“…Moreover, several bioactive compounds in cashew nut shells as bioactivator could play a key role in this respect. same phenomenon was reported by Andayanie and Ermawati (2019) that cashew nutshell compounds act as antifeedant on the nymphal stage of B. tabaci. The previous study was carried out using cashew nutshell extract to cause the antifeedant effect of B. tabaci and biactivator of soybean against CpMMV.…”

“…From this study, it is evident that planting one or two corn lines with CNS extract proved to be more effective in the incidence of virl diseases. The same trend has been observed with B. tabaci on soybean plants where CNS extract had an antifeedant effect (Andayanie & Ermawati, 2019). On the other hand, Hooks and Fereres (2006) noted that the mechanism of suppression of a viral disease incidence could be expressed as follows:…”

“…The bioactive compound was assumed to play a role in increasing resistance to CPMMV infection. Other studies carried out by Andayanie and Ermawati (2019) have shown that the first to the second nymphal instar population density of B. tabaci could be reduced until approximately 90 % after using CNS extract at a concentration of 2.00 % in a screen house. The same trend has been observed with Aphis gossypii that a high-density border is associated with low population aphids in cotton crops (Gobiye et al 2016).…”

“…Bioactivators of ginger rhizome, cashew nut shell, and neem leaf extracts helped decrease the disease incidence and severity, symptoms, and virus concentration, respectively in soybean plants. Moreover, the whitefly nymphs of different stages (first to the third instar) could be suppressed by cashew nut shell extracts (Andayanie and Ermawati 2019).…”

Cowpea mild mottle virus (CpMMV) is one of the problems that can decrease soybean production. The research was conducted on the combined effects of corn in the barrier crop with plant extracts against CpMMV infecting soybean in the field. The field data was conducted using a Completely Randomized Design. The mean of disease incidence and disease severity is measured from total plants in each replicate plot on each treatment. Planting one or two of corn lines were grown at the edge four weeks before planting soybeans. Cashew nut shell (CNS), pagoda leaf, and rhizome of ginger extracts were applied using the sprayer and applied at 24 h before virus acquisition and transmission by whiteflies. The result showed that the virus incubation period ranged from 9−38 days after transmission longer than the untreated control. Planting two corn lines at the edge with CNS extract as bioactivator on soybean was the most extended incubation period of the virus and the lowest absorbance value DAS-ELISA of 0.20. There was a 73.11 % increase in the relative inhibition level of the virus. Planting corn at the edge with CNS extract proved to be more effective than soybean monoculture with CNS extract. However, soybean monoculture with CNS extract provides a better relative inhibition level of the virus (64.32 %) than planting two rows of corn on the edge combined with ginger of rhizome extract and planting two rows of corn on the edge with pagoda leaf extract as bioactivator on a soybean plant.

In Indonesia, soybean cultivation is generally planted in paddy fields after the rice harvest. However, expanding soybean cultivation is needed to make optimal dry land in the future. This study aims to obtain F7 soybean lines resistant to Soybean mosaic virus (SMV) adaptive in the dry land. In the dry land planted eleven soybean breeding lines resistant to SMV and two varieties as control. Ten days after planting (DAP), soybean plants were inoculated with SMV. The experiment was conducted in the randomized complete block design with four replicates within each area. These results showed that the GK/PI200.485-7-17 line was the most superior soybean line and the potency to develop in the dryland area because it had the highest number of branches per plant, number of filled pods per plant, and 100-seed weight. The tested line showed the highest seed yields of 2.40 t/ha, and 2.72 t/ha, in Girisubo and Sidowayah Districts, respectively. This line did not indicate any serological relationship to SMV in both locations.

Cashew nut shells were considered as a waste material of the cashew industries; therefore, we used this material as a source of antibacterial drugs and as a source of chemical constituent. Anacardium accidentale Linn (Anacardiacea family) popularly known as “Cashew”, is grown in the sandy loam soil, and has a spreading root system. Nutshell from cashew nut represents one of the major cheapest sources of non-isoprenoid phenolic lipid. This study investigated of antibacterial activities of cashew nut shell extract (CNSE). Samples were maceration by hexane, dichloromethane, ethyl acetate, methanol, and water solvent were then evaporated at 50 oC to give n-hexane, dichloromethane, ethyl acetate, methanol, and water extract. The yield were obtained was 125.54 gr (28.91 %), 11.19 gr (2.58 %), 43.15 gr (9.94 %), 2.46 gr (0.08 %), and 46.50 gr (10.71 %), for hexane, dichloromethane, ethyl acetate, methanol, and water solvent espectively. The extract was examined for bacterias, namely Bacillus subtillis, Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus, using the agar disc diffusion methods in using concentration of Cashew nut shell of 0.125%. 0.25%, 0.5 % and 1% respectively. The ethyl acetate extract and n-hexane extract of CNSE showed an antibacterial effect on B. subtillis with an inhibition zone of 10.333 mm and 9.67 mm. An n-hexane extract showed inhibition zone (11.667 mm) for S. aureus, 11.33 mm for P. aeruginosa. Methanol extract exhibited inhibition zone higher for S. aureus, followed by E. coli, P. aeruginosa and B. subtillis. Water extract did not affect the growth of E. coli. Four the ethyl acetate, methanol, hexane, and dichloromethane extract showed better antibacterial effects compared to water extract. Chemical constituents of hexane extract of cashew nut shell were investigated by GC-MS.
