the filter cloth, followed by identification of the species of the parasitoid that was obtained. The results showed that the parasitoids were able to escape in all treatments but with varying amounts. The difference in number can be influenced by the presence of parasitoids in the field and the level of parasitoid parasitation. Likewise with Trichogramma sp also able to pass on all treatments. Therefore, the most suitable treatment is treatment with a 0.1 mm diameter filter cloth. The identified parasites were T. rowani and T. podisi

Abstract

Sclerotium rolfsii is a pathogen that causes stem rot disease that causes a decrease in soybean production. This stem rot disease can cause damage to all parts of the plant both in the vegetative and generative phases. Proper control is needed to reduce stem rot disease by induction of plant resistance using endophytic fungi such as Trichoderma harzianum and Beauveria bassiana. This experiment used a Completely Randomized Design (CRD) with 4 treatments that were repeated 5 times, namely P1 = control, P2 = T. harzianum application + S. rolfsii inoculation, P3 = B. bassiana application + S. rolfsii inoculation, and P4 = Combined application (T. harzianum + B. Bassiana) + S. rolfsii inoculation. Based on research that has been done shows that the incubation period and phenol analysis in soybean plants did not significantly affect soybean crop resistance while in the incidence of disease and disease severity showed a very significant effect on soybean crop resistance. In this study the plants that were applied with T. harzianum and B. bassiana were included in the category of resistant to S. rolfsii pathogens, while the control treatment was included in the susceptible category to S. rolfsii pathogens.

Abstract

Watermelon is one of the plants that have good prospects and has high economic value, but its production is currently experiencing a decline. Decreased production caused by the pathogen Fusarium oxysporum which causes fusarium wilt disease in plants. losses caused by fusarium wilt attacks reach 20-30%. Utilization of Gliocladium sp. and vermicompost is an alternative step in controlling fusarium wilt. The results showed that the use of Gliocladium sp. and vermicompost can suppress the development of fusarium wilt disease. The use of Gliocladium sp. and vermicompost 250 grams/polybag can suppress the attack of fusarium wilt disease with a percentage of suppression of the incidence of disease by 70% and suppress the severity of the disease by 38.5% compared to controls. and has a control effectiveness value of 73.68% which is categorized very well. The use of Gliocladium sp. and vermicompost also affect plant growth and production.

Abstract

Fusarium wilt caused by F. oxysporum, is a disease that often attacks melon plants. F. oxyporum is a fungus that infects through the roots and clogs vascular vessels in plants and causes plants to wither with necrotic symptoms. Bacillus spp as a biological agent capable of controlling fusarium wilt by antibiotic mechanism. Bacillus spp obtained was then carried out by testing to determine its potential as a biological recognition agent. This research was carried out starting from the isolation of F. oxysporum, isolation and inoculation of Bacillus spp., Gram test, hypersensitivity test using tobacco plants, to calculate the intensity of attacks and analyze. The study was conducted with 5 treatments namely control, F. oxysporum without Bacillus spp., F. oxysporum with isolates BJM4, BJM5, and BJM9. The results showed that BJM5 isolates can suppress fusarium wilt disease with a disease severity value of 23.75%, the lowest compared to all treatments applying Bacillus spp. this was also shown by the results of antagonistic tests on PDA media that BJM5 isolates could suppress F. oxysporum fungi by 0.6 or 60%.

Abstract

Bacterial biopesticide formulations needed because the use of bacteria in the suspensions can reduce the ability to control disease in plants. Therefore, a bacterial suspension needs to be mobilized in the formula with a carrier (Carrier) to maintain the viability of bacteria. This research uses the formulation of Bacillus sp. made from rice flour, corn, tapioca and talc with the addition of urea, glucose and CMC. Formulation of Bacillus sp. flour based with the addition of urea, glucose and CMC were tested with Xanthomonas axonopodis pv. glycines and Colletotrichum sp. in vitro. The results showed that Bacillus sp. after formulation it is still able to maintain viabiitas and antagonistic power. Viability of Bacillus sp. the best is in the formulation of rice flour at 14 hsi at 4.94 X 1014 cfu / g while the inhibition zone of Bacillus sp. the best is the corn flour formulation of 13.1 mm and the inhibitory capacity of Bacillus sp. the best is in tapioca flour formulation at 42 hsi at 62.89%
