A survey of plant species inhabiting oil palm trees was conducted in Zawlpui area of Serchhip district, Mizoram. The study area is a tropical potent agriculture zone, wherein small-scale business of Elaeis guineensis plantation is carried out by several farmers mainly within the gentle sloppy terrain. Oil palm with a rough bark harbors immense inhabitation by a variety plants, that rooted mostly on the debris at leaf base. Species diversity on the plant stem supposedly encourage insects and termites to establish herewith, thus causing harming to the tree. The sample stands within 400 m–800 m altitude were picked randomly. A total of 50 palm tree were accounted and all associated plants on the stem above 30 cm from the ground are all recorded. Species that cannot be identified on the site were pressed and observed at Botany Research lab, Pachhunga University College. The survey documented 38 vascular plant species which include 4 epiphytes and 1 non-vascular species of lichen, 1 bryophyte and 4 fungal species at that time. Invasive Peperomia pellucida and epiphytic pteridophytes Nephrolepis biserrata was found in most of the stand sample; however, Peperomia population decreases with the increasing elevation. Dynamics of inhabitant species diversity also correlate to location of tree. The study also established that diversity of inhabiting species was comparatively high on parts of the stem facing sunlight.

Abstract Elaeis guineensis Jacq. (Arecaceae), the oil palm tree, serves as a phorophyte for many different groups of organisms, someof whichhelp decompose organic matter comingfromthe organs of the tree itself or fromremainsof other plants retained in leaf sheaths. To study the myxobiota of E. guineensis, we examined living and dead trunks, leaves, bracts and inflorescences in the Gurjaú Ecological Reserve, in the township of Cabo de Santo Agostinho, Pernambuco, Brazil. Incidence and species abundance were determined in three Atlantic forest fragments. The reported species are listed herein, followed the known distribution of each species in Brazil, and which of them occur on palm trees. All of the subclasses and five orders were recorded and 22 species were added to the list of myxomycetes associated with oil palm trees in Brazil. The highest incidence value was recorded on dead leaves. Ceratiomyxa fruticulosa (O. F. Müll.) T. Macbr., Arcyria cinerea (Bull.)Pers. and Physarum compressum Alb.& Schwein. werethe most commonspecies, while Hemitrichia serpula (Scop.) Rostaf. ex Lister showed the highest levels of abundance and incidence, thus confirming its preference for the substrates provided by palm trees.

This field experiment was carried out to evaluate the weed species distribution in the experimental plots of an intercrop of juvenile oil palm trees (Elaeis guineensis Jacq.) with maize (Zea mays Linn.), okra (Abelmoschus esculentus Moench) and pepper (Capsicum annuum var. abbreviatum). This was carried out during the cropping season between July and October 2012. The crops were intercropped with the juvenile oil palm trees of about 3-years-old. The experiment was laid out in a completely randomized block design with five (5) replicates. The treatments comprised of intercropping distances of 1 m, 2 m and 3 m each for the three (3) crops (maize, okra and pepper) and a plot for each of the three (3) arable crops without oil palm trees as control. Weed species distribution was carried out in each of the plots to determine the Simpson’s Diversity Index (D), Simpson’s Index of Diversity (1-D) and Simpson’s Reciprocal Index (1/D). Weed species’ frequency, density, relative density, relative frequency, importance value, abundance, dominance and relative dominance were also computed from data collected at 3WAP and 6WAP. The results showed that the control plot has the highest weed species distribution at 3WAP having the lowest Simpson’s Diversity Index (D) of 0.0930. Okra plot has the least weed species distribution with the highest Simpson’s Diversity Index (D) of 0.2726. At 6WAP, the pepper plot has the highest weed species distribution having the lowest Simpson’s Diversity Index (D) of 0.1741. Control plot has the least weed species distribution with highest Simpson’s Diversity Index (D) of 0.2831.

We found that weeds most frequentIy visited by insects were, in descending order, the species of Asteraceae, Euphorbiaceae, Leguminose and Malvaceae. Of those, 23 were annuals and 38 were perennials. The annual plants flowered during the dry season and the perennial during various periods along the year. Most ofthose species grew in fields with young oil palm trees without the "Kudzu" cover, as well as on roadsides, along canal s and drainage and on clearings inside adult plantations. Some perennial plants with extra-floral glands, growing in fields with adult oil palm trees, proved to be very attractive to insects. The increase in the arthropod population (including beneficial insects), can be obtained through a conservative management of the vegetation. We point out the need to support such changes in the vegetation, based on ecological studies, in order to avoid favoring damaging insects and or pathogenic agents, and also in order to evaluate the effect of such measures over health and yield of the crop.

Some soils of coastal plain sands in South Southern Nigeria were assessed for oil palm and coconut cultivation. This research was carried out to evaluate the soils of the study area using rigid grid soil survey methodology at detailed scale. The study area (128.11 ha) was delineated into four soil mapping units based on soil type. A pedon was sunk in each mapping unit and described according to FAO. Three soil orders, including Entisols (Ahiara), Inceptisols (Kulfo) and Ultisols (Orlu), were identified. Parametric and limitation methods of land suitability evaluation were used. Major limitations to assessment were climate (mean annual temperatures) and soil physical properties (texture/structure). Aggregate suitability rating (both actual and potential) showed that Ultisols (pedons 3 and 4, covering 56.73 ha) was moderately suitable (S2) for coconut and marginally suitable (S3) for oil palm, Inceptisols (pedon 2, covering 54.25 ha) was marginally suitable (S3) for coconut but not suitable (NS) for oil palm, and Entisols (Pedon 1covering 17.13 ha) was not suitable (NS) for any of the crops. Thus, area with Entisols should not be used for cultivation of any of the crops due to major limitation in texture. Moreover, both assessment approaches captured the major limitations. Therefore, the use of any of the approaches employed in this study and for these crops becomes a matter of choice as both of them showed no major differences in the application of their procedures.

Plant Pathogenesis

Oil palm (Elaeis guineensis Jacq. and Elaeis Oleifera Cortes) is one of the most important oil crops in the world. Colombia is the fourth-largest oil palm producer worldwide. However, oil palm diseases are a significant factor affecting yield. Thielaviopsis paradoxa (De Seynes) Höhn is a pathogen that affects young palm trees, causing spear rot. Four disease establishment methods were studied to replicate, in a controlled environment, the symptoms of the disease found in the field. Young palm trees were inoculated with a suspension of endoconidia using either local infiltration, drip, scissor cut, or direct contact with agar blocks bearing mycelia and conidia. The effects of the inoculation methods were studied in dose-method-disease severity experiments conducted in a greenhouse under controlled conditions. All four methods resulted in T. paradoxa infections and the development of symptoms of the disease. The disease severity was correlated with the method and dose of inoculation. In trials to test Koch’s postulates, T. paradoxa was isolated from areas of disease progression in the inoculated trees, but the teleomorph Ceratocystis paradoxa (Dade) Moreau was not observed. A photographic record of the infection process at different times post-infection was compiled. Given that establishing the disease through artificial inoculation is essential for assessing plant pathogenesis, this study determined that the local infiltration method (1 × 106 endoconidia mL−1) and a 3–7 day incubation period were critical for the development of symptoms as severe as those observed in natural infections in the field.

Rot Disease

The South American palm weevil (SAPW), Rhynchophorus palmarum Linnaeus (Coleoptera: Curculionidae) is the main pest of Elaeis guineensis and damages palm trees with bud rot disease in the Americas. The effects of six neurotoxic insecticides (abamectin, carbaryl, deltamethrin, fipronil, imidacloprid and spinosad) were evaluated against SAPW for toxicity, survival, reproduction, and mortality. Abamectin (LC50 = 0.33 mg mL−1), Carbaryl (LC50 = 0.24 mg mL−1), deltamethrin (LC50 = 0.17 mg mL−1), and fipronil (LC50 = 0.42 mg mL−1) were the most toxic to SAPW. Adult survival was 95% without exposure to insecticides, decreasing to 78–65% in insects treated with the LC25 and 49–35% in insects exposed to LC50. Sublethal doses of carbaryl, fipronil and imidacloprid showed significant effect on the reproduction of this insect. Mortality of SAPW populations caused by insecticides had similar effects in the laboratory and field conditions. The results suggest that carbaryl, deltamethrin, fipronil, and imidacloprid caused significantly higher mortality as compared to the control in SAPW and may be used to control its populations in oil palm trees where bud rot appears as the key disease for SAPW attraction and infestation.
