Nematodes are commonly referred to as non segmented round worm, thread worms or pin worms. It‟s body is elongated, cylindrical, bilaterally symmetrical and tapering towards both end. It is pseudocoelomate and dioecious with sexual dimorphism. It‟s impact on agriculture by way of inflicting is quite substantial. In the District Bilaspur of Himachal Pradesh, in the present study on nematodes, two...

Begomoviruses are plant-infecting viruses, which are transmitted by the whitefly vector Bemisia tabaci. They have a genome of single-stranded DNA that consists of either a single (monopartite) or two components (bipartite) with a component size of approximately 2.8 kb. Many monopartite begomoviruses in the Old World have been found to be associated with betasatellite and alphasatellite molecule...

bemisia tabaci (homoptera: aleyrodidae) is one of the most important pests of cotton in khorasan which causes crop damage and yield reductions as a result of direct feeding of plant and passing pathogenic viruses. using resistant varieties is an economic and environmental friendly method for controlling this pest. the resistance of seven cotton varieties (green leaf okra, red leaf okra, mehr, v...

Subsurface drip irrigation is defined as application of water below the soil surface through emitters, with discharge rates generally in the same range as surface drip irrigation. It has many advantages over surface drip. To see the response of subsurface drip irrigation on okra yield, a study was conducted at Indian Agricultural Research Institute, New Delhi, India during 2003 and 2004. Okra (...

The efficacy of clean fallow, bermudagrass (Cynodon dactylon) as a rotational crop, and fenamiphos for control of root-knot nematode (Meloidogyne incognita race 1) and soilborne fungi in okra (Hibiscus esculentus), snapbean (Phaseolus vulgaris), and pepper (Capsicum annuum) production was evaluated in field tests from 1993 to 1995. Numbers of M. incognita in the soil and root-gall indices were ...

To evaluate the effectiveness of selected insecticides and a botanical extract in management of okra shoot and fruit borer, Earias vittella an experiment was conducted in the field Laboratory, Department of Entomology, Bangladesh Agricultural University, Mymensingh during January to May 2011. Effectiveness of two synthetic insecticides (Kinalux 25 EC and Ecofuran 5 G) and a botanical (Neem leaf...

Our objective was to compare some plant growth promoting rhizobacteria (PGPR) properties of Bacillus subtilis and Pseudomonas aeruginosa as representatives of their two genera. Solanum lycopersicum L. (tomato), Abelmoschus esculentus (okra), and Amaranthus sp. (African spinach) were inoculated with the bacterial cultures. At 60 days after planting, dry biomass for plants treated with B. subtili...

In Greece and Turkey, okra (Hibiscus esculentus L.) is cultivated for small pods (≤4-5 cm), which are highly perishable after harvest. In this experiment, okra was cultivated at 4 levels of N (30, 150, 300 and 450 mg l-1) within the irrigation water. Pod yield was highest at 300 mg l-1 N. High N increased the nitrate content and decreased dry matter without affecting pod colour (P

The control of whitefly Bemisia tabaci (Gennadius) biotype B (Hemiptera: Aleyrodidae) on okra (Abelmoschus esculentus L.) consists primarily in the use of insecticides, due to the lack of information on other mortality factors. The objective of this study was to evaluate the spatial and temporal population dynamics of the whitefly B. tabaci biotype B on two successive A. esculentus var. “Santa ...
