Abstract

Peanut mottle virus is one of peanut production constrain worldwide. It is transmitted by aphid vectors and by seeds. One of the efforts to manage viruses is by using plant extracts. This study aims to test the potency of moringa and bougainvillea leaf extract to suppress mottle virus infection in peanuts. The test consisted of four treatments: healthy control, untreated control infected by the virus, moringa, and bougainvillea leaf extracts treatment infected by the virus. The disease assessment and agronomic parameters were observed weekly. The results showed that the spray application of moringa and bougainvillea leaf extract showed lower disease incidence, significantly able to prolong the incubation period, decreased disease severity, and as well as virus titer significantly in comparison to the control. The area under the disease progress curve among leaf extract treatments was significantly different but was significantly lower in comparison to untreated control infected by the virus. The germination percentage, vigor index, and plant height were not significantly different among treated plants and control, except for the leaf numbers. In addition, the growth vigor of treated plants was better than the control. These indicate that both plant leaf extracts have antiviral activity and the ability to improve plant growth.

Abstract

Yard-long bean production in Indonesia has declined due to environmental factors and pest infestations, particularly by Aphis craccivora, a vector of viruses such as Bean common mosaic virus (BCMV). Generally, A. craccivora has been controlled using insecticides; however, their use poses limitations including toxicity, the development of resistance, environmental concerns, and disruption of pest–predator dynamics due to excessive application. As a promising alternative, chitosan has demonstrated potential in inhibiting aphid feeding, reducing reproduction rates, delaying disease incubation periods, and lowering BCMV titres. This study assessed the effects of both pure and commercial chitosan on A. craccivora in yard-long beans. The evaluation focused on antixenosis, antibiosis, and insecticidal properties. The results showed that chitosan significantly reduced aphid colonisation and feeding preference, lowered infestation intensity, and enhanced natural predation. Furthermore, chitosan treatments suppressed aphid reproduction, prolonged the aphid life cycle, and decreased their growth rate. The direct spray method was found to be more effective than the systemic application. Among the treatments, KK 0.9 consistently produced the most favourable outcomes across all parameters, indicating its potential as an effective bio-insecticidal agent for pest and disease management in yard-long bean cultivation.

Abstract

Tobacco (Nicotiana tabacum L.) is an important agricultural product in Indonesia. Disease information on tobacco is required to develop effective control methods for supporting a proper tobacco farming system. This study investigates the disease type and intensity of tobacco in monoculture and polyculture cropping systems in Patebon District, Kendal Regency, Central Java. Disease evaluation factors such as types of symptoms, disease incidence and severity, and crop productivity under both crop systems were measured on tobacco every week for four weeks from 14 to 17 weeks after planting, as well as during harvest. Microscopic observation was used to identify the causative infections. The findings revealed that the disease makeup differed amongst crop systems. The leaf curl (Tobacco leaf curl virus) and mosaic (Tobacco mosaic virus) diseases were discovered in both cropping systems. However, anthracnose (Colletotrichum sp.) and leaf spot (Cladosporium sp.) were only observed in monoculture farming systems, whereas wildfire (Pseudomonas syringae pv. tabaci) was only identified in polyculture farming systems at a low incidence. In general, disease incidence and severity were higher in monoculture agriculture systems than in polyculture crops. Furthermore, the policulture crop system had a slightly higher yield, indicating that tobacco would be better planted in polyculture than monoculture crop systems.

Abstract

Groundnut (Arachis hypogaea L.) is one of the food crops that has high economic value. However, one of the constraints to groundnut production is the stem base rot (Sclerotium rolfsii) and rust (Puccinia arachidis) diseases. Liquid smoke is known to have antimicrobial activities that need to be further studied for their potential to control various types of pathogens. This study aimed to test the ability of liquid smoke from empty palm bunches in controlling S. rolfsii and P. arachidis in vitro. The phytotoxicity of liquid smoke to seeds was tested using a rolled paper test established in plastic. Antimicrobial activity was tested by using the poisoning medium method against S. rolfsii, while spore germination test against P. arachidis was conducted by direct liquid smoke dripping onto uredospore on object glass. Antimicrobial activity of liquid smoke at concentrations of 0.1%, 0.5%, 1.0%, 1.2%, and 1.4% showed growth inhibition of S. rolfsii by 2.0%, 5.4%, 35.0%, 78.8%, and 100%, respectively. At 24 hours after treatment, the effect of liquid smoke on P. arachidis spore germination at concentrations of 0.1% and 1.0% was 1.7% and 0.0% when compared to the control, 8.4%, and at 48 hours after treatment was 1.5% and 0.0% compared to the control, 9.7%. It indicates the ability of liquid smoke as an antifungal.

Abstract

Aphid-borne viral infection is a major limiting factor for groundnut production in South Sulawesi, Indonesia. The study aimed to elucidate the effectiveness of integrated management packages (IMP) in controlling aphid-borne viruses infecting groundnut in the field. Field trials were conducted in a plot without (M0) and with plastic mulch and maize as a plant barrier (M1), while two different groundnut varieties, Bougainvillea leaf extract, and insecticides were incorporated as the subplot treatments. The treatments in M1 plot significantly reduced the aphid population (17.4–79.9%) and AUDPC incidence (51.7–87.3%), and severity (61.0–92.9%), respectively. The treatments increased dry pod production by 11.9–63.3% depending on subplot treatment compared to treatments in the M0 plot (p>0.05). Bean common mosaic virus strain PSt and Cowpea Polerovirus 2 were positively detected in groundnuts as well as in aphids using RT-PCR. Further, nine weed species in the vicinity of the field trial were found to be positively infected with BCMV-PSt, indicating their crucial role as reservoir hosts. Interestingly, the effectiveness of Bougainvillea leaf extract treatment in the M1 plot was comparable to that of the insecticide treatment, indicating that this IMP is a more cost-effective, eco-friendly groundnut virus control than the currently used method.

Abstract

Aphis craccivora is one of the important pests on yard long bean. It causes direct damage and also has an indirect effect as insect vector of the Bean common mosaic virus (BCMV). The research was done to test the effectiveness of chitosan in suppressing aphid population growth, feeding preference and its ability in transmiting BCMV. Chitosan with concentration ranging of 0.1–1.0% were applied on leaves using spraying method at 1 day before BCMV transmission. BCMV was transmitted by using 3 individuals of viruliferous aphids on each plant. Results show that chitosan treatments on leaves or plants significantly suppressed the population and feeding preferences of A. craccivora. Further, treated plants showed lower disease incidence, severity and BCMV titre significantly compared with untreated control plants. The positive effects of chitosan in suppressing population growth as feeding preferences and BCMV transmission might be due to the anti-feedant effect of chitosan on A. craccivora. Based on the result, chitosan at concentration 0.9% is the most effective concentration in suppressing BCMV and its vector A. craccivora.
