Aaptos suberitoides has been reported to have potential as antibacterial against Vibrio harveyi in vitro. This study aims to study the toxicity effect of Aaptos suberitoides extract on tiger shrimp Penaeous monodon post larvae. The toxicity study of this extract was done by using soaking method. This experiment used Completely Randomized Design with 6 treatments of A.suberitoides extract namely A). 0 ppm, B). 31.3 ppm, C). 62.5 ppm, D). 125, E). 250 ppm, and F). 500 ppm. Each treatment consisted of 3 replications. Findings showed that A.suberitoides butanol extracts at the concentration up to125 ppm were safe for tiger shrimp post larvae. On the other hand, the higher concentration of that gave a toxic effect on the post larvae. The lowest mortality (20.0%) was obtained on the post larvae treated with butanol extract at the concentration of 31.3 ppm and the highest was found at the concentration of 500 ppm (97.0%). Compared to the negative control (0 ppm), there was no any difference exhibited by the post larvae treated with butanol extract at the concentrations of 31.3, 62.5, and 125 ppm. Beside that, these concentrations gave a normal growth and no abnormal behavior. The histological observation did not also show damage on post larvae haepatopancreas tissue.

<p>Normal growth medium is not effective for in vitro conservation due to the risk of somaclonal variation that may increase due<br />to short interval between subculture. Two experiments involving growth retardant paclobutrazol (PBZ) were conducted to<br />reduce explants growth and extend subculture interval. In order to develop medium-term conservation of cassava, the<br />recovery of plantlets after in vitro storage was also observed. Accession 433 and 450 were used in two independent<br />experiments. Completely Randomized Design was used with three replications. PBZ at 0, 3.4, 6.8, and 10.2 μM were<br />supplemented onto MS medium + arginin 100 ppm. Observation was done on shoot length, number of nodes and leaves, and<br />number of white and senescence leaves. The results showed that after nine months without subculture, both cassava<br />accessions showed different results in in vitro growth and their recovery. PBZ 3.4 μM performed as the best treatment in<br />accession 433 and 450 to reduce in vitro growth and their recovery after storage.</p>

The objective of this study was to evaluate the efficacy of the active ingredient abamectin, either in isolation or in combination with fungicides and insecticides formulated for the industrial seed treatment, on the population of Meloidogyne javanica, tested under greenhouse and in vitro conditions. In both tests, the combination of the following treatments was assessed: abamectin; thiamethoxam; fludioxonil + metalaxyl-M + thiabendazole. Water was used as control for the in vitro assay, whereas under greenhouse conditions, controls were inoculated and not inoculated with M. javanica. The tests were conducted in a completely randomized design with six (in vitro) and ten (greenhouse) replicates. For in vitro studies the effect on hatching, motility, and mortality of juveniles of M. javanica was evaluated. Under greenhouse conditions, the soybean ‘BRS 133’ seeds were treated, and at 15, 30, and 60 days after inoculation (DAI) with M. javanica, plant measurements were recorded. The penetration of second stage juveniles (J2) was also evaluated at 15 DAI. At 30 DAI, galls, egg masses, nematodes/g of root, and final population were evaluated. At 60 DAI, the final population of nematodes in the roots was quantified. The treatments containing abamectin were the most effective in diminishing the hatching of juveniles. All treatments had an effect on nematode motility when compared to the control, and in the treatment containing only abamectin, total juvenile mortality was observed. In greenhouse conditions, at 15 DAI, the treated soybean plants had the highest root mass and shoot length, differing statistically from the inoculated control. All treatments reduced the number of nematodes per gram of root, differing from the control. At 30 DAI, treatment efficiency was observed in reducing the final population of M. javanica, particularly the treatments using abamectin, and abamectin + thiamethoxam + fludioxonil + metalaxyl-M + thiabendazole. However, at 60 DAI, the effect of the treatments on the population of M. javanica did not persist.
