Mango is a major fruit crop of Sindh. In recent past
death in mango has caused massive losses in its production. In order to find the preventive
measures for this disease efficacy of plant extracts was evaluated in this experiment. Botanical
extracts of five plants i.e. neem (Azadirachta indica), ak (Calotropis procera), dhatura (
Nicotiana tabacum) and onion (Allium cepa) were used. These extracts
were tested in vitro in four concentrations 2ml, 5ml, 10ml, 20ml per liter of nutrient media in three
replicates using completely randomized design. The results revealed that plant extracts
considerably inhibited mycellial growth of test fungus as compared to control. Neem extract was
the most effective and it produced 84.29% inhibition followed by tobacco with 74.84% reduction
in fungal growth. Minimum reduction (53.428%) of Ceratocystis fimbriata was observed in dhatura extracts. The use of these extracts especially neem can be fruitful in eco
management of sudden death in mango

Floristic Composition of Weed Vegetation in Citrus Orchards in Aljouf Region, Kingdom of Saudi Arabia
The present work aimed to study the floristic composition and species diversity of
weed assemblages in citrus orchards in Aljouf region, Kingdom of Saudi Arabia. Floristic lists
were prepared and species coverage values were determined in 20 stands, using ten quadrats (1 ×
1 m) per stand. In total, 33 plant species belonging to 15 families and 30 genera were identified.
The largest families were Asteraceae and Poaceae (5 species for each), followed by Fabaceae (4
species), Chenopodiaceae and Polygonaceae (3 species for each). Therophytes represented the
dominant life form (66.7% of the total flora), followed by geophytes (12.1%), chamaephytes,
hemicryptophytes (9.1% for each) and phanerophytes (3%). The application of TWINSPAN
(Two Way Indicator Species Analysis) classified the weed vegetation into four groups dominated
by Plantago lagopus, Cynodon dactylon, Imperata cylindrica and Convolvulus arvensis. The
species richness for the vegetation group dominated by Plantago lagopus was significantly
higher (15.8 species/stand) than for the other vegetation groups. Shannon index and evenness did
not show significant differences among the different vegetation groups. The species richness of
citrus orchards was relatively high which could be related to the environmental heterogeneity
due to different light conditions in citrus orchards.

Effect of Casuarina Allelochemicals on Growth of Cultivated and Weed Plants
Mohamed G. Sheded, Muhammad Jahangir, Marwa R. Marghany, Ibrahim B. Abdel
The effect of allelochemicals from Casuarina cunninghamiana branchlets was assessed on the growth and metabolomic content of three recipient plants:
(cucumber), Lycopersicon esculentum Mill.(tomato) and Brassica nigra L. (black mustard). The aqueous extract delayed the germination rates of the three species with pronounced effect on B nigra and L. esculentum.The aqueous extract significantly reduced the seeds germination
percentage of B. nigra. The shoot and root lengths were reduced significantly under these concentrations and the germination index (GI) registered lower value due to the effect of the extract on root length. Under these concentrations (1-4 %) the seeds germination percentage of L. esculentum was not significantly affected but the root length was dramatically decreased. No significant change either in seeds germination percentage or in the root length up to the concentration of 4 % was recognized in .Application of allelochemicals from
germination and growth criteria but also affected the biochemical and metabolomic content in C. sativus.
Application of allelochemicals from C. cunninghamiana branchlets not only affected the germination and growth criteria but also affected the biochemical and metabolomic content in
the recipient crop species. A significant increase in carbohydrates, proteins and
was also observed in L. esculentum
and proline content was observed in both plants. Stress on germinated crop seeds resulted in a
significant decrease in photosynthetic pigmen
cunninghamiana branchets aqueous extract in both plants but the content was increased
significantly under the highest concentration in tomato. Sensitivity of the weed
allelochemicals from the donner plant may open the door to exploit
overcome the growth of weeds species associated to crop plants through using this plant as
