This is a retrospective study of the outbreaks of foot-and-mouth disease (FMD) in Peninsular Malaysia between 2001 and May 2007. In total, 270 outbreaks of FMD were recorded. Serotype O virus (89.95 %) and serotype A (7.7 %) had caused the outbreaks. Significant differences on the occurrence of FMD were found between the years (t?=?5.73, P?=?0.000, df?=?11), months (t?=?4.7, P?=?0.000, df?=?11), monsoon season (t?=?2.63, P?=?0.025, df?=?10) and states (t?=?4.84, P?=?0.001, df?=?10). A peak of outbreaks observed in 2003 could be due to increased animal movement and the other peak in 2006 could be due to a compromised FMD control activities due to activities on the eradication of highly pathogenic avian influenza. Cattle (86 % of outbreaks) suffered the most. However, no difference in disease occurrence between species was observed. The populations of cattle (r?=?0.672, P?=?0.023) and sheep (r?=?0.678, P?=?0.022) were significantly correlated with occurrence of FMD. Movement of animals (66 % of outbreaks) was the main source for outbreaks. A combination of control measures were implemented during outbreaks. In conclusion, the findings of this study show that FMD is endemic in Peninsular Malaysia, and information gained could be used to improve the existing control strategy.  相似文献   

Dry Matter Partitioning in Linseed (Linum usitatissimum L.)     

F. U. Hassan  M. H. Leitch  S. Ahmad 《Journal of Agronomy and Crop Science》1999,183(3):213-216

A pot experiment was conducted at University of Wales Aberystwyth, UK, Frongach field station to evaluate the effects of sowing dates on the dry matter partitioning of linseed. Root, stem and capsule (boll) weight increased progressively as sowing was delayed up to third sowing (19 April) but showed a gradual decrease when sowing was further delayed. The contribution of each of the three parts to total weight did not respond to sowing date in any consistent manner. The total dry matter per plant followed a similar pattern to the dry matter of plant parts, which increased with sowing up to third sowing (19 April) and then decreased when sowing was further delayed. Dry matter accumulation per day degree > 4 °C also increased as sowing was delayed with a peak at third sowing (19 April). Dry matter accumulation per day degree is concluded to be directly related to the total day degrees received during the growth period.  相似文献

Studies on the wood-borerStromatium fulvum Vill. (Col., Cerambycidae) infestingCasuarina glauca (Casuarinaceae)     

Dr. F. A. Hassan  T. A. Omran  O. A. Badran  E. A. Gaaboub 《Journal of pest science》1988,61(1):8-11

The fungal genera associated with larvae ofStromatium fulvum were isolated externally, internally and also those from larval galleries and exit holes. They belonged to six genera:Penicillium, Trichoderma, Helminthosporium, Aspergillus, Rhizopus andChaetomium. Based on the antagonistic effect,Trichoderma andChaetomium were used in the mortality studies. Isolation of fungi from inoculated dead larvae proved thatCheatomium spp. are non pathogenic. The genera ofTrichoderma spp.,Aspergillus spp. andPenicillium spp. were pathogenic and are recommended as biological control agents forStromatium fulvum larvae.  相似文献   

Comments on the method to test side effects of pesticides on the predatory mitePhytoseiulus persimilis Ath.-Hen     

L. Samsøe-Petersen  Dr. S. A. Hassan 《Journal of pest science》1991,64(6):115-117

A paper published byKniehase & Zoebelein (1990) describes a new laboratory method to test the side effects of pesticides on the predatory mitePhytoseiulus persimilis and criticizes the laboratory test developed by the International Working Group pesticides and beneficial organisms of the International Organization for Biological Control (IOBC), West Palaearctic Regional Section (WPRS). The present publication discusses the advantages and disadvantages of both methods, responds to the criticism and mention the overall concept of the IOBC/WPRS Working Group including semifield and field test methods.

Zusammenfassung In einer Arbeit vonKniehase undZoebelein (1990) wird ein neues Laborverfahren zur Prüfung der Nebenwirkung von Pflanzenschutzmitteln auf die RaubmilbePhytoseiulus persimilis beschrieben. Die genannten Autoren äußern sich kritisch über das seither von der Arbeitsgruppe Pflanzenschutzmittel und Nutzorganismen der International Organization for Biological Control (IOBC), West Palaearctic Regional Section (WPRS) praktizierte Verfahren. In der vorliegenden Arbeit werden die Vor- und Nachteile der beiden Prüfmethoden diskutiert. Einer Reaktion auf die Kritik folgt eine kurze Beschreibung der gesamten Konzeption der genannten Arbeitsgruppe, die auf einer Kombination aus Labor-, Halbfreiland- und Feldprüfverfahren beruht.

Depth Distribution of Soil Organic Carbon Fractions in Relation to Tillage and Cropping Sequences in Some Dry Lands of Punjab,Pakistan     

Asma Hassan  Shahzada Sohail Ijaz  Rattan Lal  Safdar Ali  Qaiser Hussain  Muhammad Ansar  Romaan Hayat Khattak  Muhammad Sharif Baloch 《Land Degradation \u0026amp; Development》2016,27(4):1175-1185

Depth distribution of soil organic carbon (SOC) fractions depends on the efficiency of agro‐technical managements. Information on depth distribution of SOC fractions mostly confined to the plow layer and scant in dry lands of Punjab, Pakistan. Therefore, a field experiment was laid out with moldboard plow (MP) (control), tine cultivator (TC), and minimum tillage (MT) as main plots, and cropping sequences fallow wheat (Triticum aestivum L.), (FW, control), mungbean (Vigna radiata L.) wheat (MW), sorghum (Sorghum bicolor L.) wheat (SW), green manure wheat (GW), and mungbean‐chickpea (MC) (Cicer arietinum L.) as sub‐plots. Treatment effects were assessed for microbial biomass carbon (MBC), potentially mineralizeable carbon (PMC), particulate organic carbon (POC), dissolved organic carbon (DOC), HCl insoluble carbon (HIC), and stratification ratio (SR) in Rawal series: Udic Haplustalf. Alfisols. The MBC concentration was the highest in MT system, at 15 to 30‐cm depth under MW and PMC concentration was highest under SW with MT at 45–60 cm. MP had higher POC in FW sequence. The highest DOC was at 0 to 15‐cm depth under MC with TC and stock of HIC was more under TC with FW sequence. The highest SR of PMC was under MT with FW at 0–15:15–30 and POC was under TC and MP with FW at depths of 0–15:45–60 cm. The highest SR for DOC was under MP with GW at 0–15:45–60 cm and HCl insoluble C was under MT with SW at 0–15:45–60. In broad‐spectrum, labile organic fractions revealed differential sensitivity, and POC stocks are also a sensitive indicator to detect the short‐management effects.

Rapid differential pulse polarographic determination of tiaprofenic acid     

M E Mohamed  A A Wahbi  E R Gad-Kariem  M M Hassan 《Journal of the Association of Official Analytical Chemists》1984,67(4):684-687

Tiaprofenic acid (Surgam) has been determined directly by using differential pulse polarography (DPP) and pH 5.5 acetate buffer as a supporting electrolyte. The differential pulse polarogram was obtained under constant amplitude pulses of 50 mV superimposed on a linearly increasing dc ramp. Peak current was measured at the peak potential of -0.990 V vs Ag/AgCl reference electrode. Under the experimental conditions used, a linear relationship between peak current and concentration was established over the range 0.5-5.0 micrograms/mL. Mean percentage recoveries for tiaprofenic acid in authentic and tablet forms were 100.27 +/- 2.25 and 99.45 +/- 1.44, respectively. The results obtained by the DPP method were compared with those of the spectrophotometric method used by the manufacturer for the analysis of tiaprofenic acid and its tablet form.  相似文献
