The Mango is classified as an evergreen and is in the Anacardiaceae family. It is the most important fruit crop of Sindh Province, Pakistan. The area under cultivation in Sindh is approximately 49983 hectares and the yield 352424 tonnes. In a survey of ten localities of Hyderabad and Karachi districts of Sindh, nine genera of nematodes and ten species were recorded. The population densities were measured and highest density was that of Tylenchorhynchus sp. (65/200 cm3). The effect of four plant extracts namely neem, marigold, eucalyptus and ashwagandha on the yield and nematode population...

Rice is the most important food crop of the world being staple food for more than half of the world's population. Rice is nutrient dense and contributes over 15 vitamins and minerals. It is an excellent source of complex carbohydrates. Essential amino acids are present in Rice which the human body cannot manufacture on its own. It also contains resistant starch which encourages growth of beneficial bacteria. It is infested by a number of pathogens including nematodes. During the present study eight nematode species were isolated from three varieties of rice. Different organic soil amendments...

An extensive survey was carried out for isolation of plant parasitic nematodes associated with date-palm of Lasbela district, Balochistan, Pakistan. Lasbela was notified as a district in 1954 with Uthal as its headquarters. The district is situated on the southern coast of Balochistan between 24 53 to 25 42 North latitudes and 65 15 and 67 27 East longitudes. The date-palm trees in the district were infested by a number of pathogens including nematodes which eventually reduce its yield. A total of six nematode species were recorded. For control poultry manure and oil-cakes were evaluated for...

The date-palm fruit is known as "heavenly fruit" because of its mention in religious scriptures. It contains rich carbohydrates, vitamin B and D, calcium, potassium, iron and other tonic ingredients. It is infested by a number of pathogens including nematodes which eventually reduce its yield. During the present studies eight nematode genera were recorded from the date-palm rhizosphere soil. The influence of soil amendments with plant species Lantana camara, Mirabilis jalapa, Catharanthus roseus, Oscimum basilicum and Tagetes erecta was studied in detail. The information is useful for plant...

Chilli is an important cash crop in Pakistan and is grown on a large scale in the Province of Sindh. Chilli are excellent source of vitamin A, B, C, E and P. Processed form of chilli retain most of their vitamin C content except for dried ones. It is exported from Pakistan in different forms: fresh chilli, stalkless chilli, green chilli, chilli powder, etc. A number of nematodes were found associated with chilli rhizosphere soil. Management strategies and cropping sequences including chilli are studied in detail. The information is useful for nematologists, plant pathologists, students,...

Wheat is a staple food crop of Pakistan, dominating all crops in acreage and production. It is cultivated in all the four provinces of Pakistan viz. Sindh, Balochistan, Punjab and Khyber Pakhtoonkhwa. The major production area is in Punjab (71.17%), followed by the Sindh province (13.38%). The crop Diseases Research Institute, PARC, University of Karachi has been conducting regular trials on control of nematodes associated with wheat using chemical and organic amendments which have given encouraging results and are being presented in this book for the use of nematologists, researchers,...

In Pakistan maize (Zea mays L.) is the third important cereal crop after wheat and rice. Maize accounts for 4.8% of the total cropped area and 3.5% of the value of agricultural output. The grain and fodder yield is reduced by a number of diseases including plant parasitic nematodes. Nematode pathogenicity trials, organic and chemical control measures have been discussed in detail. The information is useful for nematologists, plant pathologists, students, teachers and research workers in this field.
